Introduction
This technical information bulletin replaces a technical information bulletin that was written on September 26, 2005. Ignore the Technical Information Bulletin, "Small Off-Highway Trucks Separation of the Spindle (Axle) from the Strut Puller Plate". The component code is 7200.
Problem
Use of the 6V-6178 Puller Plate is not recommended for the removal of the struts on some off-highway trucks. The current design of the spindle has one side with one bolt hole. The opposite side of the spindle has four bolt holes. The steering arm attaches to the side with four bolt holes. The tooling requires the use of all four bolt holes.
Solution
In order to use the 6V-6178 Puller Plate , three holes need to be taped in the spindle. Use the following procedure in order to tape the three holes into the spindle.
- Disconnect the steering arm from the spindle. attach one 6V-6178 Puller Plate to the spindle. Use four of the bolt in order to attach the puller plate.
- Use one bolt in order to attach the second 6V-6178 Puller Plate to the opposite side of the spindle. Position the bar assemblies onto the bottom of the 6V-6178 Puller Plate . Ensure that the bar assemblies are level. Then, tighten the bolts.
- Use a center punch in order to mark the location of the three 34.0 mm (1.34 inch) holes.
- By using a 22.50 mm (0.885 inch) drill bit, drill the three holes to a depth of 60.0 mm (2.36 inch) at each center mark.
- Use a 1 - 8 tap in order to cut the threads to a depth of 44.00 mm (1.732 inch).
Note: When you add the three holes to the spindle, the spindle cannot be used on the opposite side of the machine. The spindle from the left side of the machine should only be used on the left side of the machine because the bolted joint between the steering arm and the back side of the spindle requires a machined surface.
