34 Precision Loads On-Board Weighing Installation & Service Manual
Do not pound on the load pin with a hammer or sledge. Tapping the load pin is acceptable but always
buffer the impact with a wooden block. If the load pin does not go into the pivot or cheek plates by hand,
or with moderate tapping, the capturing holes need to be aligned better, or opened up with a grinder.
5. Fit the collars to the load pins so they are tight to the pivot cheek plate. Install the bolt supplied through the
collar and load pin so the bolt is in a precisely vertical position.
6. Tack weld the collar in place. Remove the bolt and the load pin from the pivot area.
Weld around the periphery of collar with
1/4 weld allowing 3/4 inch free of weld top
and bottom for bolt head and nut.
Insure pin is mounted with the
steel stamped “UP” facing up.

7. Tack-welded collars may now be final-welded in place. Some installers prefer to re-insert the old pivot
pins in place during welding to maintain pivot positions and prevent movement or warpage during
welding. See drawing.
Weld around the periphery of collar with 3/16
weld allowing 3/4 inch free of weld top and
bottom for bolt head and nut.
Insure pin is mounted with the
steel stamped “UP” facing up.

Rice Lake Weighing Systems cautions against welding collars with load pins in place, as this can cause
damage to the load pin.

8. Allow collars to cool after welding. Re-insert load pins and bolt in place.
All load pins have an UP ^ mark on the end of the pin opposite the cable end. Make sure that the load pin is
installed so that the UP ^ mark faces upwards when load pin is bolted through collar.
9. Bolts used in collars to lock load pin position must always have the bolt head on top and the locknut below
the collar.
10. Relax body off jacks or overhead lift. Test the installation by raising and lowering the body with the hoist
cylinder. Look for any excess friction or binding.
11. Apply paint or underbody coating to the complete pivot area ensuring all bare metal surfaces and welds are
covered.
