Glow plug service tool kit - PeachParts Mercedes-Benz Forum

JHZR2 · #1 11-22-2010, 12:08 AM

Hi,

There are a few good threads on testing and working on glow plugs, but I haven't seen much on the best tools. I saw one thread where a drillbit was welded into an old glowplug...

But what is best practice? Just a drillbit? What size, should I get some sort of brush to work the holes like the site from up in Washington sells?

Is it smart to get grease in the prechambers, or am I better off maybe dipping the tool into oil which might have fewer ramifications?

Should I blow compressed air in or such vacuum on the hole before cranking to blow them out?

Thanks!

Confused, are you looking for a tool kit or probing for a market?

Looks like you have seen the M*******Source ad.
The little gadget brush is not need.

You do not need the Instructions because our do-it-yourself section has ample instructions.

The Factory Made Glow Plug Reamer has a 7mm outside diameter bit on it.

The use of Grease is recommended by the Factory Service Manual because ti traps the reamed out Carbon and holds it in the Grease. The Grease is not being used as a lubricant.

In 2 of the below pics I used Vasoline so that the Carbon would show up. However, except on a very cold day Vasoline is too runny. I normally use Wheel Bearing Grease because that is what I have; the service manual does not specify any particular Grease.

In one of the Pics I show my Home Made Glow Plug Reamer on the Left; a Glow Plug in the Center and a Factory made Reamer on the right.
On the ones I make I used a 6 Flute (groove) Reamer on the end.

The only thing you need is a glow plug reamer, which you can get by clicking on the "Buy Parts" link at the top of this page and then selecting "Special Tools." The last section in Special Tools is for Mercedes diesels and there are several reamers available for the various models.

No one has tested a Glow Plug Reamer against a Drill Bit or any other of the cleaning methods to say which works better.

People seem to pic what ever method they want to use and stick with that.

But, the Factory Service Manual and from what I have read the general consensus of forum members is that it is believed cleaning the Carbon out with something extends the life of the Glow Plugs.
From my notes Hunter speaking of Glow Plugs dieing due to Carbon insulation

Per my oher hard starting thread, Im doing research to have all the right tools to do the job beyond properly...

There is no doubt (in my mind, anyway) that a drill bit, twisted by hand, will do the job on the 616/617 engines. It might take a little more effort than the reamer, but it is far more cost-effective for the occasional user.

No offense intended, but clearly expressing this in the initial post and thread title really help. When reading the title one would think you are either saying "Hey look what I found" or "who wants to buy one?"

Perhaps a better title is "What tools are needed to service glow plugs OMxxx). Followed by a little background info and intent in the initial post.

This is something I am going to have to do soon as well and therefor helpful info. I am curious what the available reamer costs here? All this commentary about cheap options and no part numbers or prices or even a link to what is offered on PP.com.

If that is the best that you can do when it comes to grammar and punctuation, your critiques of other folks' posts are destined to offer more entertainment than enlightenment.

Is your search engine out of fuel?

Or was the wording of this earlier post inadequate for your needs?

That link confuses me... There are two tools, one for 602, 603 and 617.95, and another for 615, 616 and 617 engines. One seems to be 12x1.25 and the other 18x1.25. Is one right and one wrong for a 617.952?
