PAGE 21
5:3 Camera body 503CW Adjustment Adjustment No. 1 (Overtravel) With the film winding mechanism tensioned, check the angle 15-16o with the bayonet plate tool 904644 pushed hard against the stop arm (13355). Measure the angle with a spring tension of 300 gm/cm. Adjust by altering the position of the bearing bracket (13171). When the correct angle is achieved tighten the screws. Check that meshing between intermediate gear (13167) and the front drive gear is as close as possible without binding. Fig. 33.
PAGE 22
5:4 Camera body 503CW Adjustment Adjustment of the release mechanism Check that the release bar (30375) is free from the signal arm pawl. Adjust by carefully bending the forward part of the signal arm. Use tool V-2200. Minimum free play: 0.2 mm. With the camera fully cocked the release bar should protrude a maximum of 0.9 mm through the rear plate. Adjust this by bending the release arm (13357) using tool V-2224. Fig. 35. 13357 max. 0.9mm min. 0.2 mm 30375 Fig.
PAGE 23
5:5 Camera body 503CW Adjustment The push rod (22369) is adjusted so that it is set 0.15 mm below the release bar (30375) forward angle setting. Check by using the tool V-5942. Adjust by gently bending (22369). Fig. 37. 30375 22369 0.15 mm Fig. 37 Position tool V-5942 as shown and press against the front plate. The mechanism should not release. When the tool is moved upwards the mechanism should release. If a large adjustment is needed bend the release arm (13357) using tool V-2224.
PAGE 24
5:6 Camera body 503CW Adjustment Adjustment of the release sequence Make sure the winding knob V-2206 and the bayonet plate tool 904644 are installed. Release the camera and keep it released by holding the release bar and push rod back. Move the release bar and push rod to the front slowly and observe the closing sequence. Fig. 41. V-2206 904644 1. Key releases to fully released position. 2. Auxiliary shutter closes. Note that the winding knob is blocked all the time until the auxiliary shutter closes.
PAGE 25
5:7 Camera body 503CW Adjustment Operate the winding knob V-2206 to cock the shutter. Check that the bayonet plate tool 904644 is blocked by the stop lever (22769) when the camera is completely cocked. Adjust by bending the front of the lever. The lever engagement should be retained until the camera is fully released. Fig. 44. V-2206 904644 22769 Fig. 44 Fitting the damping ring (22287) Hold the lid (14280) in position and unscrew (822605). Position the damping ring (22287).
PAGE 26
5:8 Camera body 503CW Adjustment Fitting the Circuit board (22575) *22882 CAUTION! When handling the circuit board a grounded bench mat and a wrist strap must be used to prevent ESD damage. Put the insulating plate (22746) in position and place the circuit board on top of it. Secure the board by first fitting the two screws (820015) followed by the attachment (22453). * Note! The circuit board (22882) is fixed to the wall by an insulating double-sided tape, screws and attachment.
PAGE 27
5:9 Camera body 503CW Adjustment Adjust the lower rear plate/shell alignment and tighten the two rear screws (829755)and seal with loctite. Fit and tighten the two front screws (820781). Check the upper edge alignment of rear plate and shell. Adjust, if necessary, the two screws (825760) which are accessible behind the leathers mounted on the shell. Note! The rear edge of the shell must not protrude over the rear plate at any point.
PAGE 28
5:10 Camera body 503CW Adjustment Check the mirror 45o angle using the sighting tube which fits in the holder on the gauge. Tighten the locking screw. Shine a light source towards the oval cut-out in the upper part of the tube so that the white ring of the ocular is illuminated. When the mirror is at 45o the pattern in the sighting tube will appear as shown. Check that the inner white circle is symmetrical and does not lie outside the inner black field.
PAGE 29
5:11 Camera body 503CW Adjustment Check the camera functions. Check that the auxiliary shutter is clear of the internal covers. Check the release sequence using a micrometer V-2354. Mount the micrometer in the exposure button’s cable release socket. Carefully screw in the micrometer’s screw until the camera releases. After releasing it should be possible to turn the micrometer a further 3 to 5 notches before it bottoms. Screw out the micrometer slowly and observe the closing sequence. 1.

5:12 Camera body 503CW Link to: VHABSTS Adjustment Calibration and control of the flash metering system TTL Control/calibration should be carried out each time the camera has been in for repair. The tolerance for the flash meter is ±0.3 EV at all settings. If the Hasselblad Service System 970600 is used, follow the step by step instruction in the STS user manual. Note! For calibration work use ISO 100 and LV15. * (ISO 400/LV12). If the Test box 902474 is used follow the instruction below.
PAGE 31
5:13 Camera body 503CW Adjustment Calibration On pressing the MEASURE button one of the three LED´s will light. The variable resistor in the camera (access behind the leather beside the ISO dial) should be turned so that the green LED lights when the MEASURE button is pressed again. If the red LED lights, the resistor is turned anticlockwise and if the yellow LED lights, it is turned clockwise. At least two seconds must be allowed between measurements.

Place the lens catch lever (103440) in position and fit the cover plate (105107). Secure with screw (823440). Install the spacer (810409) and the spring (816858).
PAGE 33
6:2 Camera body 503CW The hole for the locating pin (812202) is bored with 1.15 mm drill. Use tool V-2211 for driving in the pin. Drive the pin in until the face of the tool touches the front bayonet plate. When a new front plate is installed the hole must be drilled using tool 902658 (V-2075), which is equipped with two drill bushes. Fit the governor (30386) using two screws (820014), ensure the gears mesh and then secure the screws. Remove the swarf and lubricate the bevel gears with grease.
