Customer Question

I am working on a Perkins 4.108 on which the cooling pump is not working. I have replaced the impeller but have found that there is no drive to the pump.
Having removed the pump I find that the connection between the pump and the drive from the fuel pump is broken though I can not see how it was supposed to be connected. The Manual I have does only shows a breakdown of the pump ending with a notch at the end. This notch connects with a bar on a short cylindrical piece of steel with a flush end on the drive from the pump.
Has anybody any idea how the connection is made?

Is this a marine pump? Do you have pictures you could attach using the paperclip icon above the typing bar? Coupling may just be a fiber cross and two cuts mate with pump, and to mate with drive. It would just be installed with pup, and not connected to anything,

I am afraid this does not mean anything much to me. Fibre cross and two cuts, pup?
I have three pics but the connection on board is bad tonight, i'll try and send them tomorrow.
