15 TIMING CASE AND DRIVE ASSEMBLY
To fit
1 Renew the "O" ring (A1). Lightly lubricate the
components with clean lubricating oil before they
are assembled onto the hub.
Check that the four cap screws (B4) which secure
the idler hub bracket (B2) to the timing case are
tightened to the correct torque 35 Nm (26 lbf ft)
3,5 kgf m.
Fit the hub (A9) with the "O" ring towards timing
case. Fit the three M10 cap screws (B3) and
tighten them to 60 Nm (44 lbf ft) 6 kgf m). Put the
needle roller bearing (A7) into position on the hub.
Caution: Do not rotate the engine crankshaft or the
compressor crankshaft if the idler gear (B5) is
removed. If either of the crankshafts are moved, the
compressor must be timed to the engine.
2 Lightly lubricate the bore of the gear (A11) with
clean lubricating oil and put the gear in position on
the bearing. Put the plate (A10) in position. Fit the
setscrews (A8) and tighten them to 22 Nm
(16 lbf ft) 2,2 kgf m.
3 Use the method shown on page 15A.08
illustration B to check the compressor idler gear
end-float and page 15A.08 illustration C for the
timing gear backlash. See the data and dimensions
at the end of this section for the compressor idler
gear end-float and backlash dimensions.
