Today's entry is one of the final work sessions for the engine controls on the RV-12. I haven't installed the air cleaners as I think they have to be off to synchronize the carburetors.
NOTE: Vibration induced wear may occur wherever relative movement exists between contacting parts. Due to the potential for slight variations in the routing of hoses, cables, etc. within the engine compartment it is impossible for Van's to anticipate every instance of potential wear. Therefore the builder must carefully inspect the completed engine installation for any existing points of contact, like those listed below, and upon discovery perform the preventative measures described. Furthermore, once the aircraft becomes operational periodic inspections may reveal additional areas requiring these procedures.
Step 1: Apply approximately a 1/2 x1/2 x1/4[13 x13 x6mm] blob of high temp RTV sealant to the contact area between FF-1208B Output Radiator Hose and WD-1220 Engine Mount Ring.
Step 2: Apply approximately a 1/2 x1/2 x1/4[13 x13 x6mm] blob of high temp RTV sealant to the contact area between ROTAX PN: 922362 #2 Cylinder Water Tube (280mm) where it contacts the WD-1220 Engine Mount Ring.
Step 3: Inspect remaining engine installation for locations where contact exists.
Step 4: Apply high temp RTV sealant to any additional areas of contact.
