Yes we do supply but better you don't need one. Ian Ashcroft ;)

Ian, I usually replace the oil pump and oil slinger/ ferrobestos bush every time I replace the 5th brgs, I agree about disassembling the pump, not a good idea:(

Timken are OE aren't they?

Hi the two R380 rear support brgs are RHP, I would replace both, the oil ring is usually Carbon in the R380 and is prone to cracking, don't know progress but do know Dave is working on a replacement made from 'fibre?' not exactly sure what matl. Regards Ian :)

we are making the FTC4991 oil feed rings from a laminate called 'Tufnol whale', the blanks are water cut then CNC turned,

Thanks Dave, sounds like an endangered species.....:p

Sorry I was also wrong, I have been using RHP, not Timken.

this thread got me thinking, this mainshaft rear support bearing oftern fails, can we get a bigger one in there ?

this arrived today from SKF, ID is the same, OD and thickness are bigger but I think we can make it fit with a little machining in the ali housing, new on the left, genuine on the right :

this may be a useful mod for those that run a tuned TD5 or tow a lot or have a heavy overlander,

Dave, a quick Q.

On those g/boxe that come through with that bearing failed, how many do you think have been running ATF vs how many running an MTF ?
Or is it purely an overload failure ?

usually MTF94,

typically from a tuned TD5 or 2.8 TGV

Dave

Great idea Dave, keep us posted!:)
