SWIVEL MANIFOLD MAINTENANCE
SWIVEL MANIFOLD ASSEMBLY
The swivel manifold assembly is located between the top bracket, which is pinned to
the carrier, and the processor frame that rotates. Hydraulic oil for both the open and
close operations of the processor passes through this manifold. The swivel manifold
assembly consists of two main parts, the “Spindle Case” (BZ), which contains the oil
seals, and the “Spindle” (CA), which rotates with the processor frame (see Fig. 1 ).

LEAKAGE OF THE SEALS
External leakage or internal bypassing of hydraulic fluid will require the replacement of
the seals in the swivel assembly. For external leakage, please review the seal
replacement procedure in the
“REPLACEMENT OF THE SEALS IN THE SWIVEL”
section of this manual. If internal leakage is suspected, please proceed to the
“TESTING THE SWIVEL SEALS FOR INTERNAL LEAKAGE” in the next section.
