My manuals don't tell me which oil to use for my One Seventy. Can someone give me a reference or tell me what you use? Thanks.

Howdy Farrell,

Just got done changing oils this winter in my 1967 One Seventy. Oem manual says 24 qts for transmission and 26 qts for hydraulic system. Manual also says use Allis Chalmers special fluid! But after much consideration I put in trans/hydraulic oil in both. Hope this helps

Most any Universal TransDraulic oil has the Allis 821 spec listed, last I looked. It's all you need for both.
