Figure 8: Power End Disassembly
9. Remove blind side bearing housing (7), hex head cap screws (19) and shims (9).
Remove the drive side bearing housing (8), hex head cap screws (19) and shims (9).
Note that the bearing cups (11) and crankshaft oil seal (27) will remain attached to the
bearing housing (8). It may be necessary to tap on the housing with a rubber mallet to
free it from the power frame (1) after the hex head cap screws (19) have been removed.
If that is not adequate, tapped jack screw holes which are the same size as the cap screws
(19) holding the housings in place have been provided in each bearing housing to help
remove stuck housings.
