Does anyone know where I might purchase a front crankshaft seal for a 1942 Farmall A? Secondly, what is involved in replacing it?
Thanks.

I just did my 46 A because I'm completely rebuilding it. This is certainly an involved job. You have to remove the radiator, governor housing and the front bolster and axle assembly. This is just so you can get to the timing gear cover so it can be removed. I had a devil of a time removing my pulley and actually broke it because I was trying to get by without purchasing the right tools. I had to buy a large OTC pulley puller and a large OTC 2-jaw puller to get the orignial pulley off since none of the stores had any for rent. The replacement pulley went on really easy because my crankshaft is threaded and I was able to use a bolt and fender washers to pull it back on. Be sure to leave the bolts on the timing gear cover loose so that the puller can seat the new seal squarely, then finishing tightening the bolts after the pulley is completely in place. Get a copy of the I&T shop manual. It has a picture of the puller set-up. I got my oil seals from the CaseIH dealer but NAPA also has them because they are made by Chicago Rawhide. You might consider getting a complete engine seal/gasket kit. They are only about $50 and contain everything you'll ever need.

is the procedure the same for the front seal on a farmall 100? or do you have to take the front axle off? thanks.

Larry, Look in the archives as there have been a lot of postings and answers to this. As Steve said, bottom line it is not an easy task especially removing the crankshaft pulley as they are usually pressed on and you need a puller with a bearing separator to pull on the pulley so you don't break it.

Finally I cna help someone. You need to remove the front pulley, and remove the cover. It is a pressed fit into that cover. I had my radiator off when I replaced mine, and had to remove the front bolster, and the hole big radiator support on my BN. On an A, I can't tell you if it can be done wihtout removing it, but my guess is that it can't, and even if it could, the risk to your radiator is too great. My pully pulled right off by hand, but I have heard of others who needed a puller.

Bottom line....I think you are looking at a big job.

Good Luck Steve

You can get one from your local case IH dealer, or take the part number to your local NAPA and they can cross it to a National or CR seal Number and get you one.
