Re: unnecessary crankshaft removal
Jeff said:
After numerous inquiries locally I tried to chisel it out and even drill it out. There's no choice but to remove it but I'm afraid I'll damage the surrounding metal. Thus I want to take the crank in to a machinist in order for him to machine it out. Thus the job keeps getting bigger. If I knew it would have come to this I would have pulled the engine long ago. I just returned this am with a hoist. Jeff
If you are intent upon lifting the engine without a hoist, you can jack the engine from one or both motor mount areas. You can also secure the engine by placing 2X4's lengthwise between the shock towers/fender aprons. 2X4' s under the motor mounts should also work in a pinch. But I really don't think any of this is necessary.
Suggestion: takes some pictures and post them here. There are several methods of pulling pilot bearings, the race and bushings I have never had a bearing that wouldn't eventually come out with the right bearing puller and, if necessary, a little localized heat (propane). If you do a little homework, you may find a description of using hydraulic pressure to remove the bearing - (grease). I have also seen a slide hammer (dent puller) used for this purpose too. Some of us may be curious as to exactly what type of bushing you are attempting to remove. Is it really the steel race onto which the bearings ride? Or is this some glorified spacer? Is it tapered?
I can understand why you do not want to bugger the crank, but if this is just a bushing that you will be replacing, the new bearing/bushing will not be affected by your chiseling, nor would I expect you could really irreparably damage the crank. (After you remove any burrs, the new bushing will likely conform to minor irregularities on the crank end.) By the time you are through, are you planning to replace the rear main seal too?

Good luck.
