Sealing Upper and Lower Crankcase Sections

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 within 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 coat 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 80646 adhesive remover for removing old sealant, if this is ever necessary.

Applying Sealant

1. We recommend a short pile velour roller for application by hand. A tray will also be required for the sealant and should have a raised section to squeeze excess sealant from the roller.





2. Roll on a very thin coat of sealant with a velour roller.
