i need to replace the mechanical seal for water pump, 91 lt 250. i was wondering what sealant is a good choice for the process, assuming u need to use one?
Id probably use rtv, or the sealer used in between the case halves (forgot the name) but im not sure someone should chime in soon.
RTV should work. Yamabond, Hondabond, Threebond 1207B and Permatex Ultra Grey would work too.
It is best to use one of the case-bond glues between the cases (These sealers smell like airplane glue when curing). Case-bond is oil resistant and semi drying. RTV/Silicone that smells like vinegar when it cures is not really oil resistant. Over time silicone swells up and looses it's adheasan.
Ultra grey and ultra blue is not a RTV type silicone it is more closely related to threebond 1211.
Thx too all for the guidance...
