Jeff, your video was very useful, my 13-year-old B&S 26hp engine is suddenly leaking a lot of oil. I cleaned the engine up enough to see that the sump pan gasket was the problem. I put a wrench on the bolts holding the sump to the block and I found that they had all worked themselves loose. I snugged them up and ran the mower for a bit and no more leaks. Time will tell, thanks again.

This is a great video. No loud music, just everyday logical mechanical work. Good tips, reference to B&S manual and torque info. I think I would change out the oil pump “O” ring, filter and any other parts that might have been practical while it was open as well. Great job though.

Dude, you probably saved me at least $500 with this video. A few years back, I decided that I could do these kinds of repair, but wasn’t comfortable. This video not only exactly diagnosed my problem with my lawn tractor engine, it also gave me the confidence to do this myself. Thank you!

@jeffslawnmowerrepairandservice 3 года назад

@stevennoxon337 3 года назад

Last weekend, oil was literally pouring out of my 2009 Husqvarna tractor with a bigger but almost exactly the same B&S engine. Bought the whole gasket kit, figuring why not replace everything I can while I have the motor off. Started up like a champ today and not a single drop of oil is leaking. Thanks again for a fantastic, comprehensive and really well-done video. Showing even your “errors” was extremely helpful. Wish I could link the video of my tractor firing up and running like a dream for you!

@tommagiera4784 Год назад

A truly great instructional video. I have to perform this repair and you have taken all the guessing out of the job. One thing I always do before taking anything apart is to hot pressure wash everything I can to make the work easier. Thanks for the help.

@jazpanoz4996 4 года назад

Take spark plug out so you can turn crank without compression to drop the bottom pan onto motor, a ton easier & less likely to fold main seal over itself,😉 great vid 👍

@raycman 4 года назад

Thank you for your video. I used it last week to replace the oil pan gasket and shaft seal on my mower. It was very helpful. Tips I would add for others using the video for reference would be to consider also changing the governor seal and the oil pump o-ring while you've got the pan off. The parts are cheap enough...

@johannesels5288 4 года назад

Should be called "Breaks and Crappen"! Maybe they were a decent motor back in the day.. I have a ride on with 16hp Vanguard and less than 300hrs on it and so far one head gasket went at 106hrs and now I diagnosed a leaking sump gasket. There is a 100mm section where the oil is pissing from where the gasket is not even visible, just air gap and oil bubbling out. The reason they have to update these parts is cos they are shit to begin with. 1300hrs on my Honda powered mower and nothing but general service and valve adjustment. Thanks for the good video mate, looks like I'll need it tomorrow.

@BRANTCNC 4 года назад

Thanks for the great video. Just repaired my Craftsman fs5500. Wouldn't have been able to do it without your help.

@mrmhandley1 2 года назад

I have the same problem, and thought it was most likely the crankshaft seal, after power washing all the dirt and oil off and running it a few minutes. I was thinking that top pulley spinning was what was throwing the oil everywhere. I can see clearly from your video that top drive pulley was dry on yours. I'm about to tackle this and was hoping to just get away with replacing the seal without splitting the bottom cover off. I now expect mine is leaking from that gasket too. So thanks very much this helps me so much to know what to look out for before tearing it apart.

Same leak, same place in a newer 24hp. Seems to be a common fault with these motors. Mechanic friend did one motor 3 times and the same problem with a blown gasket each time. B and S told him the fourth time to permatex it. After the permatex, no more leaking.

@donens9310 Год назад

Recently had a Vanguard V-Twin 35HP horizontal leaking oil at crankcase cover and PTO oil seal. This is on an new grain auger. After receiving replacement parts, removed the crankcase cover and found there was no gasket, just RTV silicone. The cover showed that the silicone had not stuck at the bottom and several other points of the cover, thus the leak. I assume, that the mating surfaces had oil residue so the silicone couldn't stick. The old oil seal showed evidence that it had flipped in two spots, thus another oil leak. This is a brand new engine, less than 10 hours, so right from factory. Ever seen NO gasket on the crankcase by Vanguard V-Twin?

@jeffslawnmowerrepairandservice Год назад

yikes, That sounds not good. New engines usually have less than 1 hour run time. I have never seen that. The seal was flipped/no gasket... so sounds like someone was messing with it.

@docroot462 2 года назад

Could I send you 2 pics. I followed this video to remove the engine on my craftsman gt6000 26hp and on the oil pan sump assembly I found a screw in plug on the side just rear of the oil filter that was loose. I tightened it back up snug. Upon examining the cast aluminum assembly I saw a spiderwebbed looking cracking cluster but can’t tell if it was also leaking and is worth replacing or a normal thing?? Your videos are spot on and extremely helpful!

@jeffslawnmowerrepairandservice 2 года назад

probably just casting marks.

@roberts1159 2 года назад

Appreciate you taking the time to do this video. Helped me a lot performing this same job on my 2003 Briggs 21 hp v-twin. After reinstalling the engine and starting white smoke pours out of the muffler area. Oil level is correct and at the full line. Wondering if perhaps oil somehow drained into the top of the engine and then collected inside the muffler upon initial startup ? Thought’s on what the issue might be ?

@jeffslawnmowerrepairandservice 2 года назад

that could be the case. If so, it will take awhile to burn out.

@jamesbrannon9594 2 года назад

Run it until it stops smoking could be oil in the muffler or oil leaks from the past that need to be fixed

@jeffslawnmowerrepairandservice 3 года назад

@philliphall5198 Год назад

Change the governor seal also to be safe, seen a lot of them leaking and they said sump gasket

@donf3739 Год назад

I would put the seal in last, tapping it in with a piece of plastic or metal pipe. That makes it easier to put over the shaft without flipping inside-out. Also, seals usually go in easily enough, and stay in more securely, without lubricating the outside of them. It looked like this engine has a ledge in the bottom of where the seal goes, so you just tap the seal against that. Otherwise, yes, just below flush. Too far and you plug that little drain hole.

@skirtdevil 5 лет назад

Good video!!!!!!!!!!!!!

@soyomofo3162 2 года назад

Why not mark the cables with colored electrical tape wrapped around the cable and taping over the screw hole? I also put bolts and nuts back in holes to not lose or mix/match them.

@jeffslawnmowerrepairandservice 2 года назад

good tips!

@mrfudgierubber 4 года назад

I have just this job and in my ignorance drove the seal all the way home! However I notice the hole would only be covered half way by the seal. OK do you think? Thanks for your vids, very detailed.

Fix it right! I used to always buy 2 seals until I got better at putting them in. I have messed up a few...

@jackendbox1 2 года назад

Is it okay to use Permatex on the gasket? I was surprised you didn't use any. Going through all that work I would want to take every precaution I could so it wouldn't leak.

@jeffslawnmowerrepairandservice 2 года назад

If you install things correctly and clean off the old gasket no permatex is recommended or needed.

Hi there, i have recently purchased a new Ferris 400s zero turn, it has a briggs 23hp commercial. I noticed when i received it from the dealer there seemed to be oil spray everywhere primarily all over the frame and deck area. I contacted the dealer and they said it comes shiped like that for better protection. So I thoroughly wiped down all areas. I then noticed after its first and again on the second use more oil spray over some areas but nowhere as bad as it was. What are your thoughts on this? Could it just be some leftover protection oil i might have missed or could it be something else going on? I will also mention I can't see any signs of oil running down sump or drive wheel housings. Cheers.

check the bottom crank shaft seal for leaks and all around the sump gasket

@deant6627 5 лет назад

@@jeffslawnmowerrepairandservice thanks for the reply, it seems to of stopped now, pretty sure it was leftover oil seeping out of the joints of the frame where some things get bolted on. Due to the air pressure from the deck and the blower housing was drawing it out and moving it around.
