Try Jim, send a PM to russellrovers as he could supply one or at least may be able to give you the dimensions.

Just found one in an old gasket set. 1/4" cord diameter, 1" OD (so about 1/2" ID)

There is a lot of flash on the mould line so it looks like low volume production rather than from an O-ring supplier.

Hope this helps.

Scott's old rubber do them as well. Please note that there is a cooper ring that is fitted inside the o-ring. Look at the series 1 water pump bits on the Dingocroft website.

That's interesting, and might explain why mine leaks. I knew the Series 1 had the copper 'collar' but not the 6. Would it be the same dimensions on both engines?

I will check my parts books and let you know. A bit of RTV rubber outside the o-ring never hurt as well before you bolt the thermostat housing or water pump back on!

You need an RTC1975 o-ring and a 9197 washer (ring). That should help fix things!

My parts books show a split bush (metal) part number 564164 up to suffix B engines. This pushes into the water pump and sticks out for the O-ring to locate on. Not something you might normally replace/remove.
No need for a copper ring fitted inside the O-ring.

A later picture shows a spigot on the pump body but does not list p/n 564164 as a separate item

Picture below is the motor from my FFR, you can see the O-ring sitting on the spigot on the pump (you can just see a split so it must be p/n 564164)

Thanks Colin - water pump in your picture looks same as mine, except the spigot/bush on mine seems to be damaged, which may be letting water escape. Not enough to be noticeable in the tank, but always a brown stain from that joint. Will search the usual suppliers tonsee if anyone carries that part.

Thanks again

Roger,

I got one from 4 Wheel Drives in Blackburn the other day (sorry, I'm keeping it for my spare motor). Last one, looked genuine by the packet.

I tried a couple of the UK suppliers and that part number didn't come up at all. I'm thinking it may have became part of the waterpump that's why it wasn't listed against the later pump in the parts manual.
Might be worth trying a LR dealer, may still be on their system.

It's basically a spring steel tube (almost an oversize roll pin). approx 14.2mm OD, 15.82mm long, 0.2mm thick steel.
