clearance is no issue, u can pop in a 37 diff into an old car no problems

(have put 39 in TA05R without trimming, 40 needs a little diffcase trim)

if your belts ain't brandnew there should be enough room to stretch over,
at most you might have to loosen maybe 3-5 clicks on the diffcase

ta05v2 belts are longer, you'll need 18 centre pulley to take up the slack

it uses the 37t pulley so you'd have to convert to 18t center pulley and change belts

Hi guys. Im very sorry if this has been answered before and my search didnt turn up what Im looking for either. I have a TA05 with a 3.5T brushess in it. The problem is the rear diff slips because of the high power. What is the best solution to this? The gear diff conversion? Better style balls?

Either a gear diff, or a spool with a one way up front

Can someone help me out here.
I want to fit the Gear diff and front 37T pulley to my TA05. Is this http://www.speedtechrc.com/store/ebp...id=866&id=7155 the correct front 37T pulley because I can only see 3 holes for the balls to fit when there should be 8. Im missing something but what?

balls go in the outter 12 holes. least they do in mine. those inner 3 are for if you bolt up a spool.

OK thanks. So it takes 12 balls and larger diff rings I have discovered? Is this the correct part number I need for the rings?

This might helps. The IFS-R uses the 37T (53988) while the TA05 uses the 36 width pitch-18T (53935).
The IFS uses the 54045 and the standard uses the 53897

Since the pulleys are different sizes I would use the 54045 with the 37T. Also since the pulley sizes are different it affects the FDR so.... use two 37T pulleys & two belts and use the IFS internal drive ratio of 2.055 instead of the 2.25
If you don't want to buy a second belt & pulley the Internal drive ratio will end up somewhere in between.

Understand I haven't done the conversion myself but have been looking into it.

You can find both manuals here

Thanks for that. I think the TA05 belts will fit the 37T. Mine are adjusted half at half way with the 36T so there should be enough adjustment left for 1T larger.
The diff rings are what I am not sure about. My previous link isnt working. Are these the correct ones for the 37T?

Diff rings??

I figured they would be pulled out since you're changing over to a gear diff.

Update: It looks like you don't even need the pulley. Look at the gear diff kit

http://www.tamiyausa.com/product/ite...oduct-id=54312

The 37T is on the left ( diff cover) and the gear diff case is the one in the middle.

Also when the pulleys are different sizes (front vs. back) you have a power in-balance. I think Over drive is the term which will affect handling. Also I just noticed to reach the IFS internal ratio you'll need to change the center pulley too. Starting to get messy isn't it.


But yes, 51287 is the proper diff ring for a 37T pulley per the IFS manual

Yes I know need to fit the 37T pulley up front aswell to have a balanced drive. Wasnt sure about the rings I needed for it. Centre pulley you can leave and adjust your pinion to suit the new final drive ratio.

Another q if anyone knows. I want to fit a 37T solid spool up front. My problem is finding a spool that the 37T (3 screw) pulley will fit onto, AND fit the TA05.
The spool for the TA05 is a 4 screw mount for the pulley so the 37T pulley wont fit cos' its a 3 screw mount. The 416 spool is 3 screw and will fit the 37T pulley but will this spool fit in the TA05?
Will http://www.rc-mushroom.com/product_info.php/3racing-416-solid-alex-p-18891fit in the TA05?

Thanks for any help..

EDIT. Ive done some more searching and I dont think the 416 spool will fit the TA05.

A simpler question:

What is a part number for a front spool to fit a TA05 ISFR?
