New 1000 Series
To fit
1 Set the piston of number 1 cylinder to TDC , see
operation 17-1 or , see operation 17-2 .
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.
