Danger, Warning:
NEVER use any timing chain that comes with a retaining clip master link, it is a gasoline engine chain = it will fail FAST in a few hundred miles/thousand miles.
Need Automotive Grade Prozac = timing chain

1984 190D-2.2 5-speed

The temporary link pictured is actually just the master link from the old chain (which was installed long ago, before Mercedes changed engineering direction and mandated crimping as the only recommended method for linking the chain).

The clip-on style of link in a MB diesel rated timing chain has not been available for many years.

The wood block is a homemade substitute for the proper Mercedes tool, it helps hold the chain to the camshaft sprocket.
Obviously, a wood block is not as good as the factory tool but it is better than no tool at all
This one is cut to fit the 601 diesel engine (and most likely the 602 & 603 as well) to help you guide the chain in.

Mercedes sells temporary links for rolling in the chain (part number 602 589 02 40 00, Listed as "Threading Link Set (temporary) for Diesel/Gasoline Engines").


The crimping tool works on ALL MB timing chains.
You should make a wood block to fit your engine.



The picture with the blue circle shows (from left to right):
* A factory crimp
* Crimp with home made tool
* A virgin pin

The other picture shows the pins after being peened.


Please read these for more data on correct timing chain CRIMPING.
