Need Clutch pack for 10 bolt posi...please help
Permalink  
 


So I pulled the cover off the 10 bolt rear on my 65 chevelle project.

Low and behold, it's got a set of 4:56 richmond gears and a GM 410408N clutch posi unit.

The rebuild clutch pack kit is GM # 231127. I should rebuild it while I got it apart just because.

Searched high and low. Discontinued part number.

Any ideas who might have one?

Randys ring and pinion has zero interest in even investigating.

Nationwide dealer search came up empty.

Damn!!! Any help would be appreciated.

 I called them. They said they never rebuild them and usually replace the whole unit with an Eaton. The Eaton is $478 at Jegs.

WTF is GM thinking on this one?

Maybe I'll just try it the way it is. I have no evidence at this point that the unit is totally worn out.

There is either gonna be two tire stripes or one when I burn out.

 Thanks but the clutch pack in your link is for an Eaton Posi.

 Once again, I'm looking for GM part# 231127 for a Gm posi 410408N, 3 series, S spring style.

Unfortunately, the readily available Eaton clutches do not fit the GM units.

Hi Guys,

The Carbon Steel 8.5 Clutch Kits are available. These kits fit Oldsmobile 8.5 Type O Differentials from 1967 – 1970. These kits also fit the GM Corporate 8.5 Differentials from 1971 – 1987. This comprehensive kit is a direct replacement for GM Part Number 23-1127. Unlike the GM Kits, our kits also include 12 shims (2 of each in the following thickness: .010, .015, .020, .025, .030, and .035). These kits are 100% US made, from the steel to the tooling. We had the metal tested for Rockwell hardness and it specs out the same as the factory. We went with the cross hatch surface pattern (like a Chevy 12 bolt clutch) instead of the fish eye pattern for two reasons; first, the die to stamp the pattern was less costly which keeps the costs of the kits down, and secondly, this pattern offers superior lubrication which will enhance the life of the clutch.













I am a long time member of Team Chevelle ( http://www.chevelles.com/classifieds/showproduct.php?product=55410&cat=30 ) and was having a tough time locating GM Clutch kits for my 84 Hurst Olds. Any questions, please use my contact information in the Team Chevelle ad.
