Mercedes Engine Transmission Rear End Seal Installation Kit

Use to properly install a new seal without damaging it or causing premature failure

Item: TUL-SEATINSTALL
$19.75

There are challenges as well as perils when installating a new seal. If you are not careful the lip seal spring can pop off and you will never know it until the seal starts to leak again and you have to replace it! You can also damage the seal housing by trying to tap it in from side to side during seal replacement. Avoid sharp blows and drive the seal in straight with finesse!  This tool kit will save you big headaches as well as $$ down the road.

This installing tool has the following advances:  

Mercedes Engine Transmission Rear End Seal Spring Security Kit

This will prevent seal spring from popping off during installation

Item: TUL-SEALGREASE
$3.45

This is just what the doctor ordered when installing a new seal. This can prevent the lip sealing spring from popping off during seal replacement. When this happens you will never know it because you can not see the sealing spring once the seal is installed!!!  Talk about having to do the job all over again. The sad thing is that some shops could install the seal and the spring could come off unknowingly. If you have a shop install new seals in your older Benz specificly, you want them to use this grease on the back side of the seal to secure the spring!

This kit contains the following:

Mercedes Front Seat Back Net Pocket Repair Kit - W/ FREE Illustrated Instructions

Finally an inexpensive and simple solution to the sagging problem!

Item: INT-SEATPOCKET
$14.95

From my experience the only thing that goes wrong with the front seat back pockets is the top bungie cord that holds the net up wears out (loses its “spring”) and sags badly. When was the last time you saw a 1973 to early 1990's seat back netting that was NOT sagging??? Look at the before and after difference in a 1983 240D (image 1) It does not take a trained eye to know how much better the left one looks (fixed first) from the seat back panels in a 1990 190E.

Item: MRM-TRANSTUNE
$32.95
61x Diesel Automatic Transmission Tuning Manual
Lets face it! Diesel automatic transmissions can be troublesome, particularly those models that use vacuum to control shifts. This is largely due to the fact that diesel engines don't produce vacuum naturally. It has to be artificially manufactured. This is what makes diesel transmission tuning difficult. The numerous vacuum and pressure controls that were added to make it shift properly can create all kinds of problems when they fail or get out of adjustment.The big challenge in writing the manual was to clearly explain how to get all these controls working in harmony for the transmission to operate at peak efficiency.

If you own or are planning to purchase one of these popular wagons, I guarantee at some point you will have to deal with the SLS (Self Leveling Suspension) system.

Mercedes Monark Diesel Fuel Injector Nozzles-Best Engine Performance Upgrade

Of all the upgrades for diesel engines that we offer on this site, I believe changing over to Monark injector nozzles will give you more performance improvements for the money that any other single product. From our own diesels to the glowing reports we hear from our customers - you may have a hard time believing just how true this claim is until you experience it first hand! And Monark nozzles are probably the last of a breed. Yes, they are still manufactured in Germany...

Mercedes Complete MBZ Brake System Service and Repair Resources

Recently, I set out with the goal to provide our customers with all the resources they would need to troubleshoot and repair the brake systems on their own cars. As your favorite Benz ages brake problems will arise and they can sometimes be difficult to diagnose. Since brakes are a safety related system it is also VERY important that any repair work be done properly and with great care.

Applies to all models and chassis listed below:

Item: MRG-COMBBEP
$15.95
This 12 page instructional booklet by Kent Bergsma (8.5x11 page size) covers brake bleeding equipment and procedures for all model Mercedes from the mid 1950s to the mid 1990s. This covers chassis Ponton 110 111 112 113 108 109 114 115 116 107 116 123 126 201 and 124.

This new easy to understand guide will walk you through the different ways to bleed your brakes and the equipment needed to do the job right. Brake bleeding is something that no sane person finds enjoyable. It can be messy and often involves painful contortions to access the bleeder screws. There seems to be varying opinions as well as a bit of black magic involved with the bleeding process. It may be more of an art than a science. Sometimes the procedure works perfectly, and then other times it seems like you end up with endless air in your system that just wont come out. The information contained in this booklet will eliminate some of the mystery and give you the knowledge and confidence to do the job right the first time. Covers safety tips, types of bleeding equipment and 4 different ways you can bleed your brakes.

Mercedes 201 124 126 Chassis 103 Engine Serpentine Drive Belt Tensioner Rod

Item: GEG-COMTBAR
$22.50

Mercedes 617 Turbo Diesel Engine Anti Rattle Kit

1978 to 1985 TURBO 300D 300CD 300TD 300SD with air filter housing mounted on engine

Item: DSL-123ARK
$26.50
300D 300TD 300CD 300SD Turbo Diesel Engine Anti Rattle Kit

Works only on the 5 cylinder turbo engine from 1978 to 1985 (116, 123, 126 chassis). 300D 300TD 300CD 300SD. Does not work on some 1985 models with trap oxidizer (air cleaner mounted off the engine). If you own or have owned a 116, 123, or 126 with a 617 turbo diesel engine for any length of time you are probably very aware of the air cleaner shake and rattle problem (except 1985 models with trap oxidizer). Rubber mounts loosen up or tear and the mounting brackets seem to break way too often. With this kit and instructions I hope to help you eliminate or at least drastically curtain this common problem. After working on literally hundreds of these engines I have found that just replacing the bracket and the three rubber mounts is not the answer.

Mercedes Bosch Factory 135 bar Turbo Diesel Fuel Injector (Recent new and tested)

Item: VAC-GREENMOD
$59.95

This is the GREEN transmission vacuum modulator found on most of the models listed above. This unit has been upgraded from the original for better shifting performance. This new part has a stronger vacuum containment chamber and the thrust pin included is made with a new material to eliminate fluctuations in pin length during extreme temperature changes. Internal spring tension has been increased to improve cold start shifts from 1st to 2nd gear and reduce flaring when shifting between 3rd and 4th gear. WARNING: There are other things that can cause problems with poor shifting, so there is no guarantee this new part will fix them. But due to the cost and ease of installation this is a good place to start.

Mercedes Ultimate Flexible Brake Hose Removal Tool

This flex head flare nut wrench will do wonders!

Item: BRK-BRAKEHOSEWRENCH
$9.95

 One of the hardest parts of replacing a flexible brake hose is loosening up the hard metal line without rounding off the nut. These are on hard and over time the top fitting can take some real force to loosen. You will need a flare nut head wrench to loosen the nut without damage. We have one that even has a flex head to allow better access to the nut - which is sometimes not very easy to get at. Kent's favorite brake hose wrench!

No rips or tears, padded is good and stitching is all intact. Will require special boxing for shipping - suspect shipping charges to be $125 to $200 depending on your location. Contact us if you want to purchase.

Mercedes Diagnosing Diesel Engine Excess Smoke and Lack of Power

The smoke is trying to tell you something. You need to pay attention and act accordingly

Smoke coming from a Mercedes diesel indicates that something is wrong with the engine and/or related systems. This should be taken as a warning.  If not dealt with, the problem (s) causing the smoke will potentially result in high repair costs later or it may shorten the life of the engine. If you take your high mileage diesel into a shop to fix the problem it could end up costing you thousands of dollars. In most cases the cause of the smoke on these old diesels is due to more than one problem. The only economical way to fix the problem and make sure it is done right is to do the diagnosis and repairs yourself.

Mercedes 1986 and 1987 300SDL KKK K-24 Turbocharger Assembly Used

Needs Rebuilding - An excellent and hard to find core if your turbo is totally worn out

Item: DSL-KKKTURBO
$165.00

This turbo is a complete unit as shown. I can not guarantee that every last bolt is there but all the key components are. Excellent bushing bores in the center section and in the compressor housing. The turbine on the turbine shaft is badly worn on the vanes. So it will need a rebuild kit, a new turbine shaft and wheel and a new compressor wheel. Sorry we do not carry parts for the KKK turbos. What you see is what you get. Price is right.

There is enough room in the case to add some gloves and tools that you would need to change the filters on the open road.

Mercedes Jolly Green HD Super Gloves Box of 50 ( 25 Pair )

As used by Kent Bergsma in all his latest videos - best ever - Diesel owners need a whole box...:-)

Item: TUL-BOXGRNGLOVES
$34.95
$29.95 On Sale!

Kent started wearing protective hand gloves back in the day when only latex was readily available. When nitrile came along he was elated and has closely followed improvements in these gloves over the years. Recently he discovered what he believes is the ultimate glove when working on cars - especially old diesels! If you have watched any of his recent videos you will recognize them by the dark green color.

The advantages of these over other nitrile gloves are numerous:

Mercedes 602 and 603 Diesel Engine Breather Hose Fix Kit w/ Instructions

A good alternative to the expensive factory replacement

Item: DSL-60XBREATHER
$19.50

The original rubber grommet and plastic elbow will become brittle over the years from the heat of the engine. When you go to remove the breather it will often just break off in your hand! The hard seal allows oil to leak causing a mess around the front of your valve cover. Ordering a replacement from the Mercedes dealer may come as a little price shock, so Kent came up with an inexpensive alternative.

This kit will work on the 1986 and 1987 300SDL, the 1987 300D and 300TD and the 1990 to 1993 300D 2.5. It may work on other models as well. Please view picture closely to confirm. Kit contents are as follows:

Mercedes Heavy Duty Bungee Cord - 1/4" x 5 Meters

You will be amazed where you can use this stuff!

Item: TUL-BUNGEE
$2.50
See Kent's video on his Fab Five. This cord is super strong and easy to tie off without the knots loosening up. Use it to hold up falling mufflers, hold the trunk lid down when hauling oversized loads, tie off loose things in the engine compartment - even keep your dog from running away - you can have some fun with this one!!!

Mercedes DIY Super Tape: One of Kents Fab Five

This unique tape sticks to almost anything and lasts and lasts through extreme environmental conditions

Item: TUL-ZIPTAPE
$3.25

One of Kent's top pet peeves is poor performing tape. All the promises of duct tape, gorilla tape, electrical tape just don't cut the mustard - especially when subjected to hard conditions of temperature, sun and moisture over time. This tape was designed for the home construction industry to seal out moisture and air in the underlayment system when framing a home. You can not believe how this stuff sticks. It does not tear. It stretches and forms around slight compound surfaces.
