How to Avoid Failure Replacing a Front Crankshaft Seal: Example Shown On Older Mercedes Diesel

This is an overview of what is required to successfully replace the front crank seal in an older Mercedes Diesel. Principles apply to gas engines as well. mercedessource.com/store/sear... If you decide this is something you want to tackle yourself I have all the parts, tools, kits, and instructions to help you DIY.

Kent, What a great tool and your video instructions are always excellent for the DYI community !

[@jamesplotkin4674]

You deserve $150 for the set of custom tools you show just for your experience. Have you ever had a problem with the crankshaft sitting too low from main bearing wear, thus causing a leak from being imperfectly centered? On the multitude of gasoline engines I've had my hands on, I always re-surface the crankshaft and install new bearings just to avoid this problem. It's especially important to have healthy crank and bearings to avoid damage to the ream main seals, automatic front seals and the automatic front pump and bushing for the torque converter. My mantra... round and true is a good thing. It avoids leaks and preserves balance. ;-)

I don’t have a 240D but I still like this video ,,,,,😂😂 in fact all your videos are awesome 👏🏼

[@inovahightechltd]

Kent, you sure come up with some really neat tools! My humble request would be for two tools for W126:
1. Removal tool for the engine mounts
2. Removal tool for Starter on M117 engine
I guess you know why! Sincerely Peter

Thanx for video, you make it look easy

I love this channel I have learned so much from you.

thanks kent, i dont need it yet but i know i will some day

[@mikeabbonizio9892]

my 240d has a wet crank seal so this is on my list of things to do once it warms up!

[@arnhemseptember2009]

Great tools!

Fantastic

[@jamesluciani3284]

Can you do a video on the front water drains in the R107. A bit confusing. Thanks

[@tsitom3461]

Very nice! Driving in seals with a socket is something I never liked. I always worry about the seal being cocked and then leaking.

[@gueyg3764]

That works

[@Mario74hh]

I have a 1983 280E M110 suspected rear main seal do you have any videos for this ?

[@upstairzstudio8480]

thank you for the great video Mr. Kent. I own many of your tools for w123 300d .. I do need to change front crank seal on my w124 300d .. any solutions??

[@Mercedessource]

Sorry, I do not have any kits, tools, or instructions for that particular job.

[@pricelessclips]

Kent, What type of sealant do you use for the outside of the seal? Can you sell the red super sticky grease for the inside of the seal and sealant for the outside of the seal? Thanks

[@Mercedessource]

Aviation permatex sealant is what I use on the outside. I no longer use the sticky grease because I came up with a new tool to install the front crank seal that guarantees not rolling the lip. The sealant is included with the kit. mercedessource.com/store/617-turbo-diesel-engine-front-crank-seal-replacement-kit

[@vintage76vipergreenBeetle]

👍

[@jobeppe]

I'm just asking, cant' you install the race after replacing the seal? So the race slides from the outer part of the seal not tearing the lip

[@Mercedessource]

Super tight fit. That would probably be a sure way to pop that spring off on the back side.

[@felzke440]

@@Mercedessource Well, this answered my question. I was thinking the same thing.

[@Hunter-ld7nr]

I have a 1962 220Sb Fintail W111.012 Chassis with the M180 engine that has a leaky seal, does it also have a race that needs to be replaced? If so, do you sell those as well?

[@Mercedessource]

Yes, the race and seal are almost identical ( seal is slightly smaller) but the install tools work without modification. I am working on a kit now for the 1960's 6-cylinder engines and should have it ready in about a week.

[@Hunter-ld7nr]

@@Mercedessource Awesome, I will keep a lookout for that kit!

[@datadogie]

Easy when you know how.

[@titofernandezmeirino9832]

Hi Gentleman, if I do order the tools, would you be able to ship them to Europe? Thank you for your answer.

[@Mercedessource]

Please email my daughter, Kaia, [e-mail] and she will try to help. Thanks
