Since various assembly combinations are available in each crusher size and because of manufacturing variations,
the weights shown above are approximate and they can vary 5 to 10%.
CAUTION
Check the weight of all loads before lifting. Make sure the lifting device and other components
that will support the weight of the load are in good condition and are rated for the weight of
the load.

NOTICE
Prior to starting the work, check that all PPE and Tools are in good and safe condition and
working properly. Check that all spare parts are correct for the equipment to be worked on.
2.4 Mobilization
▪ Ensure adequate lay-down area exists close to the crusher
▪ Ensure safe access to the equipment
▪ Obtain site specific work permits: Hot work, Confined space
WARNING
Oil products present environmental and fire risks and can cause injury if inhaled or brought
into contact with the skin. Follow your lubricant suppliers instructions and safety directions
when handling oil and greases.
▪ Remove the nuts from the flange on the pinionshaft housing that holds the assembly in the
bottom shell. Mark the position of the pinionshaft adjusting jackscrews and back off the top
jackscrews.
▪ Use the two square head withdrawal bolts provided in the flange of the pinionshaft housing
to remove the assembly from the fit in the bottom shell opening.
▪ Install eyebolt in the threaded hole on top of the pinionshaft housing, attach sling and apply
slight lifting pressure to the assembly.
▪ Place a counterbalance over the end of the pinionshaft assembly and apply hand pressure
to balance the pinionshaft assembly while sliding it out of the crusher. Once the pinionshaft
assembly is about two thirds of the way out of the bottom shell a second eyebolt can be
installed to help remove the assembly.
▪ Record thickness of gaskets on bottom shell flange.
FIGURE 1
▪ Remove the coupling half from the pinionshaft.
▪ On the drive end, remove seal plate (3190-2) with oil seal (3170-2).
FIGURE 2
▪ Remove the pinion retaining ring (3650-0) and press off the pinion (3050-0) from the shaft.
The pinion is shrunk fit to the shaft with 0.004 to 0.006" (0.10 to 0.15 mm) interference. See
Figure 3 for typical setup of pinion removal.
FIGURE 3
NOTICE
Assemble the bearing cone and cup raceways with faces stamped “A” facing the same
direction. Likewise with faces stamped “C”. Cone faces stamped “B” should face each other.

Spacer
Locknut
FIGURE 4
▪ Assemble the double cup and cone spacer of the pinion end bearing onto the pinionshaft
(3505-0), checking to make sure face stampings are aligned correctly. Assemble the second
heated bearing cone onto the pinionshaft and clamp the bearing assembly with the locknut
tightly against the shaft shoulder while it cools.
NOTICE
Always use the original thickness of gaskets with the same pinion and gear. Any change from
the original will change the tooth contact pattern on the pinion and gear.
Sight
gauge Oil level
FIGURE 5
▪ Remove oil fill plug (3575-0) and fill the pinionshaft assembly to the proper oil level
approximately 3.1 quarts (2.9 liters). Lubricant recommendations are found in Section 3.7
▪ Install floating drive shaft assembly. Realign the drive shaft if backlash was readjusted.
FIGURE 6
▪ If pattern on the load side is near the toe, move the pinionshaft inwards, removing gasketing
between the bottom shell and pinionshaft housing, and recheck contact pattern.
▪ If pattern on the load side is near the heel, move the pinionshaft outwards, adding gasketing
between the bottom shell and pinionshaft housing, and recheck contact pattern.
▪ Check and make final adjustments to backlash after establishing the correct contact pattern.
▪ For checking the backlash, first move the eccentric toward the pinion to remove all
clearance between the eccentric and the bottom shell bushing by placing a block of wood in
the crushing chamber on the opposite side of the pinion. If the mainshaft is installed, raise
the mainshaft assembly with the MPS. Applying 50 psi pressure above the level caused by
the static load of the mainshaft assembly should be sufficient to push the combined
mainshaft and eccentric assemblies toward the pinion to remove the clearance.
▪ Use a dial indicator to measure the circumferential movement of the coupling / sheave and
then calculate the backlash using the following formula. The backlash must be in the range
noted in the table below.
Model Gear Type Pinion Pitch Pinion Pitch Plane of Rotation
Diameter Backlash Backlash
42(50)-65 Spiral 15.33 0.051 - 0.061 0.067 - 0.081
(388.6) (1.30 - 1.55) (1.70 - 2.06)
54-74 (75) Spiral 16.0 0.057 - 0.070 0.076 - 0.094
(406.4) (1.45 - 1.78) (1.93 - 2.39)
60-89 Spiral 17.8 0.060 - 0.075 0.083 - 0.104
(452.1) (1.52 - 1.91) (2.11 - 2.64)
▪ To adjust the backlash, the pinionshaft assembly is rotated using the jacking screws.
▪ Loosen the bolts which hold the pinionshaft assembly to the bottom shell. Loosen the hex
nuts locking the jacking screws. Adjust the jacking screws. Clockwise rotation will cause the
pinion gear to move downwards, towards the eccentric gear, reducing backlash.
Counterclockwise rotation will cause the pinion gear to move away from the eccentric gear,
increasing backlash. Lock the jacking screws with the hex nuts, tighten the pinionshaft
assembly bolts, and remeasure backlash.
