Cub Lo-Boy 154 Transmission/Hydraulic

Postby doyle » Thu Jul 07, 2016 7:42 pm

To me it looks like the transmission and hydraulic system use the same oil. Am I correct? If this is correct then why does it have two different oil types specified. Transmission is spec'd IH-HY-Tran oil and Hydraulic is spec"d AW-48 some use 90W. If anyone can help with this I would truly appreciate it.

The hydraulic reservoir, hydraulic system, and transmission/differential utilize Hy-Tran or equivalent hydraulic fluid.
Hydraulic is spec"d AW-48 some use 90W.
Just checked my 154's Operator's Manual and could not find the referenced specifications. If AW-48 is an oil weight, it's above the weight of most hydraulic fluids. 90W is for sure to high, generally used in finals and transmissions.
I have an excuse. CRS.

Depending on the year of the tractor, and the manual provided, the manual could reference both the standard Cub, and the number series lo-boy. In which case, the Cub has a separate differential and hydraulic fluid reservoir (touch control unit), where the number series lo-boy tractors use the differential as the hydraulic system reservoir. The late model Farmall Cubs, built from 1969 to 1979 were built at the same time as the number series Lo boys (154, 185, 184), but the owner's manuals were the same for both tractors as 95% of the components are the same. Prior to 1969, and the number series tractors, the old style lo-boy tractors had nearly 100% of the same components as the standard Cub, with a separate touch control (hydraulic) unit, and the only difference being the shorter front steering spindles, and a few sheet metal differences.
