Front and rear Spring Bushings 5781 or CO1T-5781-A and 5781 or CO1T-5781-A

[Jacques Reed]

Hi Ian,

I bought similar front pins from Dennis Carpenter however they were Chinese repros. They were such a tight fit on the pins that I didn't use them and waited until some NOS came along.

The Dennis Carpenter ones could have been used with a bit of careful reaming. As most of these parts come out of the same factory in China it is something to be aware of if you use a repro bushing.

The rear bushings of course are much larger diameter and seem to be harder to find.

The originals are of interesting construction. I don't think the bronze liner is pressed into the steel sleeve because it is of extremely thin wall thickness, Unlikely to press in without crushing. I believe the bronze is pressure bonded to the steel similar to Raco Ware in Australia, or Revere Ware in the US. I cannot detect even the smallest gaps between the steel and bronze even at the lengthwise split. I could be wrong, wouldn't be the first time, and happy to be corrected if so.

Bronze bushings on steel pins is preferable but as Lynn says others have used steel bushings on steel pins. You would however want the best surface finish possible on the inside of the bushing to prevent chewing up the pins.

Cheers,
