PTO SPEED REDUCER
The AL00630 gearbox is a designed to alter the output speed of your tractors PTO shaft. Its versatile design allows the gearbox to be used as either an increasing ratio or decreasing ratio gearbox to suit your needs.
As a decreasing ratio gearbox it will reduce 1000 rpm PTO shaft speed to 540 rpm allowing the use of equipment designed to operate at 540 rpm.
As an increasing ratio gearbox it will increase 540 rpm PTO shaft speed to 1000 rpm.
The AL00630 gearbox is assembled with 2 x internal splined sleeves. One 13/8″Z6 the other 13/4″Z20. These splined sleeves allow for direct coupling to your tractors PTO shaft as the input. The gearbox is also supplied with 2 x separate shafts with matching splines. These are easily assembled to give you the required output shaft.
Notes:
– Although designed for attachment to a tractors PTO shaft this gearbox can be used in other applications on agricultural machinery.
– A lug is supplied fitted to the base of the gearbox housing. This must be securely attached to your tractor by way of a chain or mounting plate to ensure the gearbox does not rotate during operation.

NOTE: When fitting splined shafts
Take care when tightening the 4 x locking bolts inside the housing. These bolts fix the removable splined shafts in place.
1) Tighten bolts to avoid oil leaking during operation. (The bolts have a seal under their heads.)
2) Loosen the bolts only when fitting the shafts. DO NOT remove the bolts completely. If removed they may drop into the housing and cause a failure. The box must be disassembled to retrieve the bolts if this happens.
