Center Frame Walker Assembly
1.
On Models 6231-30’, 33’-36’, units will be shipped
with the walking tandems not being installed on the
lift legs due to the center frame assembly being over
height.
2.
The walkers are universal and can be installed on
either side, there is not a left or right side weldment.
3.
for the correct orientation of the
walkers, the inside tire should be leading and the
outer tire trailing on both sides. This will keep the
tires away from the disc blades in field operation.
4.
To install walker, verify there is a hardened steel
bushing installed into the bottom pin hole on the lift
legs. There should be one on each side of the pin
hole.
5.
Remove the 3/8-16 x 1” flange head cap screws from
the side of the walker and take off the cap plates.
There will be a gasket between the cap and the
walker bushing. Remove the 3/4-10 x 5-1/2” hex bolt
so the chrome pin can be slid out of the walker.
6.
Place walker under the lift leg and carefully hold a
thrust washer on each side while lifting the walker up
into line with the pin hole on the axle leg.
NOTE
Note that walker is orientated correctly for the side
being installed
.
7.
Slide in chrome pin with aligning the cross hole to the
lift leg. If needed use a small dead blow hammer, do
not use a steel headed hammer on pin. Install the
3/4-10 x 5-1/2” hex bolt and tighten the nut to 150
ft-lbs.
8.
The walker should now pivot on the pin. Reinstall the
gaskets and endcaps with the 3/8-16 x 1” flange
head cap screws. Torque the 3/8 cap screws to 28
ft-lbs.
9.
Grease both sides of the walker until grease is visibly
purged out and cavity is full.
10. Install the hub/spindle assemblies into the walkers
with 1/2-13 x 5” bolts and nuts to secure them. Install
the spindle into the inner hole of the walker.
11. The rest of the machine may now be assembled.
