Notes:
• It is not possible to match the timing of the early
the compressor to the engine. Also it is not possible
to match the timing of the latest compressor to the
engine if the early drive assembly is used.
• If the latest compressor is to be used with the
early drive assembly, ensure that the drive gear
(26 teeth) from the earlier compressor is fitted.
• Also ensure that the new M20 nut (part number
3331E003) is used. When this nut is to be used
discard the tab washer and apply a narrow ring of
POWERPART Retainer (oil tolerant) to the bore of
the drive gear in the position shown in (A3). Also
apply POWERPART Nutlock to the thread of the
compressor crankshaft. Fit the nut and tighten to
130 Nm (96 lbf ft) 13,3 kgf m. Clean off excess
retainer (oil tolerant).
To fit the latest compressor only
1 Set the piston of number 1 cylinder to TDC,
operation 17A-01A/B.
2 Ensure that the dowels (B1) are fitted correctly in
the flange of the drive housing and fit a new joint to
the flange.
3 Rotate the crankshaft of the compressor until the
mark (C1) on the rear face of the crankshaft aligns
with the 6B line (six cylinder engines) or the 4B line
(four cylinder engines) on the label on the rear face
of the compressor.
4 Lubricate lightly the bush in the compressor
casing with clean engine lubricating oil. Put the
compressor in position on the studs of the timing
case. Slide the compressor forward until the
compressor gear is against the rear idler gear of the
drive assembly. Slowly turn the crankshaft of the
compressor clockwise (from the rear) until the
compressor gear will mesh with the rear idler gear.
5 Carefully push the compressor forward until the
gears are fully in mesh. In this position the mark on
the rear of the crankshaft should align with the dark
area marked 6 (six cylinder engines) or 4 (four
cylinder engines) on the timing label (C).
6 If it does not, pull the compressor out of
engagement and move the crankshaft of the
compressor in the relevant direction to mesh with
the next gear tooth. Carefully push the compressor
into position again and check that the mark on the
rear of the crankshaft is in the correct position. Fit
the nuts and the setscrews which fasten the
compressor to the drive assembly and tighten them.
