A quick guide to identify the best cardanic shaft for your needs Please follow in order these steps: 1) Identify the maximum couple to be transmitted (Mt), including the security coefficient (table 1) 2) Working length (minimum working length + needed extension/2) 3) Chose the right flanges (a different one for each side of the shaft, if necessary) (table 2) 4) Verify feasibility and conformity with respect to max etc. and define maximum couple and speed Example: AC 767 N / Lm = 830 / M-P Max couple 700Nm Max speed 1500rev/min The above data identify the following needs: Cardanic shaft series 767N, working at 855mm (from 830mm to 880mm); Flange SAE 1310 on the shaft shifting side and flange DIN 120 on the shaft fix side.

Our technician will verify if the installation is correct, asking you more technical details if it is necessary
On request we can manufacture cardan shafts with different characteristics then those appearing on our standard catalogue
Handling
Incorrect handling of the drive shaft may result in serious damage and affect its operation. It is essential to follow these rules: Always handle the drive shaft horizontally Do not knock or roll the drive shaft Ensure that the sliding part of the drive shaft WS does not come out Hold the drive shaft only by the inside yoke and never by the universal joint
Assembly
Do not alter in any way the drive shaft and its components. Mantain the condition in wich it has been supplied Before installation, ensure that all lubrificants, paint and general dirt has been removed Make sure the marking arrows on the shaft are alligned Make sure that the fastening holes are perfectly round and not oval Connect the driving shaft to the attachment on the counterflange of the engine. Fix it initially with two diametrically opposite bolts. The same operation must be done on the counterflange of the driven axle. Make sure it is centered exactly and that the counterflanges support each other. Finally complete the attachment During assembly do not insert levers or other tools into the joints and do not hammer the flanges We recommend to use non lubrificated fastening bolts, according to the quality requirements: The exagon head cup screws partially threaded according to din 931/10.9 The self blocking nut according to din 980/10 The standards nuts must be tightened with a torque spanner according to the values stated and it should be periodically checked
Lubrication
Drive shafts are not lubrificated, before the assembly apply grease to the knobs. The recommended grease should have a melting point of - 20° + 140°(es. Esso multipurpose, Grease H, Fiat Jl, Caltex, ..etc) The maximum lubrification pressure should be 15 bar. Apply the grease into the universal joint until it comes out from the universal joint sealing. The intervals between lubrification are shown in the table below. Different conditions may require more frequent lubrification.

Maintenance
If the drive shaft makes a noise while in use, the vehicle or plant must be brought to an immediate standstill. If repairs are needed, these should only be carried out by a specialised workshop who have suitable material and equipment. In other cases you must contact the head office. Check the clearence on the universal joint and on the sliding parts every 500 hours. If the clearence is in excess, the drive shaft needs to be disassembled and repaired. The lifespan of the dirve shaft depends on correct use and adherence to the regulations set out by head office.
Safety instructions
Ensure the main switch is off bifore start working on the drive shaft Do not exceed maximum rpm speed The drive shaft must be used in condition wich guarantee safety for people and surrounding areas equipment etc,... rive shafts are considered "security components" (directive Cee 85/374) and consequently must be in accordance with the specific laws Incorrect use of drive shafts may cause serious damage to people and machines in contact with them.
