25 HD325, 405-6 Order of work Work procedure 1. Adjusting the body mount shim Adjust the body mount shim according to the following procedure. (1) Bottom mounts (Rubber mounts of body bottom plate) A. Insert a spacer 40 mm thick in the body end. B. Measure distance δ between the cen- ter of the body mount and the frame (6 places on both sides). C. Insert shims (δ1 - 38), (δ2 - 38), and (δ3 - 38) thick in the points of δ1, δ2, and δ3 respectively. D. Install the bottom mounts and re- move the spacers. E. Lower the body and check that all of the 6 bottom mounts are in contact with the frame top. F. Finish adjustment of the bottom mounts. (2) Front mounts (Rubber mounts of body front plate) A.
After the above adjustment of the bottom mounts, measure distances A1 and A2 between the body front mount and frame rear support. B. Set the thicknesses (quantity) of shims (569-74-61580) to (A1 - 51) mm and (A2 - 51) mm respectively. C. Install the shims having the thick- nesses calculated in B above and then install rubber pad (569-74- 61520). D. Lower the body and check that the total thickness of the rubber pad is 51 mm. If the total thickness is not 51 mm, adjust it to 51 mm with the shims. (Deflection: 1 mm) E. Finish adjustment of the front mount. • After the body is installed, the discrepancy be- tween the protector and cab must be 25 mm or less.
If the discrepancy exceeds 25 mm, adjust it to below 25 mm with the shims of hinge pin (566-97-46170).
