101 Water Pump

[101RRS]

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:o 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) (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=360252171261&ssPageName=STRK:MEWAX:IT)

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/product.asp?productID=35238

STC481 was ERR2893 at 40 quid.

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.

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.

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.

Looking at MicroCat,

What is that - a small pussy or a fat kitten?

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 ?

GarryI thought a Micro Cat was a "D 0.05"

Mine has had it removed and a fixed fan added. My understanding is that as the engine heats up (excessively) the fluid in the viscous coupling "locks" or thickens so the fan starts to actually drive and pull air through the radiator. When not hot the fan just free wheels saving a little power, fuel and noise. When the viscous fails it free wheels even when the engine gets hot and does not pull air through.

With a fixed fan, it is operating all the time pulling air through (a plus) but for most of the driving we do a fan is not actually needed as the air flow through the radiator is enough (exceptions - traffic, 4wding, sand etc). So to drive a fixed fan energy is required from the engine and it can be noisy.

Long shaft usually means the shaft is longer tham normal and is of soft metal so it can be cut or easily machined to suit various different models in that vehicle/ engine range.
From my own experience and other information I have the 101 visous coupling usually fails locked up.
I replaced mine and it made alot of difference to cabin engine noise and a slight decrease in fuel burn.
