1. Disconnect boost line (1).2. Remove bolts (2), and remove fuel ratio control (3).3. To install, position the fuel ratio control on the back of the governor and install bolts (2) that hold it.4. Connect boost line (1) to the fuel ratio control.Disassemble & Assemble Fuel Ratio Control
Start By:a. remove fuel ratio control 1. Put Tooling (A) in a vise so that the station (hole) being used is not over the vise jaw. Place the fuel ratio control over the pins in Tooling (A). Remove bolts (3), and remove cover (24) and gasket (23).
There is spring force behind cover (6). Hold cover (6) in position, and slowly remove the bolts that hold it to release the spring force.
2. Remove bolts (5). Remove cover (6) from housing (9).3. Remove spring (7), washer (8), and diaphragm (20) from retainer (4). Remove retainer (4) from housing (9).4. Remove nut (2) from extension (18), and remove the extension from retainer (4). Remove valve (15), spring (21), and O-ring seal (22) from the extension.5. Remove spring (19), retainer (17), and spring (16) from housing (9).6. Remove piston (11) and valve assembly (13) from housing (9).7. Use Tool (B), and remove snap ring (12) and washer (14) from valve assembly (13). Remove piston (11) from the valve assembly.8. Remove seal (10) from piston (11).9. If necessary, remove the stem portion from valve assembly (13).10. Clean and inspect all parts. Make a replacement of all parts that are worn or damaged. The following steps are for the assembly of the fuel ratio control.11. If removed during the disassembly, assemble the stem portion of valve assembly (13) to the valve using 9S-3265 Retaining Compound.12. Lubricate seal (10) lightly with the lubricant being sealed. Put seal (10) on piston (11), and put piston (11) on valve assembly (13).13. Put washer (14) in position on valve assembly (13) and use Tool (B) to install snap ring (12) on the valve assembly.14. Place housing (9) on Tooling (A), and put Tool (C) in the bore of the housing. Lubricate Tool (C) with clean engine oil.15. Push piston (11) in position with a smooth swift motion. Remove Tool (C) from housing (9). Place spring (16), retainer (27), and spring (16) in the housing.16. Put O-ring seal (22) on extension (18). Put spring (21) and valve (15) in position on the extension.17. Lubricate the bore of retainer (4), and O-ring seal (22) with clean engine oil. Install extension (18) in retainer (4). Install nut (2) on the extension.18. Put diaphragm (20), washer (8), and spring (7) in position on retainer (4). Install retainer (4) in housing (9).19. Hold retainer (4) in position, and install cover (6) to housing (9). Install bolts (5) that hold the cover.20. Make a replacement of gasket (23), and install the gasket and cover (24) with bolts (3). Tighten the bolts to a torque of 6-12 3 N m (4-9 2 lb ft).End By:a. install fuel ratio control
