PAGE 16 — MAYCO C30HDGA CONCRETE PUMP • OPERATION MANUAL — REV. #1 (09/09/19)

GENERAL INFORMATION

The pumping piston (Figure 3) is forcing the material past 

ball (B) and out to the nozzle, also seating ball A so that the 

material will not flow back to the hopper. This action also 

fills the compensating piston for the next stroke.
Figure 4 shows the relationship between the return spring,  

the compensator spring and the rocker arm to maintain a 

smooth performance. DO NOT tighten the bolt (Item 1) 

completely, the rod end must be able to move.

The return spring is installed to eliminate shock and stress 

between the cam roller and the cam weldment when 

the pump is in operation. If the return spring is removed 

or replaced for any reason, maintain the backing plate 

dimension (3-inches) as shown to produce proper pre-

loading  of the spring for a smooth performance.
