21.
Quickly rotate the input shaft back and forth. Measurement can start when the shaft moves freely.
Important
Torque meters are extremely sensitive to impact, overload or heavy handling. If you are in the slightest doubt about the setting of the torque meter,
have it calibrated immediately.
22.
Attach the torque meter and rotate it several turns clockwise with even speed. Take the average reading from the meter during rotation, normally
10-30Ncm.
23.
If the reading is higher, or varies significantly during rotation, the synchromesh sleeves or dirt/particles are preventing free movement. Dismantle
the gearbox and establish the cause.
It can sometimes help to mechanically rotate the shaft back and forth under load, but the bearings must be oiled afterwards.
24.
Move the torque meter to the output shaft on the 5th gear nut. NOTE: 5th gear nut must not be engaged. Rotate the torque gauge several times
clockwise with even speed Take the average reading from the gauge during rotation.
25.
Subtract the average reading for the input shaft from the average reading for the output shaft. The calculated tension is a measure of the output
shaft turning torque, normally 50-100 Ncm. Example: reading on the output shaft = 11ONcm and reading on input shaft = 30Ncm gives 110 - 30 =
80Ncm.
^
If average torque is higher, or if it varies significantly, the synchromesh sleeves or dirt particles can be preventing free movement. Dismantle
the gearbox and establish the cause.
If you suspect that the bearings are too tight (over 100Ncm) the gearbox must be dismantled and the collet changed. See Service Manual 4:1
Manual gearbox. The bearings should then be tensioned and test readings should be repeated.
^
If the calculated value is less than 50Ncm, the bearings are too close. If this is the case, tighten the output shaft bearing further in small steps
until the desired reading is achieved.
