Diamond Wheel - Complete braked wheel kit

On receipt of a rim kit, visually check the integrity of the packaging.

Do not use blades longer than 5mm for unpacking.

Each hub or spindle is mounted on a wooden support to hold the rims in place during transport. Unscrew the KM5 nut and lock washer to remove the wheel from the spindle. A simple axial effort is required to remove the wheel from the stub axle. Remove the screws holding the stub axle to the wooden panel to free the assemblies from this support, which is only used for transport.

Remove the rim from the shaft by unscrewing the KM5 nut and MB5 lock washer, then pull the rim axially off the shaft. The brake disc must remain in place in the brake calipers.

Separate the rim by removing the 6 M6 screws that bind the two rim halves together. For transport purposes, only two of these screws are moderately tightened.

Before installing the tire, apply tire grease to the tire and the part of the rim that will be in contact with the tire.

Insert the inner tube into the tire.

Position the tire with inner tube on the outer rim half, the one with the valve hole.

Passez la valve à travers l’orifice de la demi jante.

Aidez-vous de l’outil de fermeture de jante Evoskil ou de l’arbre de la fusée pour garantir l’alignement axial de l’ensemble.

Install the bearing spacer on the shaft. This spacer is then fitted between the two bearings. Caution: this spacer is tapered, so match the bearing and spacer diameters.

Place the rim half with the tire on the rim closing tool.

Push the second rim half onto the shaft until it touches the tire.

Fit M6*20 CHC screws + 2 washers + nylstop nut to close the rim.

Install the 6 screws and 6 nuts by hand before tightening. The screws supplied are lubricated to prevent the screw/nut seizure common on stainless steel.

If your tire is too wide to easily close the rim with the CHC M6*20 screws supplied, use 2 M6 screws of sufficient length diametrically opposed to pre-close the rim before fitting the 4 screws supplied in the holes available. You can then remove the 2 temporary screws and fit the last 2 M6*20 CHC screws supplied.

Then tighten the 6 staggered bolts to 7Nm.

Inflate the tire, 3.5 bar max.

The tire should rest easily on the rim sidewall, and we recommend removing the valve obus for the first inflation.

Assurez-vous au préalable de la correspondance de l’entre axe de fixation fusée/train. Cet entre axe est de 40mm au carré sur l’embase standard Evoskil.

Position the stub axle on the undercarriage, preferably with the brake-hose port facing upwards. Vertical mounting is possible. However, a downward-mounted orifice will make it very difficult to bleed the circuit.

Assemblez la fusée au train avec 4 vis M8 classe 8.8 minimum de longueur adaptée à l’épaisseur de votre train. Ces vis doivent dépasser de 13mm de la jambe de train afin de traverser l’intégralité de l’embase de la fusée. Ces vis ne doivent pas dépasser de plus de 20mm de la jambe de train.

The use of washers adapted to the material of your strut, coupled with a medium threadlocker, will guarantee the stability of this assembly.

Remember to degrease any glued parts.

Tighten the 4 screws to a torque of 18Nm.

Your brake line coming from the master cylinder must end in a Ø10.2mm banjo.

Mount this conduit on the double banjo bolt side, stacking joint/airplane conduit/joint/connecting conduit/joint.

Hold the conduits so as not to twist them when tightening the banjos.

Tighten banjo bolts to 25Nm.

Use DOT4 brake fluid.

Depending on your installation (hose routing, tee, limiter, etc.) and your master cylinder, bleeding can be done by pushing the fluid through the master cylinder or through the calipers.

We recommend bleeding by pushing brake fluid through the bleed nipples on the calipers.

Take care not to spill brake fluid on any parts, especially the brake pads. Solvent cleaning is necessary after bleeding.

We recommend using a Ø12.7 to 17mm master cylinder. The smaller the master cylinder diameter, the more powerful the braking effect. The lower limit of the emitter piston diameter is the lever stroke, which should allow strong braking before the stop (with perfect bleeding).

The calipers are tested up to 140bars, but a maximum pressure of 80bars is recommended. This pressure is more than sufficient for light vehicles. In practice, a pressure of 10 to 20 bars is required for normal braking, while a pressure of around 40 bars is generally sufficient to lock the wheels on dry grass, compared with around 60 bars on hard ground (variable according to tires and machine weight).

Place the wheel (with the stainless steel studs facing the axle) on the axle and press gently until the brake disc is ready to receive the studs. Align the brake disc so that the pins on the rim all face the slots on the disc.

Push in the rim until the bearing stops.

The brake disc must be axially free on the pins. It is the brake pads which (once the system has been bled) hold the disc axially.

Fit the MB5 washer and KM5 nut.

Tighten the KM5 nut moderately and lock the MB5 washer by folding a tab into a slot in the nut.

Your assembly is now complete. Remember, it's important to follow these steps carefully to ensure the performance and safety of your rim kit. Always make sure all parts are tight and in place before using your unit.

We strongly advise you to replace the bolts and nuts with new ones every time you install a new product, especially the safety systems (MB5 washer and nylstop nut).
