5.2 Pump Cleaning
Pump bracket, housing, impeller and shaft are all rugged, stainless steel. The pump bearings are
lubricated with high temperature grease. Heat is not the main reason for their failure – rather it is dirt
(dross, flux).

To Clean Pump
1. Hold pump in a vise for disassembly.
2. Do not remove leveling screws.
3. Clean all parts (except pump bearings) thoroughly:
•
Use mineral spirits to remove dirt.
•
Use a wire brush for easy to get at areas.
•
Use a scraping tool for hard to reach areas.
4. Inspect parts before reassembling (especially pump bearings). Check bearings for free, smooth
action – no binding or rough action, if so, replace.
Assembly (see Disassembly Procedure)
5. Be certain when assembling the pump housing to pump bracket that the alignment guides are
lined up exactly. This will insure that the pump is level when installed back onto the machine. If
they are not lined up or if the leveling screws were removed, the result will be an un-level solder
wave and very poor soldering or desoldering processes.
6. Spin pump shaft to be certain that the pump is assembled correctly before placing back on
machine.
