NOTE
Original equipment crowd cylinders on loader backhoes with Serial Numbers 235786 thru 235999
are different from cylinders supplied on loader backhoes with Serial Numbers 319995 thru 342573.
Old style cylinder assemblies are not available for replacement and must be replaced with new
style when entire assembly is replaced. All necessary fittings, tubes, and hardware items required
for installation are included with new style crowd cylinder only when old style crowd cylinder part
number is ordered. If your loader backhoe has new style crowd cylinder installed, go to Manifold
Block-to-Crowd Cylinder Oil Lines (Serial Numbers 319995 thru 342573 only) (page 2-1578).
Both manifold block-to-crowd cylinder oil lines are maintained in same way. Manifold block-to-rod
end crowd cylinder oil line is shown. Repeat procedures as needed for manifold block-to-head
end crowd cylinder oil line.
