Speedometer Question

[Eric46]

My truck is a 1970 F-250 4x4 - NP-435, Dana 24 T-Case - with no speedometer reading. I disconnected the speedometer cable from the T-Case and spun it by hand...its good. I pulled the driven gear out of the t-case...it is not plastic, rather it is a metal gear (20 teeth)...and the teeth are worn off. The drive gear appears ok and spins when the driveshaft spins...looking through the hole in the t-case.

I didn't see in the 1970 shop manual where the speedometer cable attaches to the t-case. Were the 67-69 trucks different than the 70?

Any ideas where to find a new driven gear?

Thanks

No.....they are the same for a D-24. You are looking at the correct spot for the transfer case (on the back side of the T-case going to the rear drive shaft).

If the teeth are worn off of it, sounds like it wore out (due to misalignment?)

[Eric46]

Yea...I don't think it was turning as one side is ground flat. Any ideas where to get another gear?

The fastest way to get a gear is the local parts store. Then check online vendors for our trucks. As welll as ebay rockauto etc.

Try these guys. I have bought Speedo gears from them after making gear changes in the past.
Their info is very detailed & their gear calculator works well too.
