5 Maintenance
5.4.2 Fitting Shaft Assemblies
Step 1
Replace the shaft abutment spacer (27).
- For vertically ported pumps this is placed in the right hand bearing bore when viewed on the front face of the gearcase.
- For horizontally ported pumps the shaft abutment spacer is placed in the top bearing bore.
Step 2
Identify drive and auxillary shaft positions according to gearcase cover (5) orientation.
Step 3
1. Using a soft faced mallet tap the shafts (24 and 25) into the
gearcase (1).
2. If the bearings have been replaced, a new abutment spacer will
probably be needed. It is vital to ensure the rotor alignments is
within the limits set in section 5.4.4.
5.4.3 Fitting seal retainers
Step 1
Clean the rear face of the seal retainers (14), fit in position and tighten.
Step 2
1. Check rotor alignment is correct by reffering to the rotor abutment alignment in section 5.4.4.
2. When rotor alignment is correct remove seal retainers and press new lip seals (16) into seal retainers. For temperatures
greater then 130oC (266oF) FPM lipseals are fitted.
3. Apply liquid sealant onto the front of the gearcase (1) and push the seal retainers into position. Make sure lip seals are not
damaged when sliding them onto the shafts.
Step 3
Replace and tighten the screws (15).
