Gear Reduction Oil (Transmission)
1.Remove the transmission oil level plug (Figure 6). If oil begins to seep out as the plug is being removed, then it can be assumed that the transmission oil is at the proper operating level.
2.If oil does not seep out as the oil level plug is being removed, then remove the transmission oil fill plug and fill with SAE 80/90 EP gear oil to the proper operating level. Transmission oil capacity is capacity is

Helpful Hints
The capacity of this diaphragm pump will vary greatly depending on the height of the suction lift and length of the discharge hose. A discharge hose which is too small, long or high will cause the following:
■Excessive bulging of diaphragm on the down stroke.
■Valves closing with a lould snap.
■Rough operation.
■Engine overloads and slow downs.
■Reduced efficiency
