Timing Chain Guide Rail Pin Puller Set for BMW / Mercedes – M5, M6, M8

This specialized puller set is designed for removing guide rail retaining pins used in timing chain systems on BMW and Mercedes engines.

During timing chain replacement, guide rail service, cylinder head removal, or full engine overhaul, these pins must be extracted before further disassembly.

Since the pins are often press-fitted into precision bores, this tool allows safe and controlled removal without damaging surrounding components.

Tool Design and Operation

The puller is equipped with a ball-bearing mechanism for smooth and controlled extraction.

Depending on the application, the tool can be supported:

• Against the timing chain front cover
• Or by using the included support plate

This flexibility allows use even in confined engine bays.

Advantages

• Enables removal of press-fitted guide rail pins
• No need to remove radiator in most applications
• Controlled extraction reduces risk of damage
• Includes multiple adapters for broad compatibility
• Professional-grade durability and precision
