Showcase your homebrew MB related tools in this thread

[R129 UK]

Inspired by the "What’s your best buy DIY garage tools?" thread here.

I thought it would be an idea to have a place to show off any MB special tools you have made or adapted yourself for a particular application.

Often, special MB tools listed in the technical documentation are NLA or expensive and a bit of ingenuity can create a workable alternative.

My first contribution is a set of M119 camshaft pinning tools MB part number 111 589 03 15 00:



Really simple to make and could be made with M6 studding and threaded collars instead.

The centres of the pins is ~138mm but they are fully adjustable.

Tool 2 is an injector puller which I used on my OM642.

The injector end swivels almost 180° to allow easier access to the rear injectors when using a slide hammer:

Tool 3 is for electrical diagnostics, specifically finding a known parasitic current draw or checking the current draw of a circuit for troubleshooting:



Cut the fuse through the centre section between the blades and solder a test lead to each side which can be connected to a Multimeter in series.

My DVM has 20A over current protection. This device should not be used to fault find an unknown issue causing a fuse to blow as it could introduce much greater current than the components can withstand.

The same principle could be applied to torpedo fuses I think.

I’ll play.
First, my very crude tool to R&R the fan when replacing the fan clutch. $8 worth of steel from the big box home store and some lousy welds.


And second, my custom shift bushing installation pliers made from the cheapest vise-grip style pliers I could find, a large washer and a 1/4” flange bolt.

Welds look good enough to me, Glen!

One day I'll own a welding machine/tanks again...I keep repeating.

@Glen,
Your crude tool worked great on my fan clutch! Of course you were operating it.
