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.
Walking Tandem Instructions
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.
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.
