ROD AS-CONNECTING 3590724 - Caterpillar

Installation Of The Generator
For information or alignment of two bearing generators make reference to Form No. SEHS7073.Typical installation and alignment procedure for electric sets with single-bearing generators. Do not start the alignment procedure until the electric set is permanently installed. If the electric set is moved to a different location, check the alignment and make any corrections necessary. The alignment between the generator and the engine must be correct to get maximum performance and long life from the electric set.
REAR OF ENGINE
A. Pilot bore. B. Surface.1. Remove all dirt, burrs and paint from the contact surfaces of the generator supports and the base.
FRONT OF ENGINE
1. Indicator group. 2. Crankshaft pulley.Remove the protection material (compound) from the flywheel pilot bore (A) and from the surface (B) that makes contact with the coupling. All contact surfaces of the engine, coupling and generator must be completely clean.2. Remove the timing pointer cover from the flywheel housing. Install indicator group (1) as shown on the front of the engine with the tip of the indicator on the face of crankshaft pulley (2). Use a bar between the flywheel and flywheel housing to push the crankshaft toward the flywheel to remove all end play. Put the dial indicator in the "zero" position. Move the crankshaft to its most forward position, and make a record of the Total Indicator Reading (TIR). The TIR is the end play of the crankshaft.
FRONT OF GENERATOR
3. Plate assembly. 4. Shim pack.3. Put plate assembly (3) in position in the bore of the flywheel to check for clearance. There must be clearance between the outside diameter of the plate assembly (3) and the inside diameter of the bore in the flywheel.
Damage to the engine and/or generator can be the result if the electric set is run with a plate assembly that does not have this clearance.
4. Install a full shim pack (4) and plate assembly (3) on the generator with bolts (5). On D379, G379, D398, G398, D399 and G399 engines, tighten bolts (5) to a torque of 370 35 lb. ft. (505 45 N m). On all other engines, tighten bolts (5) to the standard torque.
INSTALL PLATE ASSEMBLY
5. Bolt.
ENGINE FLYWHEEL
6. Guide bolt.
PUT GENERATOR IN POSITION
INSTALL BOLTS
7. Bolt. 8. Bolt.5. Install guide bolt (6) in the flywheel. Put the generator in position on the engine, and install bolts (7) and (8). Tighten bolts (7) and (8) but do not bend the locks under bolts (8) at this time.6. Use a dial indicator (1) to check crankshaft end play (do not use force to hold the crankshaft in position). Remove the generator. Remove only enough shims to get the original amount of end play as shown in Step 2.
PUT BOLTS IN POSITION
9. Bolt. 10. Generator support.7. Install the generator and again check the crankshaft end play. After the correct amount of shims has been installed, bend the locks under bolts (8).8. Install but do not tighten all bolts (9) that fasten generator supports (10) to the base. To
