  1. Like others indicated the main clutch operating shaft has the release bearing fork attached with two thick washers in shaft slots and bolts that go through washers that clamp fork to shaft. If bolts and washers are in correct the only way shaft can move over is a ear off fork, failure of another part or someone didn't have parts in place. If main clutch releases without problem, it would be a long shot that the fork could be clamped tight enough out of center without washers in key slots to hold up over time without slipping on shaft. Take flat plate off under clutch and try to see problem. T/A release shaft has two keys and a set screw for fork plus the rings on shaft to keep it centered.
  2. Check the throttle linkage for moving arm on back of governor so arm under side cover see if the lower 1/4 adjusting bolt with lock nut is contacting the housing. If it is, more RPM will happen by backing the stop bolt out unless already backed full out. If spring is to weak to overcome the weights a stiffer spring can raise RPM. Look at a hardware store that has a selection of springs to find a stiffer one the same length or a shorter one the same tension. Those springs are cheap enough that you can bend and change lengths if needed. All linkages inside and out need rechecked after changes.
  3. Using a D-281 crank in the D-264 may run into problem of getting a regular rear main seal. 281 used a different seal and seal retainers. 281 seal retainers would work but the seal maybe impossible to find. If 264 seal is used with 264 retainers the 281 crank doesn't have oil groves to divert oil away from seal. Can find a 281 type seal in a 264 because IH sold a kit to update the engines. Supposed to dull sharp edges on the oil diverter groves when used. But IH dropped replacement seals and no one else has any last I checked. late D-264 in 400 tractors also used the 281 seal and crank. Some that post on RP Indicate using the rope seal on a 281 crank will work. Never tried myself. Some info lists .002 to .003 out of round before turning is acceptable and another later manual lists .002 to .004.
  4. SMTA tractors of all types used a different design rear housing than plain supers. PTO opening was bigger and sealed with a o ring instead of a gasket. PTO pictured is the independent planetary PTO for a SMTA and others. SMTA tractors could be had with a transmission driven PTO. Off rear of counter shaft if no T/A, or off clutch shaft with gear on it to drive a lower gear and shafts to PTO with a T/A.
  5. Could be not rich enough. How far is the adjustment screw that points to front of tractor screwed out? Try opening it up some or try with choke on some and see if it temporary helps.
  6. Think all equipped with a reverser had provision for IPTO. Only seen those with a clutch type PTO but can't say some didn't have a planetary PTO. Not common with reverser and not a lot of 340 around.
  7. Looks to have the hollow counter shaft to drive like IPTO. Only hitch is a outside chance if it still has what they called a transmission drive PTO equipped with a T/A, they had to drive it ahead of the T/A because it changed countershaft speed. Way to see if its IPTO drive is being carful have someone hold brakes and put transmission in a forward gear so friction doesn't turn the PTO shaft. Be sure they keep clutch disengaged. Have them hit starter to spin engine, unhook coil wire to keep from starting. Watching through PTO mount hole for shaft spin, if so all you need is the correct PTO unit and extension shaft. Make sure it doesn't have a serial plate. Lot of people look on the wrong side. Located on right side or brake pedal side on clutch housing. If found the serial number and suffix letters would answer questions. If you don't have any number the rectangular plate near front of housing can be removed and count gear teeth. Oil needs drained from plug in plate though. Top plate on center housing can also be removed and count teeth on upper PTO drive gear, but probably more work. Only difference in transmission drive with a T/A and IPTO drive is IPTO used a shaft with gear driven from pressure plate. Transmission drive used a shaft with gear driven from clutch plate. Upper and lower drive gears had different number of teeth for both types.
  8. Some belt pulley gear boxes can be removed by leaving the long bolts in housing after they are loose.
  9. One difference in a disc brake tractor and a band brake one is the M&W clutch cover bolts direct to the transmission housing on a band brake M like the brake cover. On a late M or SM a adapter plate is bolted onto the differential carrier retaining bolts with different bolts to mount the M&W clutch or brake cover. Adapter plate also retains the bull pinion bearing and bull pinion. Worked with both before but memory is fading. Pretty sure though the M&W shaft that goes in the differential gear and out to clutch is longer than a band brake M one. Also a few other differences. Unless owner modified all the M&W clutches I messed with had a straight shift lever with knob above the leather hole cover. But bent ones may be around. One thing helpful on a disc brake tractor is the unit can be installed or removed without going inside transmission housing to move or remove a bull gear like a band brake tractor. Dave
  10. If for a D-264 4 inch bore the IH piston number would be 264320R1 or higher suffix number. Or if going to thin wall sleeves the piston number is 277071R1. One sleeve assembly 264338R96 for 4 1nch bore. 277077R91 for 4.125 bore. Sleeve, pistons, pin and rings. Hard to find.
  11. Without double checking I would say that is for a SM gas. IH pistons for a D-264 and D-281 start with the number 2. May have guessed wrong, could be a 5000 altitude for a C-248.
  12. Way things are going the diesel may get to😃 be like buying HY Tran.
  13. Would need my memory refreshed but circled on mounting surface should be open to hole behind the venturi. But think it's not the hole you have circled. Whatever hole it comes out a small wire should go through to opening behind the venturi. Hole nest to that one goes to idle mixture screw passage and small hole near butterfly closing. Could look at one tomorrow to be sure.
  14. Think May June RPM arrived in first week in May. Regular mail.
