Selector finger and control sleeve: adjustment Special tools and workshop equipment required

t  Control sleeve adjustment tool -U-40201-

t  Universal dial gauge bracket -T20020- The selector finger and the control sleeve must be adjusted eccentrically when any of the following components have been replaced: l  Selector finger l  Control sleeve l  Selector rod or its support l  Clutch housing l  Gearbox casing

–  Loosen bolt -1- and separate the slide -A- of tool -U-40201-. –  In the gearbox, measure the diameter of the spherical head of the selector finger. –  Place slide -A- with the same diameter as the spherical head, over the spherical head of the selector finger -B- and secure with the bolt -1- without tightening.

–  Locate tool -U-40201- on the gearbox casing and secure with the two bolts -A-.   Note! t  First remove the slide -A- from tool U-40201 t  Use the hexagon bolts that secure both casings

–  Secure support -T20020- with a dial gauge. –  Locate the end of the dial gauge bracket on the reverse gear rod, with a pre-tension of 1 mm. –  Press the reverse gear control rod in the direction of the arrow and adjust the dial gauge to “0”. –  Pres the reverse gear control rod in the opposite direction and note the reading on the dial gauge (e.g.: 0.70 mm). –  Determine the average value of the movement of the reverse gear control rod by dividing the meaured value by two: average value = 0,70 mm 2 = 0,35

–  Press the control rod from beneath until the average value is obtained (in this case 0.35 mm) and then secure the control rod with bolt -2-.

–  With hook -C- of the tool, move the selector finger towards the inside of the reverse gear track. –  In this position, locate the slide -A- on the tool with the correct spherical head. Fit bolt -1- without tightening.

–  Locate tool -T20020- over tool -U-40201- with a dial gauge. Locate the end of the dial gauge bracket on one side of the spherical head -B-, with a pre-tension of 1 mm. –  Move the spherical head to one side and adjust the gauge to “0”. –  Move the spherical head again to its limit in the opposite direction and note the reading on the dial gauge (e.g.: 0.60 mm). –  Determine the average value of the movement of the selector finger by dividing the obtained measurement by two. average value = 0,60 mm 2 = 0,30 –  Secure the slide with bolt -1- in the position of the value obtained in the former operation (in this case 0.3 mm). –  Remove tool -U-40201- from the gearbox casing.   Note! Do not change the position of the elements of tool -U-40201-. Otherwise the adjuesment of the selector finger and the control sleeve would be wrong.

–  On the clutch housing, loosen bolt -1- that secures the sleeve, until this can move smoothly on the selector rod. –  Locate the selector rod in the central clamp -2-. –  Check that the centring bushes -A- and -B- are located correctly in the clutch housing.

–  Place tool -U-40201- turned 180 °C on the clutch housing.   Note! t  Tool -U-40201- must it perfectly into the two centring bushes of the clutch housing t  The spherical head of the slide -A- must be correctly housed in the control sleeve –  When all the elements are correctly fitted, tighten control sleeve securing bolt -arrow- to the selector rod to 35 Nm. –  Remove tool from clutch housing.
