Will do! And as soon as the infeed roller is back in stock, I will order both and report back after I get them and compare them to what's in the machine.Originally Posted by Ken Fitzgerald
No, sorry. I just started taking the thing apart and figured it out as I went. It kinda goes like this (proceed at your own risk):
1) Raise cutter head to top most position, and lock it into position with the cutter head locking lever. (to give you more room to remove the roller carrier bearing blocks). These are secured in place by small plates with two hex head screws.
Note: I have no better term to use than "bearing block". It's simply a square block that serves as a bearing at each end of the roller.
2) Remove top end bracket and center tray to gain access to the cutting head and roller gears and chains. (four hex head screws at the top of machine)
3) Remove the top cover of the gear box for raise/lowering rod (three small hex screws). The rod needs to be removed to gain access to the gear and chain sets. (just makes life easier).
4) Remove lock nut at the base of the raise/lowering rod. There is a flat on the rod, near the bottom to hold the rod with a wrench while loosening/tightening the lock nut. The rod should lift up and away from the machine now. It may need some slight twisting to "roll" the gear sets apart. (ensure cutter head locking lever is still engaged). I really do not know if the cutter head can tilt up/down, but I didn't want to test my luck.
5) Remove C-clips from gear/chain sets, and pull them off rollers. They slide right off. Take note of how the gear/chain cover is positioned. It will need to slide off and out with the gear sets.
By now, the rollers are ready to be removed. There is a spring that applies downward pressure at each end of the rollers. The spring is captured in a small pocket, between the roller end bearing blocks and the machine. I used a couple clamps to hold the rollers up, while removing bearing block retaining plates at each end (as well as when I re-installed them).
6) After the clamps are installed, securing rollers to the machine, remove the bearing block retaining plates at each end of roller. Two small hex screws hold each plate.
7) Carefully remove clamp and allow the roller to lower downward. Don't loose the springs. They will drop out of the machine.
8) Remove roller from machine. Remove bearing block and transfer to new roller. I suggest cleaning the block and wipe some grease on the new roller before sliding the block onto the rollers.
9) To hold the roller springs in position, in the machine itself, I used a good bit of grease. I slobbered some grease on the end of the spring, then kinda "stuck" it up in the spring pockets.
10) Slide the new roller into position, hold it there while you re-install your clamp onto the roller to raise it up into position against spring pressure. Don't force anything, just slight pressure. Once it is secured in the upward position, you can install the retaining plates.
11) After the plates are installed, turn/rotate the roller by hand. It should turn by hand (assuming you cleaned and applied new grease to the bearings), without a great deal of effort. It you can't rotate by hand, you've got something bound up. Remove, inspect, try again.
12) Reinstall roller gear sets and chains. Rotate rollers as needed to get the key ways to line up. Don't forget the chain cover when you do this.
13) Reinstall the raise/lowering rod. You might need to rocker the gear set back and forth with the raise/lower handwheel to get the rod's gear to mesh correctly. Just don't move it too much or the cutter head might get knocked out of alignment to the bed. Reinstall the gear box cover plate.
Install the remaining stuff......
