Our dealer here says if they find a leaky gearbox they drain out the oil and fill them with corn head grease.That's the way the new one's come from the factory.Did it on my 9400,no more leaks. Tom

Yes, getting the belt loose and removing the pulley is a start, there is the hub the pulley attaches to that would have to be removed also. There is a bolt_washer setup that holds the gearcase on the shaft - many times on pre 10 series combines the bolt breaks off and allows gearcase to wear on crankshaft and at that point you might as well update crank. I believe you also have to remove rod that applies tension to the crank_shoe_supply auger belt. Some times the gearcase pulls by hand and some pt oil and other times it has to be pulled - JD service has a special tool to do this. As for seals if you have the gearcase off, replace all 3, also you have to split the gearcse to get to the seal that is right by the side sheet on the crank drive gear because the case is chamfered so the seal can't pop out easily. Check the brgs. and case closely to make sure none have spun into aluminum casing. And yes, if you want you can refill the case w_ 1 tube CH grease - parts can order the plugs needed or go back to oil. Any other questions reply back, Gg

you get the parts to convert it over from your deere dealer and you have to use a special puller from your dealer to get it off

Any idea what the part n is for this. local Deere dealer doesn't know but said they will try to find out. How complex is this conversionIJ Seems like all you would need is a grease zerk and a bushing to go in where the oil fill tube went in.

Have your parts guys look at the parts breakdown for a 50 series walker machine gearbox which will show what plug and zerk to order. It takes 1 full tube of corn head grease to fill the gearcase. The puller is a special service tool thru deere servicegard, Ask your service dept. if you can borrow theirs if you cant get it off with a little lube and a bar or two. The tool n is JDG643A and costs $336.00. Gg

Thanks for all the info. Got the parts ordered. By the way, the JD online parts catalog is very helpfull although a little hard to navigate sometimes. If anyone has never used it, give it a try.
