SECTION 2 MAINTENANCE
4.0 Routine Maintenance: Drive Assembly
Providing the Drive Assembly is selected and installed correctly, the Drive should perform for a
long period of time with little or no routine maintenance. We recommend however, that checks
are made at least every 6 months. The only wearing parts of the Drive are the Bearings and the
Plunger Adaptors.
4.01 Bearings
Inspection of the bearings should take place regularly. If operating in clean and dry conditions we
recommend 6 monthly inspections of moving parts. If operating in wet and/or dirty conditions,
we recommend more frequent inspections, starting with monthly inspections until the operator is
comfortable with longer service intervals.
To inspect bearings, follow these steps (refer to ILLUSTRATION & PARTS LIST, Page 2):
1. For Simplex pumps, ensure the Liquid End is facing downwards, so that no liquid runs into the
Drive Case.
2.
For all pump configurations unscrew the Pump Connection Ring by hand to loosen and remove
the Liquid End/s.
3. Remove the Gearmotor or Gearbox by removing the 4 long screws attaching it to the Drive
Case
4. Unscrew the Bearing End Plate by removing the 4 screws
5. Remove the Crank Shaft and Bearings and inspect. You may need to move the Plunger Adaptor/s
to enable you to do this.
WARNING
: Should the bearings become worn in any way they should be replaced
immediately with new parts available from Solar Injection Australia or SiA Distributors.
6. Place the Crank Shaft and Bearings (or replacement Bearings) into the Drive Case
7. Place the Bearing End Plate back on the Drive Case and secure with the 4 screws
8. Reattach the Liquid End/s and tighten the Pump Connection Ring/s. You may need to carefully
push down and hold the Plunger into the Liquid End to enable you to do this.
9. Position the Gearmotor or Gearbox back on the Drive Case and secure with the 4 screws.
All three Precision Roller Bearings are sealed type and do not require in-field lubrication. They
have been selected using design loads far in excess of the loads that should be generated by the
design limitations of the product. Providing no moisture or dirt penetrates and that the Drive is
used in accordance with its design parameters a long life can be expected.
We have both Ertalyte and stainless steel versions of our Plunger Adaptors. No grease is applied
on assembly and providing abrasive dirt does not come between the Cam Bearing and the Plunger
Adaptor, negligible wear should take place through millions of cycles. If replacing Plunger Adaptor/s,
ensure you replace like for like as Ertalyte and stainless steel versions are not interchangeable.
To inspect Plunger Adaptor/s follow the steps outlined above for inspecting Bearings. After step 5,
remove and inspect Plunger Adaptor/s and then replace and continue to follow steps 6—9.
