I changed mine over to the 418/419 arms yesterday. Crazy amount of spacers need.. but I got the wheelbase right. Front sway bars on.. need to work on the rear one.

I converted my TA05 to a FWD running 37-gear diff and Yokomo 20-mid gear

same diffs as produced by factory & 3rd parties back when TA05 was new. :/

V1 takes ball diff built with 36t pulley, TA04 diff plates, balls/thrust/spring/bolt etc plus TA05 outdrives which came in several flavours:-

std kit S-parts injection plastic
high precision diff joint delrin
billet alu diff joint
(also)
oneway

BiTD some 3rd parties like square, 3Racing & Eagle etc made aftermarket equivalents & spool etc

Have yet to find any newer modern diff from another model that will drop in fit with required 36t pulley.



If any TA05 fan has found a modern easily-sourced drop-in diff unit that doesnít need significant remodelling, please let us know

IMO itís best to switch to V2 belts, 37T pulleys and 16T centre pulleys.

White gear diff you have pictured there is 37t. You can run the V2 spool which is white. Also the black 37T spool pulley from TRF418/419 works.

hiya Raman!
Oldskool OG TamiyaClub crew reunite!!

V1 is 36t diff, 16t layshaft, 113t belt

V2 got 37t, 18t & 114t.

If u use V2 belt with 16t pulley, I fear thereíll be insufficient adjustment range in bulkhead to take up the longer beltís slack.

Also V2 belt stock seems to have dried up these days but yeah if one is running any *tub* TA05 converting driveline to V2 spec makes sense.


White gear diff you have pictured there is 37t. You can run the V2 spool which is white.
yeah 37t & gear not ball thatís why itís corralled outside red tray & not mentioned above

Proper ďTA05 Gear DiffĒ pack pretty much impossible to find even back when, I suspect T only made 1 batch of those along with TA05-Mfour kits.

Also have SpecRís gear diff, thatís 37t too.

Also the black 37T spool pulley from TRF418/419 works.
418 runs 39t gear diff cases, no? But wider.
Read on either this thread or V2 thread
of racers latheing them narrower then using
skinny 3mm (vs 4mm normal) 1510 bearings
to fit within TA05 bulkhead.


Tub TA05, yeah easiest be just using full V2 drivetrain.

but thereís other TA05 oddities like 30th Ann 934, MS, Mfour and of course the VDF & VDFii where thereís no easy option for a slightly (1t=3mm) longer belt to fit 37t diff.

Ahh itís Willy.. didnít realise it.

I couldnít remember the v2 centre pulley? Itís 18? Anyhow thatís what I meant. The larger centre pulley from V2.

I wrote the 418/419 black spool fits. You are correct, the 418/419 diff is too wide.

On my V2 I purchased TA06 complete gear diff (pulley version) and then used the DB01 gear case with the TA06 internals and outdrives.

Works really well and most of those parts are available.

Belts are probably the hardest part to get these days - and new tubs are rare as well.

Ya if you've already got V2 then the Mfour gear diff is easy drop in.

Internals shared widely but Mfour sparepart diff case not easy to find when I went looking last month only Tamiya USA maybe & none at TonyTParts. Got some DB01 diffs to test fit instead; not quite sure why we must need TA06 outdrives when the DB01 cups are nearly same in all dimensions... Only one way to find out

A serendipitous discovery today whilst trawling parts lists - seems the Yok BD8 runs diff with 34t pulley. If anybody's got one to test that could be handy. Right now a BD9 is dirtying my desk & it's got later 40t diff.

The larger centre pulley from V2.
Spur layshaft uses pulley inserts, can find 16-20t no dramas. Maybe bigger still from drift specialists.

Everything on hold ATM trying to source some 114t maybe 115/116/117t belts too for tubs.

Plus another item on bucket list is to griptrack a VDF this will get gear diffs to bring it up to 2018.
Went looking for Ackerman rack but turned out I already had one in the salvage pile.

I believe the M-Four diff case is the same moulding as the DB01 case.
I think the DB01 outdrives are shorter than the TA06 items - but it's a couple of years since I put those diffs in and compared them.
