roe crank pin kit

Good info. Thanks!

I have both the Paxton and Roe pin kits installed. Initially the Paxton alone. I calculated the added rotational resistance with the Paxton kit (this is 3 years ago so it is all based on memory). I think it was somewhere around 25% increase. That was with 1/8" solid pins. The Roe is larger diameter roll pins. The difference is not all that great, but the Roe does have higher overall strength.

As to the expansion issue it is not a factor. A steel pin in a steel crankshaft will have the exact same rate of expansion.

The most important aspect is to drill the hole straight and not at an angle as AB did. His issue was installation related. If it is not straight removal of the damper will be damn difficult, if not impossible.

I agree, when i drilled mine, i put the damper on a drill press and drill the first part of it that way. then used those holes as a guide to drill the crank (in the car) and it came out perfect. it took time though to get it set right.

I thought you were using an ATI damper. Knowing Doug, I figured if he recommended a pin kit, then you are probably using an ATI damper since that's what he uses.

It's no theory. It's straight out of the ATI installation instructions....."It is highly recommended that you use anti-seize lubricant on the crankshaft before the hub installation."

As Plum mentioned.....use a drill press.

Good luck!

Oops, Sorry I just realized that I didn't answer your question.

If you don't use the anti seize it will be impossible (or extremely difficult) to install the hub, even though you've heated the hub to thermally expand it prior to bolting it into place.
