Used re-ground crank suppliers?

Bruce (VA) · Feb 25, 2013

My neighbor needs a new crankshaft for his 1950 8N sidemount. Option A is for him to buy one already re-ground w/ the correct bearings. Option B is to buy a used one from a reputable source & have it reground here. What are your recommendations for suppliers for a re-ground crankshaft?

For Option B, John Smith is temporarily out of stock & I've already sent an email to Jim UT. Other sources are welcome.

Thanks!

How about this site?? Or maybe nnalert. Then of course there are people like me that have parts on hand. I have a front mount 8N with a cranked block so I have a crank shaft but maybe different then to side mount that I do not know. But shipping is a killer. Last time I shipped a crank shaft out east it cost the guy $50 for shipping due to it being so heavy

Have you checked with Just 8N's? Don't know if they have any, but they did help me out with a part a while back.

Bruce.........re-grinding a crankshaft is common automotive machine shop procedure. Why do you think yer neighbor needs to buy one? .........Dell

From what Bruce said it seems pretty clear they have already determined the old crankshaft is not regrindable. Cracked and/or badly galled or reground to the limit crankshafts are a common occurrence especially in 70 year old engines. That's why magna-fluxing them before regrinding is also a common machine shop practice.

NAPA machine shop said the key got loose & wore down the end of the crank & wallowed out the pulley as well.

Well duhhhhh.......

I forgot they might have them. I'll tell the neighbor to call.

Bruce (VA) · Feb 25, 2013

I didn't think this site would have re-ground cranks.

Yesterday I took 10 crankshafts to my friendly machinest. My instructions to him were to check them carefully and tell me what each one needs (grind, no grind, how much to grind or just throw it away).

My thinking is that a guy having an engine rebuilt will probably want all his machine work done by the same guy. Also your local machinest will be more willing to stand by the finished product if he's the one who did all the machine work.

My plan is to sell the aforementioned crankshafts with full disclosure as to what my machinest said needs to be done. He says he has no problem with me giving out his name and phone number. He stands by his work.

Bad news is, this is a project to fill any down time he has so it might be 2 weeks before I have them back.

Tnx much Jim! I'll let the neighbor know. My bet is that he needs to move quickly as the grass will need cutting around here in a month & we still need to put the tractor back together after he gets the engine out of the shop.

Jim.UT · Feb 28, 2013

I probably won't have anything for him before he needs to move, but I've been wanting to get these cranks to the machinest for about 3 years. Your email was the final push I needed to GET IT DONE!

I've got a few good cores on the bench (generator, water pump, etc) that I need to just get rebuilt & have spares around. I've got a spare carb & spare front distributor. They are nice to have. Now I know where to find a replacement crank! Tnx

f all it takes is a mic you don't need a machinist. Is your machinist friend going to magna-flux them? If not what are you going to do when a customer tells you the one he bought is cracked and unusable? IMO you are better off having them magna-fluxed and reground to a known good size and selling them certified ready to go. That way nobody gets any surprises.
