Chevron TMGL Premium is a black, adhesive, semi-fluid grease specifically designed for lubrication of traction motor gear cases of diesel-electric locomotives.
Where to buy ›Delivering value for you
High film strength and EP additive package protects heavily loaded gears from wear and scuffing. Good low temperature fluidity offers effective lubrication under cold startup conditions.
Excellent oxidation resistance minimizes thickening in high temperature service while high base oil viscosity and adhesiveness minimize the tendency to leak from the gear case.
Effective corrosion inhibitors protect gear components from rusting in wet conditions.
Applications
Chevron TMGL Premium is recommended for:
• Traction motor gear cases (incorporating appropriate seal designs) where semi-fluid grease-type lubricants are specified.
• Older non-sealed traction motor designs that normally use heavy residual-type gear lubricants,where the higher leakage rate that may result is acceptable.
• Slow to medium speed industrial gear applications where an EP semi-fluid grease is specified.
