|
|
I've got a pair bought from the same company which will not go together. I taper filed the holes which do not match, so they start, but it will not still mate completely. I'm now working on pulling 4 of the dowels, and leaving the ones that match the original flywheel pattern (hopefully).
Can someone please tell me of a company that will sell a set that is reamed so they match. |

You do know that 1 of the 8 pins is slightly offset. This is called a SPG pattern. It is so the flywheel is indexed when everything has been balanced. Turn the flywheel 1 pin at a time till you find the correct match. _________________ 2017 Street Comp Champion - Thunder Valley Raceway Park - Noble, OK

Sounds like the culprit to me. |

I bought a crankand flywheel from DPR it fit fine a lil tight but no probs.The off set can be a little tricky it only goes on one way that took me a couple turns to try and match it to the off set.
I was told by them also when i set endplay only use the 4 original dowel pins so it goes on easier and comes off easier. |

Thanks guys. I've heard good stuff on Berg and DPR before. The offset is not the problem, I'm a machinist by trade and am working too much overtime to be bothered with fixing someone else's mistake. I broke a 1/4-20 tap in one of the dowels and will finish getting it out on Monday. It would be more cost effective for me if they didn't put any holes in the crank at all, that way I could have simply used the flywheel as a fixture to ream the crank. Oh well, live and learn....
Thanks again for the info. DPR and DMS |

Why would a shop 8-dowel a flywheel without a crank attached to it?
The SPG jig is a cool tool no doubt, but unless you have the crank and flywheel mated together before drilling/reaming would be hard to match separately.
I stopped using the SPG pattern. I just use a Hartford SuperSpacer to space out the 8 dowels centering on the one original stud. I just put a matching mark so the two pieces will mate in the same position.
The beauty of it is that you can even misindex it and still match!
Nothing like precision toolings. |

Why?
A flangd crank is the best way to secure the flywheel, rather then trying to band aid the normal setup. And face it, 8 dowel, wedgemate, weldmate all are band aids.
