Machine Shop in Seattle or BC
 

I am looking for a machine shop to do some work on my crankcase. As I live in Northern BC, does anyone have a recommended shop in Seattle, WA, or BC?

What needs to be done? What case do you have?

Jeff

A line bore at least.

I dont think John Walker does his machining in house..

I am using Steve as well for my heads for the 3.6.

jeff hines can do the case work. he's in mukilteo. 425 275 3527. i do heads here and some other things.

John, can you email me the price to get a set of 3.2 heads done? I have 2 sets to get done this spring. I will gladly drive them down.

Thanks, Jeff

Thanks for the information. The engine is a 911/81, serial # 6371441. It is a ROW engine from 1977. Yes, it is a 7R case. But, no Thermal Reactors. #1 Main Bearing spun, and I have groove on the case, and wear on the front inside of the case. Hopefully, the case can be saved.

Now, if this was an industrial device, and made of steel, the case would be welded and then machined back to original specs. My question is why this can't be done with Mag or Alum cases. I checked on the web, and there are welding procedures for magnesium. Why can't a welder put a number of passes over the #1 journal, and then re-machine it?

You might try Ollies as well, I have heard good things about them, but never dealt with them myself.

when the main web gets hot from the bearing seizing, the webs actually shrink and you end up with a gap between them. torque the halves together at the mains and shine a light thru one end while you look for space between the webs from the other end. it's junk if you see the light.

Unless you are partial to the numbers on that case, You are better off starting with a different case. 2.7 cases are plentiful .

Will resizing then line boring the case solve this or is junk JUNK?

Try Jerry at Northwest Connecting Rod - 206-763-2487 - if he can't help you, he will probably refer you to someone that can.

resurfacing the case half mating faces, then recutting the crank and intermediate shaft bores could be an option, but only a few thousandths are generally taken off, not the millimeter it may require to clean a distorted main web, so it's iffy, and expensive, being that 2.7 cases are common. the reason the main web faces need to mate up tightly is that there's oil pressure going thru the stud bores to lube the crank, among other things, and it would come out the gap instead. (not saying you have a gap though.

the worse part of line bore is the price of the main bearings....OUCH!!!
