PTO HYDRAULIC PUMP DRIVE
Our PTO hydraulic pump drive has been developed for use as a directly driven hydraulic pump speed increasers. The drives are designed and manufactured in Australia. Customers can obians parts directly from the factory. Our Engineering staff can provide asstance to equipment designers.
CAST IRON CASES – Unlike our competitors, we utilise cast iron gear case construction. Cast iron expansion at the high temperatures encountered with this application is near equal to the expansion of the bearings and the outer bearing rings are retained in the case. Aluminium cases with high heat expansion often fail due to the outer bearing ring spinning and displacing particles of aluminium which destroy the bearings.
PARTS AVAILABILITY The drives have been designed in Australia and are manufactured at our facility in Ballina N.S.W. Customers can obtain parts and service without delay. Technical assistance is available from the people who designed the product.
Tractor PTO Hydraulic Pump Drive
MODEL T33 APPLICATION These models embody over 20 years of engineering experience with PTO pump drives. They were developed for use as directly driven hydraulic pump speed increasers for 540 or 1000 RPM tractor PTO shafts. Models for 540 RPM PTO’s are provided with a 1 3/8” 6T spline hollow shaft and for 1000 RPM PTO’s, a 1 3/8” 21T spline hollow shaft. Shafts are splined internally for full length for through drive. Normal practice is to utilise a torque arm to restrain the drive from rotation.
Maximum power is 50 HP (37.5 kW) with the 1:3.31 ratio models at 540 RPM input and 65 HP (49 kW) in the 2.04 ratio models at 1000 RPM input. The T33 is available to accept most SAE “A”, SAE “B” or SAE “C” hydraulic pumps. Pump adaptors on the T33 may be changed in the field. DIN 2 & 3 adaptors can be made to order, please consult with our Sales Office.

MODEL T33I APPLICATION This model was developed for use as an implement mounted hydraulic pump speed increaser for 1000 or 540 rpm tractor PTOs where thrust loads from PTO shafts are encountered. Tapped mounting holes are provided.
Maximum power is 50 HP (37.5 kW) with the 1:3.31 ratio models at 540 RPM input and 65 HP (49 kW) with the 1:2.04 ratio models at 1000 rpm input. The T33I male shaft input model is available to accept most SAE “A”, SAE “B” or SAE “C” hydraulic pumps. Pump adaptors on the T33I may be changed in the field. DIN 2 & 3 adaptors can be made to order, please consult with our Sales Office.
The T33I male shaft input & output model is supplied with a Ø1 1/2” x 3/8” keyed output shaft.
