Step 2:
With the seat tilt mechanism handle closest to you, remove
the screws holding the scantling plate from each side.
Then remove the scantling plates and place them aside.
Start by removing the seat unit from your size 1 Sharky, release the
seat unit by pressing down the red levers at the front on each side.
Tilt the seat unit back and lift to remove.
Place to one side.
Step 3:
Now you need to remove the main bolt from each side of the tilting
unit using a 4mm hex/allen key and a 10mm open ended spanner.
Loosen and remove both bolts, nuts and washers completely from
the frame.

Removing the Tilting Unit
Step 4:
With the bolts completely removed, you will now be able to spread
the main frame and pop the tilting unit o each side mount.
To remove it completely from the frame you will need to pull up
on the pin release cable to release the pins and lift the complete
assembly o the frame.
Step 5:
This now leaves you with the blue scantling plates visible on each side.
Remove the 3x M6 bolts holding the plate and spacer block on each side.
These are the spacers and long M6 bolts that will NOT be used
to reassemble/convert to the size 2 unit. Place these aside.

Identifying the required parts
The above image shows the original parts needed to refit to the size 1 Sharky base to convert
it to a size 2, along with the new size 2 tilt mechanism and the 6x M6 x 28mm bolts.
These are the parts to reassemble before fitting the size 2 tilt mechanism.

Step 6:
Place the M6 x 28mm bolts in the scantling plates and start each bolt
thread in the main base frame.
Step 7:
Then tighten all 6x bolts to hold the scantling plates in place.
Step 8:
While holding the new size 2 tilt mechanism,
place it between both mount points and spread
the frame to position the mounts and tilt
mechanism together.
Step 9:
Now fit the original long bolts, washers, and nuts to the tilt mechanism
to secure this to the main frame. Tighten the bolts and nuts to be firm,
and not over tight which may impede the tilting mechanism.

You will find it helps to pull the cable to release the pins
in the tilt mechanism.

Step 10:
Fit the tilt guide plates and screws to each side of the tilt mechanism.
This completes the procedure, and you can now fit the size 2 seat unit to the base frame.
Check the tilting mechanism slides smoothly and the locking pins engage in every position.
If the guide plates bind you need to add a washer between the plate and the frame.
