voodoo lives...again !
« on: 12, May, 2009 - 19:15:10 »
Voodoo ended the recent London run with a nasty crunching noise coming from the gearbox....so it was not a surprise to find bits of broken plastic in the gearbox when I took it apart earlier today  ::)

Although it is disappointing to see another gearbox fail, at least I know what the problem was and have now replaced the gearbox.

It is also further proof that our decision not to continue with 24v kits was the right choice to make, even though the motors cope really well.

Despite advice given elsewhere, from experience I would say that the gearboxes are simply not strong enough to cope with the extra oomph  :(

This particular gearbox lasted on Voodoo for 2 years, having been used on all the 2007,2008 and 2009 meetings and a few laps around race tracks at Bruntingthorpe and Brooklands, plus the Welsh Autofest run. I don't know of any other 24v c5 that has been used more than Voodoo - so I feel it's had a proper road test & I've had my monies worth  ;)

As long as my box of spare parts is big enough, Voodoo will keep on rolling  ;)

Dismantling the gearbox doesn't need the two bolts removing, I used small bits of plastic cable tie to keep the fingers raised and then a set of grips to gently tug the gearbox away from the motor. Using a small thin screwdriver I also lifted the other fingers that grip the gearbox, just to sort of break the seal. I hate that part,because I'm always worried I'll damage the gearbox casing  :-\

If you've already removed the bolts though, I'd use the opportunity to clean up the motor and check the brushes etc. Well worth doing .

Thats what i intend to do, he needs a good service as its a year on Thursday since i finished rebuilding him and he's had quite a bit of use, thanks for the reminder Karl of the removal of gearbox cover, wish me luck.

I'll post some piccies a little later, I've just changed our computer and I'm experiencing a few adjustment problems... :P

The damage was a little unusual in that the teeth in the brown outer casing suffered the most. Two of the small white cogs have a little damage, but not much :-\

Piccies of the damaged gearbox removed from voodoo;




..to its credit it was still running, but I doubt it would have kept going for much longer.

Quite a bit of damage there, did you wipe some grease away, or is that how it came off ?
