101 Water Pump

**101RRS** · 14th April 2010, 07:45 AM

Because I purchased it, my 101 sat for approximately 8 years and recently some corrosion related issues in the cooling system have shown themselves (corroded through LPG converter). The cooling system still works fine but some precautions are in order.

Repco quoted $880 for a water pump

but I just want to carry one in my tool kit just in case.

I found this one WATER PUMP RANGE ROVER 1970-86 LONG SHAFT WITH THREAD - eBay, Other, Car Parts, Accessories, Cars, Bikes, Boats. (end time 12-May-10 19:34:46 AEST)

Is says it has part number STC 1610 where the 101 parts manual has a part number ERC2893 and also indicates the water pump is unique to the 101.

Will it fit a 101 3.5 and what is the relevance of a "long shaft with thread". My 101 does not have a viscous coupling as the fan is directed bolted the the water pump.

Any advice appreciated.

A quick Google of ERC2893 brings up https://secure.pablanchard.co.uk/pro...roductID=35238

STC481 was ERR2893 at 40 quid.

or from 101Spares $150 - Land Rover 101 Current stock - page 2:

If it sat for that long i would check the condition of the timing cover behind the pump as they tend to corrode, i had to the one on my old rangie welded up which also warped it. Had to set it up in my dads milling machine and re surface the pump mating surface.

I got one of Anthony Johnson for $165 and one from FWD in Brisbane for the same amount. Anther Rover Ripoff place close by wanted $285 for the same thing.

QH brand # STC 481.

Bolted straight on to the engine and viscous coupling.

Cheers,

Peter

Yes - there a range of options. Anyone know what a long shaft with thread means in the ebay ad.

Yes Garry. Very interesting question.
I'm only guessing here but it looks to me as if there may be a key way in the shaft. A pulley for some type of belt to drive it would then be held on with a locked nut. I'd guess this arrangement would be used in a vehicle which uses this motor and has thermatic fans or an alternative method of driving the fan.
Possibly for a Strange Rover (those ones made years ago with a rear mounted motor and the radiators on the roof behind the head).
I might pop out and have a closer look at one.
regards
Mick

Looking at MicroCat, it looks like there is an adaptor that is bolted on and to which the viscous coupling is bolted.

When I rebuilt an old Rangie pump years ago it had a pressed on pulley like that, the viscous fan threaded on the front and the pulley bolted on the flange. It came off easily with a press, I think I fitted a Holden drive flange instead. I cut the shaft shorter and bolted on a fixed fan and smaller pulley, to reduce overheating in a 4.4 powered 2 door. So pulley change is not too hard to contemplate.

Hello all. Am I missing something regarding the viscous coupling ? Mine gave out two or three years ago so I drove a self tapper through it and have been running it as a solid drive ever since. Does the viscous drive really do anything important or are we better off with solid drive here in the Australian heat anyway ?
