Use a strong wire to pull them off from the front panel and avoid clamp deformations.
10. Remove the front panel.
A screwdriver can be used to loosen the front panel from the drum. Be careful to avoid any damage. Any damage will result in leaking.
11. Inspect the rubber sealing of the
front panel. If it is in good condition, verify it sticks on through its groove. If it is loose on some places, re-glue it using a SMALL quantity of silicone and let it dry. If the sealing rubber is NOT in good condition, remove the sealing from the front panel, clean the groove and adhere a new sealing #PRI504000031. Use silicone. When gluing the sealing, make sure it is not bent or warped and that it fits perfectly all around without sticking out. Respect the necessary drying time.
trunnion, using a standard 2-arm puller. Verify that the 2 hooks properly hook into the trunnion openings and catch the trunnion adequately. Before pushing, verify once more that the tolerance ring has been removed from drum shaft.
16. As soon as the main shaft
becomes loose from the bearings seats, remove the puller. Remove the center bolt and turn-in the extension rod #530112. Turn it hand tight against the top of the main shaft.
17. Carefully remove the drum.
Do this very carefully to avoid damage to the drum graphite sealing (if it doesn’t need to be replaced).
beams so that the drum opening does not get damaged. If the drum sealing doesn’t need to be replaced, go to step # 20.
19. Remove the Counter Face Ring
from the drum shaft (use a screw driver or a wrench to release it). Clean the seat of the drum shaft Counter Face Ring around its diameter. Do not alter the fitting dimensions. Remove all loose dust and dirt using a clean cloth.
20. Remove the seal holder from the
internal side of the tub. If the drum sealing doesn’t need to be replaced, go to step # 24.
Re-assembling the Counter Face Ring onto the drum shaft must follow certain steps. For this purpose use the Service Instructions 518345. Failing to do so, will jeopardize the function of the sealing and reduce the life time of the shaft.
damaging or deforming its shape. Carefully clean the seal holder seat to prepare it for new axial seal # PRI530020012.
22. Apply an even, thin layer of 3M
Scotch Clad 776 adhesive only on the lower external circumference of the axial seal. Use a small paint brush. Do not let it dry. Use tool # 51896 to push it immediately in the seal holder. Respect the necessary drying time.
23. Verify the seal sits against the
back wall of the seal holder. This is very important to ensure the assembly and functionality.
# 518892, the special axial bearing # 530129 and the special nut # 518882 on the threaded rod in the indicated sequence. Place a second rod # 514759 into the openings of the nut and push out the old back bearing. Then de-assemble the tool setup.
28. Install the special threaded bolt
# 530116 and cup # 530033. Use the auxiliary rod # 514759 for the special bolt head. Move the assembled threaded rod through the front bearing of the trunnion.
29. At the backside install the thorn
# 518894, the distance tube # 530036, the special axial bearing # 530129 and the special nut # 518882 on the threaded rod in the indicated sequence. Place a second rod # 514759 into the openings of the nut and push out the old front bearing Dismantle the tool set up.
substance from the bearing seat and its corners. Use “Scotch Brite” mat or a similar product that will not change the fitting dimensions. Remove the old bounding residues at the level of the seal holder. Then remove all loose dust and dirt with a clean cloth.
31. Use a clean dry cloth to wipe off all
grease, oil or dirt from the races of both new bearings.
32. Apply a thin film of Loctite 603
# 245704000603 (or similar bounding product) around the front bearing seat in the trunnion (not on the bearing!). Do not apply more than a thin film; otherwise it can jeopardize the function of the bearing.
# 518894, the front bearing cup # 518884 and the new front bearing on the threaded rod # 530116 in the indicated sequence. Use the auxiliary rod # 514759 for the special bolt head.
34. At the backside, install the cup
# 530033, the special axial bearing # 530129 and special nut # 518882 on the threaded rod in the indicated sequence. Place a second rod # 514759 into the openings of the nut and push-in the new front bearing. Apply continuous pressure until the bearing sits. Failure to do so will result in an improperly seated bearing.
35. At the backside, dismantle the
previous setup from the special threaded rod. Verify from the backside if the front bearing is fully sitting against the shoulder of the trunnion. Place a thin film of Loctite 603 #245704000603 (or similar bounding product) around the Back bearing seat in the trunnion (not on the bearing). Do not apply more than a thin film; otherwise it can jeopardize the function of the bearing.
Back Bearing on the cup # 518883, the special axial bearing # 530129 and the special nut # 518882 on the threaded rod in the indicated sequence. Place a second rod # 514759 into the openings of the nut and push in the new back bearing. Apply continuous pressure until the bearing is seated. Failure to do so will result in an improperly seated bearing. Dismantle the tool set up
37. Use the retaining ring pliers to re-
install the retaining ring at the front of the trunnion. Verify that the retaining ring fits into the groove over his full circle.
38. On the back side of the seal flange,
put a continuous bead of about 1mm of Loctite 5203 #100097 (or similar liquid bounding product) as indicated in the picture. Too much bounding will delay the drying process. Note: Mind the surface of the axial seal doesn’t get damaged or get dirty.
# 245704003021 (or a similar bounding product) on each of the stainless steel M6 bolts of the seal holder. Re-install the seal holder into the tub not forgetting the brass washers of the M6 bolts.
40. Slide the drum with the extension
rod # 530112 into the trunion until the bearing seats hit the inner races of the bearings. WARNING: Perform very precisely, so that the drum shaft doesn’t come in contact with the axial seal in the seal holder!
41. Remove the extension rod from the
main shaft. Place the Bearing support part # 530034, the special axial bearing # 514691 on the special bolt M20/M12 # 518912 with the M20 nut # 514690, as indicated in the picture. Verify that the flat front side of # 530034 is supporting both back bearing races and the bearing races ONLY. Failing to do so will damage the bearings.
special M20/M12 bolt into the threaded hole of the main drum shaft. Turn-in until it bottoms out. Pull the drum shaft into the trunnion with the use of the special wrench # 514695 until the rear drum shaft shoulder hits the inner race of the back bearing.
43. Clean the end of the drum shaft and
make it free of grease. Install the tolerance ring shaft and apply some grease, ONLY on the outside of the tolerance ring. Place the drum pulley over the shaft and push it on until it hits the tolerance ring taking care that the flat ends match each other. Note: if the tolerance ring is not in good condition, it is advised to replace it.
44. Place the Thorn # 518894, the
special axial bearing # 514691 on the special M20/M12 bolt # 518912 with the M20 nut # 514690, as indicated in the picture. Press the pulley onto the shaft until it hits the inner race of the back bearing. Dismantle the tool set up.
screw and Install it at the back of the pulley into the main shaft thread. Re-Install and verify the V-belts tension.
46. Re-install the drum front panel,
making sure that the marks correspond.
47. Use a strong wire to secure the
front panel by fitting the clamps crosswise until all the clamps are in position. If other tooling is used to put all the clamps in position, make sure the shape of the clamps is not been deformed.
rim, hammering it with a rubber hammer. One or 2 times if necessary. On this way, the front panel and the seal search their way against the tub rim around its complete circumference.
49. Re-install the counter weight.
Make sure the bolts also catch the shock absorbers as originally. Re-install the front panel and install the upper screws of the front panel. Connect and tie-wrap the connector (harness) of the door lock, so that it doesn’t rub and still has sufficient freedom.
50. Use the special extended screwdriver # 538779 to install the lower screws of the Front panel. Slide them from behind the front panel and tighten them. Then tighten the upper screws of the front panel. Re-install the door rubber sealing. Re-install and secure al panels in the original way.
