Axle Shafts

[Red Horse]

I have a CRD 62 carrier and I am told that a CRD 118 is a replacement. The only issue is the CRD 118 spec sheet says the axles have "involute" splines. What are involute splines. the CRD 62 I have has straight splines on both ends.

Can anyone help me out.?

Involute splines are tapered sides, kinda like a gear would have. You have to use PINS to measure the size, as the maj/min are basic reference dimensions.

Here is a website I found that you can look thru to see differences. It gets pretty technical, but might give you some idea of what I'm talking about.

Freighttrain,

Thx for the response. Looks like I'm gonna have to study this!

Don't break a sweat on it, in all it just means that the two axles WON'T interchange.

You'll need to use crd118 axles in the new carrier. You're crd62 axles won't fit.

10-4 Freightrain- My problem then will be the guy wont sell the carrier plus the axles blah-blah. I'm afraid I' going to be going down the road at 45 MPH with my 9.05 CRD 62!
