SEALING UPPER AND LOWER CRANKCASE SECTIONS
Note
Only Loctite 574 (orange) should be used as a sealant.
Loctite 574 will dry only in conjunction with metal
and exclusion of air. After applying a coat of sealant
the bolts should be installed and tightened no later
than 10 minutes, since the sealant on the metal will
start to dry.
Removing Old Sealant
The old sealant does not have to be removed for repairs
It is only necessary to remove grease from the surface,
so that after the cleaning solution has dried the new
coaf of sealant can be applied. The new Loctite will
dissolve the old sealant in the surface finish and dry
again after assembling.
We recommend a fine steel brush or Loctite remover
80646 for removing old sealant, if this is ever neces-
saw.
Applying Sealant
1. We recommend a short-pile velour roller for appli-
cation by hand. A tray will also be required for the
sealant and should have a rough edge to scrape
excess sealant from the roller.
