Check and Replace Outrigger Bushings
Check outrigger bushings every six months according to the following procedure:
1. Extend the outrigger (Figure 4-7). With the jack raised, draw a pencil line where
the outrigger arm lines up with the latch pin mounting plate.
2. Lower the outrigger jack to raise the trailer wheel. Mark a second line where the
outrigger arm lines up with the latch pin mounting plate.
3. Lower the trailer. Measure the distance between the two marks. If the distance
exceeds 1/16 in., replace the outrigger bushings.
