IBM Selectric II keeps returning to right.

If you can hear the motor running but nothing at all works the motor belt is probably broken. Not a job for the untrained.

Under the R. black plastic dust cover there is group of cams and arms spray the two sets of arms and the cams with WD40 this shouls free up the arms.

Sticky latch on right side. Requires cleaning and lubrication

There is a thin metal ribbon in the back that has come off the wheel. It is a devel of a thing to get back on.

Remove the cover and watch ... you will see what I am talking about.

It may have come un-attached ... equally difficult to fix without the little thingie the typewirter mechanic uses.

good luck

Sounds like the return lever arm is not putting enough pressure on the return clutch, or the clutch is slipping. The exp key uses the same clutch but the pressure comes from your finger. Theres no way you can fix this yourself. Get an IBM mechanic.

space to the right side of the machine, hold down the tab clear key and hit return.

If the carriage stops partway back, one of the tab stops has rotated too far on the tab bar.

remove the platen and paper pan, go to the stuck stop, rotate it to the rear of the machine to line up with the other tabs

If you know how to remove the right dust cover (black inside the T/W below the carrier) next to the R. side frame is the correction set up mech. spray some WD40 on the arms especially where they pivot, they should free up.

Is the key stuck in the down position? If you pull the key off you should see a spring underneath. Maybe out of position or damaged.

Sounds like you have a broken torquo limiter tension spring you should have it professionly serviced.

The return clutch torque limiter is off or broken. If you take the right dust cover off it is on the turning hub around the middle of the typewriter. a small spring about 1.25 inches long with a hook on the end. I have been fixing these for 35 years. good luck. Lawrence
