• Lock the tool's support plate in a vice and insert the lay shaft bringing the flange's ridges in line with the ring nut's grooves. To keep the shaft in this position, use the screws supplied with the tool and tightened on the bushing (29). • Apply the tool AV 3247 to the end of the shaft and unscrew the bearings' retaining ring nut. • Adequately support the internal race of the front tapered roller bearing (25) and, using the press, detach the assembly composed of the two tapered roller bearings (25 and 27) from the lay shaft, from the intermediate spacer (26) and from the bushing (29).
Component maintenance and overhaul In order to carry out a visual check of the components, it is advisable to thoroughly wash all the metallic parts using a solvent, biodegradable if possible, and blow them with compressed air. Pay particular attention to the internal lubrication channels, on the gearbox shafts, housing and covers, which must be spotlessly clean. Check that the housing and the covers show no indentations and that the bearing seats are intact, without scoring or ridging. If this is the case, they must be replaced immediately. Check that the surfaces and the edges of the gear toothing show no signs of wear or spalling. The contact area must extend over the whole surface of the toothing and must look smooth and uniform. Replace all gears showing signs of said defects. Before reassembling the double gears (31 and 32), it is necessary to visually check the coupling surfaces: they must show no signs of scoring or buckling. Check that the gears have maintained the minimum specified interference with the lay shaft ( D 1.01). If this is not the case, replace the components immediately. Check the sides of the sliding sleeve for signs of wear, along with the contact surfaces of the gear shift forks. It is extremely important that the contact surfaces of the fork and the sleeve remain upright in respect of the support rods. Check that the shimming surfaces of the idle gears, the spacers and the shoulder rings show no signs of snagging or seizure. Replace if this is the case. Check that the engaging teeth of the sleeves and of the idle gears show no signs of snagging, spalling or excessive wear, which would impede engagement. Check the threading and the grooving on the shafts and the synchronised elements on the reverse driving gear are in good condition. Plugs for tapping the machined holes are fitted on the gearbox housing along with tapered thread plugs (56, 57 and 58) which close the lubrication ducts. When disassembling, apply LOCTITE 510 on the threading. The oil bleeding neck (59) is fitted flush on the housing. Check that it is not clogged with foreign
