Remove exhaust diverter (10) with cylinder (3) attached, from the machine. The weight of exhaust diverter (10) and cylinder (3) is approximately 65 kg (145 lb). The following steps are for the installation of the exhaust diverter. 7. Remove and clean any adhesive that remained on cross beam (11) during the removal process. 8T-9013 High Temperature Adhesive/Sealant is used between the cross beam and the exhaust diverter. Prior to applying 8T-9013 High Temperature Adhesive/Sealant, the exhaust diverter must be installed using Steps 9 through 14 to check for the proper stroke. Refer to the topic "Adjusting For Proper Stroke" in this module. After the correct stroke has been obtained, remove the exhaust diverter and reinstall the exhaust diverter starting with Step 8 of this procedure. 8. Apply 8T-9013 High Temperature Adhesive/Sealant to the surface of cross beam (11) as shown. 9. Remove and clean any adhesive that remained on exhaust diverter (10) during the removal process.
