    I have a used Freedom XT with a liquid cooled 26hp engine. I made an aluminum drip pan to slip under the machine and I notice it collecting oil from both sides of the back of the engine. I am having a hard time tracking down the source so I am wondering if there is a common leak similar to mine that you may know of. It's not the oil filter or valve covers...originating fromt he back somewhere. Any ideas???

    i used to have a 18hp kohler and it leaked oil from the rear main (crank) seal. i replaced it a couple times and the new seals would only last about 6mos. and start leaking again. i think it was due to a lot of hours on the engine and slop in the crank, so i finally replaced the engine. --Kevin--

    Rear main...great, need to do that one on my van too! How difficult was it to replace on your Kohler? I am a good auto mechanic but am new to small engines.

    it is easy once you remove the pulley (or coupler) from the crankshaft. i just used a screwdriver to pry out the old one and carefully tap the new one in with a small hammer, keep it even and don't tap to hard. also make absolute sure your new seal is correct before removing the old one because it will get destroyed. --Kevin--

    So is this an hours job or an all day occurrence? I have a service manual for my engine but it doesn't really cover repair...only reassembly.

    if yours is a pulley (with belts) you can probably do it in an hour or two. if it is a coupler it just depends on how long it takes get that off (i am not familiar with coupler set-ups). --Kevin--

    I have a Peak with a Kohler motor with 1400 hours. Mine started leaking about a month ago. Took it to a small engine repair shop that works on truckmounts and they said valve covers were cracked, causing the leak. NOT! It's the crankshaft seal. Don't look forward to that repair but it's gotta be done.

    Had the same thing happen to mine. About 1200 hours when it started. I also had a drip pan made for it, I just kept wiping it up, it was never a bunch at a time. Just check your oil everyday( like you should) It never hurt the machines performance. I sold it with 3000 hours on it.

    Drip pan? That's a good idea. How big is it and where does it go (other than under the drip)? I'm getting oil on everything as it is. Do I need to have a drip pan made or is there something I can buy?

    I had to have mine made for me...aluminum and 100 bucks but worth it. Mine is 22" X 36" and slides in and out and covers the whole underside of my machine so I can catch any new leaks. It's kinda like a drawer.

    There is a company called "blitz" who makes cheap ones that are sold at autozone or schucks but they are like 27" wide by 36" so were just too big for my application. These are only like 20 bucks though.

    Update: Cleaned everything off to verify its the back cover to the engine. I will still replace the rear main seal while I have it off. The pulleys threw me for a loop when trying to remove them but these awesome TMF guys gave me the solution!
