Awesome vid! I had the same starting Cam lifter mech failure and your vid walked me thru the entire repair process! Thank you!!!

Great video, I’m waiting on the parts to do this exact job. 7:58 you didn’t do anything wrong it worked out great for you, great job. Many times it’s not that easy and turning the crank a bit, will help the gears and governer seat with out too much force.

I had to do this repair just now and your video helped. Thanks.

Did mine today. Thanks for the vid. Helped a lot.

I am having the same issue and having to replace the camshaft. Your video is extremely helpful. And special thanks for providing the torque specs. The only thing I would recommend to everyone out there (like myself) that is gun shy to turning a wrench, be careful when removing the original camshaft. The taps and possibly the push rods can come loose. Make certain the push rods are seated against the rocker arms correctly when you reinstall the new camshaft. I found this out the hard way unfortunately. But once I got the new camshaft in place, it held the taps/push rods in place (seating correctly against the rocker arms). I pray that the new camshaft will last me another 3-4 yrs. The compression release section looks to be cheaply engineered. Shame on you Briggs and Stratton !

Thank you so much for this video and putting the torque for the sump 220# in the description, 90# on the oil pump cover for easy reference

Great video and thanks for sharing. I replaced my crankshaft and adjusted my valves using your videos.

Love the detail

For future reference, it REALLY helps to pull the rocker cover and remove the push rods. The old cam comes out easier, and the new one goes in without having to fight the push rods and lifters. Also, it's probably a good idea to readjust the valve clearances anyway with the new lifters in. Thanks for the great video!

I am not a mechanic at all. But this video has me seriously contemplating attempting this repair myself. I would love to see a video of the compression valve releasing a little bit of the exhaust when turned by hand.

Great job thanks for posting this. I agree with the quality control issue and great engineering.

Blueoyster5,,,,,,Was your mower hard to crank,,,,when the deprression spring broke?,,,,Thanks

Great awesome job dude

Thank you for the video

Bought a rider with same engine blown rod. Great video got mine all apart waiting for parts. What is torque spec for cover.

I have a quick question, while doing this repair, I also changed the oil seal in the sump cover and noticed there was a sort of O-ring in there also, it seems to be a sort of a "spring" like ring, not made of rubber. one was not included with the new seal P/N 690589 (#943 on the parts drawings on line) is this thing part of the original seal that came off or is it not needed? i dint see it anywhere listed on any of the drawings.

I don't see an oil pump shaft. I didn't notice anything fall out and I didn't take one out and you didn't mention or show one in the video. How is the camshaft turning the oilpump? I have a new oil pump with all the parts on order.

Great vid.Was wondering if you could answer a question?Had a friend helping me because the same thing happened to my engine.Anyway,he removed the camshaft before I had the timing marks lined up! Will this be an issue if I spin the crank to allow for the cam to line up?Also my crank gear has a divot mark and what appears to be a small cutout about 180 out.Do I use the divot mark to time?Thanks.

Just got done replacing the cam.Used the marks we talked about and she fired right up!Thank you.Now the problem I have is it was spitting oil out of the muffler.Could it be because I drained all the oil and refilled it and it pushed it into the head when pressure was built at first?Any thoughts?Thanks for the help.Its awesome to have people like you.Keep up the good work.

This video helped me replace the original camshaft when the compression release on my lawn tractor failed about 2 years ago. It has since failed again, with probably no more than 60 hours on the replacement cam. Unacceptable imo. Such a bad design. I'm going to repair it and sell the tractor and probably get an electric one.

That has to be the cleanest engine that's ever came off a mower, what do you do steam it after every use?

I have a problem when I align timing marks my rod cap hits my cam lobe?

Hello, Great video as I will be doing this very thing as soon as the parts arrive. Can you tell me what the torque is for the sump bolts please?

I tried adjusting valves on a briggs 331877 2371 G1 and it still wouldn't crank. How can you tell for sure that the compression release is broken before tear down?

Does anyone know the average cost to have this completed by a small engine shop? I've done enough troubleshooting to determine this is the problem with my tractor, but this is getting beyond what I have time to complete. I'm trying to gauge if it's worth my money to get it repaired or buy a new mower.

What date did you upload the Briggs camshaft repair engine startup?

It would be wise to change the crank seal since the sump is removed. Cheap insurance against a leak since it's all apart.

@Blueoyster5 ,I am currently working on my undergraduate final project. I would like to know if it is possible to get the design information of the camshaft gear in the video above and how ( in respect the addendum ,dedendum, PCD etc.). my research suggest a material that may likely fit in as a possible replacement for the nylon 66 made gear . I anticipate your reply soonest.

4 yrs later and I'm back again with the same issue. Ugh! Mower does not want to turn over and afraid its most likely the same problem. So, now deciding to whether spend $150 and replace this camshaft once again, or - throw the towel in, get a different mower (And not a Briggs Motor). At least I can say I squeezed out 9.5 yrs of mower life with one camshaft replacement. LOL

I just finished mine but after 1 complete turn it locks up, not sure what it could be?

Did you replace the tappets??

Where do i find the mark for timing

What is the torque for the casing cover bolts?

Damn, one of the oil pump cover screw doesn’t come off. Looks like it’s seized. I tried with WD40 with no luck. Any suggestion? Cheers

I let it run for a little and no more oil spitting out.And I didn't use a casket on the cover,just permatex.However I did see where oil was coming out.i also called b&s and they recommended that instead of a gasket. Because of the model date.I Also told them their products are shit!Do you think it would hurt to put a gasket on?Thanks again for all of your help.May God bless you sir.

What was the torque on the sump cover

How old was the motor when this happened? We just bought a poulan pro with a Briggs and Stratton intek 19 hp. Should I be concerned about this happening anytime soon?

How much does a mechanic charge for a Briggs and Stratton 17.5hp replacing cam shaft?

hi, can you put the link to where you get the parts you needed to replace. I need the same, but cant find it. Thx

Crank cover bolt torque?

Can I ask why you removed the oil pump cover?

Is this on a twin cylinder

Whats the tork rating

thank you you help me figure out what those broken parts was in mine just like yours that's all that broke

What is the torque specs please?

Same problem with mine

To prevent this in the future... NEVER run your Engine full RPM. I always run mine at 3rd and that is it. Surprisingly, all my stuff left over from my Gram-pa still working. Some are actually from the 70's!

I need caim shaft

I agree, poor design, most likely due to funding, I wish I would of researched a little better before buying. Great vid! Thanks

Dude..showing HOW to rake out and replace the cam is what people want to see,you buzzed right through that. And..you do NOT use grease on the cam,it will clog your oil pump,regular mower oil will do the job,and NO ,you DO worry about a little gasket sealer inside,it also will clog you oil pump. But hey,other than that,good video...lol

disapointing video
