Cam Shaft Taper Pin
« on: March 10, 2009, 03:37:57 AM »
Well Im on the hunt for a taper pin that holds the cam shaft retainer bushing.
I purchased a No:6 and a No:7 pin only to find that the no:6 almost drops thru
and the no:7 doesnt fit the hole.  This is on a Powerline 12/1

 I used a #6 from McMaster-Carr and it worked fine in my JKson (powersolutions) 6/1

P/N 98390A344 - Plain steel taper pin, #6 x 1-3/4" long.
0.341" Large end diameter, .305" small end.

if it were me i would go with the larger pin after first resizing the hole with a reamer
those reamers are cool, work exceptionally well in a hand drill

that way you know you got an exact fit without the need for a sledge hammer to
get them in.

Well I had so much trouble getting my old one out, I had to drill it.  I also had the same problem finding an appropriate replacement pin in my area.  At that point, I shifted to a allen head shoulder bolt with nylock nut in place of the taper pin.  It was a simple matter to drill out a straight hole using the remains of hte old pin to align the collar on the shaft.  It is not that critical of an application to hold the end collar on, so I had no issues doing this.  It is also a lot easier to get off if future teardown is necessary...

Thanks Ronmar I think I will do that.  I have looked at reaming it to the next size but I think a no:7 will be to large.  In looking at the pin in the collar it looks to be off center.  So I'll drill it out and use a bolt or a roll pin.

Thanks

I also see no reason why a properly fit roll pin wouldn't work just fine in this application...
