0 Tighten the arm capscrews to torque value shown
below using drive extension tool part no. 667699
(35D/50D) or 676218 (70D).
35, 50D - 380-430 N.m.
70D - 922-976 N.m.
IMPORTANT: Be careful not to damage the
arm bar. Premature bearing failure will occur.
Short adapters are commercially available; Drive exten-
sion tool dimensions are provided to make your own tool
from an allen wrench. Do not use mild steel hex stock.
- Lubricate the bearing portion of the arm bars
with a thin film of chassis grease.
C. Customer Fabricated Arm
Installation
WARNING: A certified welder must use proper
welding procedures when welding arms to the
arm bases.
Clamps without arms are supplied with two arm bases.
Special forks can be welded directly to them or they can
be used as a base to fabricate custom built arms.
CAUTION: Weld fabricated arms to the arm bases only.
Do not weld or bolt special built arms or forks directly to
the arm bars.
The arm base material is AISI C-1020 with the following
specifications:
TENSILE STRENGTH
YIELD STRENGTH
CARBON CONTENT
CAUTION: The surface flatness of the arm base must
remain within 0.25 mm in the bolt area. Arm bars must
slide free manually.
1 Fasten the arm bases to the arm bars. Tighten the
arm capscrews to the torque values shown below
using drive extension tool part no. 667699 (35D/50D)
or 676218 (70D).
35, 50D - 380-430 N.m.
70D - 922-976 N.m.
2 Lubricate the cylinder rod threads, nut threads
and spherical portion of the nut with STP.
3 Install the washer on the rod end with the beveled
side facing the lug.
