Are you asking me or telling me mate?? Not sure..But I have been given a part number and ordered one so if anyone needs it in the future to change the oil seal its supposed to be .The oil pump complete part number ? 74020-1 pump assy.
AS it would appear people on here seem to know a lot about the master 2500 I dont suppose anyone knows what the part number is for the Oil pump for the main tank Item number 74000-0 (79-897 in the hand book. page 9.
`Cheers Ronan. I thought thats what you meant.You asked for the part number for the oil pump, and then quoted a part number - Item 7400-0. I thought you wanted to know the part number of the complete assy. Anyway there is a company on ebay called mare equipment that sells Colchester lathe spares.
