Getting started
Mounting the motor on the simulator
Simucube 2 must always be rigidly mounted on the simulator rig for user safety.
Mounting option 1
Simucube 2 can be mounted with separate bracket that can convert the front mount to a
horizontal platform (table) mounting as in Figure 3. Mounting brackets be found from Simucube
resellers listed on https://www.simucu.be website.
Figure 3 Mounting Simucube 2 using a mounting bracket.
Mount Simucube 2 as shown in Figure 3. Sport and Pro models are mounted with 30mm M8 bolts
with 1.25mm thread pitch (1) and M8 flat washers (2). Simucube 2 Ultimate is mounted through-
the motor flange with 40mm M8 bolts (1), M8 flat washers (2) and M8 locking nuts (3).

Mounting option 2
Simucube 2 can be mounted by utilizing a front mount bracket found on many simulator rigs as
shown in Figure 4.

the motor flange with 40mm M8 bolts (1), M8 flat washers (2) and M8 locking nuts (3).

Wiring
Read and understand this chapter fully. Do not operate the product if you haven’t fully read
or understood this document. Check that main power switch at the back is off and all cables
are unplugged before proceeding.
Connect the cables as indicated in figures 5 and 6. Important: always connect the AC power
supplies first to Simucube (connection 3) and only then to AC mains socket (4).
Figure 5 Simucube 2 Sport and Pro wiring diagram.
Note: Simucube 2 Sport has one power supply, and Simucube 2 Pro has two power supplies.
Figure 6 Simucube 2 Ultimate wiring diagram. Use Simucube 2 Ultimate only in a professional environment.

Antenna installation
(1) Locate the antenna connector at the back of your Simucube 2 wheel base.
(2) Take the supplied antenna (Disclaimer: use ONLY the supplied antenna) and insert it into the
antenna connector. Make sure you are inserting it in a straight orientation. Gently twist the
knurled surface at the end of the antenna in clockwise direction approximately 3 turns. DO NOT
use any tools in the installation, only screw the antenna in place with your fingers.
You can now use the joint in the antenna to adjust antenna so that it is not in the way of other
connectors/obstacles. In normal usage the orientation has little effect to received signal strength.
The signal strength can be checked in the True Drive software.

Checklist for the first use
1. Connect remote Torque off button box to Simucube 2’s TORQUE OFF connector.
2. Connect USB cable from Simucube 2 to PC.
3. Connect power supply/supplies to Simucube 2 POWER IN connectors.
Important:
1. Always connect POWER IN connector(s) on
Simucube 2 first before connecting power supply
to the AC outlet.
2. Both power supplies must be used for Simucube
2 Pro.
3. Simucube 2 Ultimate is to be used only in a
professional environment.
4. Connect power supply/supplies to 110 - 240 V AC outlet with protective earth (PE).
5. Fix steering wheel (not included) to Simucube Quick Release™ (SQR™). If required, install
Spacer and/or 70 mm Adapter between the SQR wheel side part and the wheel.
6. Download and install True Drive software from https://simucu.be website. This product
will not fully operate without installing the software for safety reasons.

Simucube Quick Release (SQR) User Guide
SQR –Wheel side assembly
Figure 7 SQR assembly options
The included wheel side SQR (Simucube Quick Release) system can be assembled in multiple
configurations to best suit your wheel and button box combination.
Standard configurations (Figure 7) include (1) 50.8 mm PCD (pitch circle diameter) front
mounting without the spacer, (2) 50.8 mm PCD front and back mounting with the spacer and
(3+4) 70 mm PCD front and back mounting.

SQR –50.8 mm PCD front mounting, no spacer
It is possible to use the SQR without a spacer, but the use of the spacer is recommended as it gives
the user more space to use the locking pin. To attach the wheel side plate to your wheel, use
suitable M5 screws and washers (3 or 6 screws depending on your wheel type) from the included
ones or use your own if suitable length is not found. In case you have a need to find longer/shorter
screws, the correct screw thread type is M5 size with 0.8 mm pitch.

SQR –50.8 mm PCD front and rear mounting, with spacer
To rear-mount your wheel (if you have threads in the rear of your wheel/button box), you will
need 3 or 6 M5 screws with a length depending on your wheel and button box thickness and 1
washer per screw. Align the four middle threaded holes as in the image and attach the screws in
the order as illustrated.
Use four of the included 10mm long M5 screws and 4 washers to attach the wheel side plate to
the spacer as illustrated. Note: Do not use excessive torque to avoid damaging the threads in the
SQR aluminum parts.

To front-mount your wheel, you will need 3 or 6 M5 screws and a washer per screw. The right
length for these screws is approximately 35-39mm + the thickness of your wheel and button box
since the screws attach to the threads in the wheel side plate.
Use four of the included 10mm long M5 screws and 4 washers to attach the wheel side plate to
the spacer as illustrated. Align the four middle threaded holes as in the image and attach the rest
of the screws as illustrated.
Completed SQR setup for 50.8 mm PCD wheel.

SQR –70 mm PCD front and rear mounting, with spacer
To front-mount your wheel, you need 6 M5 screws with a length depending on your wheel and
button box thickness, 2 washers per screw and 1 locking nut per screw. Align the eight middle
threaded holes as in the image and attach the screws in the order as illustrated.
To rear-mount your wheel (if you have threads in the rear of your wheel/button box), you will
need 6 M5 screws with a length depending on your wheel and button box thickness and 1 washer
per screw. Align the eight middle threaded holes as in the image and attach the screws in the
order as illustrated.

In both cases use four of the included 25 mm long M5 screws and 4 washers to attach the wheel
side plate to the spacer as illustrated. Note: Do not use excessive torque to avoid damaging the
threads in the SQR aluminum parts.
In both cases use four of the included 10 mm long M5 screws and 4 washers to attach the wheel
side plate to the spacer as illustrated. Note: Do not use excessive torque to avoid damaging the
threads in the SQR aluminum parts.

Completed SQR setup for 70 mm PCD wheel.
SQR –70 mm PCD with no spacer
Due to the diameter of the wheel side SQR plate, use of the 70 mm adapter without the spacer is
not possible with the included hardware.

SQR –Motor side assembly
When installing the SQR (Simucube Quick Release) system ensure that the motor shaft diameter
is compatible with the SQR.
The SQR motor side can be disassembled and re-installed in case of slipping or other problems
relating to tightness, or if for some reason the black hub has slipped too close to the motor and
appears to be touching it.
SQR –Quick Release Pin adjustment
The tightness of release pin can be adjusted. Video guide: youtube.com/watch?v=YYKkb5Ioadg
Motor side disassembly
Open the three bolts on the top of SQR and remove the motor side plate.
If you do not want to lose the SQR position, draw some markings to remember the SQR position
related to the motor shaft.
Open the four cone clamp bolts and remove the cone clamp and the SQR outer tube. If the cone
clamp can’t be removed after opening the four bolts, it can be opened by screwing one or two
cone clamp bolts to the two empty threaded holes.
