Drive the vehicle onto a suitable pit and secure using the parking brake

Drive vehicle onto a measuring lifting platform, secure with the parking brake and lift up

Remove lower engine compartment paneling or bottom sections of soundproofing.

MODEL 204, 207, 212, 218 with gasoline engine. See AR61.20-P-1105EW

Prepare vehicle for measurement. The vehicle must be on its wheels for the measurement. Otherwise the measurement will be inaccurate. The transmission mounts and exhaust system must not be stressed during the inclination angle measurement. If necessary, relieve the tension in the transmission suspension or exhaust system.

Prepare articulation angle meter. See AR41.10-P-0086-02P

Check articulation angle meter, adjust if necessary. To check and adjust, see equipmen t operator's manual.

Measure front inclination angle (1). See AR41.10-P-0085-01PA

Measure center inclination angle (2). Measure absolute angle at front and rear propeller shafts. See AR41.10-P-0085-02T

Remove heat sink (4) from rear axle differential (5). Start by removing screw/bolts (6). Bolt, heat sink to end cover

Measure rear inclination angle (3). Measure absolute angle at rear axle housing with propeller shaft inclinometer. See AR41.10-P-0085-03T

Read out all inclination angles (1, 2, 3) from the inclinometer memory. See AR41.10-P-0086-01R . See BE41.10-P-1001-01G , BE41.10-P-1002-01G , BE41.10-P-1003-01G .

Correct front inclination angle (1) at transmission. See AR41.10-P-0086-03CW

According to measurement result. Model 204: see BA22.10-P-1004-03E , BA22.10-P-1005-03E

Correct articulation angle in center (2) on propeller shaft center support bearing. See AR41.10-P-0086-04CW . According to measurement result. Bolt, propeller shaft center support bearing to frame floor assembly: See BA41.40-P-1001-01F

Correct rear articulation angle (3) on rear axle differential. See AR41.10-P-0086-05CW . According to measurement result. Rear axle differential to front adapter See BA35.10-P-1005-01N .

Carry out a check measurement again each time the inclination angle is corrected. See AR41.10-P-0086-01R . Only when inclination angles have been corrected: Model 204: BE41.10-P-1001-01G , BE41.10-P-1002-01G , BE41.10-P-1003-01G .

Install lower engine compartment paneling and bottom sections of soundproofing. See AR61.20-P-1105EW
