C) To remove the cross shafts, remove socket head

bolts, clamp and spacers from both sides.

VSG 751-2101 compressors cross shafts.

VSSG 291-601 compressors cross shafts

Volume control cross shaft.

Capacity control cross shaft.

D) Drive the roll pins from pinion gear from one

side. Remove pinion gear. Slide the cross shaft

with the remaining pinion gear or spacers out of

the opposite side. Repeat the procedure for the

remaining cross shaft.

INSTALLATION OF CAPACITY OR VOLUME

CROSS SHAFTS

A) To reassemble either set of capacity or volume

ratio slide valve racks, install the cross shaft with

the pinion gear onto the back plate, place the

remaining pinion gear on the shaft and drive in

the roll pins. Install clamps, spacers and bolts

on both sides. Tighten the bolts to the recom-

mended torque values.

B) The slide valve sets must be synchronized on VSG

751-2101 and dual gate VSG 301-701 units. Both

slide valve racks for either the volume ratio or

capacity slide valves must engage the cross shaft

gears at the same time. Push the racks all the way

towards the suction end of the compressor until

they stop. Install washers and jam nuts on the

slide valve shafts. Repeat the procedure for the

remaining set of slide valve racks.

C) Install (2) guide rods to position the discharge

manifold. Install a new manifold gasket and

the discharge manifold. Install the dowel pins

and bolts, tighten manifold bolts to the recom-

mended torque value.

D) On VSG 751-2101 and VSSG 291-601 and VSG

301-701 compressors install the discharge.
