Thread: Viscous Coupling replacement

When I tested my vc recently I had a 3/8drive 9/16 with a 6inch'ish' extension, and an open ended spanner on the bolt side. I had to rotate the prop shaft to get the last bolt though.

It'd be interesting to test the vc with a tension wrench, as they're supposed to have a certain amount of initial resistance.

Also, I'd be loosening the flange nut before you take it off the case.

Thank's Benji. I shall persevere tomorrow.

As for the initial resistance I do not feel any resistance in the front wheel once it is raised off the ground. Hence it is stuffed

Land Rover Prop Shaft NUT Tool 1 2" Drive DA1119 | eBay

The tool DA1119 is almost indispensible for this sort of work. It's used across quite a few LR models. "Plan B" alternative (not real good) is a short thin-walled 3/8"drive 9/16" socket fitted with a "wobbly" extension bar to allow you to offset the ratchet. The nuts are nylocks and are supposed to be torqued to 50Nm (35 ft lbs) so they may be requiring significantly more than this to free them.

I bought one of the DA119s a few yrs ago and I used it with a $70 1/2" drive 12V rattle gun (otherwise used for removing wheel nuts) on the 9/16" flange bolts. A 'gentle' touch up with 250 ft lbs pulse gets things moving. It's especially useful for removing the large flange nut

Make sure you get a spare seal for the flange when removing the VC from its casing. The VC needs to be pressed out....

Thanks guys I will be getting one!

In the meantime I have removed the 4 nuts on the end of the prop shaft that connects to the transfer case and managed to undo the big nut . I then thought whilst I'm on a roll why not try and remove the front bolts of the prop shaft and remove the prop shaft completely to give me a bit more room?

This is the reason why we should spend a bit more on good quality tools! I was lucky this time, and did not get hurt, but it could have been pretty nasty! I was using the open end on the nut without any extension bars on the spanner. It must have been the spinach I had for tea last night .
