| t
| The safety rings must fit perfectly into the bottom of the insertion slot. |
| t
| Always replace the elastic guide pins. |
| t
| When assembling the plastic guide pins, their slot must be positioned longitudinally with respect to the direction of the drive, as shown in the figure. |
| t
| Always loosen and tighten the bolts and nuts in a cross-shape for attaching covers and casings. |
| t
| With delicate parts, such as, for example, the clutch press, do not tilt them and carry out the operation gradually. |
| t
| Self-locking bolts and nuts must always be replaced |
| t
| When new conical bearings are assembled, they shall be assembled as they arrive, without greasing. |
| t
| The needle bearings must be assembled with the thickest side of the plate facing towards the assembly axle-tool. |
| t
| All the bearings for the gearbox must be put into place slightly oiled for the gears. Take special care when oiling them for the friction torque measurements. |
| t
| The bearings belonging to the same shaft must be replaced together. Use parts from the same manufacturer as far as possible. |
| t
| For putting the bearings into place, they must first be heated to a temperature of approximately 100 °C. Use the electrical blower -SAT 1416- and the digital thermometer -SAT 4002- to check the temperature. |
| t
| Do not confuse or exchange the outer tracks for the bearings of the same size; the bearings come in pairs. |
| t
| Before assembling the adjustment washers, their thickness must be checked by measuring them with a micrometer at several points on their surface |
| t
| The presence of washers with different tolerances allows the precise thickness of the washer that is needed to be achieved. |
| t
| The washers must not have rough edges or defects. |
| t
| Assemble only adjustment washers that are in perfect condition. |
| t
| Do not mix synchronising rings together with different gears. If they must be used again, place them in the same gear as before. |
| t
| Check them for wear and replace them if necessary. |
| t
| For their assembly, cover them with oil for gears. |
| t
| Before assembling them, clean them very carefully. They must first be heated to a temperature of approximately 100 °C. Use the electrical blower -SAT 1416- and the digital thermometer -SAT 4002- to check the temperature. |
| t
| New gearbox code letters have been introduced, with a new mineral gear oil -API GL4 SAE 75W- according to standard TL 726 /Y (hypoid oil) This type of oil must only be used in the specified gearboxes and never in those that used the former oil -API GL4 SAE 75W90- according to standard TL 521 57 (synthetic oil) |
| t
| Oils with different denominations and standards should never be mixed as this modifies the properties of the lubricants |
