2. 3. 2 - CRIMPING HEAD:
This is the most technical part of the crimper. With the aid of its dies, it allows the
coupling to be crimped onto the flexible hose.
It comprises the following elements (see figure 2):
- crimping head body (6) - sets of dies (7)
- a hollow piston moved by the oil pressure (8) - eight return springs (5)
- a crimping head flange (3) - a micrometer gauge unit (18)
- a die holder (4)
Figure 2 : Schematic diagram of crimping head and micrometer gauge

MC2000 USER GUIDE

Operating Principle
The kinematic crimping principle consists of transforming a rectilinear displacement, i.e.
that of the piston (8), into a radial displacement thus ensuring the crimping process by way
of the dies (7).
Mechanical bonding is achieved through the friction on a slope and a face on the barrel
clamp (3) and a slope (cone) on the piston (8) and the die holders (4). The die holders are
kept together during their travel by means of a spring arrangement.
The main components are made of a special steel and have been subjected to a series of
thermal body and surface treatments, so that they can resist the large loads and wear
through friction is prevented.
Precise guiding is ensured by means of two Teflon-Bronze bearers on the piston (14 & 17).
The piston is sealed by means of two O-rings + anti-extrusion bushes (15 & 16)
2. 3. 3 - THE ELECTRICAL SYSTEM
This system provides the supply power for the end-of-crimping indicator light
It comprises the following elements (see figure 3) :
- a micro-switch (1) - a 9V battery type 6 LR 61 (3)
- a red indicator light (2) - a test push-button (4)
Figure 3 : Electrical diagram
Operating Principle
This system indicates to the operator, by way of a light signal, that the set value on the
micrometer gauge has been reached, i.e. that the final crimping diameter has been attained.

3 - OPERATING INSTRUCTIONS
3. 1 - SAFETY:
Safety glasses must be worn during machine operation.
The crimper must be positioned on a stable bench or frame.
Do not put your hand in the crimping head during its operation.
Do not alter the technical characteristics of the crimper (pressure and other parameters).
3. 2 - UNPACKING - INSTALLATION :
Unpack the machine without destroying the packaging. The machine can only be transported or
received at a later point in time if it is inside its original packaging. Ensure therefore that the
packaging is not damaged when opening it, so that it can be stored.
Lift the box cover, then remove the screws positioned at the bottom of the packaging uprights,
remove the uprights from the box. The crimper is now accessible and can be taken out.
Never hold the machine by its crimping head or by any of its components.
For optimum use and reduced operator fatigue, it is recommended that the crimper is positioned
horizontally on a bench at a height of approximately 0.75m.
Once the machine has been placed on its support, fit the pump handle by inserting it into its
socket situated at the top of the pump body. Secure with butterfly screw.
The warranty will be void if the above unpacking and/or installation procedures are not
followed.

3. 3 - COMMISSIONING - OPERATION:
Ref: Figure 4 page 9
- To prepare the machine for crimping, open vent on hand pump by turning the knurled cap
anti-clockwise approx. one full turn until the cap becomes free. (Cap must be tightened
during transit).
N.B. Only remove cap completely when pump requires ‘topping up’ with oil.
-Close the pressure release valve by turning the release valve knob on the hand pump a
clockwise direction (hand tighten only).
-Retract the die holder by opening the valve (1) (anti-clockwise).
- Place the set of dies corresponding to the crimping operation that is required (see Equipment
User Pack - CD).
-Display the value corresponding to the crimping operation that is required on the digital
readout of the gauge (4) (see Equipment User Pack - CD).
- Press the test button (5) to check the battery (6) is not flat and that the indicator light (7)
works correctly.
-Place the hose together with its coupling inside the crimping head (8), whilst respecting the
position of the coupling in relation to the dies if necessary (see Equipment User Pack - CD).
- Close the valve (1) (clockwise).
-Carry out the crimping operation by activating the pump handle (9).
- Stop the crimping process when the indicator light (7) is illuminated.
- Open the valve (1) (anti-clockwise) to open the dies and release the flexible hose assembly.
-Check the crimping diameter with a vernier caliper (7369-0322) and compare the measured
value with the value published in the Equipment User Pack - CD.
A 7 unit variation on the gauge digital readout allows the crimping diameter to vary by
0.1 mm
The gauge values are only provided as a guide to assist in manufacture, only the exact
crimping diameter can guarantee the flexible hose. It is imperative that the diameters
obtained are within the tolerances specified by GATES.

3. 4 - CALIBRATION:
Each machine is factory-calibrated and is ready to operate on delivery. However, the crimper
must be tested each month and whenever the crimped diameter does not match the specified
diameter. The calibration procedure is as follows:
Calibrate using –08 Megacrimp calibration shell 8G (7482-19860-5)
- Place die set no. 33 into the machine.
- Set the gauge to 200.
- Crimp the calibration shell.
- Measure the calibration shell diameter - it should be 26.0mm +/- 0.25mm.
- If the crimped diameter matches the specified diameter, the machine is properly calibrated
-If the crimped diameter does not match the specified diameter, it is necessary to
calibrate the machine as follows:
1 - Calculate in millimeters the difference between the crimped diameter and the
calibration diameter of 26.0 mm
2 - Open the crimping head to its maximum
3 - Unscrew the two M6 screws which hold the stop strip on the back of the piston
(Fig. 2 / 2) then remove the strip (Fig. 2 / 13).
4 - Calibrate the machine using the M6 screw (Fig. 5 / 3) positioned on the strip itself
as follows:
- Measure the dimension (Fig. 5 / 1) of the screw head relative to the strip
Figure 5 : stop strip
- Release the locknut (Fig. 5 / 2)
- Adjust screw (Fig. 5 / 3) by screwing (clockwise) to reduce the crimping
diameter or unscrewing (anti-clockwise) to increase the crimping diameter.
Caution: One turn of the screw or a 1mm change in the dimension
(Fig. 5 / 1) alters the crimping diameter by 0.65 mm
5 - Tighten the locknut (Fig. 5 / 2)
6 - Replace the stop strip at the back using the two M6 screws.
- Crimp another standard calibration shell (-08 MegaCrimp shell) and check the crimping
diameter obtained.
- Recalibrate the machine as described above if the crimping diameter obtained is still
incorrect.

4 - SERVICING AND MAINTENANCE
4. 1 - MAINTENANCE:
4. 1. 1 - DIE HOLDER LUBRICATION
The low friction of the piston on the die holders when crimping is very important. For this
reason, it is necessary to lubricate between the die holder and the piston at regular
intervals. An insufficiently lubricated machine may lead to the piston and the die holders
seizing-up or being damaged. For an effective lubrication, it is very important to apply a
60% concentrated grease with molybdenum bisulfide (this product is provided with the
machine and is available from GATES – 7482-19957).
Lubricate after every 100 crimping operations as indicated below :
Procedure
Lift the back of the die holders from the piston cone, using the lubricating tool provided
(see figure 7) and wipe each of the 8 die holder seatings and the conical surfaceof the
piston. Apply the new grease to this surface using a brush. Also lubricate the die holders’
front face after closing them as far as possible (see figure 8).
Caution: Never use a degreasing agent to remove the old grease from the machine.

4. 1. 2 – CHECKING AND REPLACING THE OIL
Replace the pump oil once a year.
Procedure: Ref : Figure 4 page 9
- Open the valve (1) on the pump to allow maximum piston back stroke
- Unscrew the filler cap (10) and drain the oil by tilting the machine
- Fill the tank up with new oil (ISO VG 22 recommended) until the level is 5mm from the
top of the tank
- Refit filler cap (10)
4. 1. 3 – REPLACING THE BATTERY
The end-of-crimping indicator light operates by way of a type 6LR 61, 9 Volt battery
Procedure
- Using the lubrication tool, apply slight pressure onto the battery casing tray
- Pull the tray to free the battery
- Replace the 6LR 61 battery, then replace the tray, ensuring correct polarity
