Jon Ward Posted July 19, 2009 Share Posted July 19, 2009 I've done a search, but I want to make sure that I'm covered so that I can hopefully get the engine in and out in a day. The problem occured during the Oulton Park Club track day. I can select all gears when the engine isn't running, but none of the gears when the engine is running. If I start the car in gear, the clutch travel 'seems' shorter than usual and the bite point is immediate. The clutch feels very heavy, but the cable seems OK. It's a bog standard '99 K Series SLR. 1. Any ideas what it could be? 2. What parts should I collect to get the job done in a day? 3. Anything else I should do while the engine is out? Thanks in advance, Jon Link to comment Share on other sites More sharing options...
andy_h Posted July 19, 2009 Share Posted July 19, 2009 when you start the engine with it in gear, can you then deselect the gear? if not then it sounds like a problem I had on a track day when the selector broke inside my gearbox. If engine out I'd check/replace the CRB.

Adrian Williams Posted July 19, 2009 Share Posted July 19, 2009 Jon, sounds like you've got a clutch problem of some sort, could be pressure plate, crb or fork. You ought to change the crb while the engine's out anyway so that's a given, pressure plate comes with the friction plate as a set and there are two types of fork depending on wet or dry sump. With any luck you'll be able to diagnose a bendy fork with the engine still in the car to save on the amount of parts you'll have to buy and possibly not use if you want to do the whole thing in a day.

Area Representative Richard Price Posted July 20, 2009 Area Representative Share Posted July 20, 2009 With any luck you'll be able to diagnose a bendy fork with the engine still in the car.... Why do the dry sump clutch release arms bend? Surely that it indicates that something else is also wrong? What are the normal failure modes of the clutch its self? Surely, if it is worn out it will slip. Do the plates break up which then causes them to drag? How likely is it that the spigot bearing has failed?

shn7 Posted July 20, 2009 Share Posted July 20, 2009 My money's on it being CRB failure. Did mine a few weeks ago. Much the same symptoms you describe. Took it all apart to find the CRB had collapsed into several pieces. £20 delivered from CC and a few hours with friends taking things apart and putting it all back together again. Steve.

Mark Durrant Posted July 20, 2009 Share Posted July 20, 2009 Jon I suspect the clutch fork if you have the Caterham dry sump system and have seen a few of these fail. It could possibly be the CRB or the pressure plate however, you cannot tell for sure until you get the engine out. Good luck and I hope to see you at Curborough Richard The clutch forks fracture and when you see how they are made in comparision to the wet sump fork you will understand why. I think it is unlikely to be the spigot bearing. Mark D Link to comment Share on other sites More sharing options...
shn7 Posted July 20, 2009 Share Posted July 20, 2009 I'd originally expected to find my clutch fork bent or broken from the way it failed and comments like Mark's but it was CRB. Not saying Mark is wrong, as he says you won't know until you take it all apart. If you're looking to order parts ahead of removal and want to minimise cost I would only order the CRB as that ought to be replace regardless. If you're lucky that will be all you need and can get on with putting it all back together. Steve.

Jon Ward Posted July 23, 2009 Author Share Posted July 23, 2009 Thanks for the advice guys . I'm going to order the following, and hope for good news: - Spigot bearing - Adaptor sleeve - Clutch release bearing Best regards, Jon Link to comment Share on other sites More sharing options...

Area Representative Richard Price Posted September 9, 2009 Area Representative Share Posted September 9, 2009 Anthony, Jon's car is running again. See here We finally put it back together on Monday this week. Jon has had additional welding done to prevent it cracking in the same place again.
