Inspect / Torque Bolts; Build Up & Wear Plates; Checking And Replacing Wear Plates - Stanley Labounty MDP Series Safety, Operation & Maintenance

INSPECT / TORQUE BOLTS

Inspect all bolts for damage. Check the torque of all bolts and replace any bolt that is damaged or has been re-torqued
more than once. Always use replacement bolts of the same size and class as the one removed. Unless otherwise
specified, use class 10.9 metric hex head cap screws, class 10.9 metric flat head cap screws and class 12.9 metric
socket head cap screws. When installing new bolts, ensure that the bolt is clean and dry.
Note: Some bolts have unique torque specifications. Refer to the parts manual.
Never use an inferior class fastener. Fastener failure
can cause damage, injury or death.

BUILD UP & WEAR PLATES
As the jaws become worn from use, the worn areas will need to be built up to prolong the life of the attachment. Some
areas of the jaw have wear plates that protect commonly worn surfaces and reduces the need to build up and hard-
surface.

CHECKING AND REPLACING WEAR PLATES

Wear bars are welded into the jaw and must be replaced after they have worn down to 1/4 their original thickness.
Using the MDP parts manual, ensure you have ordered the proper wear plate kits.
Installing Wear Bars
1. Preheat the area around the wear bar to 250° to 300° F.
2. Remove the worn wear bar.
3. Fit the new wear bar into the receptacle.
Note: Wear bars are pre-cut to length and must be formed to the jaw in the field.
4. Weld the wear bar into place.
