Any way to soak the gunk out of the main and pto clutch disks?

Kinda shame to buy a new disk set when the ones there are already new. Cause is oil seal leak. The disks are 256$ and 90$. Seperate rivet on kits are not available.

Thinking of soaking in acetone or solvent for a day then drying off in an oven at low heat.

Another question is that my manual says to install flywheel ring gear, heat gear to 500F before installing. Does anyone know why?

CRC Brakleen, available in spray cans at auto parts stores. Made for cleaning brakes, but clutches are the same material.
And it's non-flammable too.

The reason you heat the ring gear is to expand it. Remove the old ring gear, either heat it or take a chisel and spit it to get it off the flywheel. Then heat the new ring in oven or with a torch, be careful not to overheat it. It doesn't need to be red hot, overheating can take the temper out of the teeth. Once its heated to expansion, just install it on the flywheel and allow it to cool. It contract as it cools and make a very tight fit.

Clean organic clutch disc in parts cleaning solvent or can use acetone type paint thinner(be careful of sparks or flame). IF you have access to oil absorbant floor dry, put disc in it and let sit for at least 8-10 hours, if not let air dry for a day.. Then install, I know the books say not to but!, why not try to reuse.. As for heating the fly-wheel ring, that expands it so it will almost slip on over the flywheel, and when cool will stay in place.. Heat it evenly or you may risk removing some of the temper from the steel..
Have done both of these operations many times.. goog luck..

Yup, just contracts on flywheel, as to how well it works just wait till you try to get the old one off.

Soak them in a bucket of gas for a day or two. Did this on a 460 and haven't had any problems.

Hey BlueLight,

Be real careful drying something soaked in acetone or other volatile organics. Had a lady in a lab I was in pour abou 10mL of acetone into a hot flask to clean it and it vaporized instatly on contact with that hot surface, but luckily didn't ignite. Know a PhD here in our labs that had some clown leave etherised rats in his fridge. Being a standard fridge and not protected against volatiles, when the compressor kicked over one day it ignited the ether vapors, blew the door off the fridge, and knocked out several windows. Acetone and ether can both make some pretty impressive explosions, so if you use them or any other volatile organic please dry it away from sparks, flame, heat sources, etc. Vacuuming them into a wet vac, drying them with a conventional fan, putting them into a warm oven, etc. can easily set the stage for a bad fire or explosion. Be careful out there, and good luck with your project.

Darren

Actually, I think it might be worth a try to soak the oil out of the clutch discs, I guess it all depends on how willing you are to split the tractor the second time in case it doesn't work?

Your clutchs are trash, need new ones, the ring get needs to be heated to expand it so it will go over the flywheel.

You've got to split the tractor to fix the clutch and the oil leak. I tend to agree with Van that the clutches are likely scrap. If you are well equipped and very adept at splitting the machine you could give it a whirl to try to clean the disks. If it doesn't work, you know that tractor will fail on you right when you need it most or in mid winter if you have no heated work area. Tractor repairs tend to be labor intensiove so there are very few repairs where it really makes sense to scrimp on parts and parts aren't cheap but that's the way it is.

I did wash my bus clutch with degreaser, it was 3 years ago and it works better than ever. And my TD9 clutch, I cleaned it in a hot water soda wash machine. It�s also working great. /Dennis
