AAK77 - Diaphragm for Simms injection pump used on the 3.4 BMC engine.
Diaphragm is fitted to pump no SPE4A75S364 and SPE4A75S619
Fitted to the following tractors:
Nuffield 4DM, Universal Four
Please note that this is different to the diaphragm for the truck engine and must not be confused with the ribbed diapgragm (see part number 37H1247). This diapgragm, AAK77, is for the tractor engines, but we offer the truck version because some tractors have been fitted with alternative engines over time. It is important to get the correct diaphragm for your injection pump so that is governs correctly. If you are unsure please contact us.Â
