Jinma 254 injector washers

[ianburgess]

Hi
I have a Jinma 254 that suffered overheating resulting in a warped head. The water pump has been replaced and the head taken to an engineer to be machined. The engineer removed the injectors and lost the washers that fit between the injectors and head. I have contacted the nearest supplier and am waiting but hope to shave the two weeks between ordering and delivery even if they have them in stock. I may be able to source non genuine washers but need the size and material specifications.
Can anyone help please?
Cheers.

I have asked Jinma as well were main Australian parts supplier, but no answers yet. I have also looked through online parts diagrams but can't see any washer in that position. The parts diagrams refer to a Y385 engine number but my manufacturer plate calls it a KM385 BT. Does anyone know if that are the same thing, or even whether there I a washer at all? I maybe trying to source a rainbow unicorn.
Cheers.

Most likely soft copper crush washers. I would not guess the size, better take the injector to a diesel shop and match it. Wrong size or thickness can cause sealing problems.
