2.
Place the new gasket on the new UMP so that all holes align (see Figure 8).
Gaskets from competitive UMPs will not seal properly and performance will be
reduced.
3.
Align the UMP positioning dowel insert in the proper hole in the discharge head (see Figure 7) and push the
UMP into position using hand force only. The UMP should be snug against the discharge head prior to
installing the UMP retaining bolts.
Use hand force to push the UMP onto the discharge head. If the UMP does not seat
snug against the discharge head, remove the UMP and correct the problem.
4.
Install the UMP retaining bolts and lock washers (see Figure 8). Snug and then torque the bolts using a cross
pattern technique. Torque to 7 ft-lbs (11 N•m).
Do not use the bolts to pull the UMP into position. Use the cross pattern technique.
Do not over torque the bolts. Not following instructions may cause parts to fail.
