Hi are the series one and series two 180 oil pumps the same one on ebay and was wondering if it will fit my 3c.

Series two pumps are higher volume (wider gears) they can be directly retro fitted to the earlier motors.

there seems to be some doubt over oil pump gear width, the only series 11's and RGS pumps that I have seen, have all been 10mm wide, someone did post that RGS pumps are 9mmm wide, which I think is wrong, anyone? although of course an RGS can be fitted with 9mmm wide oil pump gear

The only thing I found when fitting a wider gear to an early engine was the gear overhangs the central boss ( see pics first is the 7mm gear next a 9mm ) the longer centre is available but I think it's a press fit in the cases so I left mine well alone and just fitted the wider gear. Concensous was it should be OK .
