GAUGE AS-OIL LEVEL (DIPSTICK) 2844930 - Caterpillar

Remove the rubber caps (A). Then, use a metric ruler to measure the gaps between the top of the flat wear pad (B) and the inside surface of the outer stick.
Check for clearance on the lower wear pad. If the gap between the lower wear pad and the bottom surface of the outer stick is less than 0.5 mm (0.02 inch) proceed to Step 6, or more than 1 mm (0.04 inch) proceed to Step 7.
If the gap is less than 0.5 mm (0.02 inch), perform the following steps:

(3) 8T-4910 Bolts (4) 222-5171 Setscrew
Loosen the two bolts (3) that secure the lower wear pad in place.Note: Do not loosen the two bolts that are under the setscrew.
Loosen the setscrew (4) by one to two turns.
Slide the stick out 25 mm (1 inch) to 75 mm (3 inch).Note: The lower wear pad should return against the set screw. This will create a gap between the lower wear pad and the outer extendable stick.Note: Ensure that the wear pad is pulled back against the set screw. Tighten the bolts. Ensure that you can access the bolts after the stick has been extended by a few inches.
Return the machine to the previous setup. Refer to Step 2.
Measure the gap and make any needed adjustments.
If the gap is correct, apply 154-9731 Thread Lock Compound to both bolts (1) .
Torque the bolts (3) to 100 20 N m (74 15 lb ft).
Proceed to Step 11.
If the gap is more than 1 mm (0.4 inch), perform the following steps:
Loosen the two bolts (3) that secure the lower wear pad in place.Note: Do not loosen the two bolts that are under the setscrew.
Turn the set screw (4) clockwise in order to decrease the gap.
Measure the gap and make any needed adjustments.
If the gap is correct, apply 154-9731 Thread Lock Compound to both bolts (1) .
Torque the bolts (3) to 100 20 N m (74 15 lb ft).
Proceed to Step 8.
Check extension of the stick after adjusting the lower wear pad.
Set the stick horizontally to the ground.
Extend the stick and retract the stick in order to check for any vibrations.
If no vibration is evident, continue to the adjustment of the side wear pads. Refer to Step 1.
If vibration is evident, adjust the lower wear pad to the maximum gap of 1 mm (0.04 inch). If the vibration continues, contact the DSN.Note: A small amount of vertical movement of the outer slider is acceptable with a gap of 1 mm (0.04 inch).
Proceed to Step 1.Adjustment of the Side Wear Pads
