In this video Kent shares his technique for removing a padded steering wheel on most 107, 114, 115, 116, 123, 126, and 201 to 1985 chassis. These are the models WITHOUT an airbag.
Groaning, snaping and jammed door check straps are a common problem on the older models (up through 1995). This is primarily due to age and lack of lubrication. Newer models will soon start having similar problems. Rain water getting inside the doors is the big killer.
Diesel engines make noise. Some ticking and rattling is normal and not something you should be concerned about. Certain loud knocking or rattling noises could be a sign that something bad is happening to the engine, especially if the noise comes on suddenly.
This is part 2 of a 4 part video series Kent has done on repairing the power tilting sunroofs on the W201 W126 and W124 chassis built from 1986 to 1995. Part 1 covers removal and replacement of the sunroof panel and headliner.
If your transmission is shifting too soon it can really rob your car of power and acceleration. If it is shifting too late it can be very loud and annoying and even affect fuel economy.
To many people, automotive electrical systems and testing are a big mystery. It is not as complicated as you might think.
The driver's side W124 under dash panel can be a little tricky to remove due to all the hidden fasteners. Without knowing where these are and how to get to them, removal can be frustrating and it is easy to break the plastic covers.
When working under a Benz having the right equipment to put the car and hold it safely up in the air is very important. Always think safety, and the type of equipment and how it is used plays the key role in keeping you safe.
You will need to remove the W126 chassis center console upper wood panel when replacing the climate control switch panel, replacing any of the upper switches, replacing burned out light bulbs and /or when remove the center console or the upper dash.
When an old Mercedes ( or any other car for that matter ) has sat idle for over a year it can be a challenge to get it safely back on the road again. If it has sat idle for more than 5 years you may find it difficult to even get the engine running.
In this 10 minute video class Kent shows you what you should initially look for when checking out an older Mercedes for sale. He routinely does a quick 3 to 5 minute walk around to determine if the car passes his priority three part test.
Those three areas on inspection are:
There is nothing better than a good buff and wax to bring out the shine on an old Benz. Particularly if the car has not been waxed in a couple years! The results are directly related to the amount of work you put into it.
Why would you need to remove a fuel tank? If it is heavily rusted or contaminated sometimes it is just easier to find a good used fuel tank and replace it. Trying to clean a heavily gummed up fuel tank is a real challenge.
Malfunctioning and failed power window regulators (mechanisms) are so common on older Mercedes that Kent can almost guarantee if you own one and drive it regularly you will have to fix one at some point.
In this video Kent shares his secrets on how to make the inside of an old Benz look like new again. Now granted, you must have a reasonably good car to start with. He is not going to show you how to reupholster, change seats and door panels, etc.
In this video Kent will walk you through the step-by-step procedures he uses when diagnosing and repairing an older Mercedes diesel engine that either won't start or is very difficult to start.

In this detailed step-by-step 26-minute video instruction, Kent will show you how to correctly install the B1 and B2 piston assemblies, check them for proper operation, and measure the required "free-play." He will also cover other items you will need to install on
Now, for the part you have been waiting for —and perhaps the most critical. If you forget to install even a single small needle bearing or a couple of thin washers, you could encounter some serious problems.

This is a comprehensive video (30 minutes long) that provides an in-depth explanation of testing and adjusting the modulation pressure in the 722.3 and 722.4 transmissions.
Out of years of frustration trying to adjust the modulator during a test drive, Kent came up with a better and faster way to make adjustments by just "reaching" under the car. This little device replaces the plastic cap during testing and adjustment.
Kent will show you the procedure (along with troubleshooting and testing tips) with a 722.3 Transmission on the bench.
In this 13-minute session, Kent will open up the planetary gear assembly with the one-way clutch and show you how to put in the new seals. This one is a little bit tricky. You have to be careful not to knock the clutch assembly apart. It also takes some effort to get it all back together.

In Part 7 of this transmission rebuild training class, Kent will prep the drums for reassembly with the new seals. Installation of the piston in the K1 drum can be particularly challenging.
These are probably the most important internal seals that you need to replace. Pressure loss in the K1 and K2 is probably the primary reason for delayed shifts and flares between shifts. This is the first part in resealing these important brake drums.
In Part 2 of this training series, Kent will show you what you will want to inspect before you begin ordering parts for a transmission overhaul. In most cases, you will only need gaskets, seals, and clutches, but you want to make sure. 72234CLASS
