    The Gamajet V is designed primarily for portable service; the unit may also be permanently installed in a vessel. If the Gamajet V is permanently mounted inside a tank, we strongly recommend that you inspect the unit every few hundred hours of operation (see section 3 for details about Preventative Maintenance).

  • Page 4: Mounting

    1.2.3 MOUNTING While the dual nozzle unit is hydraulically balanced, the Gamajet V should be mounted on a rigid pipe. In most applications, the Gamajet V will be mounted in the "upright" position (inlet connection pointing up); however, if required, the Gamajet will function equally well inverted or horizontally.

    (BEP). For example, if the pump is rated for 23 GPM at 250 PSI, then the nozzles for the Gamajet V must be configured for the same 23 GPM at 250 PSI. If not, then you will increase the probability of experiencing premature failure of Gamajet V parts as well as shaft seals on the pump the farther away from the BEP that you operate the pump.
  • Page 6 WARNING Any tank cleaning machine can develop a static electricity charge while in operation. If the tank being cleaned contains a combustible liquid or vapor having a considerable risk of ignition or explosion, it is imperative to that the Gamajet be properly grounded. ©...

    2.2.5 Remove the two Nameplate Screws #47 with a Slotted Screwdriver and pull the Nozzle Housing #44 (#56 for Directional) off the Tee Housing #35/#55. If tight Bearings prevent removal, pry carefully between the Nozzle Housing and Tee Housing. 2.2.6 Unscrew the four Gearbox Screws #22 with a 7/64" Hex Ball-point L-wrench and pull the Gearbox #1 off the Gearbox Nose #14.

    and check their fit in the Nozzle Housing Cup #40 (#60 for Directional Machine). While they should turn freely in their Cups, the Nozzle Housing Bearings should be replaced if the diameter of the outside wall is less than 0.990" to avoid shortening the life of the Seals or Bevel Gears. 2.3.1.5 Nozzle Housing Seals #39 (#61 for Directional) Examine the Nozzle Housing Seals #39/#61 for loss of spring tension (indicated by excessive dry deposits of dirty or abrasive cleaning solution...

    If the planetary gears are removed as a single unit, any debris can be loosened and removed using an aerosol degreaser and air to dry. Once dry, the Planetary Gears can be lightly hand packed with grease. Gamajet recommends using a Chevron FM NLGI 2 grease for food grade applications and a Fuch’s ST-80 grease for aggressive chemical environments.
  • Page 14 2.3.4.3 Idler Gear #16 Inspect the Idler Gears for any worn, damaged or sharp/pointed teeth, or worn bushing flanges (the thickness of the flange or the lip should not be less than 0.050"). Check the Idler Bushings #17 for looseness. If the diameter of the inside wall of the Bushing is greater than 0.215", replace the Bushing.

    3.2.3 Reassemble the machine. 3.2.4 Return the machine to service. 3.3 INSPECTION INTERVALS The Gamajet V should be inspected every 100-300 hours of operation, depending on the severity of use. An interval of 100 hours is recommended initially. 3.4 TIPS 3.4.1 All the Bearings, Bushings, Seals and O-rings are wear parts.
  • Page 19 3.4.2 If just one Bearing or Seal is worn or damaged, replace both it and its mate, not just the worn or damaged part. 3.4.3 Reminder to never retighten Gearbox Nose Stem & Gearbox Screws, P/N 8-542 & 8-543. ALWAYS use new screws. Also, always resplit or use new Lockwashers, P/N 8-552.

    4.1.2 TIGHT CLEARANCES In low-flow applications (below 10 gpm), a newly-overhauled Gamajet V may fail to operate when first returned to service. If the machine seems otherwise fine, try running it with at least one Nozzle Tip removed. The additional flow will invariably be enough to overcome the extra resistance of new Bearings and Seals.

    If the Shaft will turn freely in one direction, but not the reverse, check inside the Planetary Gearhead #4 for damaged or broken gears. 4.1.5 GEAR TRAIN DAMAGE If the Input Shaft turns freely (from section 4.1.4) continue turning it to see if the Tee Housing #35/#55 also rotates.

    new one if it is hard or deformed. Install the O-ring so that it protrudes slightly; it will be compressed when the Bevel Gear and Retaining Ring are reinstalled. 4.2.4 WORN HOUSING BEARINGS Look for excessive wear on the Nozzle and Tee Housing Bearings #32 and #38/#59.

  • Page 23: Poor Cleaning Performance

    Inspect the Bearings #32 and #38/#59 and replace any that are excessively worn (clearance between the Bearing and the new Bearing Cup is more than 0.015"). Bearing clearances greater than 0.015" can prevent the Seals from functioning properly. 4.3.4 WORN OR ERODED CASTINGS Inspect the Seal contact surfaces of the Stem #24 and the Tee Housing #35/#55.
  • Page 24 This will result in partial or erratic washing coverage. Refer to sections 4.1 and 4.2. 4.4.5 GAMAJET CONFIGURATION Determine if the deposit being cleaned requires greater jet impact or longer jet dwell time (slower rotation) for more thorough scrubbing. Confirm that the Gamajet nozzle size, turbine, and gearing are correct for the specific application.
