4 2 - PRESENTATION GENERAL : You have just acquired a GATES type MC2000 hand operated hydraulic hose and coupling crimping machine. To this effect, it is important that you follow the operating instructions. This MC2000 is specially designed to crimp GATES flexible hose assemblies which are commonly used in industry and agriculture.

5 OPERATING PRINCIPLE: This machine comprises 3 assemblies : the manual hydraulic pump, the crimping head with manual stop and the electrical system PUMP : This provides the hydraulic power required to move the dies during the crimping process. Its characteristics are specially designed to provide the best compromise between available power, die movement speed and ease of handling. Contents and operating principle The pump comprises (see figure 1) : - a hinged lever (1) - a piston (2) - a valve (3) - an oil tank (4) - 2 non-return valves (5) Figure 1 : Schematic diagram of hydraulic circuit 5

6 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 6

7 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) 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) Operating Principle Figure 3 : Electrical diagram 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. 7

8 3 - OPERATING INSTRUCTIONS 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) 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. 8

10 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 ( ) 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. 10

11 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 ( ) - Place die set no. 33 into the machine. - Set the gauge to 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. 11

12 3. 5 POSITION AND FITTING OF THE DIES: In order to crimp GATES couplings correctly onto GATES hoses, it is necessary to adhere to the installation positions of the dies and to the crimping positions below: or Fig. 5 Crimping positions and installation of dies for crimping G and GS type couplings 12

13 4 - SERVICING AND MAINTENANCE MAINTENANCE: 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 ). 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 surface of 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. Figure 6 : Lubrication of the piston cone seatings Figure 7 : Lubrication of the die holder front faces 13

14 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) 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 Figure 8 : Opening the battery tray Figure 9 : Removal of battery from tray REPLACING THE BULB Procedure - Unclip the red protector from the end-of-crimping indicator light - Remove the light bulb and replace with a new one - Clip the red protector for the end-of-crimping indicator light back in place 14
