Omega General Help / R28 gearstick circlip???

« on: 01 February 2011, 20:49:43 »

Hi have now got my r28 box fitted to redtop engine, i need to know what the part is needed to stop the gearstick base popping out of its seat. i guess its some kind of clip/circlip to hold the round white seat? any help or part number would be great cheers in advance

this seems to be the solution as i have been to calder clutch and they made me one up for £40 clutch part no 1907 for anyone else in the future, but not finished yet i need to find a 20mm spacer to compensate for losing the dual mass flywheel unless anyone knows a solution have had one idea sent to weld on a transit di bearing but problem is omega one is a plastic case

hi have just got all the bits together and tried assembling, the r28 clutch plate is 9.5" where the redtop is 9" and the splines are different  r28 has bigger and less splines. any suggestions? on a lighter note the spigot bearing fits [smiley=2vrolijk_08.gif]

I suspect you may need the 2.5V6 clutch setup which from memory is smaller.

Check the Borg and Beck or similar clucth sites (e.g. LUK) for info

hi the pressure plate and basket on the new r28 clutch are the same fitting etc so i presume the release bearing will still work, not sure what you mean by right height? in theory if i could graft the splines from the r28 plate to redtop plate it would be fine, but after reading various forums and advice was told it would be a simple bolt on job

thanks again have found another forum thread giving the needle bearing part no. so that is sorted can you advise on what flywheel and clutch to use?

R28 will fit straight on a 2.0 XE.

make sure the spigot bearing is installed in the end of the crank, and whatever flywheel combination you're using has the same height as the gearbox is expecting.

you must, however, use an R28 from Omega and NOT from Carlton / Senator.

thanks does that mean the r28 will fit straight on with the shaft etc and no mods as i have sourced a box?

"in general there are two types of box that you're looking at here, both are Getrag 240.

the R25 is a standard box, more often than not fitted with the small output "donut".

the R28 is a stronger version of the same, usually with the larger output "donut". The extra strength comes, I think, from shot-peened gears.

either will be ok for your application - it's vehicle weight and traction that kills gearboxes."
