DisassemblyNBPD0033PRE-INSPECTIONNBPD0033S01Before disassembling final drive, perform the following inspection.
ITotal preload
a) Turn drive pinion in both directions several times to seat bear-
ing rollers correctly.
b) Check total preload with Tool.
Tool number: ST3127S000 (J25765-A)
Total preload:
1.2 - 2.0 N´m (12 - 20 kg-cm, 10 - 17 in-lb)

2. Put matchmarks on one side of side bearing cap with paint or
punch to ensure that it is replaced in proper position during
reassembly.
Bearing caps are line-bored during manufacture and should
be put back in their original places.
