First take off the back motor guard (two small screws). Second the four small nuts 11/32" must be removed and the motor bracket #4 removed their is the back bearing of the armature in the bracket it may be stuck just move it side to side until it loosens up if you have a white "v" start switch disconnect it from the capacitor you may have to take out the knife bearing unit that in-tails removing the blade and removing the four screws underneath the blade pull the bearing unit out. While you have the knife bearing unit out see how much oil is in the cavity if there's oil touching the bottom of the gear when you pull out the armature you may want to put some paper towels in the whole were the armature comes out because this Oil is not friendly very thick and hard to clean up. Also on the armature if you have a hard time pulling it out put two screwdrivers on opposite sides of the back bearing and give the screwdriver a little nudge it should come right have the towels read now for the hard part. You have four post sticking out they have four screws holding a retainer for the stator, you need to remove the screws and take the clips out. The stator may come out now just reach in to the back of the stator and see if it comes out that is if it was a perfect world. Page two on the removal is to put some heat on the four columns that the stator rest on usually at 3,6,9,and 12 o'clock and add a little liquid wrench type material. now again if that does not work let me know and I will try and go one more step. I hope this help.
This takes some patience! But you need to un-loosen the two 9/16" bolts holding the gauge plate now slide it close to the blade keeping it around a 1/16" from the blade. Now tighten up both of the bolts do not over tighten one without the other being fairly tight you will see what happens when the bolts get up th the last turn. If you can not get the gauge plate even with the blade you may have to use a shim under the carriage this may be were patience will help. When you think you have it figured out it gets out of line more then before. Just do it in reverse of what you think will work
The indexing knob being tight will take a little work. First of all you will need to dismantle the indexing assy. I would start by sliding the top rail away from the indexing plate and spring, now try and remove the 9/16" nut on top of the plate after that is done slide the plate away from the indexing worm gear. Now you will have to remove the stud (Number 29 ) that is in the gauge plate support rod. Now the fun will begin if you have a small torch place it on the protruding cylinders that the gauge plate support rods go up and down on and get a rubber mallet and start to get the whole gauge plate (number 1 ) to come out after you complete that feat start to clean up the rods and the cylinders that they go up and down in. Do not use a file just cleaning solution and steel wool if possible. Make sure the rods will slide up and down freely before putting it all back together if you have some white lithium grease that is a big help. Now stop using veg oil or any kind of oil except mineral oil on the rods along with the slide rods.
Take the slicer turn it over take off the carriage first now you either have either four bolts holding on the two slide bars or the slide bars have to come out the back of the slicer if that is the case you will have a retainer clip next to the back of the slicer fitting into the slide bar push them up with a screwdriver now let's get the slide bars You are going to have to take the carriage tray holder off that is held on with a 3/4" bolt now if you have the style with the four bolts disregard this part try moving your bars back and forth if you can put a little heat on the area by the back of the slicer where the slide bars slid out and find a way to get the bars out when you have the bars moving. You will need to free up the carriage slide assy a little heat helps if you have Blaster or any kind of penetrating oils use them liberally clean off the bars real real good take a brush to the bushing inside the carriage slide clean them up good now be careful that you do not lose the two slide bushing on the top of the carriage slide that runs along the top slide bar.
