Puller for Stihl 028/038 Crank Seals ?

[blueberrymuzik]

I recently acquired an 028 Super and an 038 Magnum that I'm working to get back into running condition. In addition to many other things that I have replaced, or am in the process of replacing, both saws need the crank seals replaced. I have already changed out the seals on the clutch sides, but am at a loss as to how to pull the flywheel seal. It is just too small for any puller I currently own. I'm curious as to how everyone pulls this seal without investing in a special puller from Stihl.

I have used the lisle puller without any problems but now I have the Stihl puller. In my opinion it is worth the investment.

Actually I own a whole mess of pullers, and to be honest, either a modified small flat tipped screwdriver, or a drywall screw works just as well.

I like the drywall screw application

Drywall Screw?

Sounds like a clever idea. How do you go about it?

A small screwdriver with a 90 degree bend on its end works as well and is a lot faster for removing all chainsaw seals, especially the flywheel side seals on the 026 Stihls. I have the other seal pullers but reach for my trusty hand made screwdriver puller most of the time.

I'm sure there are other methods, but here's my way:

Very sharp, brand new pointy drywall screw, put point on metal part of seal, tap with a small hammer to make a dent in the seal, thread screw into seal very slowly until you feel it get a good bite, get some side cutters and grab the screw and use them as a lever to pry out the seal. You can use the end of the crankshaft or part of the case as a fulcrum. Seals come right out.

MAKE SURE that you do NOT get the screw into the case bore or scratch the crankshaft. That's why I like to tap the screw to make a small dent in the metal part of the seal. The screw can't walk around when you start threading it in. Also, don't thread it in too far or you get into the bearing cage.

By far the one of the easiest ways to pull a seal. The Stihl tool is easier but I can buy drywall screws for many years for the price on one of those.

Drywall Screw

Sounds like it is definitely worth a try. I appreciate the cautionary info also.

I tried the drywall screw idea today on the 038 Magnum and it worked like a dream. Many thanks!

I made a tool out of a piece of 1/8" stainless steel flat stock that works better than any other pullers or improvised methods. I gave the details to another member here, and hopefully he will make it available to everyone.
