How to Adjust Rangefinder Leica M4?

Horizontal RF Adjustment
Adjusting the RF patch alignment at infinity is easy. You need a screwdriver that fits perfectly. When you make adjustments, only apply turning force. Don’t push against the rangefinder arm.
A screwdriver is used to adjust the focus of a camera lens. When adjusting the focus, the camera must be moved closer to or further away from the object being photographed. In this example, the screwdriver is used to move the camera closer to the moon.
A screw that holds the roller in place is called an eccentric. An eccentric pivot allows the user to adjust the relationship between arm movement (rotation) and shaft rotation. This makes it easier to adjust the rangefinder to get accurate results.

Vertical RF Alignment
Yes, you can DIY the RF patch vertical alignment if your camera is an M3, M2, or M4. But if your camera is an early M4-P, M4-2, or M5, you need professional help.
For cameras earlier than M6, you also need to remove the Leica reddot logo above the lens mount.
Yes, this is a nuisance and Leica deliberately introduced it to stop weekend warriors from adjusting their lenses. You can’t use any old screwdriver or Torx tool to adjust your lens. Only Leica makes and supplies an adjustment tool called “Adj. RFM4P, M6”, 1500-0000-1349 for about $US250.

More Adjustments
For those who want more details about the vertical and horizontal adjustments. Here’s some more information from the author:
The most common rangefinder adjustments include:
1) The rangefinder distance calibration (infinity and close-focus adjustments), and
2) The rangefinder vertical alignment
All these adjustments can be done without the top plate coming off!
Cameras use a red dot or a screw to adjust the vertical alignment. Early cameras used a simple adjusting screw. Later models use an eccentric cam that requires special tools.
Rangefinders use an eccentric pivot to adjust the ratio of rangefinder motion to lens motion. A short arm moves the rangefinder farther than a long arm.
Leica will sometimes do things at a Leica clinic. A technician takes about half an hour to make these changes. Other adjustments require the top plate to be removed.
These include making sure the bright lines are in the right place at infinity and close focus, and adjusting the mechanism that selects between each set of masks when a lens is mounted.
Most cameras require very little adjustment. Some cameras may need some cleaning and lubrication. Older cameras may need more work than newer ones.
