Pittman arm shaft seal question.

Bob's has them for a 37 through a 59 but I need one for my 35 forty series.He didn't know if it's the same.Does anyone know for sure or where I could get one? Thanks.

Any bearing supply business would be able to match the seal. It is nothing special

 

If you have a number or can measure the size McMaster-Carr might have one

The new Pitman shaft seal I got from Bob's is marked as National Seal #50151.  I measured the OD as approximately 1.56 inches (1 9/16").  The shaft on my '38 is just over 1 inch in diameter (~1.1").

Give Dave Tachney a call.   He might be knowledgeable on the '35' - 40 series  steering stuff.    It looks just like the '37 - 40' series steering stuff.   I'm not sure but my 35-50 series looked the same as my '37-40 series.   Buy one from Bob's and check it out.     Just be sure that Bob's will take it back if the shafts are not the same.   Is that pitman arm just worn and the seal  keeps the grease in the brass joint.     Push come to shove,  Imused to sell brass bearings and there are many sizes to replace the worn brass bearing.   The seal can be matched by measuring the shaft  O.D. that goes through the old shaft.    Any good industrial parts house that sells oil seals from Garlock, National and others to match.    If I have a problem, either I will change parts and use the '38-40' series steering stuff or just get a brass bearing that comes close and have your machinist make it just like the original bearing.   Buy a new oil seal that matches the same dimensions.   Those things are usually rebuildable by design.
