After some sliding (function of the use), the value of the transmitted torque decreases. Periodicaly check the
transmitted troque, and the state of the stack of discs.

Dismantling / reassembling
During maintenance work, ensure that the mechanism to be driven by the units is at rest and that there is
no risk of it being started accidentally. All intervention have to be made by qualified personnel, owning this
manual.
Dismantling:
•
Dismantle the driving part of the receving part
• Reduce the spring pressure (740), unscrewing the fixing screws (905), then remove the
pressure flange (362)
• Remove the cover (531), the bearing housing (533) and the bearing (803)
• Remove the worn disc set
• Fit a new disc set
Immerse the new stack of discs, in oil (see table 2), for about 12 hours.
• Inspect bearings (806) (803) and (801), replace if required
4.3 Important recommendations
The types of oil to be used for lubricating the discs should meet the following criteria:
• Good rust resistance
• No friction modifying additive
• No additive that might corrode the bronze friction surfaces (1a or 1b NF M 07-015)
• High viscosity index (>80)
The oils listed below (see table 2) meet these characteristics. The list is not exhaustive and other lines may be
added to it. The viscosity of the oil to be selected varies depending on the running temperature and speed.
4.4 Spare Parts
All orders for spare parts must state the size of the unit with its code number, the reference number of the
part (see appendice), and the quantity of each component wanted.
