can i handle replacing lower kohler gasket

i have a gasket that blew out just behind the oil filter on my 27 command kohler

i have the motor out already. i dont really have a engine stand.

how hard is it to pull the bottom cover on the engine and replace this? looks like the whole bottom end of the engine needs to come off obviously.

Pull'n the cover isn't nothing, Put'n back on is another story......

Go here; http://www.kohlerengines.com/manuals/landing.htm and download the manual for your engine then follow the destructions.....

Replace the lower crank seal while your at it and don't forget to install the oil passage seal, Watch while sliding the cover back on and make sure the governor gear meshes with the cam. If it doesn't the governor gear can be damaged and the engine over-rev on first start......


Pssst..... My trade secrete is.....Spray paint the new gasket just before installing.

Hmm,

yeah maybe i'll just give it a ride down to the dealer. Shouldn't be more than an hour for him now that i have it out.


is this caused by overheating? does it build pressure in there? seems like it just blew out.


i need to get a different breather cap for my hydro tank. there was a decent amount of gunk in front of the motor.

on a everride

Crankshaft end play is factored without RTV on the gasket, Add RVT and end play changes...... Paint is sooo thin it doesn't change this and after the engine hits running temps a couple times it WILL seal better than any RTV on the market......

i think my engine decal is gone.

i dont exactly know what i have.

i'm guessing its a cv-740 but not sure.

i got it all apart and cleaned up and ready for the new seal and gasket.

any tricks on getting the cover back on? i can see its not going to go smoothly

Slide the pan on, With a flashlight and small long screw driver snake up into the gap and rotate the governor gear until it meshes with the cam gear.

Then use the palm of your hand to tap the pan down the rest of the way, Install the bolts and tighten;

Niiiice!

Yes, hard and brittle gaskets tend to be caused by overheating.

I have learned, clean the engine often with compressed air (a backpack blower works for me, or one of those air compressor nozzles) especially the fins and just keep it clean of dirt and debris.
