Replace Seal on Blakeslee Mixer
I fixed up an old commercial Blakeslee mixer, but there is a slow drip of oil from around the mixing shaft. I am trying to replace the oil seal but I have no experience. For starters, would a replacement oil seal be available for my mixer? If so, how do you remove an oil seal? Which way is it removed, and does the metal part on the outside come off or not?

Do you have model and serial number? without knowing which unit you are working on it’s going to be a guess when providing a part number.
Here is a breakdown of the f-30

A neoprene lip seal is fused rubber onto a metal shaped ring. The lip side goes to the liquid your trying to prevent from leaking. They are a press fit to the housing.
With a Blakeslee, They have two that are important. One on the main shaft from the transmission, and the other on the planetary shaft for the mixing attachments. If the main shaft leaks, it will overfill the planetary causing weepage around the sides as well as the mixer shaft.
Over time, seals harden, and the shaft area that the seal rides on can wear and get a groove. Sleeve bearings can also get loose allowing the shaft to go off center. Measures to correct that can be to shim the seal wear area at a different surface or sleeve the shaft for a different seal.
They do require a installing tool. Flat face the diameter of the OD with a handle more that the width of your hand and a striking surface is a field version. I’ve used sockets and extensions in the past.
