I had my engine off my FourTrax 300 because I had to drill out and retap some bolt holes on the top head/rocker cover area. I couldn't do it with the frame in the way of the holes. Then went to put it back together and ended up screwing another bolt hole up so decided to do all the holes on the top of the head. I then noticed the timing chain was looser than I thought it needed to be so decided I would change that out while I had it off the bike. Looking at your issue with reinstalling the side cover. I'd imagine having the engine on its side would have saved you the trouble with shit lining up cause gravity is not your friend with stuff trying to hang down. Since I have my engine off the frame Im going to do it on its side so everything stays put. I appreciate the video this will help me out with what I need to remove to change the chain.
he may or may not know ?, but there is a trust washer at the back end of the kick starter shaft that almost always falls off..and down into the engine when the kick starter shafts pops out ?. be very careful not to allow the kick starter shaft come out at all !!!.
@alanshaw4655 yeah, My thought was to press inward on the shaft as I remove the cover to try and keep the shaft put. I got a question tho since you brought this up. My dumbass when removing the engine pulled the sidegear out sideways (not knowing I didn't have too as this was my first time removing one.) all the gears fell down in the left case. I did my best to line them back up and slid the shaft back in. It felt smooth and turned fine. When I was looking at the diagram of the sidegear and it appeared to have really smallparts in between some of the gears. May be shims or spacers, not sure as I didn't look down the part list on the sidegear diagram. Is there anything that could have slid far enough where it could still be out of place even though the shaft went back in. I really would hate to have to take that side off to place a piece back on the shaft if it slid far enough where the shaft didn't go through it. But it also feels so smooth so Im wondering if it was ok just sliding the shaft back in like I did. But it was in the back of my mind
I have one of these and it's the best bike I've ever had I've ran the he'll out of it since 96 and this is the first problem I've had with it other than tires and brakes
Timing chain? Brakes definitely seem to be a common issue. I have another video of installing a disc conversion on the front, which helped immensely! This was my first one but definitely a fan of it!
The engine needs to be at top dead center (TDC) compression stroke, indicated by the "T" on the flywheel. The cam has 3 marks on the gear. The center mark will be pointed up and the other two parallel with the surface of the head.
Just replaced topend of one (new piston, rings and jug) didn't replace chain- look good and fairly tight- i now have a fairly loud ticking noise? Any guesses? Plan to replace chain tensioner as it won't stay tight like it should
Easy way to check if it's the chain/tensioner. Pull the tensioner, and shit a screwdriver handle against the guide. If the noise goes away, check the tensioner. If it's springy and snaps right into full.extend it's good, chain is stretched. Have you checked the valve clearance? Could be out of spec. I'd check the tensioner/chain cause you don't have to remove the tank. Then do valves if need be.
Is their a mark to align the clutches when u put them back in or can u just put them back in and your good to go? I'm doing my timing chain on my 96 300 4x4
Question, and before I post it I’ll admit I have not the slightest clue honestly just trying to save a heck of a fourwheeler everyone has given up on. Can you test the timing like this as well?
@user-hv5kr5uf6q 2:36-3:ish in the video is where you'd want to start. Take off the gas tank and then all the 10mm bolts. Set the flywheel at TDC 16:03 in the video. And then the cam would be parallel with head with a center line pointed up. __ | __ Like that.
@@weekendwarriorpowersportsI was able to check it! Thank you so much!! In the video, you mention looking up the diagram, what exactly do I type in to pull up the exact diagram for the fourwheel? I’m Sorry, for so many questions!

Got a nice really nice four trax for $400 but the timing chain is slapping mine is 2wd but it is super clean thanks for the video man appreciate it
Good luck man! Grabbed this on for $500 this summer

Very useful video thanks! I don't think you showed what position to put the cam shaft back in? Any advice on that?

@The Weekend Warrior Garage thanks!
No problem! Be sure to subscribe if you enjoyed the video!
Make sure can lobes are pointing down and not opening valves or it will be 180 degrees off

I got ticking sound. Suspect it needs valves adjusted.
Good job
Thanks for watching and commenting!
hola buenas tardes donde consignó la diferencia para una 300
I have a 1994 Honda 300 tried to adjust valves ; I can tun the Allen had bolt clockwise but flywheel don’t move.?
Any ideas thanks
Is their a mark to align the clutches when u put them back in or can u just put them back in and your good to go? I'm doing my timing chain on my 96 300 4x4
Do you mean aligning the transmission clutch and centrifugal clutch?
No, they don't have an alignment. Just gotta get the adjuster through the case.
Question, and before I post it I’ll admit I have not the slightest clue honestly just trying to save a heck of a fourwheeler everyone has given up on. Can you test the timing like this as well?
Like take the caps off, and check and turn till I see it? I think the issue is it’s not in time even though it’s been lined up
You have to take the Rocker Cover off to check timing. The caps are just for valve adjustment.
@@weekendwarriorpowersportsthank you! I’ll check into that

Where did you buy the chain? I need one and Honda said parts are discontinued? Thanks
They're the same as 300ex. Got mine on ebay.
What chain did you use?
OE Honda. I've had good luck with the cheap ones on low RPM engines like these though.
I can’t believe you didn’t replace the chain guides while you were in there.
Why??? There was nothing wrong with them?
unless video. you don't even show replacing the timing chain.
15:02 ... what?
Idled up too high
