6.2.3 Rocker Bearing Lock Nuts
After the first 40 hours of operation the rocker bearing lock nuts must to inspected and
tightened. To do this, put blocks of wood under the rear frame and raise the swingarms to lift the
wheels slightly off the ground. Remove the wheels and tires to gain access to the bearing
retainer caps.
Fold back the tag locking the nut and try to tighten the nut further. If the nut won’t tighten then
fold the tag back down and the nut does not need any further inspecting. If the nut tightens,
tighten it until the next tab and notch line up and fold the tab down. The nut will need another
inspection in another 40 hours of operation. Continue this pattern of inspection until the nut is no
longer able to be tightened. If after 3 inspections the nut is still found to require tightening
contact TOOMEY Earthmovers for advice.

6.3 Maintenance Intervals
6.3.1 Greasing
Once the initial bedding period has passed the hitch will require a minimum application of grease
at the start of each shift. The grease should be applied until new grease can be seen coming from
the thrust washers. The amount of grease required to achieve this will vary depending on the
type of use the scraper sees. It is highly recommended that grease be applied at shorter intervals
with as little as 3 hourly intervals being shown to provide sufficient grease for maximum life.
The wheel hubs only require two pumps of grease every 50 hours into each grease nipple.
NOTE: Failing to check that the nut is sufficiently tight will result in the inner part of the
bearing moving on the shaft and causing wear and damage. Damage which occurs as a result
of not following these guidelines will not be covered under warranty.
