Complete Assembly Procedure

Lubricate cup O.D. with a small amount of food grade gearbox oil.

Using tool # T-3 and an arbor press, press cup down into tee housing until the flange is seated flat on the tee housing.

Repeat procedure for other cup.

Wipe a small amount of food grade gearbox oil on I.D. of bearing cups.

This reduces the initial friction between the seals and cups.

Invert tee housing and place over bearing and seal on inlet stem.

Install lower seal, spring facing down towards the ports in the inlet stem.

Next, place the lower 631 bearing over the inlet stem with the tab facing up.

Install the ring gear retaining ring (621); place one end into groove in tee housing, then work the ring into the groove and press into place with a small screwdriver.

Be sure the retaining ring is completely seated in the tee housing groove.

Place the 3 gearbox bolt o-rings (641-3) into the counterbores of the inlet stem.

Lubricate the o-rings and the 1” bore of the inlet stem with gearbox oil.

This will prevent twisting of o-rings during assembly

Install a new o-ring (662) on the upper rotor shaft bearing housing (660-U).

Place the 660-U into the top end of the gearbox (601).

Install a new o-ring (642-3) on the gearbox, using a small amount of oil for lubrication.

NOTE: Flow-thru machines do not have a seal protector (659-3), or a seal retainer 611-3A (which has 2-639 orings and 2-641-TG seals).

Invert the gearbox, and place the seal protector (659-3) into the center bore of the gearbox.

Install two (2) new rotor shaft seals (641-TG) and o-rings (639) on the seal retainer (611-3).

Lubricate the o-rings and the bore of the gearbox, then place the seal retainer into the gearbox until it is seated against the seal protector

Replace o-ring (639), and lubricate with oil.

Place lower rotor shaft bearing (660-L) into center bore of gearbox; and line up the flat on the flange with the large bore in the gearbox.

This is important to prevent interference with the geartrain.

Press down with your fingers until (639) o-ring is seated.

Place tool # T-5 with a 12 oz. Hammer or use an arbor press to seat the flange of the lower rotor shaft bearing is against the gearbox bore face.

IMPORTANT NOTE: In order to maintain proper alignment between the upper and lower rotor shaft bearings, the flange of the lower rotor shaft bearing (660-L) must be completely seated against the face of gearbox (601-3) bore.

Place the T-8 seal protector over the end of the rotor shaft assembly (622-A), and insert the rotor shaft thru the upper (660-U) and lower (660-L) rotor shaft bearings.

The rotor shaft should spin freely; if there is resistance, it is probably because the flange of the lower rotor shaft bearing is not completely seated against the gearbox.

Reseat the lower rotor shaft bearing (660-L) with the tool # T-5, and test the alignment once again.

Apply a small amount of anti-seize compound to the threads of the bolts.

Install the 3 gearbox bolts with lockwashers.

Hand tighten bolts, then torque to 30ft/lbs for Stainless Steel, 23 ft/ lbs for Bronze.

If you do not have a torque wrench, tighten the bolts until snug.

Do not overtighten.

Install the final shaft seal (643-TG) into the final shaft bearing retainer (613-S) with the spring facing upwards.

Using an arbor press, press the final shaft upper bearing (629) into the final shaft bearing retainer (613-S).

NOTE: the flow-thru type gearbox does not use the final shaft seal (643-TG).

Align the square drive of the final drive shaft (616) with the square of the final drive gear (624).

Press the drive gear onto the shaft using an arbor press.

Install a new o-ring (640-3) on the final shaft bearing retainer.

Place the rotor shaft spacer (655) on the rotor shaft (622-A).

Place tool # T-8 seal protector on the rotor shaft end.

This tool protects the rotor shaft seals from damage during installation of rotor shaft.

Push rotor shaft thru lower rotor shaft bearing until pinion gear engages with 623-A gearset.

Remove the T-8 seal protector from the rotor shaft.

Rotate the rotor shaft to be certain that all of the gears are properly engaged, and the rotor shaft bearings are aligned.

NOTE: Flow-thru machines do not have rotor shaft seals and therefore you do not need to use tool # T-8 seal protector when installing the rotor shaft assembly.

Fill the gearbox with oil.

The oil level should just cover the (623-A) gearset on the final shaft (616) as shown in photo # 8.

All Lubricated machines are supplied with the following type of oil:

OIL TYPE: Food Grade U.S.D.A Acceptable H-1 QTY: 14 oz. (414 ml.) S.A.E.-90

Note: Flow-thru machines do not have oil in the gearbox, they are lubricated by the cleaning solution.

For non-food industry applications, H-2 lubricants can be used such as Keystone Keygear 90, KLC-20/50 or KSL-365.

Lightweight gear oils SAE 50-90 are also suitable.

It should be noted that heavy weight (140) gear oils or greases will alter the performance of the machine regarding cycle times.

Use tool # T-6 to press the rotor shaft thrust bearing (626-A) into the center bore of the gearbox cover (602).

Use tool # T-5 to press the idler shaft lower bearing (628) and the final shaft lower bearing (630) into their respective bores (refer to exploded view).

Install a new o-ring (644) with lubricant.

Lubricate the bore of the gearbox and the gearbox cover o-ring with gearbox oil.

Align the gearbox cover with the shafts (# 615, 616, 622) and the dowel pin hole in the gearbox.

Press down until o-ring is seated.

Install split washers (647) and gearbox cover screws (646).

Torque screws to 100 in/lbs for Stainless Steel and 80 in/lbs for Bronze.

Do not overtighten.

Turn machine right side up.

Place rotor (610) on rotor shaft (622). Install lockwasher (647) and rotor nut (654).

Tighten the nut while holding pressure against the rotor with a medium sized screwdriver wedged between the inlet stem and the rotor or use needle nose pliers to hold a fin on the rotor.

Torque the rotor nut to 100 in/lbs for Stainless Steel and 80 in/lbs for Bronze.

Be certain the rotor nut is tight, and that the rotor shaft is not rotating while tightening the nut.

Rotate the rotor (610) with your finger or a small screwdriver.

The rotor should rotate freely and the tee housing should begin to move slowly.

Lubricate cup O.D. with a small amount of food grade gearbox oil.

Using tool # T-3 and an arbor press, press cup down into nozzle housing until the flange is seated flat on the nozzle housing.

Repeat procedure for other cup.

Clutch Drive:

Wipe a small amount of gearbox oil into the groove of the nozzle housing (605).

Install a new o-ring (637).

Place the nozzle housing bevel (618) on the nozzle housing.

Install the bevel gear retaining ring (619) with a small screwdriver, be sure the retaining ring is completely seated in the groove of the nozzle housing.

Pin Drive:

Place the bevel gear dowel pin (661) into the hole in the nozzle housing.

Install a new o-ring (637).

Line up the slot on the bevel gear with the pin, then install the bevel gear retaining (619) with a small screwdriver, be sure the retaining ring is completely seated in the groove of the nozzle housing.

Nozzles and Stream Straighteners:

Tap stream straightener into nozzle with plastic faced hammer.

Place a small amount of anti-seize compound or Teflon tape on the threads and the radius on the end of the nozzle.

Insert the nozzle (607) into nozzle housing (605) and tighten with open end wrench or adjustable wrench.

Install one of the nozzle housing seals (636-TG), the spring side facing outward towards the ports in the tee housing.

Wipe a small amount of gearbox oil on the I.D. of the bearing cups (634) in the nozzle housing (605).

This reduces the initial friction between the seals and cups.

Place the nozzle housing assembly (605) over the seal and bearing on the tee housing.

Install the outer seal (636-TG), with the spring facing inward toward the ports in the tee housing.

Install the nameplate screws (648) and the lockwashers (647).

Torque screws to 100 in/lbs for Stainless Steel and 80 in/lbs for Bronze.

Do not overtighten.

Check for end play (in and out) of nozzle housing on the axis of the tee housing nose.

There should be some free play.

. Check end play (up and down) of tee housing.

Rotate the rotor with your finger or a small screwdriver.

The rotor should rotate freely and the tee housing should begin to move slowly.

NOTE: If you get negative results on any of these final inspections then refer to the trouble shooting guide that begins on page 11.

Place the stator (609) into the inlet stem (603) by rotating slightly until the weld on the I.D. of the inlet stem is in between 2 of the fins of the stator.

The weld on the inlet stem keeps the stator from rotating.

The stator retaining ring (645- 3) can now be installed using a pair of needle nose pliers.
