1. Manually turn the screws until they begin to tighten
2. Tightening torque:
4.5 ft lbs. (20 Nm)
Alternatively, ensure:
1. Pre-tightening torque:
2.25 ft lbs. (10 Nm)
2. Tightening torque:

Insert the new piston guide seal rings as far as possible into the relative seat on the pump casing
(Fig. 11), following the procedure described:

tapered bush into the hole in the piston guide (Fig. 11/a), insert the new seal ring on the buffer as far
as it will go (determined by the height of the buffer) into its seat on the pump casing (Fig. 11/b),
remove the tapered bush (Fig. 11/c).
