New PTO Belly Mower Pulley Insert with Mounting Bolts for International or IH Farmall Cub and Cub LoBoy Tractors.
Please note that International and IH Farmall Cub tractors have an unique PTO setup.
The Cub PTO shaft is a 15/16" with 10 splines and rotates counter-clockwise at engine rpm. This is unlike the common standard 540 RPM tractor PTO that rotates clockwise and has a shaft diameter of 1-3/8" and has 6 splines.
Please note, this is a TAPERED INSERT for use with the new style tapered pulley / belt sheave.
The NEW style tapered insert measures:
2-1/2" inch at the top of the flange.
1-5/8" inch at top of tapered insert
1-9/16" inch at bottom of tapered insert. Length of tapered insert which goes inside pulley is 1-1/32" inch.
This tapered style insert is held in place by the two bolts, as shown.
The original old style pulley used a straight bore insert which has a keyway and is held in place by 3 bolts.
A original style straight bore insert is shown in the last image for reference.
If you need an original style insert please contact us for availability.
