John Morrison Posted September 30, 2020 Report Share Posted September 30, 2020 Hi all, On the modified rear main oil seal, the one with the ground off scroll and twin half moon aluminium seal carriers, does any one have the replacement seal number? and i sthere any upgraded seal now avaiable? I have the thought that someone mentioned using a double lipped seal? Cheers, John. Quote Link to post Share on other sites
Ian Vincent Posted September 30, 2020 Report Share Posted September 30, 2020 Revington sell the seal on its own but I can’t say whether or not it is a double lipped one. Rgds Ian Quote Link to post Share on other sites
RogerH Posted September 30, 2020 Report Share Posted September 30, 2020 (edited) Hi John, I'm sure Iain posted just recently that the supplied seal is either too big or too small (too small I think) I think he mentioned what the new seal is.

iain Posted October 1, 2020 Report Share Posted October 1, 2020 Hi John its complicated by various offerings being made over the years and most having limitations , even errors in their manufacture or recommendations for the crank regrind dimensions. Most points are in the post Roger has linked above. (Many thanks Roger I can never find stuff when I want to!) Iain Quote Link to post Share on other sites
John Morrison Posted October 1, 2020 Author Report Share Posted October 1, 2020 Cheers Guys, we have a group member sorting a TR4A, and he is ex Rolls Royce, and has very high standards! John. Quote Link to post Share on other sites
RogerH Posted October 1, 2020 Report Share Posted October 1, 2020 Hi John, just to clarify - There is the older modification where the crank seal surface is turned down and the LandRover lip seal is fitted (normal single lip) The link in my post above explains. There is the Christian Marx seal. The crank is NOT machined. It comes with its own seal carrier and appears to work well. The there is the Austrailian 'O'ring method -http://www.tr-register.com.au/Files/technical/scrollseal.htm Double lip seals do not necessarily have double the oil sealing power. The extra seal is to stop dust (usually) Roger Quote Link to post Share on other sites
Rob Salisbury Posted October 1, 2020 Report Share Posted October 1, 2020 Hi, If it's any help to anyone around 6 years ago I had a new Pheonix Crank ready to instal and decided to use Revington's lip seal conversion, I gave the crank and Revington's instructions to Classic and Modern Engines (in Bracknel) and they machined it for me, I recently had the engine out and looked at the rear seal, not a single drop of oil was visible or any other sign of leakage, ......... a result and a big plus for Revington's seal.

RogerH Posted October 1, 2020 Report Share Posted October 1, 2020 Hi Rob, that is good news. My TR4 had the crank ground at C&M. Not sure iof the seal came form Revingtons but very possibly as I get a fair bit from them. Roger Roger Quote Link to post Share on other sites
John Morrison Posted October 27, 2020 Author Report Share Posted October 27, 2020 Following on from earlier questions, the replacement oil seal from Rimmers, comes with the following T Shaped Rubber peices. Not seen these before, do they replace the cotton wadding packed at the rear bearing cap? or do they have another use? John. Quote Link to post Share on other sites

That looks like the Land Rover rear seal kit, which the TR and Healey kit is based on. That does not mean the diameter is correct for TR - You would need to measure!!! link to sellers of the Land Rover seal kit https://www.ebay.co.uk/itm/Bearmach-Land-Rover-Series-3-2-25-Petrol-and-Diesel-Rear-Crank-Oil-Seal-Kit-/222146189089 https://www.ebay.co.uk/itm/Land-Rover-Series-3-2-25-Petrol-and-Diesel-Rear-Crank-Oil-seal-Kit-542492-x1-/221157247004 Peter W Quote Link to post Share on other sites
iain Posted October 27, 2020 Report Share Posted October 27, 2020 (edited) You might find it useful to refer to this Instruction leaflet that comes with the Revington kit, it explains why so many seals fail and how this can be avoided. https://www.revingtontr.com/productimages/docs/FI008 REAR MAIN BEARING OIL SEAL KIT RTR1026 issue 4.pdf Mine failed on and off for 40 years......wrong crank dimensions and poor housings.

Ian Vincent Posted October 27, 2020 Report Share Posted October 27, 2020 Having just installed a Revington rear seal I can confirm that no T pieces are required. The kit consists of two machined aluminium crescents, a few washers, a pack of grease and the seal itself. The trickiest part of the installation is stopping the split in the seal opening up when you are pressing it down into the housing. It is a tight fit. And you are trying to deal with a heavy crankshaft at the same time. Rgds Ian Quote Link to post Share on other sites
