The 1045 used engine drive pulley 5412 on K241S-46219a engine. (multi-groove)
The 1055 used engine drive pulley 5412 on K241S-46219a engine. (multi-groove)
The 1075 used engine drive pulley 6122 on K241S-46219a engine. (multi-groove)
The 1046 used engine drive pulley 6936 on K241S-46219a engine. (single groove)
The 1056 used engine drive pulley 6483 on K241AS-46333d engine. (single groove)
The 1046 came with the PT-6 pto as standard equipment.
It has been said the 1046 was built to use up an excess of parts inventory and they appear to have been built at the end of the 1966 production run as no 1966 tractor serial numbers have shown up after them.
The PT-5 pto clutch plate is keyed to the crankshaft and assume it was released in 1965 for 1-1/8" shaft.
The PT-6 pto clutch is bolted to the engine pulley and assume it was released in 1966 for 1-1/8" shaft.
The PT-7 pto clutch is bolted to the engine pulley and assume it was released in 1967. In the manual is states this clutch requires 2-1/2" engine pulley 7363 for all 8hp and 1046 tractors with gear transmissions. The PT-7 appears to be for engines with 1" crankshaft.
The drive belt and belt guard are the same for the 1046 and 1056.
What is the difference in the 6483 and 6936 drive pulleys? Is it the bore?
Does the 10hp K241S-46219a engine have a 1" crank on the 1045, 1055, 1075 and 1046?
