NOTE: The pressure lubricating oil pump can be mounted on the external of drilling pump
and driven by V-belt; or install the oil pump in the drilling pump driven by the gear ring.
When an internally mounted oil pump is used, the direction of pinion shaft rotation should
be as shown in Fig. 13; when reversing the pump, the inlet/outlet of lubricating pump
must be reversed.
2.2 Controlled Flow Splash System
The controlled flow splash lubrication system is the same on all F-Series pumps, regardless of the type
of oil pump drive provided for the pressure system. In the controlled flow splash system, the main
gear picks oil up from the reservoir, and when the teeth mesh with the pinion, the oil is displaced into
various troughs and compartments in the frame. With reference to Figure 15, the oil thrown into oil
trough (7) is directed through the oil tube (8) to the two pinion bearings.
Oil passage from the top of the crosshead guide compartment to the crosshead bearing is shown in
Figure 14; oil accumulates in the compartment over the crossheads. The oil runs through the nipple (1)
into the crosshead retainer to the oil passages (5) and on to the crosshead pin bearing. As noted, the
duplicate set of oil passages (5) in the crosshead pin permits the crosshead pins to be rotated without
having to give attention to hole alignment. This permits the installation of crosshead pins from either
direction.
