In 2005 my radius arms suddenly both developed play, so i went to minispeed near brooklands and swapped them for exchange units. Some time later i realised they had roller bearings both sides, didnt bother me at the time thought it was a good upgrade! Some 6 years of use and probably the wrong grease used (moly - i liked it) the needle rollers had worn totally flat! I pressed new bearings into them but was never that happy and the o/s arm seems bent.
So i replaced the bent one today with a brand new minispares one. I looked inside and i'm positive the grease tube was inserted as the top of the bearing rollers were flush with the bore, although it wasn't white plastic like what you get in the kit. You would never get a tube in anyway with the bearings fitted.
How many grease pumps from a grease gun does it take to fill it so grease pushes out the little rubber seals? i'm up to 50 pumps already...
