10.4 Replacing wheel bolt The wheel bolts on the transmission are stud bolts. To replace the wheel bolts, proceed as follows:
• Pull out the battery's emergency disconnector. • Remove the platform. • Lift the machine using a jack and put it on blocks. • Remove the drive wheel. • Wheel bolts with damaged threads are removed using the stud bolt tool. • Broken wheel bolts: • Method 1: Drill a hole in the centre of the bolt and screw out the bolt using a screw extractor for M14 bolts. • Method 2: If the bolt will not come loose with a screw extractor, the bolt must be drilled out. - Drive a centre punch into the centre of the bolt. Be careful to centre the centre punch. - Drill a pilot hole through the bolt using a 5 mm bit. Drill out the bolt using an 11.5 mm bit. - Try to remove the remains of the bolt with pliers or the like. If that does not work, remove the remains by clearing the threads with a screw tap M14x1.5. • Apply LOCTITE 270 on the threads of the wheel bolts. Mount the new wheel bolt with a stud bolt tool. Tightening torque 90 Nm Assemble the drive wheel. Tighten the wheel nuts to xx Nm. • Remove the blocks and lower the truck. • Assemble the platform. • Connect the battery disconnector. 10- 6
