1. Introduction
1.1 Shaft alignment overview
Shaft misalignment is one of the most significant and most preventable contributors to premature machine
failure.
When a machine is placed in service with less than optimal shaft alignment, the following conditions are likely:
• Poor machine performance
• Increased power consumption
• Increased noise and vibration
• Premature bearing wear
• Accelerated deterioration of gaskets, packing, and mechanical seals
• Higher coupling wear rates
• Increased unplanned downtime
Proper alignment is achieved when the centrelines of each shaft are co-linear when the machine is under load
and at normal operating temperatures. This is often referred to as shaft-to-shaft alignment.
If the shafts of a machine train are not co-linear, when the machine is in operation, they are misaligned.
In essence, the objective is to have a straight line through the centres of all of the shafts of the machines.
The SKF Shaft Alignment Tool TKSA 31/41 is a laser shaft alignment tool that allows an easy and accurate
method for aligning the shafts of a driving machine (eg electric motor) and a driven machine (eg. pump).

5SKF TKSA 31 & TKSA 41
1.2 Principle of operation
The TKSA 31/41 uses two measuring units (MU) both provided with a laser diode and a CCD detector.
As the shafts are rotated through 180° any parallel or angular misalignment causes the two laser lines to
deflect from their initial relative position.
The measurements from the two detectors are used to automatically calculate the misalignment and guide the
user through the vertical (shimming) and horizontal correction steps.
The measurements can be taken according to the 9-12-3 method or with a free measurement method on the
TKSA 41. Measurements can also be taken automatically without action from the user on the Display Unit.
The TKSA 41 can be used with the display flat on the floor or vertical.
The screen orientation will adapt to the display unit orientation.
Results can be saved on a PDF report and exported on a USB stick.

2. Getting started
2.1 Mounting the V-brackets
Use the V-brackets to attach the measuring units (MU) to the shafts.
Make sure the unit marked “M” is attached to the Moveable machine and the unit marked “S”
to the Stationary machine.
If it is not possible to attach the V-brackets directly to the shafts (e.g. in case of space problems) the fixtures can
be attached to the coupling.
For shafts with diameter < 40 mm (< 1.5”) hook the chain to the anchor
in the V-bracket from the inside.
The tightening knob should use the space closer to the rod.
For larger diameters hook the chain from the outside.
Remove the slack of the chain and tighten it firmly with the tensioning
knobs with the rod tensioning bar.
Make sure the rods are firmly tightened to the brackets before mounting the measuring units.
Make sure the measuring units are firmly tightened on the rods and DO NOT lie on bracket.
Brackets are symmetric, they can be mounted either way.

2.2 Switching on the display unit
Press the red On/Off button on the display unit (DU)
for > 1 sec.
The unit is fully started when it reaches the home
screen.
Short press the red On/Off button on the
display unit to:
• Start the DU.
• Put the DU in stand-by.
• Wake-up the DU from stand-by.
Note:
To restart/reset the unit, keep the On/Off button
pressed until the display unit switches off (~6 seconds).
• The DU will enter deep sleep after 2 hours of
inactivity.
• The DU will never turn off during an
alignment job.
•
The Display Unit does NOT need to be
switched off.
Short press for stand-by only.

2.3 Connecting the wireless MU on TKSA 41
The Measuring Units can be connected in bluetooth (wireless) or via the USB cables for charging or in the event
of a power loss.
See next chapter for USB connection.
• Turn On both MU with a short press on the red On/Off button.
• The front LED first indicates the battery status:
• Green = Full
• Amber = Low
• Red = Charge now
• The LED will start blinking in a blue colour to indicate the MU is
trying to connect to the DU.
The Bluetooth symbol appears in the top right corner of the display
next to the “S” and “M” letters.
• The MU will connect automatically to the DU.
When connected, the battery level of the MU is shown.
SM
Note:
• Click on the top right corner (red zone on the right) of the display to
open the MU settings.
• Once connected, the MU LED remains off.
• If the MUs do not connect, check the Troubleshooting section.
• Switch off the MU with a long press on the On/Off button until a
steady red LED appears.

11SKF TKSA 31 & TKSA 41
2.4 Connecting the wired MU on TKSA 31/41
The MU can be connected to the DU via USB cable.
• Make sure the MU are both switched off. (TKSA 41 only).
• Connect the USB cables to the Display Unit.
The USB Symbol on the cable should be facing upwards.
• Connect the Micro USB cables to the Measuring Units.
The locking pins on the connector should be directed
towards the front (laser part) of the MU.
• The MU will automatically connect to the DU.
A USB symbol will be shown next to the “S” and “M” letters.
Note:
• Switch Off the MU before disconnecting the USB cables.
• See section Troubleshooting for any connection issue.
• The micro USB ports on the MU are sealed from the inside and
protected from dust and dirt ingress. SM

2.5 Adjusting the lasers
• Lock the “M” measuring unit (MU) in position.
• Adjust the height of the “S” unit so that its laser line hits the “M” MU in the centre
of the detector, on the red mark.
• Lock firmly the “S” unit in position.
• Use the knob on top of the “M” unit to vertically adjust the laser position on the
“S” unit.

3.3 9-12-3 Measurements
• The measurement type can be selected before starting the alignment via
Settings --> Measurement Settings.
• The analogy of a clock face is used to describe the different measurement positions.
The first position for measurement is the 9 o’clock position, when looking from behind the
moveable machine.
Measurements are to be taken successively in three different positions (9 (-90°)-12 (0°)-3 (+90°)).
• The screen shows the measuring units viewed from the movable machine.
• A triangular wedge will indicate the required position of the measuring units during each step.
1. Turn the shafts to the blue wedge at the 9 o’clock position. (-90°)
2. When positioned within blue wedge the wedge becomes green.
3. Click on the “next” arrow to take a measurement.
4. Turn the shafts to the blue wedge at the 12 o’clock position. (0°)
5. Click on the “next” arrow to take a measurement.
6. Turn the shafts to the blue wedge at the 3 o’clock position. (+90°)
7. Click on the “next” arrow to take a measurement.
Note:
• Do not move or touch the measuring units or the chain V-brackets or their rods during the measurement.
• Do not use the measuring equipment as a handle to turn the shafts.
• Make sure the motor bolts are tightened before starting the measurements.
• The alignment job can be cancelled at any time. SKF --> End Alignment
