4. New plugs should be screwed in tightly. Stake plug
with a prick punch at both ends of screwdriver slot
and around edges. Peen edge of hole 0.031 to 0.062
inches with a 1.5 inch diameter steel ball.
NOTE: If new plugs are being installed coat threads with
JLG Threadlocker.
5. Steps 5 thru 8 apply to shaft end cover, bearing car-
riers, and port end cover
Any bushings removed from the shaft end cover,
port end cover, or bearing carrier should be assem-
bled in drive bores with groove to the top of unit (12
o’clock). Assemble bushings in driven bores with
the groove to the bottom of the unit (6 o’clock).
Model P315 pumps do not have grooved bushings,
so the bushing seams should be placed at the 12
and 6 o’clock positions.
6. Bushings should be pressed into the bores, one at a
time using the special installation tool and an arbor
press. Be sure the grooves (or seams) are posi-
tioned as stated in step 5. Bushings must be
pressed into the bores flush with the casting face.
Be sure to support the castings so they are square
and level.
7. Repeat steps 1 and 2, stone and rinse parts.
