Installation Parts

> See end of this

book for model

number breakdown.

STEERING COLUMN MOUNTS:

Most installations will be on the Golf Cart Steering column using
the either the universal mount EXRAY-UBOLT, or optional CNC
6061-T6 Aluminum bracket EXRAY-MEZ. (Optional dashboard
mounting will include separate installation instructions).

Universal Bracket Mount

EXRAY-UBOLT

EXRAY-UXRT

The UBM will t on all column

diameters from 1” to 2”.

Note: Some vehicles have

plastic column cover in­stalled. Some cutting may be
required for secure installa­tion.

The parts shown include
rubber grommets inserted
into the display mounting
holes with 4mmx0.7x12mm
metric screws. Metric Allen
wrenches will be needed.

(See parts sheet)

The RED inserts are inserted
into the rubber grommets as
shown to the right. These are
stops to prevent the screws
from damaging the display.
The RED FLAT BACK is far­thest away from the display.

Universal Bracket Mount:

Lay a soft cloth on the work surface
and lay the display face down. In­stall the Display using the two 4mm x
12mm Allen head screws.

Notice the red at back is the bump

stop, the screws will stop when fully

compressed. The RED FLAT BACK

is farthest away from the display.

> DO NOT OVER TIGHTEN!

Install the pipe clamp onto the steer­ing column.

Position the display 6 inches

(150mm) behind the steering wheel,
about 1 inch (25mm) away from the

steering wheel mounting hub.

Hand tighten the clamp bolt until the

display no longer moves and aligned
straight.

CNC Bracket Mount:

Steering tube column diameters vary between golf cart manufac­turers, ensure you have the correct diameter before starting the

project. (Example: the 1.50” EZ-Go tube uses 1.51” Clamp)

MODELS:

• EXRAY-MEZ EZ-Go 1.51”

• EXRAY-MEZ-EZ RXV 1.59”

• EXRAY-MCC ClubCar 1.66”

• EXRAY-MYAM Yamaha 1.71”

• EXRAY-MCCP ClubCar with

Plastic Tube 1.76”

• EXRAY-MXRT-850E (ELEC)
EXRAY-MXRT-850G (Gas)
ClubCar XRT with Plastic
Tube 1.76”

The parts shown include rubber
grommets inserted into the display
mounting holes 4mm x 12mm met­ric screws. Metric Allen wrenches

will be needed (not included). (See
parts sheet)

The RED inserts are inserted into
the DEEP DRILLED HOLE sec­tion. These are stops to prevent the
screws from damaging the display.

> DO NOT OVER TIGHTEN!

Insert the two 6mmx40mm Allen

head bolts (Cap Screws) with 1-at
washer. (Note bolts may differ from
picture)

Position the display 6 inches

(150mm) behind the steering wheel,
about 1 inch (25mm) away from the

steering wheel mounting hub.

Hand tighten the 6mm bolts until

the display no longer moves and is
straight.

CLUB CAR with plastic tube see next
page. (MCCP and MXRT Models)

Club Car with plastic cover:
(MCCP and MXRT Models)

Tighten the bottom 6mmx40mm
bolts as shown on the previous
page.

Insert the two 6mmx20mm (or
6mmx25mm bolts, which ever

came with your kit) into the
45 degree staking holes. Hand

tight them to just touch the plastic
tube. Then making sure the display
is straight up, 1/4 turn each bolt
side. Do not overtighten.

The display should be inside the
steering wheel window. If the dis­play is too high, move it farther
away down the steering column
and tighten.

Note: Some stainless steering cov­ers differ in size. The tube may
need to be cut to allow the EX-RAY

to t directly onto the steel steering

column. Measure tube diameter.

Steering Column Mount:

Some Club Car models utilized plastic tube covers. The

diameter of the CNC bracket accounts for this tube and uses

45 degree “Stake bolts” which lock the display in place. This
process will “ding” the plastic tube permanently, but neces­sary to lock the display in place.

ELECTRIC MOTOR:

The temperature sensor
monitors the eld coil tem­perature, an indication of
>75°C (167°F), the inter­nal temperature is too hot.

Option 1: Performed by
authorized personnel,
Carefully remove the mo-

tor eld bolt and install the

temp sensor. Install the

bolt and torque to manu­facturers specications.

Option 2: Use the sup-
plied tape, clean the area
with de-grease agent, dry,
and apply the tape over
the sensor and part of the
wire.

Temp Sensor Mount:

Electric Motor: Two options: 1) Motor eld coil bolt or secure
using the included Aluminized tape. (Both methods shown)
Gas Engine: 10mm bolt (optional water jacket sensor avail­able, contact your dealer for more info).

Temp Sensor Installation

18

GAS ENGINE Temp Sensor Installation

GAS MOTOR:

Any bolt near the cylinder
head will provide good
indication. (Preferably a
mounting bolt that does

not require re-torquing the
head bolts).

CAUTION: THE CABLE

MUST NOT CONTACT

MUFFLER EXHAUST

COMPONENTS!

Secure the cable with

cable clamps. Watch for
CHAFFING points that

may damage the cable.

Follow the EXTENSION
CABLE guidelines to prop-

erly route the cable to the
display.

The Golf Cart gas engine Temp Sensor:

The typical installation is for Air Cooled engines. Cylinder

Head temperature is most critical. Oil temperature is also

a good indicator. Find a location that a bolt can safely be
removed and temp sensor can be installed.

19

Temp Sensor EXTENSION Installation

Temp Extension Cable:

Install and use the supplied cable ties to secure the 6 foot
temperature extension cable. Ensure the connectors are
securely attached, do not apply any stress on the wires as the
motor moves up and down.

SPEED Sensor BOLT Installation

BOLT SENSOR - AXLE Mount:

Remove the Drivers side wheel,

SUPPORT WITH SAFETY

JACK

CAUTION: DO NOT PERFORM

THIS PROCEDURE ALONE.

ENSURE A STABLE SAFE

WORK ENVIRONMENT.

Mount the 6mm x 19mm Magnet
bolt. Some brackets may re-

quire the extra 6mm “Jam Nut”.

DO NOT OVER TIGHTEN this

bolt. It only needs to support

its own weight.

Position the Clamp head and

magnet bracket OPPOSITE of

each other onto the wheel hub
and tighten clamp. This will off­set any weight balance.

10mm BOLT SPEED Sensor Installation (Most all):

Speed sensor is a magnet and wheel speed sensor. The sensor
mounted on the steering knuckle and magnet on the rotating

wheel. Various small brackets are supplied best suit your applica­tion. EZ-GO shown below. YAMAHA & ClubCar & Jakes Disc
