Reassembly Note:
Before Reassembly visually inspect parts. See that parts are clean and all sealing surfaces are free of corrosion
and nicks. Remove any metal chips from casting cavities and tapped holes. Also inspect for any damaged or
excessively worn parts which should be replaced.
a. Coat the engine crankshaft with a thin layer of gasket sealer, such as, Loctite Gasket Eliminator 504
b. Lubricate the groove in the pump shaft sleeve using a multipurpose grease and install “O”-ring in
groove. Slide this assembly on engine crankshaft.
c. Position pump head on engine and align holes. If original screws are in good condition, reuse, but
apply a thread locking adhesive, such as Loctite Threadlocker 242 or equal to threads. If original
screws were damaged, or corroded, replace with four new screws. When installing screws use a new
brass sealing washer under the head of each screw.
Note: Hale has available small tubes of Loctite Threadlocker 242 adhesive (0.5 cc). Hale
