[CABRIO]

Hello All,

I would like some help with a problem I have created for myself.

I have a 1986 1135 connoisseur cruiser with a sliding roof.

It has BMC / Thornycroft 154 diesel engine, with a Johnson Raw water pump F5B-9002 / 10-24119-2 .

The bearings needed to be changed in the pump so I removed it and found that the pump shaft was in two pieces and joined in the middle and held together by a pin.The shaft needed to be pulled apart so that the bearings could be removed and replaced. One half is the shaft that comes with the pump and the other is an Add On / modification by BMC or Thornycroft spiral / twisted part that when fitted extends into the engine and is driven by moving engine parts( forgive my lack of knowledge for technical terms). 

I could not separate and after apply heat ( probably to much ) and force, managed to turn it slightly then it wouldn't budge. In the end to ( after believing it was all part of the pump and I would get a new one with a replacement part) decided to angle grind apart and see if it did need to be turned apart and was threaded as I thought.

Sadly not, and know, I have a problem trying to source a replacement part for the pump. The pump I am fairly confident I can replace but I cannot find the modification /spiral twisted part, that was made by BMC/ Thornycroft that needs to be added to the pump crank.

Has anyone had a similar problem and know where to but the part I need or where I may possibly get it made. 

Any help would be appreciated,

Is there not a circlip that needs to be removed before the shaft will come out? 

Having googled your model number Im fairly certain I once replaced the seals in one of those and there was a circlip involved!
