Zero-Max Torq-Tender Operating instructions

  • Hello! I've reviewed the Torq-Tender installation guide and understand it covers various mounting configurations such as shaft-to-shaft, through-shaft, and end-of-shaft setups. The guide provides specific instructions for shaft alignment, securing the coupling, and adding external components like sprockets and pulleys. I'm ready to help answer any questions you might have about installing your Torq-Tender.
  • What should be checked before installing Torq-Tender in Through-Shaft Mount configuration?
    What is the required shaft alignment for Shaft-to-Shaft Coupling configuration?
    What is the minimum shaft protrusion into the bore for shaft to shaft configurations?
    What is the driver/driven limitation for CP model?
1. Align the shafts and shim components as needed to bring into
alignment. Shafts should be aligned to within 0.010″ parallel,
1.0° angular, and axial shaft separation to match the shaft
engagements shown in the catalog.
2. Examine shaft and clean as necessary. Shaft surface should be
clean and free of corrosion.
3. Mark the aligned location and remove either the driver or driven
component to allow the Torq-Tender to be slid onto the shaft, with
a shaft key in place.
4. Reinstall the driver or driven component that was removed to the
aligned location, installing the shaft into the bore of the Torq-
Tender, with a shaft key in place.
5. Shafts should protrude into the bore of the Torq-Tender at a
minimum 1/2 the bore depth listed in the catalog and maximum to
that bore depth.
6. Conrm alignment of the connected shafts by rotating and moving
the coupling axially. If the Torq-Tender does not move freely, the
shaft alignment needs to be redone (repeat step 1).
7. Tighten setscrews to secure the Torq-Tender to the shafts.
Note: Either end can be the driver or driven end for C and CD
models. For CP model, the housing (F bore) end must be
connected to the driver so pin will rotate in fault condition.
1. Check that the free length of the shaft is greater than the length
of the Torq-Tender.
2. Examine shaft and clean as necessary. Shaft surface should be
clean and free of corrosion.
3. Install the Torq-Tender onto the shaft with a shaft key in place.
4. Shaft should protrude through the full length of the Torq-Tender.
5. Tighten setscrew(s) to secure the Torq-Tender to the shaft.
6. Remove retaining ring at the bushed end of the Torq-Tender. Install
customer-supplied sprocket, sheave, or other component overtop
the external keyway, with a key in place.
7. Secure sprocket, sheave, etc. with setscrew(s) and also reinstall
the retaining ring at the end of the Torq-Tender for additional
means of retention.
Note: Either end can be the driver or driven end for B and BD
models. For BP model, pulley must be driver so pin will
rotate in fault condition.

4. Install the Torq-Tender assembly onto the shaft with a shaft key
in place.
5. Shaft should protrude into the bore of the Torq-Tender at a
minimum 1/2 the bore length listed in the catalog and maximum
to the bottom of the blind-end bore.
6. Tighten setscrew(s) to secure the Torq-Tender to the shaft.
Note: Either end can be the driver or driven end for S and SD
models. For SP model, pulley must be driver so pin will
rotate in fault condition.

5. Shaft should protrude into the bore of the Torq-Tender at a
minimum past the location of the setscrew(s) and maximum to
the bottom of the blind-end bore.
6. Tighten setscrew(s) to secure the Torq-Tender to the shaft.
Note: Either end can be the driver or driven end for J and JD
models. For JP model, pulley must be driver so pin will
rotate in fault condition.
