24A AUXILIARY EQUIPMENT
To fit
1 Set the piston of number 1 cylinder to TDC,
operation 17A-01A/B.
2 Fit a new "O" ring (A5) in its recess in the drive
housing. Lubricate the "O" ring with clean engine
lubricating oil.
3 Rotate the crankshaft of the compressor until the
mark (B1) or (C1) on the rear face of the crankshaft
aligns with the 6A line (six cylinder engines) or the
4A line (four cylinder engines) on the label on the
rear face of the compressor.
4 Push the shortest thread of the stud (A4) through
the hole at the top of the compressor flange and fit
the nut fully onto the thread. Engage the stud in the
hole (A1) in the timing case. Slide the compressor
onto the stud (A3) for the bottom of the flange.
5 Slide the compressor forward until the teeth of
the drive gear are against the teeth of the idler gear
(A2). Slowly rotate the crankshaft of the
compressor clockwise (from the rear) until the drive
gear and the idler gear are in mesh.
6 Carefully push the compressor forward until the
spigot on the compressor is fully fitted in the timing
case. In this position, the mark on the rear of the
crankshaft should align with the dark area on the
timing label marked 6 (six cylinder engines) or 4
(four cylinder engines).
7 If the alignment is not correct, 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 assembly into position. Check
that the mark on the rear of the crankshaft is in the
correct position. Fit the nuts to the stud (A4) which
passes through the timing case (A1) and to the stud
at the bottom of the flange. Tighten the two nuts to
75 Nm (55 lbf ft) 7,6 kgf m.
