Outer Limits 4x4 Board

Hi

I just got my hands in a 91 swb zook with calmini 6.5 transfer gears installed. I would like to know how do you check to see that it is 6.5 gears.

It has 33" tyres and on the freeway it will sit on 100km eventhou the speedo says 80km and rev at about 3200rpm

Any ideas?

It sounds like you do - assuming 1.65 :1 high range (usual for 6.5:1 transfer gears) means your road RPM is correct.

The other way is jack the back wheels up, put the case in 4L, put some marks on the rear driveshaft and turn the jackshaft (with the gearbox in neutral)

the jackshaft should turn 6.5 times before the rear driveshaft turns once.

Yea had a look and yes the jackshaft turned 6.5 times.

thanks for the help

Do all gearing for the transfer make a whining sound?

I guess I will have to live with it..

shouldnt whine to the point you cant hear anything but the whine. sounds like it needs shimming up and maybe some new bearings......


Have you checked if it has GOOD oil???

Some whine in low range is inevitable.
If it's loud (and I mean louder than any other driveline noise) at highway speed it could be time for a rebuild to factory specs - watch out the clearances/thrusts are correct.

Make 100% sure it's the transfer and not 5th gear in the gearbox though - my car has a whine on the highway but it's from 5th, not the transfer.

Some gears are worse than others though.

Steve.

How many times should a standard 1.3lt transfer spin in the same way?

with the rear wheels y in the air and checking the jackshaft

Should be low 2.1:1 standard low range from memory.

Layto....
