Rotating shaft seals
T o correctly install rotating shaft observe the following instructions:
• Let the seal soak into the same oil will seal for least half hour before mounting.
• Thoroughly clean the shaft and ensure that the shaft working surface not
• Place the sealing lip towards the case a hydrodynamic consider the shaft rotation direction and orient grooves order that they deviate the fluid towards the inner side the
• Coat the sealing lip with a thin layer lubricant (oil rather than grease) and fill with grease the gap between the sealing lip and the dust lip double lip
• Insert the seal into its seat and press down using a flat tap the seal with a hammer a
• T ake care insert the seal perpendicularly its seat while you are pressing it. Once the seal settled, ensure that contacts the thrust element
• T o prevent damaging the sealing lip against the shaft, place a suitable protection during installation.
O - rings
Lubricate the O - rings before inserting them into their seats. This will prevent the O - rings from rolling over and twine during mounting which will jeopardise
Sealers
Apply one the following sealers: R SILMA RHODORSIL CAF 1 , L OCTITE ® P IASTIC G ASKET over the mating surfaces marked with
Before applying the sealer , prepare the surface follows:
• Remove possible scales using a metal
• Thoroughly degrease the surfaces using one the following cleaning agent: petrol a water and soda
Bearings
advisable heat the bearings - ( 176 - 194 ) before mounting them their shafts and cool them down before inserting them into their seats with external tapping.
Roll pins
When fitting straight roll pins, ensure that the pin notch oriented the direction the fort stress the pin. Coil roll pins can installed any
Notes for spare parts
Use exclusively genuine NEW HOLLAND spare parts.
Only genuine parts guarantee same quality , safety original components they are the same mounted production.
Only the NEW HOLLAND genuine spare parts can fer this
