Lift Installation Into Busses - Wabtec RICON KlearVue K Series Service Manual

DECEMBER 2018
4. LIFT INSTALLATION INTO BUSES
Refer to Figure 2-7. Clamping bars are used on most bus installations to help distribute floor loading and should be
cut only if needed to clear a subframe member. Use the flange of a subframe member to support the clamping bar.
MINIMUM UNSUPPORTED
CLAMPING BAR LENGTH
LIFT WEIGHT IS APPROXIMATELY 340-370 LBS. TAKE EXTREME CARE WHEN POSITIONING BECAUSE
STEPWELL BRACKETS MAY TIP. THIS PROCEDURE MUST NOT BE ATTEMPTED BY ONE PERSON.
a. Open doors fully and position lift so that it is centered in vehicle doorway. Close doors and move lift out-
ward until it clears doors by a minimum of ½". The baseplate must be parallel to side of bus. Open manual
pump release valve (CCW) and allow folded platform to fully settle against latch on baseplate. Verify that
interference is not present between lift and doors. Reposition lift, if necessary. Close pump release valve;
do not overtighten valve.
Before drilling holes, verify that underlying wires and tubing will not be damaged.
b. Refer to Figure 2-8. Mark and drill ten 25/64" baseplate mounting holes (1 thru 10) through vehicle floor.
c. Fasten lift:
7) Insert ten 4" x 3/8" carriage bolts through baseplate and vehicle floor.
8) Install five support tubes on bolts underneath vehicle floor (across baseplate), i.e., from 1 to 5, 2 to 6,
etc, and secure lift to vehicle floor with 3/8" washers, lock washers and hex-nuts.
9) Use care when tightening carriage screws to prevent baseplate warpage. If baseplate assembly warps,
vertical arms will not be parallel. Make corrections by shimming at appropriate locations. To help pre-
vent warping, tighten the eight carriage screws to 28 ft-lbs in following sequence:
NOTE: Vertical Arms must be parallel for proper operation. Adjust screws as required. Best results are ob-
tained when lift is mounted on plywood. Shims, although best avoided, may be used if required.
