powermax double pulley question - pics

Recommended Posts

hi - another question came up in the process of replacing my onan - when i went to put the double pulley onto the flywheel adapter on the new honda something was wrong - the bolts wouldnt go in - so i removed it to find the bolts tha fit my pulley and were on the onan flywheel are 7/16" while the holes on the new flywheel adapter are 3/8" - this was a major problem and stopped the project for awhile - i wondered if i had gotten the wrong adapter some how - if i was to use the pulley with the 7/16 holes i would need to put some sort of reducer in the holes to bring them down to 3/8 so there would be no slop or movement in the bolts - seeing how much it will be torqued back and forth it must fit exactly - well i had an extra pulley in the house so i went to compare them - well they had two different size holes - 7/16 and 3/8 - so i grabbed the 3/8 and the project was back on track - did different models use different size bolts ? - did maybe the models with pto's have bigger bolts to support the extra torque ? - or was my pulley modified ? - it looks original - the manual i looked at shows 3/8 " bolts - did ccka flywheel have different bolts than cckb flywheel - one cckb flywheel i have has 3/8 bolt holes and the other 7/16 - what size bolts do others have ? - im interested because this could be a potential problem for others changing motors - thanks [img]http://www.simpletractors.com/club2//attach/schaefer72/honda%20pics%20019.jpg[/img]

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
