DRIVE-LINE FITTING ADJUSTMENTS
PTO drive-line data on model 4 and 6 tool barn PTO driven chippers and chipper mulchers with speed –up kit
options.
This data is for drive-line fitting adjustment, which is required prior to initial startup and installation of
chippers.
Prior to startup, the PTO that is supplied with your chipper must be properly sized to insure proper operation.
If this is not done, damage to the chipper, PTO, and tractor PTO drive-line will occur.
These calculations are vased on the following assumptions:
1.
The PTO drive-line used is the one supplied with your chipper with a size 2 PTO shaft spline for a type 1
spline on this tractor PTO.
2.
The drive-line has an active length range of 24.5” to 21.5” and that 2-1/4” of contact area on the tractor
PTO spline and 1-3/8” of contact area on the chipper spline shaft are utilized.
3.
The two shaft ends are horizontal with one ancther.
The following steps should be taken to insure the proper fitting of the PTO drive-line (provided with your
chipper) with your tractor PTO drive.
1.
Attach the chipper to your tractor three-point connections.
2.
Raise the chipper to a position where its drive-shaft is level with the tractor PTO drive-shaft. this
horizontal position is recommended for operation of the chipper.
3.
A maximum of 15 degrees of offset from the horizontal position between the two shaft ends is allowable
for proper operation of the unit by the PTO drive-line manufacturer. However, drive-line calculations are
based on a level, horizontal position.
With the two drive shafts level with one another, measure the distance between the ends of the two
shafts. ( the chipper and the tractor PTO shaft ends ).
This ditance between the two shaft ends is the measured shaft end distance, or “msed”.
The PTO drive-line is capable of handling a msed between 18.76” to 21.76”, allowing for at least 1/3 of
shaft overlap as recommended by the drive-line manufacturer.
4.
If the msed is longer than 21.76” a longer drive-line is needed and should be ordered.
5.
If the msed is shorter than 18.76” a shorter drive-line is needed and shour be ordered.
6.
Most drive-lines must be adjusted to fit by cutting off equal amounts of the ends of the shaft tube and
the guard tube of the PTO diver-line.
7.
Consult the drive-line manufacture data enclosed with your drive-line for proper assembly, disassembly.
Lubrication and operation- prior to startup, and during operation.
REMEMBER:
Contact with the drive-line wile in use can result in serious in inuury or death.
Any portion of the drive-line not shielded must be guarded by an interactive guarding system.
The manufacturer of the equipment is responsible for providing guards. Any replacement is guard must be
one which is specified by that manufacturer. in short, do not remove any of the plastic safety covers on the
drive-line, and insure that caution is used around this drive-line no one should be in the drive-line area when
it is operating.
Another dive-line data base is as follows – these calculations are based on the following assumptions:
1.
the PTO drive-line is the bondioli model 7102043nnt07607 with a size 2 PTO shaft spline for A type 1
spline on the tractor PTO.
2.
The drive-line has an active length range of 31.06 to 25.13”
