Thicker 1U-9646 Pusher And 1U-9647 Pusher Make XT-3 Hose Assembly Easier{0684}

Usage:

All Models Using XT-3 Hoses

Reference: SEHS8587; Special Instruction; 8T-5120 & 8T-5130 Crimp Tool Usage On XT-3 Hose

Warranty: G

Features/Benefits

* Used to crimp permanent couplings onto XT-3 hose assemblies (new parts upgrade existing 8T-5119 and 8T-5122 Crimp Tool Groups)

* Used with 7S-1100 Hose Press Arrangement, 6V-4900 Hose Press Arrangement, and 4C-9900 Hose Press Group

* 1U-9646 Pusher replaces cancelled 8T-5119 Pusher (part of 8T-5120 Crimp Tool Group) and 1U-9647 Pusher replaces cancelled 8T-5122 Pusher (part of 8T-5130 Crimp Tool Group)

* Pushers are now thicker and provide 6.0 mm (.25 inch) more travel

* Additional travel, provided by pusher, helps prevent lock-up of press (also prevents shearing of mounting plate pins if bolster contacts sleeve)

* Former pushers can be reworked by inserting 1U-9648 Plate between original two parts of pusher (saves expense of purchasing new tooling)

Typical Pusher Assembly With additional Thickness

Typical Former Pusher Assembly (1) 2H-3764 Bolt or 4L-7124 Bolt. (2) 1U-9648 Plate.

To rework former 8T-5119 Pusher and 8T-5122 Pusher, add 1U-9648 Plate (2). Use three new 2H-3764 Bolts (1) when reworking 8T-5119 Pusher. Use three new 4L-7124 Bolts (1) when reworking 8T-5122 Pusher.
