Simrig PRO PSR3 User manual

PRO SIMRIG PSR3
Assembly Instructions
Congratulations, you made the right choice!
Your new PRO SIMRIG is ready to be built, but a few words of advice first:
1. Take your time, it is not a race (that comes later!). Get each step perfect and it will minimise the
adjustments you need to do later.
2. Be careful not to scratch the profile. Careful assembly can mean zero marks or scratches and it will
stay looking great for a really long time.
3. Construct your rig in this order:
a. Base frame first
b. Seat (with brackets / slider). Take time to sit in the rig and appreciate the position. Do not
rush to the next stage. Get this right, as everything you do after this depends on the seating
position staying the same.
c. Pedal section and pedals. Again, take time to sit in the rig. Actuate the pedals. Make sur the
feel is right and that you aren’t too cramped, or too extended.
d. Steering section last

4. It is sometimes useful to leave the plastic end covers / caps until the end of the entire build. These will
be tight fitting, so consider using a soft mallet to put them in place.

Base Frame Section

Parts list:
2 x 80x1350mm profiles
2 x 80x490mm profiles
Covers for Corner Brackets

Arrange the profiles like this. Once you have finished this step, you will have attached 8 angle
brackets securely like this:

To attach each piece, you will use angle brackets, fixed with t-slot nuts and bolts.
Place the t-slot nut into the channel, attach the corner bracket, and tighten with an M8x16mm bolt.
Tighten only loosely to begin with, until everything is straight and true. Once it is, you can tighten
them. You may need to come back and loosen these bolts if you struggle to mount the pedal section
as it can be very tight (the tolerances are very tight to maintain rigidity).
Never over tighten any bolt. Use normal allen/hex keys. Do not use ratchet drivers or power tools as
you will most likely overtighten and damage the bolts and/or t-slot nuts.
Once you have tightened each bolt for the final time, attach the covers.

If you are fitting feet or wheels to your rig, it is advisable to do so at this point before moving to the
next step.
Seat rails fitment:
The seat rails will need to be spaced evenly based upon your seat/seat bracket/seat slider width.
It is advised to mount the seat brackets / seat slider to the seat FIRST, before then attaching these
rails.
Sometimes it is easier to also attach the rails to the seat before locating them on the rig.

If you are using a seat slider, these rails need to be parallel to get a smooth action on the seat slider.
Some seats are narrower at the back than the front (or vice versa) and so need to be ‘spaced’using
spacers / washers to ensure a parallel seat rail.
Parts list:
2 x 40x500mm profiles

Do not be concerned about this technique. These corner brackets were designed to have breakable
tabs for this exact reason.
Attach all 4 brackets in the orientation shown.
(Note: image shows 160mm profile, not 80mm profile, we stole this image from the PSR1 manual!)

Pedal Section
Top-down view. The profiles can be adjusted independently forward and back for different spacing
on your pedal bracket / baseplate.
For pedals that mount from underneath, you will need to use 40x40 angle brackets to attach to the
profiles before bolting to your pedals.

Side view
3D view

Parts list:
2 x 80x470mm profiles. The holes will be threaded on both ends.
2 x Pedal Brackets
8 x M8x25mm countersunk bolts

Ensure that the countersink side of the bracket is facing outwards before assembly. The flat side of
the bracket should be towards the profiles.
Lightly screw in the bolts.
Adjust to the correct width / gap required to mount your pedals.
Mount your pedals. Doing this now will make it easier. It will also allow you to get a good
perspective on where to mount the pedal section itself. Please refer to your pedal manufacturer’s
installation guide on how to correctly mount your pedals.
Finally tighten the countersunk bolts so that everything is secure and in one piece.

The pedal section can be mounted either to the top or bottom channel in this orientation to give
additional pedal height.

Or they can be inverted to sit on the floor.
4 x M8x20 buttonhead bolts
4 x M8 t-slot nuts

Determine how you want to mount your pedal section.
Place the t-slot nuts in the correct channel, 2 per side.

T-slot nuts are shown in place.

Place the pedal bracket in place. You may need to loosen the base frame bolts if it is too tight to
place the pedal section.
Screw in the bolts loosely. Get the desired angle on the pedal section. Tighten the bolts.

Correctly assembled pedal section.

Steering Section
Sideways adjustable. Adjust the two vertical steering wheel aluminium profile, so the length from
the Sim-Racings seat to steering wheel fits your needs.
Parts list:
2 x 80x740mm profiles
2 x 80x100mm profiles
