Super Easy Crankshaft Seal Removal

Using a well known technique for removing a crankshaft seal from the crankcase without having to take the engine apart - MacGyver style!

Great job! I like how simple and straightforward this video is. People who don’t like this drilling method. You can simply use compressed air, vacuum, or wd40 to remove the metal dust before actually pulling the seal out. This is a great way because you don’t run the risk of scratching the crankcase with an edged tool.

If you use this method (and I have) you must use a magnet to remove all metal fragments before pulling the old seal and then again after the old seal is removed. The area must be free of any metal fragments as the smallest fragment could damage the replacement seal.

Thanks for the tip. Didn’t realize the size was on the seal!!!!

Or... you could do what I've been doing for 40 years. Jam a flat screwdriver into the rubber part of the seal, pry sideward and downward on the head of the screwdriver, and the seal will come out of it's hole. No drilling or metal dust, and much less time spent messing with it.

However, you did press it in nicely - with a well-designed tool. ;)

Been doing this on snowmobiles for 20 years. Not drilling on mine, too many metal shavings. A good sharp edged screw driver pounded into the seal at an angle will allow you to pull the seal out. John Deere actually shows this in the service manual.

One long sheet rock screw and a claw hammer works perfectly too!

I'm face with an OLD Evinrude outboard whose seal is leaking and creating all kinds of idle problems for me. The official tool to remove this is $50 (minimum) from the sources that I could find and I don't intend to remove a whole lot of seals after I replace this one so your method is likely to save my bacon. Thanks.

Use silicone grease or paste on "rubber" seals, bushings and other parts not regular, oil based grease.

Those metal filing from drill are great for bearings

I've heard of it being done that way, but, never tried it or seen it done before. Nice!

As soon as you score your your shaft with the drill bit when it wanders the whole thing is screwed.

Self-tapping screws save drilling, make fewer chips, and are convenient to use with common slide hammer pullers.

For the people that are just saying, just use a flat head screwdriver or use a puller. Now I got a hardware store guy saying the same thing he doesn't understand. It's metal, you can't just stick something in there. It's hard as a rock. You have to drill holes. Nobody cared to warn me about this of course. And all of the timing belt videos of course. Just skipped literally how they got the crankshaft seal out. The guy at the hardware store is like. Just take out the shaft. I give up. It's always when I'm working on my car I have these problems. Yet, I can search through 10, 000 forums and videos. And because the people in the video didn't want to show how it's done properly or how they run into problems. You lose time. It's very important.

You can't just jam something that's hard as a rock. It's a crankshaft seal. And by the way not all seals are the same. You can't find screws as small enough as this person has to screw in there and stay. Then FEAR of making a mistake makes the job not get done (oh you can damage this and that) (okay than you do it, it then like the slightest little nick, now they say it's on the shaft and not the outside of the shaft. Then a person say it's both, you can't win. And also, not selling tools you need and having to wait an extra 5 to 6 days because something goes wrong. There should be a something goes wrong! In videos that people do.

Looks like a good way to risk scoring the crap out of the crankshaft.

[Hackerone]

buddy my two storoke not getting start and getting misfire is this reason behind it crank oil seal leaking ?

[chucklucas]

Use a over size dental pick works great

[Gogetter]

I must’ve watched a different video than you guys. what metal shavings? Good vid bro always nice to see how others tackle the job!

[PCG]

Switching mine out tomorrow guys. Do you have to drop all the oil out? Read on some yes but others say it's higher than oil line and only accures when oil is in motion so no need?

[kenjimoto]

If you don't want to see metal shaving just use a small punch to create a small hole for the screw to start. I wouldn't used a self tap screw. Drilling is too risky.

[poseidon]

or just take out the two screws on the stator plate and do it the proper way, so theres no metal shavings in your engine.
