Thread: VC replacement is nigh!

Yep, been there. It's fairly straight forward but you require a press to remove the VC from its casing. I got hold of one of those "pack it away" 12T contraptions for a couple of days. It took a bit of pressure to remove but nowhere near the max. capacity of the press.

A 270 Nm 12V electric rattle gun ($80) is almost a necessity to remove the flange nut from the output shaft and 'nip' it back without putting looong levers in place to torque up the nuts. Safer too! A new bearing, new seal etc and you should be OK. There's a huge difference in price for VCs.

read through Viscous coupling...vicious price ...goodness me, it was done in 2009
good luck with it... PLEASE make sure you have the vehicle absolutely failsafe in terms of being on jack stands...

I did mine last year. The best price I found at Ashcroft Transmissions and really good service. The only special tool I used was a good sized bearing puller to get the VC off the shaft. Otherwise, open end and ring spanners as well as sockets. Don't forget you'll also need the silicone gasket sealer when you reassemble.

Thanks Hoges, glad to hear it's doable.
The rattle gun would be a good thing to have anyway, but I was thinking of taking the unit somewhere to get it pressed off and on again.
So a new bearing and oil seal I can handle...is there anything else I need to be aware of?
I think there is a special silicone for the casing from what I can gather.

mtb_gary, were you able to remove the bearing and vc yourself without a press?

Years ago I did it without a press, it took some patience with a hammer- but doable. Have got to be very careful with the alloy housing though.

Since then I've bought a 2 tone press, and it does it with ease.
A 50cm breaker bar will undo the nut.

The only issue you may run into is if the splines on the rear of the vc won't let go of the transfer case.

Peter, I used a decent sized bearing puller,but no press involved. Don't get me wrong the operation wasn't all plain sailing. But it was achievable.

If you're up for it Peter, some photos of the job would be great.

I was thinking along the same lines poleonpom, will do! I'll make sure to include close ups of my bleeding knuckles.
