See the Systems Operation Testing & Adjusting Manual for the adjustment of the fuel ratio control.Disassemble Fuel Ratio Control
Start By:a. remove fuel ratio control FLUID SPILLAGE CONTAINMENTCare must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "TOOLS AND SHOP PRODUCT GUIDE, NENG2500", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates. 1. Remove O-ring seal (1) from the fuel ratio control. 2. Put Tooling (A) in a vise as shown so that the station being used is not over the vise jaw. Place the fuel ratio control over the pins in Tooling (A). Remove cover (2) and the gasket from fuel ratio control.
There is spring force behind cover (3). Hold cover (3) in position, and slowly remove the bolts that hold it to release the spring force.
3. Remove cover (3) from housing (4). 4. Remove O-ring seals (5) and (6) from the governor housing. 5. Remove spring (9), washer (7), and diaphragm (10) from retainer (8). Remove retainer (8) from housing (11). 6. Remove nut (16) from extension (15), and remove the extension from retainer (8). Remove valve (12), spring (13) and O-ring seal (14) from the extension. 7. Remove spring (18), retainer (17) and spring (19) from the housing. 8. Remove piston assembly (20) from the housing. 9. Use Tooling (B), and remove snap ring (21) and the wave washers from valve assembly (22). Remove piston assembly (23) from the valve assembly.10. Remove seal (24) from piston (23). 11. If necessary, remove stem (26) from valve (25).12. Clean and inspect all parts. Make a replacement of all parts that are worn or damaged.Assemble Fuel Ratio Control
1. Assemble stem (2) to valve (1) using 9S-3265 Retaining Compound. 2. Put seal (4) on piston (3), and put piston (3) on valve assembly (5). 3. Put two wave washers in position on valve (5), and use Tooling (A) to install the snap ring on the valve assembly. 4. Place housing (7) on Tooling (B), and put Tooling (C) into the bore of the housing. Lubricate Tooling (C) with clean engine oil.5. Put a small amount of clean oil on the seal of the piston assembly, and push piston assembly (6) into position with a smooth swift motion. 6. Place spring (8) and retainer and spring (9) in position in housing (7). 7. Put O-ring seal (12) on extension (13). Put spring (11) and valve (10) in position on the extension.8.
