13.
Remove piston base cooling jets (1) following this procedure:
CAUTION:
Wear goggles with side protectors for this operation.
a.
• Drill the piston base coolibg jets using a [7 mm (0.3in)] diame-
ter drill bit.
NOTE:
Do not take out the ball from the piston base cooling nozzle, oth-
erwise swarf may enter the lubrification circuit
• Remove the spring tappet (1) and the springs (2) without tak-
ing out the ball (3).
• Remove any swarf present with a brush with non abrasive
bristles and a compressed air nozzle.
b.
• Screw the tool [SST: Mot. 1485-01] (1) into the drilled piston
base cooling jets using a [6 mm (0.2 in)] Allen key, which
slides into the tool [SST: Mot. 1485-01].
c.
• Screw the tool [SST: Emb. 880] (1) on the tool [SST: Mot.
1485-01].
• Remove the piston base cooling jets.
• Fit a blanking plug whenever a piston base cooling jet is
removed.
Assembly
1.
Fully air-blow engine coolant and engine oil passages in the cylinder block, cylinder bore and crankcase
to remove any foreign matter.
CAUTION:
Use a goggles to protect your eye.
2.
Install the new piston base cooling jet following procedure:
a.
Remove the blanking plugs.
b.
Use pressurised air and clean cloths to clean the oil circuit, the cylinders and the joint faces to ensure
there is no swarf present.
