You attach these to your 300D, 300CD, 300TD, 5-cylinder engine and turn the engine over with the starter motor for cleaning and testing.
These original masts are NLA, and this is from Kent's 20 year old stock and was only used a few months. No damage. super smooth operation and super straight. The TOOTHED tail was used on some antennas from 1983-84 up until the early to mid 1990s.
These original masts are NLA and this is from old stock Kent has had in storage for 25 years.. The smooth tail was used on antennas from the mid 1970's up until around 1983-1985.
We know someone out there is going to want these. Priced cheap as they will need to be picked up. Too expensive to ship. Please do not try to check out. Email us if interested.
This is a short 5-minute video instruction where Kent demonstrates how to precisely install a hood star wreath from the kit we offer. Note: Multiple colors are now offered for you to customize your own Benz.
We give you options. Look at the images below and you can decide what color you like best to put on your hood star. You can choose, red, gold, silver or a combination of the two. Please watch the video instructions BEFORE installing.
This is a SINGLE replacement bulb if one of your Hella headlights has suffered damage. It wil come with a new H4 bulb. We realize you may not need the bulb, but this is the only way we can sell it.
Kent's highly detailed xx-minute video on how to remove the K3 and pump assembly from the front of a 722.3, take it all apart to gain access to the big pump O-ring, replace it and the torque converter seal, and put it all back together again.
Kent will share his knowledge from years of doing pressure tests on these old transmissions. Don't be afraid to do this. It is definitely a entry level DIY procedure.
Too much pressure and you will blow the seals. Too little pressure and you will wear out the clutch packs. When installing a new vacuum modulator on your transmission, you most likely will need to adjust it. There are two ways to do this.
these are almost gone and word has it they may no longer be made. ONE PER CUSTOMER ONLY!
This is unique to most 1985 OM617 CA models with TRAP OXIDIXER. Only fits models with the air filter mounted OFF the engine, behind the passenger side headlight assembly.
In this short video Kent will explain how to use his stud repair kit (see relaed below) to fix damaged oil filter threads in the top studs that hold the cap on.
If you discover a stud loose when doing an oil change on your 1977 240D 300D 300TD 300SD here is the kit you will need to fix it properly. Even comes with new semi-locking cap nuts. Watch Kent's YouTube video below to learn more.
The kit comes with the following:
This is one of the most common leaks we have seen on these transmissions over the past 25 years. If you are discovering big puddels of red transmission fluid on the ground at the front of the transmission I can almost guarantee it is the front pump leaking.
This is Kent's master kit for solving a number of transmission-related shifting problems. Please note it will not solve them all, particularly if your transmission is worn out.
You should change this crush washer every time you change your engine oil. Good to have some spares on hand.
Good condition as shown.
VERY CLEAN rust-free set of rear springs removed from 300TD wagon. The car was sitting at the correct ride height. These appear to have been replacements in the not-too-distant past.
When you are resealing or rebuilding, or even just working on the B1 piston, you need to check the release pressure. This is done by measuring the distance the piston has to travel before the brake band clamps onto the K2 drum. This should NOT be neglected.
PLEASE NOTE: As stated earlier, Kent does not cover the overhaul of the valve body in this video series. That could be another long series all by itself. He will show you how to make the K1 accumulator upgrade.
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.
There are several important seals and O-rings that need to be replaced before proceeding with reassembly. In this 26-minute video, Kent will go down both the right and left sides of the case and demonstrate each one. 72234CLASS
In this 19-minute session, Kent will remove a rear oil pump from an early 722.3, disassemble it, and demonstrate some of the challenges associated with resealing it. 72234CLASS
In part three of his 722.3 video class, Kent will give you his recommendations of some tools and supplies you may need when you go to tackle this job yourself. He will also give you recommendations on additional manuals you should download from the internet. The video is 21 minutes in length.
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.
This item is non-returnable, so please only order if you can live with the differences in stitching and ribbing. Thus, it is priced accordingly. Best for someone who has such a bad palomino driver's seat that he will find this more than acceptable.
PLEASE NOTE: This should be used in conjunction with our modulator pressure test kit (see below). It can be unhealthy for your transmission to just "guess by feel" where the T-pin should be turned.
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.
Kent will walk you through the steps to remove the drive shaft SAVELY. Replace the center bearing and carrier on the bench / vise. And finally, replacing the drive shaft correctly back into the car. This applies to the R107, W116, W126 and W124 chassis. The example here if from a W124 300E
In this detailed step-by-step 20-minute video instruction, Kent will take this unit apart on the bench and demonstrate how to install all new O-rings and seals. 72234CLASS
In this xx-minute video, Kent will explain how to set up and use the different components in his kit (see below) to test modulation pressure in a 1981 to 1995 automatic transmission. This should be done when replacing the modulator or after rebuilding a transmission.
PLEASE READ CAREFULLY BEFORE ORDERING!
PLEASE ORDER THE UPGRADED KIT BELOW for your 1981 to 1985 turbo diesel Mercedes.
This is an improved factory upgrade for the older 722.3 transmission valve body up through 1990. Later models were revised and this upgrade is not required. The accumulator parts you will install are Genuine Mercedes.
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
In this first class lesson, Kent will take apart a non-shifting transmission that he removed from a 1987 300E. The video is 23 minutes long, and you will get to see how everything comes off and out of the transmission case to leave you in awe of what lies inside.
Green top modulators are no longer available NLA. It is difficult even to find good used ones. Hard to believe we still have one. Kent found it hidden away in the shop the other day and fully tested it. The long pin is included and it has a good solft black rubber cap.
Three seals in each drum need to be replaced. Only the bottom "hidden" drum seals in Viton are included.
This will work for almost all 4-speed automatics from 1981 to 1995. This transmission overhaul tool set is custom-modified here in our shop at MercedesSource. We make it to order, and it may take a few days to ship. It contains five tools.
Study the picture carefully. This is exactly what you will receive. Only one. No left side available.
VERY limited stock. These are the exact fuses you will receive.
In this detailed 30-minute instructional video, Kent will walk you through the process step-by-step of how to install the circuit boss and associated wiring to be able to power your auxiliary boost fuel pump and your fuel boost heater when completing your STC 100 conversion.
Kent calls this his "flowglow" because it is a straight flow-through fuel heater that uses a glow plug to produce the heat. Since the glow plug is submerged in vegetable oil fuel, it is very efficient and will last a long time.
In this xx-minute instructional video, Kent will show you how to install his pre-fabricated, ready-to-install fuel boost pump kit for the W123 diesel Mercedes.
