Direct Drive Help

Hi All,

After some coupling issues I have decided to change my EV to direct drive and need some guidance. I have a Warp 9 in a Suzuki Vitara. Vehicle only weighs 1 tonne. It is not the yoke and spline version of the motor so I will need to somehow get a keyway uni joint or yoke and spline setup. I have seen that you can buy drive shafts with a yoke and spline built in. Would this be an option.

Also, is there anyone in Victoria, or Melbourne who would have the knowledge and skills to set me up?

Any assistance appreciated.

Regards

Andrew

here is the previous thread you had...
viewtopic.php?f=18&t=4442&p=55411&hilit ... iff#p55411

I do vaguely remember seeing a motor directly coupled to the diff - no tailshaft.
It was bright yellow.
Anybody know where this thread is?

An alternative is to fit a center bearing like the bmw.

@Johnny got a sliding spline made for his Vogue at Precision Balancing in Melbourne http://electricvogue.blogspot.com/searc ... -date=true
I think his motor was imbalanced and so was the tailshaft.

Sorry I should have piped up earlier. The motor was slightly off but my main problem is my 50 year old differential. Still driving on it though. Friends who have been in the car at speed say I'm being a bit over sensitive about it. Precision did a good job and we're most helpful. Given the length of the tailshaft perhaps I should have gone for a split shift.

Back in the days of the Ford LTD and Landau (stretched body Fairlane and 2 door Fairmont) they suffered tail shaft vibration because of the long shaft and possibly because they weren't put together quite straight. The go was to put a hose clamp around the tail shaft, turn it to put the screw part in different positions as well as slide it up and down the length of the tail shaft till the problem was sorted to the point the owner either gave up or was satisfied :lol: Might be worth a try
