Changing the diaphragm s
Remove the diaphragm cover 4 (Fig 6) after removing the valve cover.
The diaphragm 5 (Fig 6) may then be changed. If fluids have reached
the crankcase, re-grease the pump thoroughly. Also make sure the
drain hole at the bottom of the pump is not blocked. Use the following
torque chart when re-tightening bolts:
Diaphragm Bolt - 18.5 Ft/Lbs
Diaphragm Cover Bolts - 37 Ft/Lbs
Valve Cover Bolts (500) - 22 Ft/Lbs
Valve Cover Bolts (600) - 34 Ft/Lbs
7.6 Boom Maintenance
The 6’ FD boom breakaway should be
adjusted tightly enough so that the boom
stays securely in the upright (folded)
position during transport, yet loosely
enough that the boom easily swings back
if an obstacle is hit. Adjustment is made
by tightening or loosening the spring
tension bolt (Fig 7).
