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! |

I can't believe it's been mid-September since the last post in this thread. I decided to follow Mark Henry's advice and send the engine case to EMW. The shipping cost was more than the work! The bore was standard, so they did a first cut align bore, and then decked the registers and removed/tapped the gallery plugs.
I left the crank, pressure plate, flywheel, and cooling fan at the original machine shop for them to clean and balance. I'm not sure if I am satisfied with their work, so there may be another update on that. The next steps are to procure a decent micrometer for measuring the crank journals and then ordering bearings. I still haven't decided whether to use the stock connecting rods or buy H-beams - and from where if so. More to come. Thanks again to all who gave me advice and for the incredible pictures posted to this discussion. |
