GEARBOX LUBRICATION (V-25APC WITH A503 GEARBOX)
The Bonfiglioli A503 gearbox used on the V-25APC is supplied with 11 liters (2.90 US gallons) of Mobil SHC 634 synthetic
oil. This oil has an ISO Viscosity Grade of 220 that is optimum for ambient temperatures from 20 – 40 Deg C [70 – 104
Deg F]. If the machine will be operated for prolonged periods at ambient temperatures below 20 Deg C [70 Deg F] an oil
of ISO Viscosity Grade 150 should be substituted. If the type of oil is being changed, it is advisable to flush the old oil by
filling the box with the normal quantity of the new oil, running it briefly at moderate speed, and then draining the box again,
before re-filling it with a fresh quantity of the new oil.
Because of the tilted orientation of the gearbox on the V-25APC, the correct oil level is to the bottom of the fill plug “A”
shown in the photo. The gearbox can also be filled at the breather shown in the photo.
The suggested oil change interval is given below:
Oil Temperature
Deg C [deg F]
Mineral Oil Interval
[hours]
Synthetic Oil Interval
[hours]
< 65 [< 150 ] 8000 25000
65 – 80 [150 – 175 ] 4000 15000
80 – 95 [175 – 200 ] 2000 12500
OUTPUT SHAFT LUBRICATION
Band tension load is carried by a grease lubricated spherical bearing. A grease fitting is
accessible on the back side of the drive box as shown in the accompanying illustration.
Lubricate once per year with 30 ml [1 fluid once] of NLGI Class 2 Lithium base mineral oil
grease. This quantity represents about 20 to 30 strokes of a typical hand grease gun.
