Englishmaninwales Posted January 28, 2016 Share Posted January 28, 2016 For info. This may already be in the archives.The bearing in the auxillary drive tensioner for the dry sump scavenge pump does wear and I'm aware of at least one failure with an expensive engine rebuild bill. I have replaced the bearing or whole tensioner unit every 3 years or so.The complete tensioner is available from CES UK factors in the North West and North Wales - see www.cesuk.com for contact detail. However they are expensive at £70. They have a plastic tensioner wheel, but I have found this fine in service. CES part number 534016810.If you have the original CC/Titan supplied aluminium tensioner wheel it is possible to replace the bearing (I have not been able to remove the bearing in the plastic wheel without destroying it). This bearing is 6203 LHA made by NTN dimensions 17*40*12 mm and is available from Simply Bearings 01942269837 or www.simplybearings.co.uk at £27.50. Note the LHA spec which is rubber sealed with high temperature grease rather than lower spec 6203 open or metal shielded bearings.Hope this is helpful.MalcolmEdited to add - the automatic spring loaded tensioner with the later gold scavenge pump.

TomB Posted January 28, 2016 Share Posted January 28, 2016 Crap, mine is the original 1996 one! Link to comment Share on other sites More sharing options...
Englishmaninwales Posted January 28, 2016 Author Share Posted January 28, 2016 TomTom to clarify, I'm referring to the automatic tensioner associated with the gold pump - I think the purple pump (I recall yours is a purple pump) has a manual tensioner - may or may not be different.

TomB Posted January 28, 2016 Share Posted January 28, 2016 Ah, mine is a manual tensioner with purple pump. Probably worth thinking about a new one when I next change the belt. Any idea of the part numbers for the purple pump tensioner? Link to comment Share on other sites More sharing options...
Englishmaninwales Posted January 29, 2016 Author Share Posted January 29, 2016 No sorry Tom. The later tensioner I'm referring to was a Rover item, so might be worth hunting around to find out what car it came off, or better still take it off and look at the identification number on the bearing.

Rob Walker Posted January 30, 2016 Share Posted January 30, 2016 Malcom, Yes its possible to replace the bearing from the alloy tensioner pulley. THe alloy pulley was an R500 upgraded part made by Titan. Gently heat the pulley and tap on a hard surface the bearing should drop out, the bearing should have identifying numbers stamped on it ebay is your friend for a replacement.
