It was a good meetings, we made a good start on the problems of the world. Will sort them all out next time.
On to the VCU test, I have mentioned it before here, and got a bit shot down...
The procedure (no pics, will take some next time):
- Raise vehicle (rear on ramps, front on jack stands with wheels clear.
- Remove spark plugs
- Disconnect rear drive shaft from VCU (which is still installed)
- Bolt 2 metre (approx) steel angle to VCU rear flange
- End of steel angle or bar rests on bathroom scales (you have two goes to get it out the correct side)
- Put in second gear (manual box required) (this should cause the propshaft to rotate at 75 rpm or thereabouts for the RAVE spec)
- bridge from battery +ve to bottom clip on solenoid (makes starter run)
- read bathroom scale
- Calculate torque from scale reading and length of angle/bay.
- Compare with RAVE spec.

When I did mine I got 280 Ft/lb.
I guess another way to achieve this would be to raise one side only. Chock wheels on the ground. Put torque wrench on back wheel and measure force while cranking engine in 2nd gear. Would have to factor in rear diff ratio which would increase measured force on the rear wheel. This would mean a LOT of force.
