Gear Oil
Manitowoc acknowledges that there may be boom hoist lubricants available
that are as good as, or better than, those we have approved below. However, we
have not verified the results of using those lubricants in the boom hoists on our
cranes. You are urged to consult your oil supplier before using a boom hoist
lubricant that is not approved by Manitowoc. If your oil supplier warrants that
the lubricant is in fact equivalent to the our approved lubricant and will provide
the required lubrication, then your crane warranty will not be affected.
Gear oil must meet or exceed API Service Classification GL-5 and
MIL-L-2105D.
Transmission and
Chain Case Oil
Use any 10W-30 oil that meets or exceeds the requirements of API Service
Classification CG-4, CF-4, CF-2, CF, SH and those of MIL-L-2104F.
Controlled Torque
Converter Oil
Use any 10W oil that meets or exceeds the requirements of API Service
Classification CF, CF-2, CE, CD-II, CD, SH, SG and those of MIL-L-2104F
and MIL-L-46152D.
Hydraulic Oil
Use a quality brand hydraulic oil that contains oxidation, rust, and foam
inhibitors. Additionally, the oil used must have good thermal and hydrolytic
stability to prevent wear, erosion, and corrosion of internal parts.
