101 FC fan coupling...?

**tankradio2** · 9th October 2008, 01:42 PM

Some time ago the viscous coupling for the fan on my 101 Ambulance failed. I tried to source a replacement here in OZ but I could have bought a nice series 2A for the cost of the part.

I chose to drill and pin the coupling and make a 'hard drive' and it solved the overheating problem instantly.

Does anyone know of a suitable/affordable replacement for the 101 part as I am aware of the slight loss of power now from the modification.

Is there any reason I can't use the viscous coupling from a series 3 six or a range rover 8 ?

Cheers

I have a spare non functioning one as I recently replaced mine.
The new one came with my machine.
I will measure up the size of the old one and we will see if any thing else fits

G'day All, I have one off a 4cyl diesel (Series 3) also I was led to believe that some of the ford falcons were the same cheers Dennis

Surely the VC off any Rover V8 will fit - but then I do not know

Thanks for the replies. I am aware that the 101 part number differs from all other Landrover/Rangerover part numbers according to my parts book but was interested to hear if anyone had successfully substituted one from another rover.

I run numerous series 2A and series 3 rovers and have a spare coupling from a 2.6 lying in my parts shed which I thought of throwing into the FC...

Phil - you are right - I just checked my parts book and it does indicate that as of 1976 it is unique to the 101 - as is the fan itself. I would have thought that they would have just used a range rover fan and VC - I guess there must have been a reason.

For my benefit - what were the symptoms of failure - the fan not driving or does it completely lock up - or what. I wouldn't have a clue what to look for - my fan turns under all conditions so I guess it is OK.

Good luck with the mod if you end up doing it.

Mine sort of locked up by itself...........internal bearing locked.
I ownly found it by trying to spin the fan one day while playing around in the engine bay.

I just tryed turning my fan with the engine off and engine cold- it doesn't move so I assume it has locked up and doesn't work.

Garry you sound just like the right man to find a modern bolt on replacement.
My guess would to be trying a range rover visous coupling with the fan as well or to use two electric fans.
