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 the new style crowd cylinder only when the old style crowd cylinder

Both manifold block-to-crowd cylinder oil lines are maintained the same way except as noted.
