PANEL GP-CIRCUIT BREAKER 2485667 - Caterpillar

MEASURING LINER HEIGHT PROJECTION
1-Dial indicator. 2-1P2402 Block. Measure and check the following dimension when installing new parts. With all dimensions correct, proceed with the above listed Steps.a. Top plate thickness .5150 .0005 in. (13,08 0,12 mm).b. Top plate gasket thickness, .008 .001 in. (0,20 0,05 mm). (All surfaces must be clean and dry when installing gasket.)c. Cylinder liner flange thickness, .5255-.5265 in. (13,35-13,37 mm).Connecting Rods And Pistons
Use 7M3978 Piston Ring Expander to remove or install piston rings.Use 7M3977 Piston Ring Compressor to install piston into cylinder block.Torque-turn-tighten the connecting rod bolt nuts in the following Step sequence. Viscous Type Vibration Damper
The viscous type vibration damper can be tested to determine if it is functioning properly. When the engine speed is reduced gradually from high idle to 2/3 of high idle, the timing gear train noise may be more noticeable at some speed within this range if the damper is faulty.The following test will indicate the condition of the damper.1. Attach hooks (1) in the mounting bolt holes. Clamp round rod (4) to the damper machined side and tighten nuts (6) to prevent shifting in handling. Use care in handling to avoid changing the rod location in respect to the original mounting on the damper.2. Support damper (2) between angle irons (5) on blocks (8). Angle iron edges and rod should have smooth contact areas.3. Place washers (3) on the light side to balance level (7). Record the number of washers.4. Stand damper on edge for 8 to 24 hours so the internal solid cast iron core can settle to the low side. Mark 6 o'clock (bottom) and 12 o'clock (top) locations on the damper.5. Repeat Steps 2 and 3.
CHECKING VIBRATION DAMPER (Typical Illustration)
1-Hook. 2-Damper. 3-Washers. 4-Round rod. 5-Angle irons. 6-Flat washers and nuts. 7-Level. 8-Blocks.6. Stand damper on edge at 12 o'clock mark for 8 to 24 hours.7. Repeat Steps 2 and 3.8. If balance washers have to be shifted between 6 to 12 o'clock locations in Step 3, the damper is in good condition. If the washers are continuously required at the same location, either 6 o'clock or 12 o'clock, it indicates the damper needs replacing because the iron core is not free to move but has become "locked up".Flywheel & Flywheel Housing
Heat ring gear to install. Do not exceed 600° F. (315° C.). Install ring gear so chamfered portion of gear teeth face the starter pinion when flywheel is installed.Checking Flywheel Housing Face Runout
Make tool setup from parts of 8S2328 Dial Test Indicator Group.
CHECKING FLYWHEEL HOUSING FACE RUNOUT
A-Bottom. B-Right side. C-Top. D-Left side.1. Fasten a dial indicator to the crankshaft flange so the indicator anvil will touch the flywheel housing face.2. Pry the crankshaft to rear before taking readings at each point.3. With dial indicator set at .000 in. (0,0 mm) at point (A), rotate crankshaft and take readings at points (B), (C) and (D).4. The difference between the lowest and highest readings taken at all four points should not exceed
