Hydraulic System Maintenance
Hydraulic Gear Pump System
The T
OP
S
ELECT
™ is equipped with a gear type hydraulic pump (see Figure 7
12). With this type of
pump, all functions on the truck require the engine to run at idle except for the body hoist and for the
Maximizer system (see Figure 7
13) if the unit is so equipped. In fact, the engine needs to run at
1500 RPM to make the Maximizer move rearwards/forwards and to make the body hoist move
upwards. The main pressure setting is 2000 psi for a unit with a standard body and 2300 psi for a unit
with a long body.
The pump is part of a hot-shift PTO/pump system and is connected to the truck’s transmission via a
PTO unit. The pump provides automatic clutching at any time.
