MAYCO ST-45HRM CE PUMP — OPERATION & PARTS MANUAL — REV. #0 (02/23/04) — PAGE 45
4.0 ADJUSTABLE HEIGHT DRAW BARS
4.1 HEIGHT ADJUSTMENT/TIGHTENING JOINTS
the principle of the joints is steel pegs engaging with mating
dimples (Figures 44A and 44B), which can be seen between the
joint plates.
While securing the assemblies, the equipment should be “rocked”
as the joint pins are tightened to allow positive location.
When initially hand tight, they should be further tightened until
the next visible “R” pin hole lines up for the insertion of the pin.
For reference only, the actual torque figures if checked would be
approximately as follows:
■
TYPE A900 135-220 Nm
■
TYPE A1600 175-220 Nm
■
TYPE A2400 230-300 Nm
■
TYPE A3500 410-475 Nm
