The pump on my ex MOD 110 has just started weeping and the bearing
feels shot, I have a RR V8 with a sound pump but the viscous hub looks
different. Are there any basic differences between the 101, RR and 110
V8 water pumps? Will my current viscous hub fit the RR pump?

Prices locally seem to be about GBP80, yet mail order seem to be about
GBP40 plus postage!

As I found out when swapping a 1982 Rangie V8 engine into my ex MoD 110,
the Rangie pump is a fair bit longer than the one on your 110. The
viscous fan will also fit differently. If they're the same as mine, the
110 one will be held on simply by a thread on the end of the pump
threading into the fan unit, and the pulley will be held on by 4 nuts.
On the rangie, you'll find that a single large nylock holds on both the
pulley and the fan. If you do swap it, you'll have to swap the whole
lot. I can't think of any reason it won't just swap other than the
length issue - you don't want that big nylock too close to your
radiator, of you might find they meet when you go over a big bump...

4-bolt pulley fixing, 3-bolt pulley fixing, both with integral male l/h
thread for viscous hub, 4-bolt pulley fixing that also retains a removeable
l/h male threaded boss, long thin l/h threaded stub that passes right
through viscous hub and takes a separate nut, those are the ones that spring
to mind, no doubt there are even more variations than these!

Dare I say, you get what you pay for..... having said that, £40 isn't
excessive if it turns out not to last too long.

Thanks Paul, Badger and the one welcome help from a commercial reader
on the group.

In fact I found it a b****** to get off, firstly the stud was seized
and then I thought I had just about enough room to clear the radiator
but the bottom long bolt wouldn't clear the thread. I took the rad out
and was pondering how to get the viscous unit off when I realised I
was out of time to get the part from a dealer some 20 miles away. Only
german machines normally need this much dismantling for a small job, I
did this same job on a ford 6cyl diesel last month in half an hour.

I will set to tomorrow and will use new parts, as well as the advice
here i think the time necessary to swap another old part will probably
not repay itself, it would also make my spare engine less usable in
the future.

Advice noted, not worth the risk, so replacement pump it is.
