If manifold assembly has been removed from the crankcase assembly, place the assembly on a clean work surface.
Remove all of the valve plug assemblies from the manifold assembly using a 7/8” socket wrench or combination wrench.
Remove the valve (44) from the assembly, followed by the valve spring (45). With the aide of a pick remove the o-ring
(46) from the valve plug.
Clean and inspect all valve plugs (47) prior to reassembly. If there is a problem, contact your dealer. Once all valve plugs
(47) are clean and dry, install new valve plug o-ring (46) onto valve plug (47). Install the valve spring (45) onto the valve
plug (47), it should now be attached to the plug. Press the valve (44) onto the valve spring (45). Complete valve

Inspect the manifold (38) for debris or other fouling and clean if necessary. Inspect the valve seat surface in the manifold.
If there is a problem contact your dealer. Reinstall all the valve plug assemblies with a 7/8" socket wrench or combination
wrench and tighten.
NOTE
Valves may be serviced while the manifold assembly is attached to the crankcase assembly.
NOTE
Valve plugs (47) will be reused.
A light coating of silicon grease (PN. 21-1122) should be used on all new o-rings and seals.
Use of any other type of grease may result in o-ring or seal failure.
NOTE
A light coating of Anti-Seize Lubricant (PN. 85-0094) should be applied on all threaded parts, unless otherwise stated.
