Procedure:

1. Place the unit on a flat surface. Properly chock wheels and engage the service brake. Perform your
company’s Lockout/Tagout procedure. If your company does not have a Lockout/Tagout procedure,
follow OSHA 1910.147 and 1910.146 Confined Space as appropriate.
Inspection Procedure
2. Locate the Bob Tail® Huck® bolts on the rear pivot cross member (Figure 1 shows an example
grouping of bolts per bracket on one side of the cross member).
There are four inspection scenarios that each Bob Tail® Huck® bolt must go through.
IMPORTANT: If the bolt fails at minimum one inspection scenario, then it must be replaced,
regardless if it passes other inspection scenarios.
IMPORTANT: If any one existing Bob Tail® Huck® bolt fails the inspection, then ALL of the bolts
in that grouping on that bracket MUST be replaced, regardless if others in that grouping pass the
inspection.

3. Inspect each Bob Tail® Huck® bolt to determine if it is fully swaged (see Figure 2 and Figure 3). If the
Bob Tail® Huck® bolt is not fully swaged, proceed to the Replacement Procedure.
• A fully swaged Huck® bolt has bumps creased in the collar flange (Figure 2, bottom image, and
Figure 3 shows a side view). All bumps on the Huck bolt must be creased.

4. Inspect each M16 Bob Tail® Huck® bolt to determine the thread amount measures between 0.429
inches and 0.976 inches (Figure 4). If the thread amount is outside these measurements, proceed
to the Replacement Procedure. This inspection scenario applies only to M16 Bob Tail® Huck® bolts.
If the bolts are not M16 Bob Tail® Huck® bolts, contact your McNeilus service dealer network for
assistance.

5. Inspect each Bob Tail® Huck® bolt to ensure the thread is not stripped. If the thread is stripped,
proceed to the Replacement Procedure.
6. Inspect each Bob Tail® Huck® bolt to ensure it cannot be turned by hand. If the bolt can be turned by
hand, it is too loose. Proceed to the Replacement Procedure.
7. If any one existing Bob Tail® Huck® bolt fails the inspection, then ALL of the bolts in that grouping on
that bracket MUST be replaced regardless if others in that grouping pass the inspection. After the
first non-conforming bolt is identified, then the remaining bolts in that grouping do not need to be
inspected as all will be replaced.
8. Repeat Inspection Procedure steps 2 through 6 for Bob Tail® Huck® bolts in another grouping on
another bracket.
9. Purchase the number of replacement bolts and nuts needed.
Replacement Procedure
Removal of bolts
1. Secure plate with a clamp to the longitudinal.
2. Remove the Bob Tail® Huck® bolts and collars.
• Use a grinder to cut through the collar and bolt at the base of the Huck® bolt (preferred method)
or use a torch to make the cut if a grinder is not available. See Figure 5 for location of the base of
the bolt.
3. Apply touch-up paint as required and allow to dry.

Installation of new fasteners
4. Apply Loctite® 242 to the new bolt (according to package instructions).
5. Insert the new flange head cap bolt from the back of the cross member to the front (Figure 6
provides an example of fastener orientation).
6. Install the new flange nut on the bolt.
7. Torque the fasteners to 275 ft.-lbs. using a torque tool with a tolerance range of +/- 10%.
8. Mark the new fastener with torque seal or paint pen to denote the correct torque has been applied.
9. Repeat Replacement Procedure steps 2 through 8 for each of the existing Bob Tail® Huck® bolts at
the cross member.

The above image should be used for hardware orientation reference only; it is not accurately displaying
a flange nut.
