Does anyone have a part number or supplier of the copper and aluminum crush washers used on the perkins diesel injection pump? They are on the banjo bolts.

thanks in advance

Injection line banjo bolts used copper, but now are mild steel from CAV/Lucas/Delphi. Part# 5936 332C. DO NOT use aluminum, especially on Stanadyne/RoosaMaster pumps.

There were 2 aluminum washers on each banjo bolt and 1 copper on the straight fitting. I am not sure of the pump brand but it is the original to the tractor. Early MF 135 Perkins Diesel.

CAV DPA pumps did use copper gaskets on some pumps, but never aluminum at the injector outlet ports. I would suspect the aluminum washers were put on in the field. If they crush too much there is a risk of the bolt bottoming out in the head, causing the rotor to seize, that's why aluminum should not be used. Stanadyne/RoosaMaster pumps are very prone to this as the bolts are longer. If just one washer is left off the head will seize, locking the rotor and breaking the drive shaft.
