1. Maintenance Guidelines for Stanley Assembly Tools
Stanley assembly tools are designed for tightening threaded fasteners. Application variables such as torque level, free
run time, joint type, operator practices and maintenance procedures can affect assembly tool durability. The following
guidelines recommend maintenance intervals for specific tool types and components. Use the table at the bottom to
adjust the intervals for actual torque level. Special assembly tools such as crowfoot and tubenut tools are used where
space is limited. To fit into these spaces, typical robust design standards cannot apply, and these tools require more
frequent maintenance than standard tools.
Recommendation: Perform a torque capability test and calibration (for tools with torque transducers) after all
maintenance procedures-especially those that require tool disassembly.
Interval Recommended Preventive Maintenance
Monthly Safety inspection: Inspect condition of all air hoses or power cables and connections, Inspect tool
suspension components and torque reaction devices. Replace worn or damaged components.
Replace worn or damaged safety labels. REFERENCE SECTION 5 Note: Failure to perform this
inspection could result in unsafe and hazardous conditions being present
First 5,000
cycles
High Torque Crowfoot tools (250 NM and up): Inspect tool using external transducer every 1000
cycles to ensure calibration is accurate. Recalibrate if required.
25,000 cycles
Or Weekly
Tubenut tools: Lubricate gear head 2-3 pumps (Ref. 2a) Note: Failure to perform this
maintenance will result in damage to socket journals and mating housing surfaces causing
undue expense and down time.
Inspect housing, baseplate, socket, & socket bushings and replace any visibly worn components.

1. Maintenance Guidelines for Stanley Assembly Tools

Stanley assembly tools are designed for tightening threaded fasteners. Application variables such as torque level, free run time, joint type, operator practices and maintenance procedures can affect assembly tool durability. The following guidelines recommend maintenance intervals for specific tool types and components. Use the table at the bottom to adjust the intervals for actual torque level. Special assembly tools such as crowfoot and tubenut tools are used where space is limited. To fit into these spaces, typical robust design standards cannot apply, and these tools require more frequent maintenance than standard tools.

  • Recommendation: Perform a torque capability test and calibration (for tools with torque transducers) after all maintenance procedures-especially those that require tool disassembly.

Interval Recommended Preventive Maintenance

Monthly Safety inspection:^ Inspect condition of all air hoses or power cables and connections, Inspect tool suspension components and torque reaction devices. Replace worn or damaged components. Replace worn or damaged safety labels. REFERENCE SECTION 5 Note: Failure to perform this inspection could result in unsafe and hazardous conditions being present

First 5, cycles

High Torque Crowfoot tools (250 NM and up): Inspect tool using external transducer every 1000 cycles to ensure calibration is accurate. Recalibrate if required.

25,000 cycles Or Weekly

Tubenut tools: Lubricate gear head 2-3 pumps (Ref. 2a) Note: Failure to perform this maintenance will result in damage to socket journals and mating housing surfaces causing undue expense and down time. Inspect housing, baseplate, socket, & socket bushings and replace any visibly worn components.

Inspect housing, baseplate, socket, & socket bushings and replace any visibly worn components.

SECTION 2 - Lubricant Descriptions:

Ref. 1: Pneumatic tool motor lubricant: Air tool oil (emulsifying grade) Ref.2a : Gear Lubricant – Dow Corning MOLYCOTE® G-4700 EXTREME PRESSURE SYNTHETIC GREASE Ref. 2b: Gear Lubricant - #5 Planetary Gear case – output stage – 90 weight gear oil - fill to outflow port. Ref 2c: “ O” Ring Lubricant – “ O” Ring Lube

SECTION 3 - Life Expectancy Factor

Life Expectancy Factor (LEF): For many

components, operation above the rated torque can reduce the cycle to failure life. Operation below the rated torque can increase the cycle to failure life. Multiply MTBF rating by these factor for operation at other than rated torque

120% of rated torque 110% of rated torque 90% of rated torque 80% of rated torque 70% of rated torque

0.5 X 0.7 X 1.3 X 2.0 X 2.5 X

SECTION 4 - MTBF (mean time between failures) Guidelines

(MTBF) Guidelines for Estimating Spare Parts Use*

  • These are general guidelines - Individual tool models may have different MTBF (Mean Time Between Failures) ratings depending upon tool construction and the conditions described in SECTION 1

SECTION 5 – COMPONENT PART INSPECTION

Mechanical Load Transmitting Components – Gears, Spindles, Shafts, Couplings, Clutches, Springs,

Sockets

Replace if there is visible surface deformation (Brinnelling) – Surface scoring – Nicks – Cracks -

Pitting

Seals – O rings

Replace if there are -flat surfaces on the seal cross section – Notches – Cuts – Cracks - Pitting

Valves –

Replace if there is - visible surface deformation (Brinnelling) – Surface scoring

Ball Bearings –

It is good mechanical repair practice to replace ball bearings whenever a tool is serviced. Always

replace a ball bearing that has a rough / gritty feel when turned by hand.

Needle Bearings –

It is good mechanical repair practice to replace needle bearings whenever a tool is serviced. Always

replace a needle bearing that has produced surface scoring or heat discoloration on the mating

journal.

DC Tool Cables –

Replace cables that result in intermittent tool operation – when the outer jacket worn or cut exposing

metallic wire shield.

Air Hoses –

Check for leaks - Tighten fittings – replace if still leaking air.

Suspension Cables –

Replace if cable is stranding (one of more strands have separated)
