Locations for the wood pads
Illustration 2 g06095080
(A) Middle pad 400 mm (15.75 inch)
(B) Front pad 200 mm (7.9 inch)
If not applicable, wood pads (A) and (B) must be placed under the front instruments and middle of the chassis to raise and brake the machine as shown in the illustrations above.
The machine articulation should be disabled/locked out by using the turning prevent bar.

(1) Cable straps
(2) Air compressor oil return line adapter
(3) Speed/Timing sensor
Remove cable straps (1) from the two locations shown in Illustration 4. Disconnect air compressor oil return line adapter (2) and speed/timing sensor (3) before removing the oil pan.

(6) Clutch disengagement tool
(7) Engine turning tool
Use clutch disengagement tool (6) to disengage the clutch before turning the engine over.
Use engine turning tool (7) to turn the engine over during the rework procedure to expose different sets of connecting rod caps.
Illustration 7 g06095295
(8) Serial number batch number
(9) Connecting rod cap alignment number
Illustration 7 shows pistons number 1 and 6 at the lowest points in the engine rotation. At this point the serial number batch number (8) and connecting rod cap alignment number can be recorded.
Illustration 8 g06095313
(10) Connecting rod bolts
Replace connecting rod bolts (10). Follow the procedure below for the replacement of the connecting rod bolts.Note: Do not remove the connecting rod cap at any point of this rework procedure. Removal of the rod cap could disturb the connecting rod to connecting rod cap joint.
Remove the bolt on the tab side of the connecting rod and replace it with a new connecting rod bolt.
Tighten the bolt to 130 7 N m (96 5 lb ft).
Remove and replace the other bolt in the connecting rod cap. Tighten the second bolt to 130 7 N m (96 5 lb ft).
Turn the first bolt an extra 60° 5°. Then turn the second bolt an extra 60° 5°.
Repeat this process for each additional set of connecting rods until all connecting rod bolts have been replaced.
