Fasten the caps to their respective con-rod shanks by means of M8x1x42 screws (fig. 10) lubricating both the
underhead and the threaded shank, proceeding in two stages:
• Couple the con-rod caps to their shanks, referring to the numbering (1, fig. 9).
Note the correct assembly direction of the caps.
1. Manually turn the screws until they begin to tighten
2. Tightening torque: 22 Ft. Lbs. (30 Nm)
Alternatively, ensure:
1. Pre-tightening torque: 7-11 Ft. Lbs. (10-15 Nm)
2. Tightening torque: 22 Ft. Lbs. (30 Nm)

• After having completed tightening operations, check that the con-rod head has a side clearance in
both directions.
• Assemble the new piston guide seal ring with the relative seats on the pump casing (fig. 11)
following the procedure described:
Using tool p/n F27904200 composed of a tapered bushing and a buffer, screw the tapered bushing into the
hole in the piston guide (fig. 11a), 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. 11b), remove the tapered bushing (fig. 11/c).
