belt life?

[The_Ne-Go-She-Ate-r]

Could you guys help meout on how long the average bekt last on a tc such as the mr4 tc pro?
Thanks

it depeneds on if small stones get court in the belt/pullys.. what pitch belts are u using..???

They're suppose to be 32 pitch if it's a Yokomo belt. They should last you for a few years if you keep the drive train sealed. Also, unless you have a slipper clutch, make sure your diffs aren't too tight - so you have a little slippage there.

YOU DO NOT want ANY Diff slipping, that is very bad for them! What motor are you using, i am guessing the hotter the motor, the faster it will die, just do a visual inspection, heck, just replace them for piece of mind, if you think htey do, them maybe so.

No diff slippage? You gotta have some give in the drive train to keep the belts healthy. Since when do people not put a bit of slip in their diffs?

[BadRacer]

It isn't good at all to have any diff slipage, this is what i have heard and read in the past few kit manuals i have had. Sliping diffs is not good, you should let the slipper do the sliping and nothing else!

Does the MR-4 TC come with a slipper? Maybe it's entirely different for on-road than it is for off-road?

Why is it bad to let your diffs slip a little? They are designed for that right? Otherwise we would be using universal planetary diffs like back in the old days.

I don't want to mislead anyone but everything I've ever heard about belt drive trains is that there needs to be some give to protect the belts.

Would you want your Transmision in your regular car to slip?

Just think every time your driving your car and the diff slips, that means the gears are getting messed up. This is were the slipper comes into play......it does the slipping for everything else so it doesn't mess up the diff's.

Just trust me on the......slipping diff's are bad!

slipping diffs = heat >more wear on stuff,i have never herd of a belted car that is ment to have a little diff slip...???

The first Schumacher CAT:

It had three differentials:
One center
One rear
One front

The center diff was used to distribute power, in an adjustable way, to the front and rear diffs. The CAT had 80 pitch Kevlar belts and required some slippage of the center diff to keep from shredding the belts when using mod motors.

The first Associated RC-10 had a ball diff that was integral to the spur gear assembly (like the CAT's center diff) and it was also common to run some slippage in the diff to maintain traction on full throttle start.

The Losi JRX-2 ran a ball diff that was the center gear in a three stage gear box. It had no slipper clutch so you were suppose to run the diff with a little slippage. In fact the bench test was to actually hold the rear wheels and apply power the motor could turn the drive train without stripping gears (which was the idea).

These were examples of providing traction control and safeguarding the drivetrain (gears, belts et al) by virtue of the design. These days, traction control is a function provided by the electronic speed control so I suppose they don't manufacture the diffs to do this anymore. My advice was dated.
