back into the crankcase just prior to starting.
Transmission, Converter And Power Steering Oil
Use Case TCH Oil
Hydraulic System Oil
It is recommended that Case TCH Oil be used. An alternate oil may be used. It must
:>e a heavy duty oil that meets American Petroleum Institute Service Designation MS or
DG. For temperatures above 32° F. use SAE l0W. For temperatures below 32° F. use SAE
5W. If SAE 5W is not available, a Dexron type oil may be used.
