Axle Shafts

Recommended Posts

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.

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!
