My new (to me) Cat D6C

Like the title says, I have a Cat D6C, Not sure of much else about it other than it has the turboed engine, I believe it is around a 1970 model year. My questions are lube related.
Engine oil capacity
Transmission oil capacity and recommended viscosity It has the 3 forward/3 reverse shuttle shift.
Final drive fluid capacity and recommended Viscosity

Serial# on the tag under the instrument panel RS is 76A5579 if that helps
Thanks for any help you can offer with my needs!
My Cat parts dealer wasn't a lot of help other than filter numbers.
 
usually the parts manual has the capacitys listed in the back of the manual
the operation and maintenance manual has the recommended viscosity's
 
Thank you, it's tough to nail down some things about these older machines. I did find a tag with much info about the things I asked for, and Cat had all the filter #'s and filters I need.
 
Thank you, The machine was purchased without any manuals, however I did find the info on the tractor after some cleaning of the Spec diagram. It tells me the capacities and recommended oils/lubes for my machine. I will attempt to find a service and tech manual for the machine soon. Having the year should make that a bit easier. I believe the engine to be a D333C like I stated in my OP it does have a turbo and If what I have found from other internet sources is accurate the D333C was the updated model of the original D333 and was only used a short time before Cat rebranded it (along with more updates) the 3306. Which all D6 models used after that change over. I have a vague history of the machines last 10 years or so but the owner passed away and the family was liquidating some of his assets, this being one... so I don't have a lot of first hand info about it. However the machine was not worked much and maintained well while the gentleman had it, that much I do know. That being said it IS a 54 your old machine and I will probably be a frequent user of this site with many questions as time goes by. Thanks Again.
 
manuals come up on ebay a lot--make sure the manuals cover your serial # range as Cat continuously made upgrades and they were serial# specific--not year
 
As I remember back in the day there were only two grades of oil used in the D6, HD30 series 3 engine oil every where except the hydraulics which took HD10, due to the ever recurring final drive failure that plagued all Cats of that era most people took it upon themselves to use gear oil in the final drives in the hope it would reduce the slap in the poorly engineered gears that the hardness was very shallow and wore off after a few years service causing the teeth to pick up and fail, the capacity of the components is usually quoted from when they are dry, I have scribbled in my notebook Engine 26Lts, Trans 64Lts and finals 15Lts, good luck with your machine, great machine no computers or other crap on them, you will be well happy with it.

Thanks, I don't plan on working it like a new machine but I will be using it each summer on my bigger jobs, land clearing mostly.
 
I have another D6C drain and fill question this one about the torque divider, My manual says to drain it via the plug on the bottom when doing the fluid change which i did....but it doesn't say anything about refilling and it is separate from the transmission so how do I fill it and how much does it hold? My service and lube manual doesn't mention refilling this section??? I did see the plug on the top right side of that housing behind the hydraulic pump which looks like the fill plug is this it? but doesn't have any way to know how much if any oil is in it. Thanks for any help here, I hope I've explained this so it's understandable.
 
My mistake, the filler plug I mention on the right side of the bell housing/torque diverter housing is behind the starter not the hydraulic pump. Thanks.
