I have plenty of experience with the exception of dozers, was recently asked to change the ring and pinion on this cat but can not find any technical info or proceedures, any help and advise would be great. Customer has it exposed.
I took a look in SIS and just like I thought there are around a couple dozen different S/N Prefixes and who knows how many variations in each one. The more info you can give the better chance of getting an answer that will actually help you. Best thing is a full S/N along with any major options that the machine may have on it.
No problem, 7JG00086 is the serial number.
I've sent you a private message/start conversation reply to it with an email address I can send an attachment to of a nine page description of the job.
