G'day. I am a farmer in Australia. I purchased a D7G a few years ago and I am just learning how to use it and drive it. Having great fun. I got a workshop manual with the Dozer. I have been reading many posts re D7G's and love it. I have learnt a lot. I am not a Mechanic but want to learn how to do almost everything myself. I have worked on my Diesel tractors for years. My machine does use engine oil, does use Trans oil, does use hydraulic oil. I don't use the dozer for long periods just 2 to 4 hours at at time. Over that time I may use about 3mm on the engine oil stick. 2mm on the trans oil stick. Not sure on the Hydraulic oil. I check the engine, trans and final drives while the engine is warm and idling. I empty about 250ml out of the Passengers side final drive and about 50ml out of the drivers side. is this normal. Should I be checking the final drives whilst the engine is idling. . I look forward to your replies. Buggo
Hi Buggo. Maybe post your serial number so everyone can answer your questions properly.
James. thanks for the reply. Serial number 65V3998 1981 model
Its not normal but common to lose transmission oil into the finals on a old girl we just drain them off once in a while and top off the transmission
The experts hopefully will pipe in here but I think the tranny and final drive oil is the same. 30W T0-4. I believe but will wait for others to verify. If your only using the machine occasionally I wouldn't worry about getting into it unless it gets a lot worse.
D7G's are apparently one of the easier Cat's to work on. Have heard an engine can be pulled in a couple hours compared to other models that take several hours. Hopefully you won't need to be pulling the engine out any time soon.
Thanks Mate.
Thanks Mate. Its a great machine. I am just learning but having great fun. Thanks Welder. I am also a welder "Boilermaker" by trade. I love my Cat. Easy to drive and easy to work on I think. . Buggo
Thanks James. I think they are the same. I will have to check. Buggo
