Donkey Doctor....you're right in general but there are exceptions (many exceptions). I'm weary about the bearings because I've bought 'name brand' wheel bearings for my car from a 'national chain' that went bad in 10,000 miles badly heat scoring my axles in the process and the store said "oh well, we can sell you another set"...they sure as hell didn't offer to replace my axles which got toasted because of their defective bearings. Similarly I recently ordered a transmission pan gasket for an old Mercedes and after waiting 3 weeks received the wrong one even though I explained to the 'trained technician' twice exactly what I needed. And so similarly I doubt if a bearing place will offer to replace my motor if they sell me unsuitable bearings. I find that a LOT of businesses are that way and there's a lot of employees/workers that don't know what the heck they're talking about and are plain incompetent morons and will sell you anything. I may sound like my grandfather but it's true that the days of customer service are long gone. TRUST NO ONE is my attitude.

Anyways, just out of curiosity what should I expect to pay for a set of crank bearings for a model 4 stroke engine?
