Determining The Correct Length PTO Shaft
To determine the correct length of the driveline, it is
advisable to hook the machine to the tractor and place
the machine in order for it be at a minimum distance
between the power takeoffs.
Install the two uncoupled and unprotected semi-shafts
to their respective PTOs.
At this point, verify any interference of the outer tube
with the yoke inner tube and establish how much the
outer tube needs to be shortened.
Towed Machines
In towed machines, the minimum distance Dmin
between the joints occurs during steering.
Verify that, in the condition of maximum extension,
which generally occurs when the machine is aligned,
the coupling between the two tubes is sufficient.
When determining the minimum and maximum lengths
and during subsequent verifications, it is important to
bear in mind that ground subsidence may cause further
reduction and increase of the distance between the PTOs.
Bondioli & Pavesi does not recommend modifications to its products. If the
driveline needs to be shortened, proceed as described below. If you are
unsure of the procedure, or need additional assistance, please contact your
local implement dealer or qualified service centre.
1. Remove shielding.
2. Shorten drive tubes by required length. In
normal conditions, telescoping tubes must
always overlap by at least a ½ of their length.
During manoeuvres, when the driveline is not
rotating, the telescopic tubes must have a
suitable overlap to maintain the tubes aligned
and allow them to slide properly
If the driveline is fitted with a single chain
restraint system (splined inner tube), the
tubes can be shortened by a limited amount
(normally no more than 70mm) to avoid
eliminating the splined ring connecting the
two shield tubes.
If the driveline is fitted with a greasing system
incorporated in the inner drive tubes, the
tubes can be shortened by a limited amount
to avoid damage to the lubrication system.
Carefully measure and shorten each drive
tube equally.
