3. CLUTCH LINING REPLACEMENT (FOR EM14320
CLUTCH ASSEMBLY ONLY)
A. Remove worn out lining and rivets. Check clutch springs
and flyweights for wear.
B. Cut 1/8” off of each end of clutch lining. Slide lining into place.
Insert one rivet into clutch lining hole. (Make sure rivet goes
from inside out.) Wedge a flathead screwdriver between clutch
flyweight and rivet head. Adjust screwdriver so that the rivet
sticks out from the clutch housing approximately 1/8 of an inch.
With a flat punch, pen the ends on the rivet so that it locks in
place with the clutch housing. Repeat this procedure for all
remaining clutch rivets.
PREVENTIVE MAINTENANCE
It is extremely important to maintain this pump due to
the highly abrasive nature of concrete material.
Mayco recommends checking after every 8 hours of operation.
1. Engine; Refer to engine owner’s manual.
2. Inspect all drive components for loose or worn bolts.
3. Drive belt/chain should be checked to remove all slack. Refer
to adjustment procedure.
4. Always carry extra “O” rings.
5. Keep entire pump clean of concrete to prevent build-up.
6. Always grease all fittings daily. Use only premium grade
grease. *Note: Over greasing will not damage machine.
