I'm helping to repair a 1987 K75 and found the pushrod is slightly bent.  I found a replacement online that claims to fit a K75 but doesn't look the same in the photos.  The pushrod is from a 1990 K100LT.  Will this pushrod fit a K75 transmission?  I believe the P/N from the k100 is 23131451120 and the K75 is 23131454786.

Are you talking about the pushrod for the clutch?
Both push roads are almost idendical at the exception of the tip.
The tip is inserted "press fit" into the rod and you will have to get the one from the K75 to be inserted into the one from the K100.
The pushrod is a hollow tube with an insert at both end.
I did it before, and it works.

Can a K100 transmission push rod be used in a K75 transmission? Pushro10

Yes, Bert, the pushrod for the clutch.  I don't want to replace the tip between the two rods because the original tip is what is bent.

The K75 pushrod has a flange near the tip and the K100LT does not have such a flange.  The Ebay seller claims his K100 pushrod fit all K-bikes 85-91.  It would be an expensive mistake if I believed him.

UPDATE: we managed to straighten the original pushrod and the transmission is back in place.  However, it would be good to know if it is interchangeable, all the same.

to have the correct fit to the K75 diaphragm spring the K75 pushrod needs to be used or you WILL get trouble further on.

Let me guess the ebay guy is safaricycle.  Everything K that guy has fits all models.

And because of the different shape on the clutch end of pushrod and the diaphragm
spring center......a K100 pushrod will become too "long" if mounted on a K75.
