Remove Seals and Bearings
Because the new spindle and sprocket hub must be
clean and dry when assembled, the existing bearings
must be at least partially disassembled.
Refer to Figure 8
32. Use a bearing seal puller, or right-angle pry tools, to
remove two:
68
816-138C SEAL DBL LIP 2.5 ID X 3.881 OD
Note: Removing seals is likely to result in seal damage,
rendering them unsuitable for re-use. The bearing
cone and cup, however, are re-used. Exercise
care to prevent damage to the bearings.
33. Remove and save two:
69
822-117C BRG CONE 2.00ID TIM33889
These cones are re-used, unless being independently replaced due to wear or damage.

About Bearing Seals
Refer to Figure 9 and Figure 10
The new bearing seals are supplied in two sizes:
26
816-012C SEAL 3.375 X 2.0 X.438 CR20125
27
816-138C SEAL DBL LIP 2.5 ID X 3.881 OD
The smaller diameter (inside) seals are installed into the
axle-cup weldments from the inside of the gauge wheel
weldment. The larger diameter (outside) seals are
installed from the outside.
Note that there are two different axle-cup weldments on
each gauge wheel:
1
a long hub, where the seal seats deeply, and
2
a short (shallow) hub.
These are reversed left-to-right on each side.
Bearing seals have distinct faces:
3 5
inner - toward sealed area (bearing)
4 5
outer - away from sealed area (bearing), and
The inner face has the seams of the shells. The
outer face has any printing on the housing. If the seal
has a visible taper at the outside diameter, the smaller
diameter side is the inside.
The seals and keyless hub must be installed in a specific
order, depending on the tools available. Using the suggested tools, the order used in these instructions is:
a. bearing cups (if not left in place)
b. inside seal in deep hub .
c. keyless hub (not shown on this page)

IMPORTANT !
Seals are hollow metal structures and are somewhat
fragile. The are not intended to be in contact with the
bearings. When installing them, carefully align them
so they are concentric with the shaft hole. Apply
insertion force across the entire face, or at least
equally along the entire outside diameter (as close to
the shaft diameter as possible). See page 3 for tool
suggestions.

IMPORTANT !
To protect the seals during keyless hub tightening, and sure proper spacing for keyless hub
alignment, the spindle must be fully seated in the
bearings. Do not over-tighten.

Loosely secure the hub with bolt ,
washer and flanged lock nut . If the
22 61 21 60

cross bolt cannot be passed through the hub, it may
be necessary to remove one of the washers
installed at step 57.

14 Dual Gauge Wheel/Spindle Update
Align Sprocket and Keyless Hub
About Final Sprocket Position
Refer to Figure 22
The keyless hub assembly moves as it is tightened.
before beginning to tighten, identify which style of weldment is present on your drill, and review the final target
clearances.
There are two major weldment variants present on drills
which are candidates for this update:
• Shallow Hub with Raised Inside End
Drills built before March 2009 are likely to have a
(6mm) raised edge (shown as dotted line in the fig-
ure). The open end wrench supplied with the kit
15
r
may be used as a spacing gauge on this type drill.
• Shallow Hub with Flush Inside End
Drills built during and after March 2009 are likely to
have shallow weldment with an inside face that is
nearly flush with the gauge wheel assembly side
plates. An additional
3
⁄
in (5mm) spacing gauge (not
16
included) is needed in this case. The majority of such
drills will already have keyless hubs, but these instructions still apply for a single- to dual-wheel upgrade.
The desired final clearance dimensions are shown in the
table at right.
After the keyless hub is tightened, there is provision for
adjusting the spindle position with the 2in washers in the
kit (plus any washers removed from the drill).

About Final Sprocket-to-Hub Position
Refer to Figure 23
The sprocket must be fully on the outside split cylinder of
the keyless hub. These instructions recommend that the
toothed face of the sprocket be aligned with the edge of
the hub cylinder at the nut end.
A small amount of hub cylinder may be exposed, but
revealing too much may allow the nut or inside collet to
strike a bearing seal.
61. Adjust position of sprocket on hub until
sprocket face aligns with edge of outer collet .

and tighten the spindle-hub assembly to at least:
300 ft-lbs (407 N-m).
Do not exceed:
409 ft-lbs (555 N-m).
The suggested 300ft-lb/407N-m can be achieved by
applying a known force at a specific distance from
the spindle center. If applying dead weight, the pipe
must be at horizontal.

Dual Gauge Wheel Operation
Updating the spindle, or upgrading from single to dualwheel ground drive, has no effect on drill Operations or
Adjustments. In particular, the gauge wheel revolutions
per area for calibration is unchanged.
Gauge Wheel Maintenance
Updating the spindle has no effect on drill maintenance,
other than that four bearings are freshly re-packed.
If the tire size/type changed during the update, the recommended tire pressure and wheel bolt torque may now
be different than for the previous tires and wheels.
