This all reads well but I have a question regarding the removal of the crank seal. Mine just does not want to budge - any tips?

different strokes

the more experienced you are at placing all types of seals the less inclined you'll be to spend $

I completely understand the occasional wrench buying this tool and piece of mind.

And don't use assembly lube for placing the 915 input shaft seal in place. Use a thin dino oil, 20w, if possible.

I followed the method shown on pg 34 of Wayne's 101 Projects book (with pics). Take a screwdriver and push it if you can (punch it lightly if you can't) into the seal angled towards the outside edge of the seal being very careful not to scratch the surfaces of the crank or case. You are attempting to catch the metal skeleton of the seal....then using another screwdriver rather than the crank surface, pry it out. You will have to do this procecure in several locations to get it out once it breaks loose. The seal will deform as you do this. This method worked like a charm for me. Good luck.

Nice tool, but IMO it's almost impossible to damage that seal while installing it, using any number of methods.

OR........ you can try Fred Cook's method which looks like it will work as well as the P234 requiring tightening three nuts to press in vs one. Nice work Fred!

I've had some success fabricating home made tools myself with PVC....:D

of course the Porsche gigabuck tool is nice, I'm thinking a shade tree mechanic version could do close to the same job:

1 - a way to tie threaded rod to the crank and keep held and centered
2 - hoop (plastic pipe part?) of proper diameter, fits rim of seal near the outside not pushing on the bendy parts
3 - flat plate with hole, goes against the hoop lip
4 - washer and nut, pushes flat plat and hoop

Hold it all up there while applying a bit of tension to get things started, not sure if this is any better than a carefully watched block of wood method.

I made something like this to pull rear wheel bearings that's how it came to mind.

We need a tool crib.
