Overview – MAIN BEARING COVER 206587-20 Series
Built to Cummins specifications, the MAIN BEARING COVER 206587-20 serves Cummins transmission and power-shift component mounting; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A main bearing cover that closes the main bearing housing on the transmission or power-shift assembly. It locates the bearing and seals the case, and its flatness and seal decide whether the unit weeps or runs clean.
Applicable Models & Applications
Fitted to Cummins transmission arrangements at the corresponding face. Match the cover outline, bolt pattern and seal type against your old part – main bearing covers for nearby positions differ in both shape and bore.
Maintenance & Replacement
Inspect the cover for distortion and deep scoring before refitting. A cover that has been pried off with a bar rarely sits flat again, and a warped cover weeps no matter how hard the bolts are pulled.
Prepare both sealing faces – clean, dry, free of old gasket – before the cover goes on. Gasket left in the case grooves is the usual reason a fresh seal still leaks.
Torque the bolts evenly in sequence. A cover drawn down on one side distorts the flange and the new seal cannot close the joint, so it weeps under load.
Keep common main bearing covers for your unit on the shelf. They are cheap, easily damaged in removal and exactly the part that is missing when a case needs to go back on today.

As a reference, the MAIN BEARING COVER 206587-20 is typically priced between USD 20 and USD 80 depending on configuration, lot size, and current exchange rates.
