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?

Trying to match up the pto manuals to the tractors they were used on and ran into a conflict. Searching the archives I see I have tried this before. Can anyone help?

 

It appears the problem according to PSB #338b is the pto and engine used.

The 241S-462198 may be a typo for 241S-46219a which I believe uses a 1" crankshaft.

The PT-6 is for a 1-1/8" crankshaft and listed as standard equipment on the 1046.

      1966 1046 crankshaft diameter
      By gwest_ca-(File Mod)
      What is the crankshaft diameter on the K241S-46219a used in the model 1046?
      Just posted what I can find for this model and the PT-6 pto listed in the service bulletin does not look correct to me. PT-7 is the 1" pto.
      Don't want to post incorrect info.

      1046
      By Rooster
      I have been doing a little searching for info on a 1046. I picked up one in a lot I purchased recently and have been told it was a low production model.
      Did not find any pics so I figured I would ad a couple to the gallery.


      SO how many of you have one of these? Are they as rare as some have led me to believe?
      I am not going to restore this one, actually I am going to use it.
      Hopefully some day it will go to another member who will appreciate it more than I. Not that I do not love the tractor, but I am not a collector and there for low production Numbers and "Rare" to me mean nothing more than I should be careful about what modifications I make, etc.. If this is indeed a "rare" find, it needs to be in the hands of a collector.

      What is a fair price for a 1045?
      By formulaross
      Have a running 1045 to sell, with mower deck and snowblower. 10 Hp Kohler engine. Bought new, one owner, belongs to my in-laws. Location: Indianapolis. What would be a fair price?

      Here Goes the 1056
      By Texas Todd
      Well, everyone inspired me to give a resto a shot.  Bought this 1056 that the seller said had a factory re-powered 12hp K301S.  Guess not having the generator isn't a bad thing, but what do I know?
      Wheel Horse tires must be original. Not bad to get 50 years out of a set of tires.
       
      Drained the trans-axle and it looked like and was the consistency of pancake batter. Thick pancake batter.  The wiring was done by someone, who, well, someone whose daddy didn't teach him right.  
      Lots of bailing wire to be replaced with proper hardware......42" deck has some cancer but seems to operate okay.
       
      I'm sure I will have a lot of questions in the coming months. Sure hope for a before after picture down the road like I see on here all the time.

      1056 Mower deck belt
      By deere173
      I have another belt question, this time on a 1056 tractor with mower deck. I received the tractor with the deck belt tensioning idler bracket resting against the underside of the right-hand steering tie rod. There is no spring, just the belt itself applying tension forcing the bracket against the bottom of the tie rod.  The tie rod is badly worn from the machine being used like this for years.  In the photo, it's the bracket angled downward resting on the floor. Anyone know how this is supposed to be positioned? Are there parts missing ?
