PROBLEM

Show/hide table

The existing roller for the elevator can seize, crack, or fail on certain 615C and 623G Wheel Tractor-Scrapers. If the existing roller fails it can/will inhibit the operation of the scraper elevator.

The new 3103510/">310-3510 Roller Assembly contains an improved roller-idler. The idler is lighter, has a larger transition radius under the shoulder, and has more shoulder material. The hardware improves the retention of the roller assembly to the elevator frame.

Rework Procedure

Show/hide table

Refer to the Service Manual as necessary.

1) Lower the scraper bowl to the ground.

2) Remove a flight and break the elevator chains to gain access to the middle elevator idlers shown in Illustration 1 and Illustration 2. Anchor the chain and flight assembly to the elevator frame to prevent it from slipping off.

3) Replace the elevator idlers with the new 3103510/">310-3510 Roller Assembly using a 7X0451 Nut-Full and 3S7023 Washer-Hard on each idler assembly.

Check to make sure the roller assembly is shimmed and in line with the sprocket and idlers on the same side of the elevator.

Tighten the nut to a torque of 1230 +/- 70 Nm.

4) Assemble the elevator chains back together to complete the assembly.
