Oil Fill
Figure 7.46 depicts an early model pump and shows the
drain plug (item 2) and the sight gauge (item 3).
1. On units so equipped, install the glass sight gauge in its
proper position on the side of the pump. Tighten the sight
gauge to the torque value specified in the Torque Chart,
found on Figure 7.2 (Exploded View) at the beginning of
this chapter.
2. On units so equipped, install the 3/8” NPT oil drain plug
in its proper location. Tighten the oil drain plug to the
torque value specified in the Torque Chart, found on
Figure 7.2 (Exploded View) at the beginning of this
chapter.
3. Insert a funnel into the Oil Fill/Breather cap threaded
opening at top of the pump crankcase. Add the amount
and type of oil recommended in the table in Part 2 of the
Common Pump Components section, earlier in this
manual. On units so equipped, the oil level should reach
the center of the sight gauge.
4. When pump has been properly serviced with the
recommended oil, install and tighten the Oil Fill/Breather
cap to the torque value specified in the Torque Chart,
found on Figure 7.2 (Exploded View) at the beginning of
this chapter.
5. If so equipped, install the 1/8” NPT pipe plug into its
threaded opening on the pump head. Tighten the plug to
the torque value specified in the Torque Chart, found on
Figure 7.2 (Exploded View) at the beginning of this
chapter.
