Connecting cups questions.

[vrooom]

I have a TM2 v2 car with very worn connecting cups... center and diff output.

will TS412 - Connecting Cup "Ultra-Hard" will be better replacement than driveshaft puck someone making on here?

or should i buy standard connecting cups and be done with it?

Hi vroom,

The standard ones wear quite quickly. I once ran 12000 oil in my gear diff and on high grip Astro the cups had a notch in them after one meeting.

I have put my C-Drives on the out-drives on my TC02C and not seen any wear yet. Several people have gone for the C-Drive on both the TM2 and TM4 centre shafts and report great results. No negative reports so far.

The C-Blade is hard and transmits the torque more efficiently because it has flat faces running against each other and also the pin is in a round hole so that also has a much larger bearing area than the pin rubbing against a flat face. The generation of the notch on the standard arrangement is effectively a "machining" operation and you don't do that without using valuable energy.

But I only have one C-Blade in stock until I make another batch. :(

Take a look at the facebook page in my signature.

Cheers

Definitely go with the c drive very happy with mine, runs very smooth and quiet and no play:thumbsup:

x2, I also run the C drive in my V2, and it works great!

I use the hardend outdrives on my diff, but the problem with these is that the pin of de CVD will ware, so you wil get play anyway.

So I think I have to order the blades for my CVD's @Clive :D

I'm making some C-Blades with a slightly different profile for use on the TM4 rear prop-shaft and it looks as though they can be used on the diff outdrives on a Durango as well!
