I am in process doing the same repair on a recently purchased mower. Your video was very helpful. I placed my first order from Proparts, and the quality is excellent. Thanks for your time in sharing with us! David
You the Mando! Thanks for helping me completely give up on my tractor, appreciate it, high five!
Good to see your doing well Mando. They keeping you busy down there. Good video on that camshaft replacement. 🔧👍
GOOD VIDEO....RETIRED AFTER 50 YEARS......JUST REPAIR IN MY OWN GARAGE NOW FOR FRIENDS. THERE IS NO END TO BEING BUSY IN THE LAWN AND GARDEN EQUIPMENT BUSINESS. YOU HAVE AN EXCELLENT ATTITUDE FOR IT.
I really appreciate the Howard means a lot bud
All I can say is TYVM. Very good job explaining thorough breakdown on labor time and parts definitely got my subscription and alike first time here but I'm sure I'll be back God bless
I followed the video and repaired it quick as a wink. Thanks Mando.
No problem bud
Great vid thanks 🙏
Mando thank you for the video. Think mine needs replaced on my 18.5 hp Briggs Intek . About time they redesign the compression release
Nice to see one of your videos again Mando! Some parts you just have to use OEM , because tha aftermarket will bite you sooner or later. Good to see your very busy and goodluck bro! 👍💲💰🇺🇸 Roger
A trick so you don’t spray your engine with that tack spray is to simply lay the gasket onto cardboard and spray it the put it on the part.
Hey mando I appreciate the video, got it done in 3 hours after a few stops.
local shop said it'd be about the same cost as dropping in a new motor.. i said no thanks.
"Dot to dot! You cant mess that up!" Hold my beer.
GRATE‼️ ya✔️☝️
Who would’ve thought Drake was such a good mechanic.
Ha ha ha ha why does everyone think I look like Drake
You should have shown the two cams side by side to see what the counter wgt should look like and how it operates.
Is there no mod like putting a stronger starter on these engines and take the decompression off and leave it that way? All we want is to crank the engine.
If Your engine was running when You broke it down- avoid any confusion, Mark the cam and crank to Your satisfaction with a Punch- two dots on either gear or one dot on the other. Simple is what I am--Nothing simple ever works for me-- Good video .
You don't have to punch it because the timing marks are already there , just line it up !!
Excellent. That was my problem to the tee. Very very helpful. Thanks
How long do you think it would be till you have to replace the camshaft and relief mechanism again? I live in central Florida and would be mowing 1/4 acre every week possibly in the summer. Winter time not often if ever.
Why not put the spray tack on the gasket and not the cover? I've always put the gasket on a piece of cardboard to apply and then put it on either the cover.
Hola desde España, gracias por el vídeo. Las poleas de debajo el tornillo q lleva es rosca a izquierda o derecha? Gracias y muy buen video
No hay problema mi hermano
It’s a miracle! You’re recording like a youtuber! No more vertical camera frames! Hope you’re well bro!
lol thanks bro
I would not buy the aftermarket cams but I would install them but I would not redo it if bad unless I was paid
I have watched a bunch of these videos on how to replace the cam with the compression release on them, but my question is, are the new replacement release pins built stronger (thicker) so they won't break as easy?
I doubt it. Some people start it by blocking the air intake with their hand after turning the engine just a little bit past the compression stroke. Get it spinning with the intake blocked then take your hand off & it usually starts. The broken parts usually sit on the bottom of the engine.
Hey which direction does the bolt turn to take the pulley off the end of the motor shaft. Thanks jack
Usually left so upwards if the engine is off the mower frame
I agree, those $29 dollar "kits" that Amazon has are junk. I could probably snap the weight off this one by hand without too much effort.
And don't get me started on that wadded up gasket...
My original cam (17.5 hp Intek) was broken just like in this video, so I slapped it in anyways. Set the intake lash to .003 and the exhaust to .005, new battery, still too hard for the starter to spin it fast enough to fire up. I can see the intake valve do a little extra bump on the compression stroke, but Im guessing it isnt opening enough.
Got another 18.5 hp intek laying around with a (i think) a dropped valve seat. About to Frankenstein these two together if the bottom end is still ok. Tryin to make a half-assed race mower here!
Same problem here.
@@andrewaliotta5033 so far the cam I bought is holding up. What I finally found out woth mine was the head was so warped it was never gonna seal. Came to that conclusion after putting it back together (with the new cam, and a new head gasket) had to use a battery jumper set to 175 amps to get it to crank over, started up and it had oil coming out of the breather filling the intake, oil filling up the fuel pump, and the dip stick about blew off when i unscrewed. Smoked like hell after a reving it up too.
I got a real flat surface (well, I used a cinder block) stuck 120 grit sand paper to it with spray adhesive, and just worked the surface of the head back and fourth for like an hour until it was flat again. Wa la. Cranks over and doesn't puke oil anymore.
My guess is the warped head wasn't letting the gasket seal, so cylinder compression was entering the crank case, so much, that it was basically fighting against itself to run.
@@dogsandwich77 that's crazy! Thanks for getting back to me with that update. I'll probably hit it with some sand paper. I also see oil leaking from the oil pump plate. So I might need to get another one of those. Total disaster.
@@andrewaliotta5033 when they work, they work good. Overheat it once, and they're doomed. At least they're cheep enough to fix tho.
I have three of these engines. A 31P777, a 31G777, and a 31R977. They're all the same, all have or had the same problems. Thankfully there's enough info out there to fix them.
I still love my briggs flatheads more tho. I got 4 different ones that have all outlived they're means and are still going .
@@andrewaliotta5033 also, you can find those fuel pumps at Napa sometimes. But If the diaphragm on yours still holds pressure, it should fine.
Do you have the link for the kit? Trying to by right now
Pro parts direct part number 84005207 camshaft, 697110 crankshaft gasket , 795387 oil seal
do you see repeated problems with the mower once this is replaced?
Only once that’s only when I used a Amazon camshaft
NICEEEEEEE VIDEO!!!! One question, why did you take off that oil pump cover? Seems like you slid a metal piece down in there. What was that???? I know you probably have no idea what the hell I'm talking about lol But it was at 15:56 you said you forgot to take that little cover off and then proceeded to slide that little metal piece I'm guessing in the oil pump? Just wanted to know what that was........Man thank you so much for making this video!!! Oh and one dude said those have to be torqued to 180 inch foot pounds....
Are you taking about the oil pump
@@118armando ohhhhhhh is that what that was??? LoL yes sir, the oil pump, did you replace it? Was there something wrong with it?
Sometimes when you put in the cover back on that pin is not lined up for the oil pump so it’s easier taking it out
I got this problem and was wondering if I can just use a wimmer compression release spark plug adapter and bypass this stupid camshaft compression release bull shit...
Quick question..... A tech diagnosed the same problem on my tractor. How much will be a fair price for this job?
All together it’s a 3 hr job from diagnosing to riding and testing I charge customer I think 230
Will these parts fit in the 17.5 Briggs I have the same problem?
Yeah 😊
i've had the experience where the cam is not broken, but acts like it is. I opened it up, and everything was intact. the cam had everything where it was supposed to be. So what was the problem, I put another cam in, but wondering what makes a xcam bnot work right if everything is intact on the cam.?
Broken compression release arm on the cam shaft. That is the pieces he's taking out of the pan with the magnet in this video, the little arm he showed is the release.
Valve adjustment was off.
I think all the parts are made the same if the Briggs part was so good it shouldn't have broke so a cheap brand part will work if it breaks ill be taking it apart a few more times
This was the exact problem with my mower. I replaced the broken camshaft with the new compression release, but 8m still having compression lock issues. I've tried adjusting the rocker gaps to spec as well. I've about had it with this motor
Did you ever figure out what it was? Sounds like the problem I'm having.
@@tylerdavis7785 nope. Sending it to a mechanic next week.
I bet you it's (or was) the head gasket, or a the head itself is warped.
I put one in my piece of crap Briggs & Stratton and when I turn over by hand and it gets to the compression release it makes a ping sound. Is that normal?
Very nice video question, do you have to redo the valves readjust them? I'm not positive. I've seen videos that people don't and people do
Yes the first thing I do before I remove the engine is Loosen the valves because trying to install the camshaft without doing that makes it difficult
I replaced three camshafts with the pressure release valve made on it. The last camshaft was an original B&S replacement part. All of them broke. I gave up and replaced the motor , with a warranty. I've got my fingers x for better luck. Do not buy these crappy engines! This by the way was the same motor!
I have been very lucky
@@118armando or better at repairing than myself 😊

Where in Fl are you located?
Vero Beach FL
The very WORST part of the job is removing the old gasket. Engine body is 16:25 aluminium so you have to be very careful with your scraper. Painstaking work.
An alternative if you don't want to take the engine off, and you have the tools. ruclips.net/video/hFaxIl_rDg4/видео.html
How much would a shop charge to do this repair?
135.00 plus parts
@@philliphall5198 $230 plus parts
What hp was this engine ?
20hp
I still see crap down inside the engine block you should have sprayed it out better
why cant someone make a high torque starter for the briggs, then you wouldn't need compression release. auto and truck motors dont use releases.
That would work so much better
oem parts fail to the new motors are junk honda is the best
I wish U was a little more in-depth
So far all ohv moters are junk
Dont waste your time replacing these things....they dont last long and arent worth the money....if you are having issues with yours not starting just manually turn engine to just over top dead center...squirt some starting fluid into carb....put your filter back etc and it will start right up....Its a shame they put these pathetic things on lawn mowers...
Mine doesn't wanna do a full turn over by the key because its broke its been broke like that sense i bought it used. Im gonna have to waste some time on it i have a ton of other riders to work on now i cant those until i fix that one first because i use it the most
Turning by hand how you said worked for 2 years but it ain't gonna work that way this year even with a new battery it trys to spin then stops
I've put off on fixing it for so long cause i have been helping everyone else and working on their equipment
@@Mike-su8si roll it over by hand right past compression stroke , take off the filter , block the air pipe completely off with your hand or rag etc. , crank it over to spin it up , uncover the intake pipe & it'll fire right up !! 🤨👌
And lower the throttle...if it takes big gulps of air...it will not turn over..after it starts Rev it UP.
Waste of time, bad music.
Good advice magicone9327
