Machine shop time, How many hours to prep case, crank, bearings? Options

[Phoenix914]

Greetings All!

I just recently dropped off my 2.0 (GA) case and 71mm crankshaft to get checked at a local machine shop in preparation for a rebuild. Today they called and said for align bore, decking the registers, polishing the crankshaft, and mocking up the assembly with fitted and numbered main bearings it would be 30 hours of work.

Does that sound reasonable? It's honestly a lot more than I expected and will add $$$ to my budget for this rebuild.

Should I look for another case, maybe a 1.7, that is in better condition or has already been prepped?

I'm not an expert builder and some things are worth paying for, but man that's a lot of money!

Thanks for any advice!

Not that outrageous. Most machine shops price by the component job (line bore, deck, polish crank, etc.) not the hour. But on the whole, your talking about man hours just to do mock up work fitting, and measurement of bearings that you could be doing. The shop expects and deserves to get paid for their effrots.

Unless they do lots of setups for decking for example, you're goint to pay machinist time for a one off set up. You're talking 1-1 1/2 hour just to tram the head of the mill, put the case on the table. and get it mounted securely but yet without deforming the case that will then spring back when unbolted. Find the fly cutter, make sure it is set up well, and then do the cutting which is another 1/2 hour or so. Now unbolt that case half and do the other.

You get the idea, it all adds up.

I certainly don't begrudge anyone getting paid for their work. I appreciate highly skilled people who can do work I wouldn't know how to start.

This was just a sanity check, mostly. Thanks for your experienced input, gents!
