E.
Remove tap or bolt and secure spacer mount with a
3/8” - 16 x 1” self-tapping bolt, taking care to keep the
remaining pilot hole centered in the mounting hole of the
spacer mount. Tighten bolt securely.
F.
Drill remaining pilot hole to 5/16” and insert a 3/8” - 16 x
1” self-tapping bolt and tighten
(Fig.2)
.
II.
Apply a thin layer of grease to a 3/8” washer and
place on outside of clevis, over the swing bolt.
III.
Secure the swing bolt and clevis with a 3/8” - 16
grade A heavy hex nut.
IV.
Tighten heavy hex nut enough to eliminate side
play
(Fig.3)
.
G.
Repeat steps 8A-8F on opposite side of chassis.
9.
Make sure the adjustment holes in each jack leg above
the foot pad pin are 1/2” diameter. If not, re-drill hole with
a step bit or standard 1/2” bit, then deburr holes with a
countersink bit.
A.
Insert a 3/8” I.D. x 1/2” O.D. flanged bushing into the
second from the bottom holes in each jack leg.
B.
Apply a thin layer of white grease to the shaft of a
3/8” - 16 x 4” swing bolt and the flanges of the bushings.
C.
For each jack leg, do as follows:
I.
Align the mounting holes of the electric jack clevis
with the bushings from the rear of the jack leg and insert
the swing bolt through both sides with the shoulder and
3/8” washer on the inside of the jack leg.
D.
Thread a 3/8“ - 16 nut (“Silver Bullet”) lifting handle
onto the outside of the swing bolt. Tighten nut lifting
handle against the 3/8” - 16 heavy hex nut
(Fig.3)
.
NOTE:
For chassis that are constructed with “I” or “H”
beam main rails (front-to-back) and are uninsulated, go
to step 10. For chassis that are constructed with “I” or “H”
beam main rails or tubular frames and/or insulated, go to
step 12.
10.
From the rear side of an electric jack leg, measure
30” and place a mark on the bottom of each main rail.
Measure the bottom flange of each main rail, then divide
that measurement by four to determine the center location
of the mounting hole.
A.
Centerpunch the intersection of the lines, then drill a
1/8” pilot hole.
B.
Re-drill out the pilot hole to 3/8” and deburr with a
countersink bit.
