Remove retainer (25) from housing (10).5. Remove tube (1) from the end of extension (19). Remove nut (2) from extension (19), and remove the extension from retainer (25). Remove valve (16), spring (22), and O-ring seal (23) from the extension.6. Remove spring (20), retainer (18), and spring (17) from housing (10).7. Remove piston (12) and valve assembly (14) from the housing.8. Use tool (B), and remove snap ring (13) and washer (15) from the valve assembly. Remove piston (12) from the valve assembly.9. Remove seal (11) from piston (12).10. If necessary, remove the stem portion from valve assembly (14).11. 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.12. If removed during disassembly, assemble the stem portion of valve assembly (14) to the valve using 9S3265 Retaining Compound.13. Lubricate seal (11) lightly with the lubricant being sealed. Put seal (11) on piston (12), and put piston (12) on valve assembly (14).14. Put washer (15) in position on the valve assembly and use tool (B) to install snap ring (13) on the valve assembly.15. Place housing (10) on tooling (A), and put tool (C) into the bore of the housing. Lubricate tool (C) with clean engine oil.16. Push piston (12) into position with a smooth swift motion. Remove tool (C) from the housing. Place spring (17), retainer (18), and spring (20) in housing (10).17. Put O-ring seal (23) on extension (23). Put spring (22) and valve (16) in position on the extension.18. Lubricate the bore of retainer (25), and O-ring seal (23) with clean engine oil. Install extension (19) in retainer (25). Install nut (2) on extension (19).19. Place tube (1) on the end of extension (19). Heat the tube to 149° C (300° F) with dry heat only until the tube shrinks.20. Put diaphram (21), washer (9), and spring (8) in position on retainer (25). Install retainer (25) in housing (10).21. Install stop (4) and nut (5) in cover (7).
