Walking Tandem Instructions
Walking Beam Disassembly
1. Loosen lug nuts on tires and remove both inner and
outer tire and wheel assemblies from the walking
tandem.
2. Remove walking tandem from axle leg. Remove
1-1/2” nut and pull pin out to let the walking tandem
assembly come loose. A new pin is supplied with the
update, but do not swell the end of the threads to
where they will not go through the axle leg by
hammering on them. Use caution as the walker with
the hubs installed is heavy once the pin comes out.
3. Remove the grease zerks from the walking beam.
4. With the appropriate driver, remove the steel insert
bushing from the walking beam (See Figure 1-1.)
Penetrating oil can be sprayed down the zerk holes to
aid in removal.The steel bushing is split on the side
with the zig zag edge and can be carefully cut with an
oxy/acetylene torch on the other to remove the
bushing if necessary.

CAUTION
5. Clean out all rust and scale left in the inner bore with
a honing tool of some sort. We recommend a ball
style hone.
6. With the 5/16-24 tap provided, finish tapping the
grease zerk holes so the set screw will go clear
through to lock the bushing into place. They were
tapped almost all the way through when produced,
but not completely so the threads need to be
completed to the bottom of the hole. If the walking
tandem has 1/4-28 tapped hole for the zerk, a 17/64
drill bit has been supplied to drill out the hole and
retap it to 5/16-24 threads.
Use care in removing the bushing to not damage
the inner bore of the walker as the new bushing
needs to be installed by hand.

Installation
7. Install set screws to verify they go completely through
the hole and can contact the bushing.
8. Clean/blow out all contaminants and apply some
lubricant to the new bushing and it should be able to
be pushed in by hand. If it takes much more force
than this pull it out and see if there are any
obstructions.

CAUTION
9. Once bushing is installed, center it up on the walking
beam so that neither side hangs out too far to
interfere with the thrust washers.
10. Install set screws and tighten down to contact the
bushing and snug them up. Do not over tighten as
this will crush the bushing (See Figure 1-2.)
Due to the seal being on the outer edge, the
bushing cannot be forced very hard or damage
will occur to the seal.

Walking Beam Reassembly
11. Using new pivot pin, apply a light coat of grease to
the chamfer to help installing the pin through the first
seal.
12. Align walking beam with axle leg, check to be sure
the hubs are in the correct orientation front to rear.
13. Install thrust washers into walking beam and lift into
place to insert pivot pin.
NOTE
We recommend using a floor jack or overhead hoist for
this as the holes need to match up close to avoid seal
damage when starting the pin.
14. By putting the cross pin into the pivot pin it allows
more leverage to turn the pin and push to get it
started. Once started and through the first seal, a
dead blow type hammer may be lightly used to finish
installation. The walker may need to be supported
some as the threaded side of the pin starts to come
out to avoid thread damage.
15. Install the slotted nut on the pivot pin and tighten to
750 to 900 ft-lbs and install roll pin to prevent it from
backing off (See Figure 1-3.)
16. Reinstall tire/wheel assembly torqueing nuts to the
value stated in the operators manual.
