Swingjoint / Fluid Path Assemblies
Collins Youldon hosereels ha
ve two basic type of swingjoint / fluid path assembly. ¾”, 1” and 1 ¼” swingjoints
are external to the hosereel, see appendix 4 for more detail. These swingjoints can be replaced or serviced
without removing the delivery hose from the reel.
1½
” and 2” fluid paths are formed from several cast items, see figure 12 and appendices 3 and 4. The inlet and
seals of these assemblies can be easily replaced without removing the delivery hose from the reel, however
replacement of the spindle and/or shaft will require removal of the drum from the frame.
Leaking product may be due to a worn inlet seal or component. The inlet seal may need occasional
replacement but if the hosereel frame is twisted this will lead to irregular wear of swingjoint components.
Before replacing worn parts ensure that the frame alignment is correct, see Installation section 2.1.1 and
contact our Sales Department for advice.
