Photo DIY- Lubricating Door Locks & Engine Hood

Please note, this applies to W460, W461, and W463 Gs.

Background: I took my 500 GE in to local dealer that works on my G55. For some reason, they can see the vehicle on the EPC, but NOT on the WIS.

I explained to them that it was essentially no different from a Preventative Maintenance perspective compared to a U.S. G.

That being said, this small service was something that they did not perform.

After spending the time to read through the G maintenance manual, I thought this tutorial would help other members.

Step One: Gather Materials.
We will be using:
A) MB Autowash or similar auto shampoo or Dawn dish detergent
B) Terry Cotton rag / hand towel / red mechanic's rag
C) Disposable Drinking Cup filled with hot water
D) 1/4 Inch Acid Brush (Available at Home Depot in a 3 pack) ---> http://www.homedepot.com/webapp/catalog/servlet/Search?storeId=1005... also at www.topgunsupply.com
E) New, Fresh Motor Oil (Mobil One, Fully Synthetic 0W40 in my case)
F) Lubristyl Oil Pen
G) Castrol Viscogen KL300 or (what I used) Optimol Paste White T
H) Mercedes-Benz Long Life Grease

Part One: Lubricating Door Locks / Latches
Step One: Wet the terry cotton or mechanic's red rag in hot water. Select which door latch you are going to start with. Use the hot water on rag to clean off the old grease and grime that is on the latch.

Step Two: Take some detergent cleaner (I used Mercedes Auto Wash) and apply a little to the rag in concentrated form. Dap the detergent soaked rag in hot water, to wet it slightly, yet don't soak it as you want to keep the cleaning power and concentration high. Go over the latch again with the detergent and make sure it is clean.

Step Three: Wipe dry with clean rag.

Step Four: Lubrication. Mercedes originally called for a chain oil from Optimol called Viscogen KL 300 to be used on the surfaces of the door lock latches.
Read here: http://www.castrol.com/liveassets/bp_internet/castrol/castrol_advan...
I have deviated from this. I chose to use Optimol Paste White T. This is just my opinion, but I believe chain oil to be a little on the thin side for the application and I believe the properties of the Paste White T to be better for this application. http://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/D44B3595EEBCE...

Step Five: A little trick I learned from a Special Warfare armorer when maintaining crew served, heavy weapons. We would apply TW25 using acid brushes (see links above) as this would help to dispense the lubricating layer evenly, and completely, while getting into nooks and crannies. Keeping the layer even and thin was important with TW25. Optimol Paste White T is similar in consistency to TW25, the acid brush really helps with application and keeps your fingers clean.

Step 6: Repeat for Side Doors and for Rear (5th) door.



EDIT: To be continued. Need to download the rest of the fotos.

RE: Photo DIY- Lubricating Door Locks & Engine Hood

Even better for the latches is the MB Silicone Paste, P/N A.000.989.84.51:

http://fourbyfourclub.com/W463Tools/463SiliconePaste.htm

It is thicker and stays in place to do its job. It's pricey as the devil and a jar will last 10-15 lifetimes; but ever since I started using it on that very prone to rattle and clunk rear door (and did a proper adjustment of the latch), the clunk and rattle have not reared their ugly heads again.

For the hinges, I wick Break Free CLP into them. Works extremely well.

I use Vinylex on the rubber gaskets around the door.

No squeaks or rattles in my doors.

PS - Thanks for reminding me to do this before I leave.

Re: Photo DIY- Lubricating Door Locks & Engine Hood

Dutch, how did you do a "proper adjustment of the latch" for the rear door? My front doors could definitely use a tiny adjustment. What's the procedure?

H1LM - thanks for the post.

RE: Photo DIY- Lubricating Door Locks & Engine Hood

Thanks for taking the time to post. I really appreciate it.

One small point: I think the "concensus" was to run all of the DIY posts through the "regular" forum so they may be "vetted" by the group, prior to being placeed in the DIY section. Sooo, if you don't mind, I will bounce this up one line to the G-section...

Perhaps I'm con-fus-i-ated about "where" these various lubes are suppoed to go on the mechanisms, but here is "my" interpretations:

http://www.pointedthree.com/disc/forums/showthread.php?tid=19434&po...

If you go to the bottom of the post (bypass the Lock Repair), you will see the MB Recommended lubes for Tumbler, Striker Plate-Lock Mechanism Interface, and the Striker Plate-to-Striker Eye mating.

I think the Viscogen is designed to lube the Plate/Lock interface, but I could be mistaken.

Re: Photo DIY- Lubricating Door Locks & Engine Hood

I need to update this as I just bought the Silicone Lube that you and Dutch use (to the tune of $45.00 USD) and am going to try that. My rear door was squeaking with the Optimol to be honest. Will update with pictures this week.

Be sure to not forget some the the Lube spots on the Rear Door:

Re: Photo DIY- Lubricating Door Locks & Engine Hood

The rubber piece to the right hand side of the rear door, lower part of the body...Currently, it has some type of graphite or moly grease on it that is grey/black in color. Any idea what they used "in the past" for this application?

Don't know.

I just cleaned it all out, and changed to the WunderLube. Quiet happiness ever since.....

Actually, G-AMG had a thread similar to this that was already posted.

You are German, so preventative maintenance and lubrication comes naturally to you. Also, it is performed at dealerships routinely.

In the United States, this is a step often skipped.

Not sure why you would post something derogatory when this is in fact G-Wagen maintenance related and something that many fail to do?
