Thank you for the video. Superb narration, amazing audio and, wonderful camerawork. I was able to follow along and keep up with you throughout the duration of your presentation.
After watching 7 or 8 different ones on cam shafts , You have given me all the relevant information that I needed,Thanking you for the advice and information,100 %,
I'd like to add my compliment as well regarding the clarity of this video. I have watched several others and they were not as exact on the critical method of timing. Thank you!
Probably the best camshaft replacement video on a Briggs on UA-cam. Simple explanation, clear audio, clean video...just got REALLT confused when I heard your voice for a minute because I've been watching McGregor highlights this morning! 😳
Fantastic Video, right to the point. Can't thank you enough for posting it. I now have a clear understanding of the job ahead of me. I'm going for it !!!!!
The camshaft rotates once for every 2 rotations of the crankshaft. Therefore it’s possible to have the dots lined up but for the camshaft to be 180 degrees out. If like me you are unfortunate enough to have moved the crankshaft inadvertently while the camshaft is removed the solution (assuming you have tried to start the engine without success and much backfiring) is to line up the dots, then lift the camshaft and turn it as close to 180 degrees as you can, then turn the crankshaft until the dots are aligned or close to alignment. If they are out by a couple of teeth simply move the camshaft round a couple of teeth until they mesh, the timing is then correct. I found out the hard way through my ignorance.
This is very interesting to me if I manage to put my L-series engine back together and it’s 180° out of phase with this cause it to not start? What I’m getting is it attempts to start when cold in the choke is closed but as soon as it’s butter is a few times and I do mean like maybe five or 10 times I open the choke a little bit and it just dies. Also, I noticed saying that there is gas pumping out of the carburetor inlet.
@@iRepairElectronicshey I have a question for you, how is the governor held in place? It seems like I can push it off its tab it would fall off with engine rotation
Thanks for your time!! That’s exactly what happened to my engine!!’ But I wonder , I noticed on the governor, one tooth looked a Little chipped!! I hope it’s alright!!! Any tips?? Thanks again for your help and patience!!!
I have had now two of the Briggs 19hp in my John Deere E110 fail. John Deere replaced the first engine..50 hours on it. This engine lasted 53 hours..One year and a week!! John Deere told me sorry your on your own. I took it to there Corp and they told me the same thing. So glad to find this video as I will have to fix it myself....and NEVER BUY a JOHN DEERE AGAIN
If you use the mower intermittently , just take off the air filter , cover the pipe completely to cut off the air , get it spinning , pull your hand off & it will fire right up !! Been doing this for years on a 19hp Gold Series engine !!
@@jesusdrummer21 yeah I did, it's actually a simple fix once you take the motor out, use a magnet to take the metal out. An make sure you get the right governor an new seal an gasket
Looks like I m going to have to do this. New battery, starter turns motor freely when spark plug is out, and I adjusted valves, but still half turn when trying to start. Yeah my mower is only two years old. My old craftsmen I had for 15 years and never had to do this. How old is your mower? Also any extra advice or confidence booster before I start is appreciated! Thanks for video!
Hi apologies for late reply, The same ingredients are not in those cams as they used to be... its also worth checking that your batt is the correct...what mower do you have now ?
@@mickmac7264 All went well. Runs great. I had to adjust the valves 2 or 3 times before they would stay. I stripped one of the bolts to the engine cover. Wished I had used a torque wrench. See my video. Learning process. gave me confidence to fix in future.
@@bif90210 yep learn as we go,. Sometimes you've got to strip a bolt to know how far to push it. Im working on stuff daily so I've developed built in torque in my arm.. yep seen vid good job..
Briggs doesn’t make parts as well as they used to. Push mower engines have aluminum cylinder walls. That’s meant to be scrap within less than 100 hours of use. Briggs is also called Breaks and Scrap ‘em. Parts are junk. Making better parts would fix it.
Both of my valves are motionless when I crank it. Had recently replaced the flywheel because it fractured at the keyway when she struck an object in the grass. Ran fine for a week and now the valve train stopped. Piston still moves as you roll it over. Is it possible to have a broken cam or gear?
Mick have you ever had the timing gear spin on the crank? I took off the oil sump cover to watch the crank as i rotated it, and as the timing mark gets to where it should be the piston is down about an inch..any ideas will be greatly appreciated! Thanks!
I just had this happen with a B&S 331777 20hp. When the compression release on the camshaft grenaded, the shaft got jammed somehow and the attached timing gear kept turning. Actually, the timing gear spun on the shaft so hard that it spun around like a roller skate wheel. Lost all compression.
Good video, good information and to the point. Also, you forgot to put the tappets in. Hope you realized that before you put it together! Keep up the good work!
Hi Mick Maybe a Long shot. I need to change camshaft on my 2006 BG 12.5. Engine id impossible to read. It is a match to the one you have, looking at the shaft end. Do you have a cam shaft part number and maybe an engine id you can share
Thanks so much for the video! Question for you... I didn't remove my valve cover. Just went straight to removing the sump cover, replaced the camshaft, etc. Do you think I need to open the valve cover to do the timing adjustments or do you think it's fine since I didn't open it up? Working on a 2019 John Deere with only 120 hours. Thanks!
hey Mick; i have a question i think you can help me with. i think my 25 hp briggs and straton is leaking oil at the part where you said to clean well and sand paper it where it's taken apart. that whole surface. is that something you might have seen before i really need some help if you don't mind.
Don’t forget..!!!…. there is a short oil-pump drive-shaft that sits between the cam and the oil pump!…. Get it out of the sump before you reinstall the bottom sump-cover….then after installing the sump cover (oil pan)…. slip the short drive-shaft back into engagement with the cam-shaft keyed-end…. and reinstall your oil pump so that it is driven by the cam!
this engine doesn't have an oil pump. Note lack of oil filter and access cover on the sump cover. But for those that do there are a couple extra steps. This guy does a good job of explaining those steps. ua-cam.com/video/dWHPHGZAvj4/v-deo.html
Question: got a B&S 344cc engine on my craftsman 33” mower. Pull start on top removed. If I manually rotate the fly wheel it gets VERY hard to turn at one point. But it eventually gives and becomes easy again....until I reach that point in the cycle again. What is wrong?
If you have a oil filter on your motor, make sure you get the right cam. With oil filter,the camshaft will have a slot on the end. The one without oil filter,the camshaft will not have a slot. And as far as removing the pulley off the crankshaft? You may come across a stuck pulley. Then you have too heat the crankshaft.....Good luck.
On my MTD push mower, the starter motor won't turn with spark plug inserted. As soon as I remove it, it turns freely. What can cause that? I've removed the spark plug and pump out oil out of cylinder and piston wall. Have no idea what else to do.
Briggs had a good patented compression release cast into cam lobe,then they went to this junk compresson realease! The damn thing will just break again !
Anybody know if and where you can find a cam with larger lobes for a briggs and stratton 14.5 i/c quiet, possibly valve springs too and maybe a lighter flywheel?
Some poor sucker is going to watch this video and follow your instructions right down to tightening the sump bolts. Then when they go to put the pushrods back in they're gonna call you every name they can think of in the book! LMAO
Finally! I found a video that will help me with this job. Clear, concise, great tips...couldn't have hoped for better instruction. Thanks.
Excellent video. Right to the point with zero fluff. Perfect!
Its horrible, he keeps going back and forth between the parts. Have no idea what the part is called that broke. wtf
Thank you for the video. Superb narration, amazing audio and, wonderful camerawork. I was able to follow along and keep up with you throughout the duration of your presentation.
Well Mick isn't as good as Buggs Bunny and Daffy Duck yet but he might catch up if he tries.

How did it go? About to take this on myself
I always wanted to know what a CamShaft looked like ) thanks @MickMac72
Well there ya go! ; D
No clue who you are but I just did a cam job on mine and this helped tremendously. My first cam ever: thank you
Nice job! Easy to follow..
Great video. Thank you for posting it.

Excellent! Thank you very much.
One question if the dots don't line up what do u do in details please so they line up thank you
Great Job!!! Where can I find the replacement? Whats its name?
Where are the cam followers when you were putting in the new camshaft?

You do realize this is an issue with briggs and Stratton? The compression release breaks off and then the engine cranks hard.
2 years later and they are still junk. 41 hours on mine and I have almost $200 on parts to put it back together. JUNK!
If you use the mower intermittently , just take off the air filter , cover the pipe completely to cut off the air , get it spinning , pull your hand off & it will fire right up !! Been doing this for years on a 19hp Gold Series engine !!
You still have broken pieces in your sump.
Thank you for excellent help!
just what i needed to see......thankyou
Great video
What size crank shaft outer diameter does a 25 horse Briggs and Stratton have
This is exactly what happened to mine, I couldnt figure out where that broken part came from but my govenor gear was broke as well.
Craig did you get this repair done? I'm thinking I got broken cam or governed in a Murray 450 series engine. It starts but something is grinding
@@jesusdrummer21 yeah I did, it's actually a simple fix once you take the motor out, use a magnet to take the metal out. An make sure you get the right governor an new seal an gasket
Where's the lifters??

Don't for forget to put the tappets and pushrods back in :)
I believe it can be 280 out.. the crank turns 2 time to the cam, doesn't it?
Thank great video it help me thank you
But why do they fail? How can it be prevented?

Same issue at 41 hours. The compression release widget on the camshaft came off and broke the camshaft, crankshaft gears in mine. JUNK motors.
i thought the compression release is on the exhaust cam lobe or have I missed something?
What position is the piston in . Tdc
So if the valves move properly does that indicate the cam shaft is good?
Mick have you ever had the timing gear spin on the crank? I took off the oil sump cover to watch the crank as i rotated it, and as the timing mark gets to where it should be the piston is down about an inch..any ideas will be greatly appreciated! Thanks!

What are the specs for the valve lash adjustment ?
I have learned from this video
Does it matter about the cut in the cam shaft.
what is the part number
Question, can turn motor forward or backwards about 360 degrees and stops same place, any ideal what problem may be?
Sorry missed your comment . I presume you got it sorted?
Very Informative - Thanks -

Broken compression release lever. Replace cam.

And as far as removing the pulley off the crankshaft? You may come across a stuck pulley. Then you have too heat the crankshaft.....Good luck.
Well I saw that you didn’t clean everything out, when you put in the shaft there was a piece of spring laying in there.
Do you use gasket sealer when you put it back together
Some people put gasket maker on the surface the gasket will be placed on. But you don't necessarily have to put anything on the gasket.
On my MTD push mower, the starter motor won't turn with spark plug inserted. As soon as I remove it, it turns freely. What can cause that? I've removed the spark plug and pump out oil out of cylinder and piston wall. Have no idea what else to do.
check the flywheel key
It can be fitted 180⁰ out
Thanks mate
Me gustaría la traducción al castellano. Muchísimas gracias.
I have new Camshaft for my 31r907-0007-g1 not put in yet, what do I need to put on gasket

Briggs had a good patented compression release cast into cam lobe,then they went to this junk compresson realease! The damn thing will just break again !
Probably should install the push rod tappets first.
Anybody know if and where you can find a cam with larger lobes for a briggs and stratton 14.5 i/c quiet, possibly valve springs too and maybe a lighter flywheel?
3 mins and the first part on the camshat is dohickey thing
I have a troy bilt 2020
17.5 engine
Some poor sucker is going to watch this video and follow your instructions right down to tightening the sump bolts. Then when they go to put the pushrods back in they're gonna call you every name they can think of in the book! LMAO
You need for check up for yourself lossing ur breath
LMAO Yea ok clueless...
Briggs n Stratton Engines are junk, Ever since the over head Valves come out!!!
