Takata Racing RACE 4 SNAP - Manual (Page 5)

Incorrect wrap techniques or positioning 3-bar slides too far away
from the roll cage bar or from any bracket may allow webbing to
slide or slip during an accident. Extra elongation will occur which
may reduce the effectiveness of the racing harness and the Head
and Neck Support, if worn. Shoulder belts may slide off the Head and
Neck Support or will lengthen allowing the head and chest to impact
onto the steering wheel. Severe injuries or death may occur.

1. position D-Ring to roll bar with wider bar atop
2. slide a minimum of 600mm (24”) of strap length through D-Ring and from
underneath around roll bar [first loop]
3. slide strap from atop through D-Ring slot towards roll bar and back between
roll bar and first loop until it protrudes from slot in D-Ring (second loop).
4. Pull at shoulder belt to check that wrap will tighten when being loaded.
5. Wrap strap end around roll bar again [third loop] and thread through D-Ring
again. Shoulder belt is now sandwiched between first loop webbing and
protruding strap end.
6. Make sure strap end protrudes at least 100 mm [4”]

This light weight system assembles directly to 50 mm (2”) slot brackets and is
therefore commonly used by TAKATA for anti-sub strap brackets. This system is
also absolutely micro slip free.
W RAPPING INSTRUCTIONS
1. Place LV 4 with its thicker bar onto the bracket.
2. Run strap end through slot at LV 4
and then from underneath through
webbing slot at bracket. Pull
through at least 200 mm (8”) of
webbing. Fold strap end over the
wider bar of LV 4 and back through
the gap between bracket bar and
LV 4 bar.
3. Slide strap end further through the
webbing slot at bracket and then
fold the strap end through the slot
at LV 4.
4. Pull at the load taking strap and the bracket to make sure, the webbing is
properly clamped by the wrap hardware.
5. If this is not achieved, check for proper strap routing and follow these
instructions step by step again.
6. If the protruding webbing is significant
longer than the minimum of 50 mm
[2”], you may fold it over again, run it
through webbing slot of the
bracket/latch and again back and
through the webbing slot at LV 4.
7. In this case, the strap end now protrudes from the down side of the LV 4.
Webbing m ust be wrapped tightly!
E YE B OLT INSTALLATION FOR S NAP -O N B RACKETS
• Assemble eye bolt and spring washer as shown in sketch
beside.
•
Bolt in eye bolt and tighten securely. The optimum torque
setting is 40 Nm (350 lbs./inch). Pull either screw driver or
similar tool through eye and turn clockwise to tighten the
bolt securely.
•
Make sure the eye’s ring is pointing in direction of pull as shown in drawing
below. This position will reduce the risk of unintended loosening of the eye
bolt by torque forces applied by the harness during racing. If you cannot
achieve this position by further tightening or loosening the bolt by a maximum
of ¼ turn, dismount the eyebolt and use 2 spring washers to come closer to
the recommended position.
Safe harness belt functioning requires belt and bracket alignment
during a crash. Any restriction of the harness belt or bracket may cause
the webbing dumping/loading into bracket edges and webbing may
become cut and may cause severely injuries or death.
Never try to drill a larger bolt hole into any bracket. The bracket may be
weakened or stick to your drill bit and the bracket and attached webbing
and its hardware may spin and may cause severely injuries or death.
