Topline Crankshaft

[topekamk3]

Has anyone here ever used a Topline Crankshaft? If so did it hold up? How long was it run for, ect? I'm about to start a rebuild and my motor has a spun rod bearing so might go with a Topline Crankshaft since the price isn't too bad. Heres a link

Win !!

Ok I'm assuming this is a reman Crank?

Do they say what size bearings it's been machined to?

In general going under 10/10 on a 7M crank is bad.

I am thinking that it is. Not sure the bearing size it is machined to. Here are the specs it shows so I will need to search to see what the specs of a stock 7m crank are 83mm(3.268") - 85mm(3.35") - 2.3616/2.3622" - 2.0466/2.0472"

And here is the company's website http://toplineauto.com/index.asp I wasn't sure if anyone on here has any experience with them at all.

7M Cranks are Induction hardened from the Factory, it's quite shallow so 10/10 is about it before you hit the Silly Putty part of the Crank

I'm glad to find this out that way if I reuse the crank thats in it I will know not to have it machine past 10/10

UPDATE:Topline Cranks are reman's and then cut them up to 20/20. However the rep I spoke with said the 2 they currently have in are cut only to 10/10. He said in most cases they are 10/10 but every once in awhile they do have to do 20/20. He also told me he could not even get close to the price Nopi sells them for. However Nopi does have the cranks drop shipped from Topline.

I don't recall seeing a crank that needed to be resurfaced that was approved for a resurface. That doesn't mean all the Toyota cranks were unservicable, I just didn't see any. Supra owners aren't the only people that run an engine out of oil.
