While I was cleaning the transmission for my Simplicity 728 restoration , I realized that there are two adjustment screws on it. I probably have changed the settings on them and have no idea how to readjust them.simp 728 trans close up.jpeg

See the slotted screws with locknuts in the picture.Guess I'll have to try and find the service manual that applies. I hope I haven't messed up something that I can't fix.

Can you zoom out so we can get a better idea of what the entire part looks like?  Not sure where you are on the transmission.

simp 728 trans cleaned.jpeg

The two screws/locknuts are near the bottom in this pic. Bottom center is actually the front of the gearbox, where the shifter is. I removed the locknuts to remove the metal plates from the side of the gearbox. Not until after I had cleaned the trans did I realize that they were adjustment screws. During all the scrubbing and cleaning they very well could have been screwed in or out some. I don't understand what they adjust. Thanks.

I have looked at parts breakdowns of the trans and cannot find the screws shown in the parts diagram.Here are some better pics.

The two screws are hidden behind the large belt drive pulley. The nuts have to be off to remove the side plate. The plastic plug shown in the third pic is right above the screws so maybe I can remove it and see what the screws do. They do not turn freely, so maybe I haven't turned them. I don't know.

Just a stab in the dark, but they could be for the "Shaft, Hi-Lo" (71) and "Shaft, Shift, Reverse-Lo" (76).  If they are, you may want to read the note on page 26 of the attached PDF.

Thanks. The note says to never loosen the two screws unless you intend to completely disassemble (and reassemble) the transmission. I hadn't planned on doing that. I'm thinking lock the screws back down and hope for the best. What would you guys and or gals do?

I cut out shortly thereafter, staring at the diagram trying to figure out why the adjuster screws are there fried my brain.
