inchoate Posted June 18, 2022 Share Posted June 18, 2022 I might be in the market for a pair of engine mounting rubbers for an S3 Caterham. Does anyone in the states stock these or do I need to go across the pond? Link to comment Share on other sites More sharing options...
MV8 Posted June 18, 2022 Share Posted June 18, 2022 I believe they are sourced from the jag xke. C18556 is a part number for the jag. 1 Link to comment Share on other sites More sharing options...
Croc Posted June 19, 2022 Share Posted June 19, 2022 Beachman Caterham or Rocky Mountain Caterham should have them. Link to comment Share on other sites More sharing options...

inchoate Posted June 28, 2022 Author Share Posted June 28, 2022 good call on Sevens & Elans. Chris was able to hook me up with motor mounts and he also was able to get another thing I've been having trouble finding. Link to comment Share on other sites More sharing options...
lotsats Posted July 2, 2022 Share Posted July 2, 2022 I need these mounts too, and look up the part numbers on the web sites for various auto parts stores in my area. O’Reilly Auto parts shows them as an item they can order at a cost of less than $10 each. Link to comment Share on other sites More sharing options...

MV8 Posted July 4, 2022 Share Posted July 4, 2022 C18556 for a '60s Jag XKE https://www.oreillyauto.com/detail/c/uro-parts/engines---transmissions/mounts/motor-mount/31470ece703c/uro-parts-engine-mount/uro0/c18556/v/a/15662/automotive-car-1967-jaguar-xke?q=motor+mount&pos=0 Link to comment Share on other sites More sharing options...
Sean Posted July 5, 2022 Share Posted July 5, 2022 The engine mounts on my Caterham seem to be a consumable item. So when I bought replacements, I bought about a half dozen, from Rock Auto. Uro P/N C18556 (as above). Current Rock Auto price showing as $6.61 USD. I'd be interested to try the Vibra-Technics improved version, available from Burton or Vibra-Technics, but I don't have the additional 3.5mm of under bonnet clearance to spare.

MV8 Posted July 5, 2022 Share Posted July 5, 2022 3.5mm is about the same thickness as a mens leather belt and the engine would likely rock that much under load (amazing to see how much engines move in cars strapped to a dyno). You could shave 1/8 off the bottom of the engine brackets and use a washer if you ever needed to go back to softer mounts. Less vibration with the original jag mounts. These are just higher durometer from the carbon powder mixed with the rubber. Have you considered a loose at idle, limit strap across the left jag mount to prevent too much movement yet still provided the normal NVH? Do heavier, more powerful xke jags have mount issues? I've not looked into that or what that group does about it. As rubber mounts age, they tend to harden (less movement-more vibe) and crack. I'd replace them if over 20 years old; especially at under $10/each. Link to comment Share on other sites More sharing options...
