Maintenance
In order to prevent machine failures, routine maintenance should be carried out every 500 hours of
operation. This should include cleaning all internal parts and assessing the wear of seals, gears, bearing
and bushes.
Any fine solid particles left inside the machine will increase wear considerably.
Please note:
– The Orbitor requires no lubrication.
– The Orbitor approved by Bureau Veritas; a copy of certification can be provided upon request.
Attention
- Before maintenance can be carried out, it is important the machine is not contaminated with
chemicals that could be hazardous
.
- Always use the tools stated throughout this manual. These can be purchased from BETE.
- Always read the technical data thoroughly before carrying out any work on this machine.
- Never service the Orbitor head while it is hot.
- After any maintenance is carried out it is essential the machine is flushed and sterilized before
further use.
- Any parts found to be unserviceable should be replaced before further use.
- The machine should only be operated at temperatures below 95°C (200°F)
- During operation, always ensure any tank openings are completely sealed off and can withstand
the full force of the striking jet.
- If the tank being cleaned contains a combustible liquid or vapour with a risk of ignition or
explosion, the Orbitor should be properly grounded.
- The machine should be allowed to gradually reach its operating pressure. A sudden spike could
cause parts to wear prematurely or fail.
Please Note – Any cleaning fluids must be stored/disposed of in accordance with current
rules/directives.
Please Note - Always record any wear found and check the smooth operation of the
machine after maintenance.

Nozzle Head and Rear Plate – Disassembly (see Figures 1 and 2)
1) Place the Orbitor in the vice, holding onto rear plate flats (DM02142). Ensure machine is securely
held in place before proceeding to Step 2.
2) Use tool (DM00750) to unscrew nozzle head (DM02141), in an anti-clockwise direction.
Please Note - The assembly has 180° of lost motion.
3) The nozzle head (DM02141) should now be free to lift off
4) Lift machine off the nozzle head shaft (DM02143).
Please Note - Be careful not to lose any seals, spacers or bushes.
5) Check seal in nozzle head (DM00699) for wear or damage to the seal lip, if excessively worn or
damaged, then remove by cutting free.
6) There should be a ceramic seal insert (DM00698) left in the main body. This should be replaced
if the ceramic coating is chipped or worn.
7) The bush (DM02032) will still be inside the main body (DM02139) and should be carefully
assessed for signs of wear.
8) The nozzle head bevel gear (DM02147) should still be on the nozzle head shaft (DM02143) and
should also be assessed for any signs of wear to the gear teeth.
9) Inspect the stream straighteners for any foreign bodies and remove if necessary.
10) Check rear plate seal (DM00699) for wear or
damage to the seal lip.
11) Turn main body (DM02139) over and inspect
second ceramic seal insert for wear or damage.

12) Now both bushes (DM02032) in main head can be removed but only if they are required to be
replaced.
13) Lastly the nozzle head bevel gear (DM02147) can be lifted off the nozzle shaft.
14)For Hi-capacity version see Figure1, Page 11.
Body Shell and Inlet Casing – Disassembly
1) Hold machine by inlet casing at the bottom and
turn the body shell (DM02140) counter-clockwise by
hand, or alternatively with a strap wrench if tight.
Please Note – To find part number for an Inlet Casing
refer to parts list.
2) This should allow spring clip (DM00686) to
extrude from slot. Unhook clip using a screwdriver.
3) Lift shell (DM02140) up from Inlet.
Please Note - You should be left with the cartridge
and turbine sub assemblies in inlet.
4) Pull out cartridge and turbine assemblies and
inspect for wear.
5) Remove stator bush (DM00695) if necessary
Turbine Shaft Subassembly – Disassembly
Please Note – Turbine can be removed from shaft if
necessary by unscrewing Hollow Set Screw
(DM00702) (see Figure 4). For specific turbine (rotor)
part numbers refer to parts list as these vary
depending on machine

Gear Cartridge
Subassembly – Disassembly
1) Check cartridge bush (DM00696), shaft bushes (DM00697), and support washer (DM02226);
inspect for wear.
2) Unscrew hollow set screws (DM00702) in both planet shafts, this should allow you to remove
both shafts (DM00736).
3) Now remove the planet gears; both the Aligned (DM00721) and the ½ Displaced (DM00722);
check for wear.

1) Fit the two side plate tools (DM00748) to the faces of the body and place in vice.
2) Using spider tool (DM00748), loosen spider
(DM02145 – Figure 9) from main body.
Main Body and Body Shell - Disassembly
(continued)
3) Lift shell and spider from ball and separate
internal components to ensure all thrust bearing balls
(DM00703) are retained. (Figure 9).
4) Inspect all seals, bearings, and bushes for signs of wear and replace if necessary.
5) Check spider and bevel gear teeth for wear.
6) Check ceramic seal insert (DM00698 – Figure 2) on body shell.
Main Body and Body Shell - Re-assembly
