First let me say, my wife did some "cleaning" and now my IT manual is missing. Okay, to the problem. I have 1941 Farmall A. And thanks to all you great people on this forum, I"ve learned a lot. My front seal is leaking a little and I want to repair it. Is this a tap in seal like you find where the torque converter goes into an automatic trans, or is it half seals or what? Is a jaw puller the best way to remove the crank pulley. I"m sure once I get the front apart it will be easy to understand how to do it. Just wondering about any possible surprises. Thanks.

Napa sould have the new seal and you install it the timing gear cover. You need to look at the hub surface on your pulley for a worn groove from the old seal. You may need a speedi-sleeve to cover that area. You should should use a split bearing separator behind the pulley so you don't damage the pulley. Some of those pulleys are hard to remove like a press fit. You may need a puller like BigDog made for his Cub using a bottle jack or hydraulic ram. Hal

Yes the timing cover has to be removed as the seal goes in from the back. Like other post said you will need a puller to remove pulley and then some way to press it back. You also need to remove the steering sector as the pulley wont clear it. Thats why you mite want to get a speedy sleeve so the new seal has a good surface to seat.

Glenster is correct! The timing cover stays put the seal goes in from the front. The old seal can be removed with a slide hammer and flat hook, or sheet metal screws driven a little ways into the seal metal. Work it out from each side, not from one side only.
The speedy sleeve is a thin metal ring that slides onto the pully machined surface to cover the groove made by the old seal. NAPA, and places like Motion Industries have them to fit, Take the pulley and old seal.
It is also possible to purchase a seal that has a different thickness or lip location such that the seal rides in a different location on the pulley shank. Some of the pulleys come off with more than 4000 pounds of force. A stout splitter, or "U" placed behind the pulley is mandatory or the pulley will break. The shaft is a press fit, and can be polished some befor replacement to allow an easier install, but still a real press fit. not hand loose. It is retained by this friction. Jim

I've only bought one sleeve (so far). I found a bunch of them on eBay and bought it there. If I remember correctly, the spelling is "speedi-sleeve" or "speedi sleeve." That may help a bit if you do a search for them.
I installed the sleeve and a new seal on my 350U's PTO shaft. It hasn't leaked even a drop of 10W oil in a year and a half.
Check the archives for a way to modify a piece of PVC pipe to drive sleeves onto shafts farther than an inch or so.
