Transmission/ Clutch

I have a Farmall 504 5 speed with no TA. When I go to shift it into a different gear even if I throttle it all the way down it likes to grind when going into gears. It?s like it is not slowing something down to synchronize. Is there a adjustment I can do to the clutch or something. Thank you.
 
Normal.It's gonna to just do that. They're not made to shift 'on the fly' like a car. come to a compete stop to shift.
 
There are no synchronizers in these transmissions. You,the operator are the synchronizer ! It takes practice to shift while moving-it is better to come to a complete stop to shift.Mark
 
When shifting gear on a tractor you have to push the clutch down and wait a few seconds for the input shaft to stop spinning. If you need to change to a higher or lower gear you push the clutch down come to a complete stop then shift. Most tractor have straight cut gears and not made to be shifted in the fly and down so can/will cause gear damage over time
 
If your clutch is not adjusted properly it can add to the grinding. The clutch pedal should move about 1 to 1 1/2" while pushing it before you feel the resistance of the throw out bearing contacting the pressure plate fingers to begin releasing the clutch. Anymore free play than that might cause it to not release properly. To check for proper release with the engine running put the trans in any gear. Then take it out of gear into neutral a few seconds, continuing to hold the clutch completely down. Then put it back in a gear. If it grinds when you put it back in gear the clutch is not releasing properly.
 
The correct spec for clutch pedal free play is in the owner's manual and any service manual. The free play measurements provided here are for tractors with nearly straight vertical clutch pedals, measured level with the top of the platform, straight horizontally to the clutch pedal.

I know the measurement was different for the 656, and the 504 has a similar clutch pedal setup where it bends back underneath the platform.

Here is a thread I found on someone having a similar symptoms, but the problem was totally off-the-wall:

In that case it could be low on transmission oil or the oil is to thin or the clutch is out of adjustment
 
IF you Hold the pedal down start th tractor and it grinds going into gear, the clutch driven disk is dragging on the face of the flywheel or Pressure plate. Or the pilot bearing is dry and dragging. If the disk it could be warped and touching. The splines on the clutch shaft could be worn from a previous clutch and hanging the current one against the fly wheel. The pilot bearing is not externally lubed (IIRC) jim
 
I thought the M was one that had a grease fitting, requires turning the engine to a specific position to expose the fitting. Either way, the Owner's Manual covers it.
 
Jim's method is also good. And his other points are also spot on. All that without flaming the OP'er about his gear grinding. As far as shifting an old Farmall on the fly ya it may be a little abusive to the gears... but. When I was a kid back on the farm in KS we had a 300 & 350 with TAs, both were used on our 47 wire tie baler. Those tractors both got a lot of shifting on the fly. If you learn how it's not all that hard on the gears. I guess we preferred productivity over perfect gear teeth. lol
