    Pump / Impeller Molybdenum Grease

    I'm reassembling my pump and the Service Manual states that the splines on the drive shaft must be greased with molybdenum disulfide grease. What I can find locally is a grease which is lithium based with molybdenum disulfide as one of the ingredients. It's called 'moly grease'. Before moving forward I wanted to check with the experts and make sure this is the right stuff - i.e. is any grease with molybdenum disulfide good enough? Thanks.

    I called around... The dealership was clueless but they are going to research it (not much confidence in that one). What I've found is there are different % of molybdenum disulfide such as 6% to 60%. It sounds like for drive shaft splines, the higher percentage is best as it holds up under the temperatures where as liquid grease will squeeze out. The Service Manual doesn't state the % required; anyone know what is needed? I found a 60% paste by Honda that looks promising (online source). Thanks!
