Do i use sae 30 for transmission ?
As always it is best to include a full S/N to be sure you are getting the correct information or at the least a prefix of the S/N. Just an example, here is what comes up when I search on SIS for D3C: TRACK-TYPE TRACTOR Model Prefix D3C TRACK-TYPE TRACTOR 1PJ D3C TRACK-TYPE TRACTOR 3RF D3C TRACK-TYPE TRACTOR 5KG D3C TRACK-TYPE TRACTOR 6PF D3C TRACK-TYPE TRACTOR 7JF D3C TRACK-TYPE TRACTOR 8BF D3C II TRACK-TYPE TRACTOR 4HJ D3C II TRACK-TYPE TRACTOR 5CJ D3C II TRACK-TYPE TRACTOR 5ZG D3C II TRACK-TYPE TRACTOR 7JG D3C II TRACK-TYPE TRACTOR 8DG D3C III TRACK-TYPE TRACTOR 4KS D3C III TRACK-TYPE TRACTOR 4TS D3C III TRACK-TYPE TRACTOR 5GS D3C III TRACK-TYPE TRACTOR 6SL D3C III TRACK-TYPE TRACTOR 7XL D3C III TRACK-TYPE TRACTOR 9TS And each Prefix could have a few different versions depending on the S/N range. But I picked just one random D3C and the attached file shows lube chart for at least some of the D3C machines.
