- The long awaited reassembly video of the Rincon 680. In this video I show how to install the transmission, rebuild the oil pump, replace the first gear clutches, install the rings, and adjust the valves.
Also check out my two other videos I have for this bike where I removed the engine • Honda Rincon 680 Motor... as well as a video where I tore the motor down • Honda Rincon 680 Engin... . Enjoy!
We need more people like you!!! Keep the videos coming….
Thanks and thanks for watching
Great job! Replacing timing chain and this video helps a ton!
Great videos! I think it’s funny that you bothered with the timing mark on the crank when you’re looking at the piston at the top of cylinder. 😂
Well it can be 180 degrees off. The piston can be at the top on the exhaust stroke. It seems like most of the people on here have questions or fears about timing so I try to cover it on all my engine video. Thanks for watching.
Awesome video! Saved me a ton of trouble over here. Might make the labor day ride after all!
Thanks so much for these videos cause if you I was able to buy this atv for cheap and fix it !!!!
Good job cause am rebuilding one for a friend of mine great Info
Nice video. Thanks for taking the time.
Good video the only problem I see is you should have soaked those clutches in oil before you put that clutch back together! 😁
You are correct. The manual does say to soak them but I have never noticed any difference in soaked or non soaked clutches. In all actuality the Hondamatic unit will go out in this bike before the clutches wear out again. Lol
I'd love to see the first start up video
The bike had some pre-existing electrical problems that I had to figure out before I could get it to crank. I didn't get it on video but it didn't crank up and run fine and pulled forward and reverse perfect.
Very helpful video,where are u locate it?
im doing a 2007 rincon had the wrong oil put in it and now the clutches are slipping i plan on doing 1,2,3 clutch packs but what about the torque converter will i need to replace it
Great Video. Thank you
hello doctor, I have a problem with rincon 650 2005: because it slips when I force it I changed the oil pump, after I changed the pump it doesn't change gears when the engine is started, the engine stopped changes 1,2,3-3,2, 1 no problem, I can send a video eventually, please help me
The decompression mechanism on the cam, is it supposed to be able to slide freely back and forth, or should it be firmly in place?
Hey Doc I could use your advice I have Rebuilt the Engine and it runs nicely but Now it is only getting First gear and Reverce and I am not sure what is wrong. I hope you can point me in the right direction. Thanks
I ran an oil pump pressure test on the 700 BR I'm working on. Only got 25 psi, supposed to read 114 psi,(according to the manual). So, obvious oil pump problem. After watching this video, I have come to the conclusion, that the pump design is absolutely horrible. A high pressure three rotor pump driven by a chain. The oil pump chain behind the timing chain. The oil pickup on the other side of a case, and with what appears to be very little clearance between the pickup and the bottom of the case. Yeah, what could possibly fail with this design? Good video, though, with several good tips!!!!
That's what it sounds like. The pumps aren't too bad to rebuild but they aren't the easiest to get to on the big red. I have had the chains come off before as well because they do not have a tensioner to keep them tight.
Well, according to the owner, this tranny was rebuilt 2 years ago at a Honda dealership. I'm wondering what they overlooked to get it out the door. Due to the fact that this unit doesn't have an hour meter or speedometer on it, and it's 12 years old, I'll just replace the pump. It doesn't cost that much more, and there are too many unknowns and variables not to. Thanks for your videos. Very helpful!!!
what is the part next to one of the cam lobes, it is between the holder and the lobe? mine is shifting about a quarter of an inch back and forth is that right?
That is the decompression ring. It helps to lower the compression at startup by opening a valve slightly. They do normally have some play in them.
Good job. Thank you.
I know the thread is old but I recently got a 05 Honda Rincon 650 4 x 4 and I was looking to see if there should be just a little bit of play on the oil pump sprocket? I cleaned snd replaced the O rings.
There is often play in the oil pump chain. I have replaced them with new ones before and they still have a little bit of slack in them as well.
@@FourwheelerDoctor ok thx for the reply just tryin to get this thing together more me do rent look bad inside the engine casing I seen that u can clean the torque converter with paint thinner then blow it out with air and soak it in oil for a day to make it lock encounter clockwise position on turning mine seems to turn either way
thanks,great video.
I watched your engine tear down paying attention to the clutches, do you have to tear down both sides of 680 rincon motor,to take out 2nd & 3rd clutches
Yes they are inside the crankcase.
hey. I replace a flywheel put back together and now somehow tdc is off on flywheel. how does the flywheel go back on the crank to keep from slipping . Do I hit it with rubber mallet? The keyway looks kind of slim . Help. thx
Just putting my engine together and gear selector won’t move any ideas thanks
Every get this sorted? My rincon stopped shifting on me mid ride. Was stuck in reverse. Finally got her to move to neutral. Now she wont let the gear shifter move into any other gear.
Probably going to have to pull the back cover off. It may have broke the shift drum of one of the shift forks.
@@FourwheelerDoctor thats not doable with the motor installed is it?
@@21213248 yes it is but it requires removing the rear subframe which is much easier than pulling the engine. You will need to remove the two top shock bolts the four upper control arm bolts the two upper diff bolts and the four bolts that hold the sub right frame to the frame under the engine. Unbolt the brake caliper and the rear end will fall out.
Great video! I noticed you mentioned a gear reduction was a big red gear swap? I have a 14 pioneer 700-4 I believe it has the same engine and trans as the 680. I was wondering if this reduction would work on mine! Also where are you located and how much would you estimate it would cost to change out all clutches and do the gear reduction?
Hello doc I need your help I was changing the oil pump chain in my ricon 650 and when I removed the timing chain tensioner it came out of gear and now I don't know how I will know if it ran out of time
How much play should the sprocket have on the oil pump?
I have a rincon and just rebuilt the top end and got everything set right and just turned it over a little and it ticks. I’ve narrowed it down to the lifter cup on the exhaust side kinda taps on top of the cam lobe when turned to a certain point so I took the head back off a few times then looking down the hole where the lifter cup sits it looks like the cam lobe is way off center. And the lifter cup is taping one what appears to be some sort of oil pick up on cam shaft. I can’t figure out why it would be doing this but I’m at a lost and you seem to know what your doing better than I. Any help would be greatly appreciated
Can you post a video? Sounds like you bearing or cam holder isn't quite right.
Excellent thank you
When doing your low clutch your bottom c ring is it flat like the top or is it kinda wavey also your springs on the front of the clutch are they loose when you shake the whole assembly or are they supposed to have tension the whole time?
Around how much did it cost for all the parts to rebuild it ?
You a have a diagram for the timing chain position ?
Where are you located?
Great video. Would like to ask. You happened to know mabe. My trx 680 rinco starts but its idling poorly with smoke out the exhaust and if i put it in gear the engine dies or gears are not selecting. If you can help. Would be nice.
I would start by cleaning the carb. Sounds like you may have a stopped up idle jet in the carb.
I was always taught when a rod changes colors like that its a sign of running with no oil is this true?
Sometimes. In automotive applications that is a pretty good sign since most of them use two piece bearings. But in most of these Honda ATVs they use roller bearings on their rods and I've actually had some brand new cranks that were blue from the machining process.
Timing this motor is a little weirder or stranger than other motors being that you put it at top dead center crank and you Pistons at the very top then you put your camshaft on and you put that line on and then you put your heads on or another deals you put your head on I mean you got your head and all that stuff on and you put your camshaft on and you can tell what you compression stroke by the clothes and open up the valves what are you doing this case if you don't have the compression stroke to take the heads back off and turn the cam all the way back around or something just a little strange here I'm going to watch and see how you do it but I don't know if we ever from what I've seen so far talk about the compression stroke and that's a little confusing to me on this part since I've never done a motor like this I'm doing right now but one that didn't already have the cam that goes on top of the heads itself and then you could find a compression stroke by the opening and closing of the cam at your top dead center or the open and closing of your valves because if you can at the top dead center compression stroke
Yes because this is one of the few kindof overhead cam engines that honda puts on atvs. Most of the honda engines have the cam mounted down low behind the front cover.
Punctuation exists for a reason bruh
I know this video is a little older, my rear crankcase cover has a hairline crack and i plan on replacing. Can i do this with the engine in the 4wheeler?
Yes but you will have to remove the rear subframe to get the cover out. It's really not as bad as it sounds.
Hi. can you help me solve the problem with honda rincon 680? reverse gear R engages quietly and gear D very loudly.
Oftentimes the shift drum wears out on these and causing them to engage louder. It's not a real easy fix. You don't have to split the case but the part that needs replacing is behind the rear cover
@@FourwheelerDoctor And what part is it?
@@FourwheelerDoctorI have already replaced the complete selector from D N R, on a cold engine it is ok, the problem appears after warming up
I’m needing to do a 2007 Honda rincon 680 are the the same as what your doing ?
Yes it should be exactly the same as the one in the video.
Can you change the 8 O rings for the oil pump with the engine still in the atv?
Yes you can
Your mark, is the same mark for all Honda rincon?
Yes the flywheel should be on the t mark with the line on the cam lined up with the head. Both lobes of the cam should be facing down at TDC.
Great video! I have an o5 rincon that broke the timing chain guide. When that happened it broke one of the metal pedalstals that support the back side of the torque converter. Pushes out on the converter. Its the bottom of the three, can I run it with two or do I need to somehow fix it/replace case halves... not holding you to your opinion, just wondered if you've ran into it and how or if you fixed it. THANK YOU for sharing all your knowledge!
I'm not sure exactly which part you are talking about. What time do you see it in my video?
@@FourwheelerDoctor I took a video of the motor to help illustrate what is broken. drive.google.com/file/d/1FQ3b8gI_gxU31AmbFXk7nSKtrsFYtWGU/view?usp=sharing
Should the oil pump gear be kinda sloppy on the shaft it turns?
@@stutyss1 if you are talking about the gear that the chain goes on then yes it will have some wobble to it.
@@mattstutenberg2982 I don't see where the broke stud would be an issues reassembling it without it. It looks like it just holds the back of that gear off the cam chain and since the back part doesn't move I don't think it will be a problem.
Thank you for a great video. I replaced my cam and it fixed my issue but I have a new ticking sound. At the end of ur video you said the rockers should move up and down slightly at TDC. Only the exhaust moves not the intake? Any help would be great. Thank u
Sounds like you need to adjust the valves. There should be a small amount of play in both rockers.
@@FourwheelerDoctor thank you for the response. I have adjusted the values but I still down any movement in the intake rocker…?
@@trentjarecki1899 it will be a very small amount but if the feeler gauge slid under the rocker it has to have a gap between the rocker and the valve. Is the noise still there?
Yes still have the noise. I have the proper gap between the rocker and the value at TDC. The intake rocker is still solid.
Valve
Do you have an email, website or social media where we could get in touch with you about our four wheeler?

Do you need to put anything on the base gasket
No I have had trouble with base gaskets slipping out from under the cylinder with rtv on the gasket from the head bolt pressure. I always put the base gaskets on dry.
Good day from Zambia AFRICA. My TRX680F is @ 720hours on the clock. My concern is the "TAPPING CLAPPING" low rpm noize on the engine (pobebly on cam rpm side, it sounds like a loose timing chain). I yet have to check the tappet clerance. Do you out of experiance, know what else I should check?
Greeting from South Carolina. I told my 75 year old mom that someone sent me a message about a four wheeler from Africa and she said is he going to bring it? LOL. It sounds like you're heading in the right direction. You should check the valve clearance first. Then when it's at top dead center you can remove the cam chain tensioner and let it extend out. Insert the tensioner back in to see if the tensioner bottoms out before it hits the cam chain inside the engine. If the tensioner bottoms out you need a cam chain if it doesn't bottom out sometimes these tensioners when they get extended way out do not hold pressure on the chain like they should. There are some UA-cam videos of how to increase the strength of the tensioner. I don't have one but I have one watched one before.
@@FourwheelerDoctor Buying a new one is a cheaper option than shipment...... I did check the tappet clerance, its perfect, though. I pulled the tentioner out, cleaned it and stug it back. After starting, the noiz was gon, only for 5 minutes....... 1) Have you ever had problems with a tentioner? 2) How many HOURS on the clock do the timingchain, gide and tentioner last, before failurer? (under normal HONDA working conditions)
@@johannesclaassens9519 I have had trouble with the tensioners before. If you removed the tensioner and stuck it back in without retracting it then you probably need a cam chain. I haven't ever really noticed a pattern in them as to when they fail but as the chain stretches out they will make the rattling noise because the tensioner is at the end of its throw and looses some of its pressure on the chain.
@@FourwheelerDoctor I am from Namibia Africa and my 680 rincon had the same problem. When i opened the engine the cam bearings was broken. So i put in a new camshaf
@@johannesburger7808 I can't say I've ever seen one of the bearings break because it's usually the lobes worn off. Glad you got it figured out
Hey doc. I’ve got a 12 rincon 680 I could really use your advice. No one in my area works on rincons. So I’m having to figure out what’s going on with pretty much zero guidance lol
What is going on with it?
Wife rode it while I was at work. Ran fine. Next day I went to go ride. It took longer than usual turning over. Then backfired. Violently. Plug soaked with fuel. Changed oil. Plug. Made sure I have good battery. No longer backfires. But doesn’t start. So then attempted tdc. From what I’m reading. When the t is center of the hole. My valves should be open. But it’s when the piston goes from tdc down stroke. The valves then open.
No codes or blinks. Cleaned all electrical connections. Cleaned iacv. When I say plug is soaked. It is soaked with fuel
@@billyharrison660 sounds like you might not be getting good spray out of your injector. Have you tried to clean it? I think I have a video for that lol let me look around
@@billyharrison660 also you want to make sure your spark plugs firing. Unbolt it from the head and just lay it on the head with the plug wire hooked up and turn it over to see if it sparks
Hey man, i have a problem with the closhes of the honda rincon, you can help me please?
I probably can. What problems are you having?
Look, the honda dont' run, it only stay in the place, sometimes it move but only a little
We already change the rings, and the converter
And the Honda continue with the problem
Is a Honda rincon 680
@@natsu202dragneel9 are there any lights flashing on the dash? Is the oil completely full?
No, don"t dash any light
And.. I don't remember is complrtely full
