Hallo All
Can anybody help me pls. I have inherited a lovely Ruston from my uncle who past on.
He was busy restoring it after he relocated it to his garden on the farm, from the river where it was driving a water pump for irrigation back in the 1960 s when his Dad bought the farm.
The project went very well until he wanted to start it. He discovered that the injector would not give a spray like it shoed or give a crack (like He called it).
Anyway he gave up and the injector went traveling true S.A. for help and it returned with the same problem.
The machine is very neat under a roof with a Lister for the compressor and all that's needed.
I told his children and grand children that I would start it on the farm before I move it to my farm 400km away.(I think this was a bad idea, but he worked so hard on it and none off he s children ever has seen it running. So I am going to try and do it out off respect for he s family.
Ok so this is what I have. A silver plate on the Ruston that reads: Size 7 Class H, No.148807 and a golden plate that reads: RUSTON and HORNSBY ltd, NO.B273,Plates 5/16 thick, water test 33 atmospheres 500 lbs. per square inch., working pressure 13 atmospheres 200 lbs. per square inch. Lincoln England. AND LAST :Date off test 9.1.28
Any help will be a big thank you. Regards Rikus

If you are in RSA,  try and contact Andy Selfe who trained at CAV  in the UK  on these injectors and fuel pumps. He is in Western Cape and well known there for diesel expertise. I have made him aware of your problem.
