t
| Renew all safety rings, taking care not to stretch them excessively when fitting. |
t
| The safety rings must be perfectly seated in their groove. |
t
| On fitting split pins, their groove must be longitudinal with respect to the trajectory of the force, as in the illustration. |
t
| Loosen and tighten nuts and bolts on covers and casing in diagonal sequence. |
t
| For delicate parts, e.g. the clutch press, do not tilt them and always loosen the bolts gradually and in diagonal sequence. |
t
| The torque settings refer to non-oiled nuts and bolts. |
t
| All locknuts must be renewed. |
t
| Needle bearings must be fitted with the thickest side plate facing the assembly tool. |
t
| All gearbox bearings will be fitted after having been lubricated with gearbox oil. Lubricate with special care to measure friction torque. |
t
| Bearings corresponding to the same shaft will be all replaced together. Use bearings from the same manufacturer as far as possible. |
t
| Bearings should be heated to 100 °C approx. before fitting. Use electric blower -SAT 1416- and the digital thermometer -SAT 4002- to check temperature. |
t
| Do not mix external tracks of the same size bearings, they are matched pairs. |
t
| Before fitting shims, check thickness measuring several points of the surface with a micrometer. |
t
| The existence of different thickness shims will enable the selection of the right one for the application. |
t
| Shims must not have lips or be damaged. |
t
| Only fit shims in perfect state. |
t
| Do not mix up rings from different gears. If they are to be re-used, always fit to the same gear they came from. |
t
| Check for wear and replace if necessary. |
t
| On fitting coat with gearbox oil. |
t
| Before fitting clean thoroughly. First heat to 100 °C approx. Use electric blower-SAT 4002- and the digital thermometer -SAT 4002- to check temperature |
Removal of outer rings of roller bearings and bearing bushes with tool set -T20140- |
Remove the outer rings of the roller bearings or the bearing bushes as follows: |
–
| Measure (if possible) the internal diameter of the external ring of the roller bearing or the bearing bush. |
–
| Select the correct clamp from the tool set according to: |
If the diameter measured is less than 30 mm: |
–
| Fit the plunger for small clamps/10 and the correct clamp for internal diameters. |
If the diameter measured is more than 30mm: |
–
| Fit the plunger/28 and /29 and the correct claws for the internal diameter. |
–
| Screw the nut /5 and washer on the plunger. |
–
| Place the tool on the outer ring of the roller bearing or the bearing bush and fit the threaded legs so that they are firmly secured. |
