SAFETY INSTRUCTIONS
1.1 Range of Application
Challenger Worm Gear Actuators are quarter-turn gearboxes intended to be used for the operation of valves (eg. Butterfly
Valves, Ball Valves, Damper etc.).
This gearbox is designed for not only manual operation but also motorised operation. If you need to use for other applications,
please contact [email protected].
Challenger are note responsible for any damage caused by incorrect use of the gearbox. The qualified personnel must be fully
aware of the instructions as described in this manual.
1.2 Maintenance
For safe operation of Worm Gearbox, please observe maintenance instructions (pg 12).
1.3 Warning
This manual contacts Warnings, marking activities or procedures which, if not carried out correctly, can affect the safety of
persons or material. Every caution should be taken to ensure all instructions contained herein are fully understood and
addressed during operation.
WORM GEAR ACTUATORS
SBWG SERIES
4 QAD#IM1065, REV A, 20.05.2015
FEATURES AND FUNCTIONS
Housing All external castings are Ductile Iron Class 65-45-12, Tensile Strength of 65,000PSI.
This provides high strength and excellent impact.
Housing Cover Indicators, "Close-Open-Close" are cast directly on the cover.
This permits operation in either direction with position indication.
Worm Gear
Standard material is Ductile Iron, Grade 80-55-06, suitable for most Industrial applications. Normally required for motorised applications involving modulating service and is also a
requirement to meet the AWWA standards. The internal is splined to accept the splined bushing.
Worm 4140 Heat Treated Steel, with ground and polished worm threads.
Precision cutting of the threads provides minimum backlash between the worm gear and worm.
Splined Bushings All units furnished with removable splined bushings to permit accurate position between the
gear drive and the valve shaft.
Thrust Washer The drive sleeve is furnished with hardened steel thrust washers above and below worm
gear. This minimises frictional losses between the gear and the ductile iron castings.
Indicator Plate Pointer provides positive position indication.
The pointer can easily be repositioned if required.
Tapered Roller Bearing The worm is supported on tapered roller bearings which support both the axial and radial
forces generated by the gearings. They have excellent load bearing capacity.
Gasket Each end of the worm assembly is equipped with special design material (non-asbestos),
which are completely water resistant.
External Adjustable Stops The stop bolts allow for position accuracy of +/- 5.
Output Torque Units are available with single, double and triple reduction spur gears. This series of Worm
Gears range from 310Nm - 54000Nm.
Self-locking The gearboxes are self-locking when at a stand-still under normal service conditions: strong
vibrations may cancel the self-locking effect. While in motion, safe braking is not guaranteed.

TRANSPORT, STORAGE & PACKAGING
3.1 Transport
Transport to installation site in sturdy packaging. If mounted together with actuator, attach slings or hooks for the purpose of lifting by hoist only to the gearbox and not to the actuator.
3.2 Storage
Challenger gears should be stored in a clean, dry area in their shipping containers. If stored for long periods of time, the actuator mounting bases should be lightly greased to prevent corrosion.
3.3 Packaging
The gears are transported within protective packaging which consists of environmentally friendly materials for easy separation and recycling.
FITTING THE HAND WHEEL
4.1 Hand wheel
For gearboxes designed for manual operation, the hand wheel is supplied separately. Fitting is done on site according to Figure 1.

FITTING THE HAND WHEEL (cont.)
4.2 Splined Bushing
All units furnished with removable splined bushings to permit accurate position between the gear drive and the valve shaft. Removal and reassembly of the Splined Bushing is as follows:
Assembly
1.) Turn gearbox face down
2.) Insert bush correctly into the worm gear - Insert bush into groove of worm gear - There are 2 grooves at bottom of worm gear - One groove is for open and the other is for close
3.) Fix spring
Remove
1.) Remove fixed spring using suitable tool (flat head screw driver)
2.) Remove splined bush

ENCLOSURE PROTECTION IP-67, 68
Definition: IP67: According to IEC 529, the conditions for meeting the requirements of enclosure protection IP67. Under the conditions for regular pressure and time, test regulation can meet to prevent ingress of water. (15cm-1m)
Contents:
- Challenger worm gearboxes in enclosure protection IP 67 fulfil the following requirements in compliance with
Challenger definitions.
- IP67: Complete enclosure protection for dust and no ingress of water during submersion. (Standard)
- IP68: Complete enclosure protection for dust and suitable to use continuously during submersion.
- Test regulation is to be agreed between manufacturer and user. (OPTION)
- If submersed in other media, additional measures for corrosion protection may be necessary.
(Please contact Challenger Valves and Actuators)
Note:
The enclosure protection IP 67 is available to the interior of the gearbox, but does not protect mounting flange. If
gearboxes are likely to be repeatedly submersed, a higher corrosion protection may be necessary (Please contact
Challenger Valves and Actuators).
- Use suitable sealing material between valve flange and gearbox. - If unsuitable sealing material is used, water can not be prevented from entering the coupling via the mounting flange part, this leads to corrosion within the interior of the gearbox. - To protect from this type of corrosion, we would suggest you select higher corrosion protection before mounting valve.

MAINTENANCE
8.1 General Maintenance
- Check the external appearance for foreign matter and clean if required. - If coating is damaged this may lead to corrosion or rust, re-coat if necessary. - The gearbox is required to operate at least 10 times per year - Check the following points:
- Every 6-12 months check worm gear actuators for cleanliness and general condition.
- Valve must operate 5 times per 6 months.
- Check for grease leakage every 12 months. (Fill up grease if required)
8.2 Sealing
- Life cycle of NBR seals is about 12 years from manufacturing date. (The life cycle is based on average 40°C)
8.3 Grease
- Change grease as per below:
- In case of operating rarely: 10 to 12 years
- In case of operating normally: 6 to 8 years
- In case of operating frequently: 4 to 6 years
- Contact Challenger Valves and Actuators for grease specification.
- Do not mix lubricant with any other fluids.
- When removing lubricant and cleaning inside gear actuators, observe the correct instruction of replacement & remove (see 8.4)
- Challenger is not responsible for any damage caused by incorrect removal and replacement.
8.4 Removal & Replacement
- Challenger worm gears have a long life cycle, but proper replacement should be required to maintain this long life cycle.
- Challenger is not responsible for any damage caused by incorrect removal, assembly or replacement.
