Service Midway motorized score reels
Steps
- Do not take the reels apart unless you must; the clutch stack is easy to reassemble wrongly.
- Tilt the backbox insert back to reach the four screws holding the reel set to its base plate, remove them and slide the set up and back off its slip joint.
- First just inspect: broken wires at the relay or bakelite plates, the latch relay's condition, and whether reels turn without binding with the latch on and off. Most faults are fixed here.
- If you must strip it (to clean the wipers and plates, fix clutch slip or a burnt motor), start at the end with the E clip: remove it and the two end plate screws.
- Remove each notched washer, spacer, reel and bakelite plate in order, noting and stacking them.
- Clean the wipers and plates with 400 or 600 grit and rebuild in exactly the same order.
