Mike,

i did this getting ready for reedy.. you can fit another locked pulley on there. one pulley tho will have to slide into the bulkhead. loosen the bulkhead (the one that doesnt hold the motor) and slide it outwards... then assemble the entire center portion..then slide back in. its kinda tricky.. but enough room to do. hope this helps.

Nope bone stock TA04pro ones are 8 degree, 415, evo 3 and the racing front c hub set are all 4 degree ones. Rick

i did file a flat on the shaft... and filed down the spur hub a bit, and one of the pulleys, too. ill see if i can find a pic. its prolly on my pc at home, so it'll be this evening.

i actually went back to the oneway setup on the primary car to be ready for the Memphis TCS race... although, ill prolly run the 414 anyway.

Hi all,
Right. First post in here me thinks...
I've only just got back into Rcing after having spent a few years away, and the YokoMR4-TC (belt version... good for a front 415 diff!) i have is a little on the out dated side, so I've begun looking for new car. Oringially I was swayed by the Pro4, then the T1-FK, but then i found out about speedtech and the price of importing kits.... so I started to consider the TRF415 too.

I've just spent most of the day reading through the thread, and I have to say, there will be a new member to the club as soon as speedtech get some back in stock

What really helped was, purely by chance, meeting Ben Cosgrove earlier this week, and he mentioned about how good the car felt over the xray, and the results speak for themselves....

Anyway, just to check, I've gleaned from the thread there might be a few parts worth picking up at the same time as the kit. feel free to correct and errors or add anything in.

1) Rear Alu hubs (for the inboard rear toe, and camber link options)
2) 3 hole pistons
3) sets of blue and white tam springs
4) carbide balls for the rear diff

I've looked at the spool too, but i might wait on that until the fixed lay shaft is out, as too be honest all my racing at the mo is indoors, and i've run double one-ways in the yok for as long as i can remember (even when racing indoors on slippy wood floor ), so i'm quite happy driving with them.

I have to say I deffiently feel like i've learnt alot about the car today, from reading through the thread, makes me quite excited......

Regards
Ed

Default 8 deg hubs

As an add on wont the TA04 8deg hubs actually provide 6deg on the 415?
My reasoning is form what Rick posted earlier....
Originally posted by Rick Draper
I hate to upset you all but there is no 6 degree front C hub. Me and jonny boy were looking at them today and cracked open a 415 hub carrier set and also a TA04 racing hub carrier set and the sprues both had exactly the same part numbers on. The reason the TA04 racing set is labled as a 6 degree set is the fact a TA04 has 2 Degrees of kickup on the wishbone meaning it has 4 degrees on the C hub and 2 Degrees of kickup = 6 Degrees. Rick
So 8 deg - 2deg (kickup) = 6 deg

just a thought...

The belt Stabilizer is basicaly a belt tension bearing that bolts on under the upper deck where the ant. mounts...I belive it`s so you can run your belts a tad bit losser..?? who knows and the heat sink beam is a nice little finned bar that goes between the rear bulkheads that...well acts as a heak sink and a stiffener at the same time.. be belive it`s a trick By Tamiya to make getting the rear diff out or adjusting rear belt tension more difficult j/k

now that you mension rear diff i have a bit of a puzzler!

The track i run at is super fast flowing but also has some really right turns. I found the car to be really back endy at first time out then TRf driver told me that i should tighten up the rear diff more then "just until it dont slip" as its way too free ( i guess it would be awesome indoors or for twisty tracks though ), anywya i tightened my diff up and it solved the problem , car was awesome BUT the diff feels really "clicky" and not smooth at all, it wants to lock up when it click when i spin the wheel by hand. if i loosen it off, its fine.

any idea anyone?

thanks

Tarnjit
