VALVE GP-RELIEF 3293030 - Caterpillar

1. Fasten a hoist to the lifting bracket on the radiator.2. Remove two plates (5).3. Remove three bolts (2) and bracket (3) from each side.4. Remove four bolts (4) and upper shield (1). 5. Remove four bolts (6) and radiator (7). Weight is 250 Kg (550 lb.). For installation of the radiator, reverse the procedures of Steps 1 through 5.Disassemble Radiator
Start By:a. remove radiator and guard*1. Remove the fan guard.
Typical Example2. Remove four shields (1).3. Remove plate assemblies (2).
Typical Example4. Install two 1/2 in (NC forged eyebolts (B) into radiator top tank (4). Fasten chains and a hoist to the forged eyebolts. The weight of the radiator top tank is 50 Kg (110 lb.).5. Remove the bolts that hold the radiator top tank to the channel assemblies.6. Remove the nuts and washers from the studs on the radiator top tank. The studs fit into slots in the channel assemblies.
Typical Example7. Carefully, lift the radiator top tank off the core assemblies.
Typical Example8. At the front of the radiator, remove the bolts that hold the core assemblies to plate assembly (5).9. At each side of the radiator, remove the bolts that hold the outer core assemblies to the bracket assemblies.10. At the front of the radiator, remove seven strap assemblies.11. Remove the core assemblies from the radiator bottom tank.12. Remove the seals from the radiator top tank and radiator bottom tank.13. Inspect and replace damaged parts.*The radiator can be disassembled and assembled without removing radiator and guard.Assemble Radiator
Typical Example
Seals (1) and (2) are different. The top seals have a longer tab spacing than the bottom seals. Be sure the tabs engage with the holes in the tanks.
1. Apply liquid soap to the sealing areas of seals (1), and install them in the radiator top tank. 2. Apply liquid soap to the sealing areas of seals (2), and install them in the radiator bottom tank. 3. Install core assemblies (3) into the seals in the radiator bottom tank. Install the core assemblies with the bevel edges together.4. Install the bolts and washers that hold the core assemblies to plate assembly (4), but do not tighten them.
Typical Example5. Install the bolts and washers that hold the outer core assemblies to the brackets, but do not tighten the bolts.6. Install the bolts and washers that hold the core assemblies to strap assemblies (6). Do not tighten the bolts.
Typical Example7. Carefully, lower radiator top tank into position on the core assemblies.8. Install the top tank to the core assemblies and the channel assemblies. Install the bolts, washers and nuts, but do not tighten them at this time.9. Adjust the air gap between the core assemblies at the front of the radiator to 5 to 8 mm (.197 to .315 in.).10. Tighten the bolts as the adjustment for each set of core assemblies are made.11. After the air gap for all the core assemblies has been established, tighten the remaining bolts.12. Complete the assembly of the radiator.End By:a. install radiator and guard
