Like taking a cork out of a champagne bottle pretty slick 👍 only half as much fun 🙂

Another good video Tom. I’m like Big John, no OEM seal pullers here either. I’m not saying how I get them out, rougher than BJ. That’s all I’m admitting to😁😁

[@VintageEngineRepairs]

No I don’t know anyone else who has one I must be honest, at the price they are it’s a total rip of!!! I guess I was prepared to be ripped off to have the tool and enjoy using it though 😂🤣

[@almclean4835]

@@VintageEngineRepairs Hobby Motor will have one. Isn’t that right John Klem 😄

That’s right Al, it’s tough being our level of cool. 🤣🤣

[@marklk8787]

How can you be sure the bearing is good? I was taught to suspect a bad bearing when a seal is leaking and replacing the seal will only temporarily fix a leak.

[@VintageEngineRepairs]

No that’s wrong. If there is no play in the bearing and it’s clean and smooth it’s likely fine. The bearings, with good lubrication can last many decades, seals much less so.

[@Big_Johns]

Nice job Tom, us poor country boys can't afford those high fangled seal pull'n tools, we have to resort to wood screws and pliers. 🤣👍🏼

[@VintageEngineRepairs]

Good ole screw and pliers works very well, though it’s the tiny seals that can be a bugger!! Cheers for watching mate :)

[@Big_Johns]

Anytime Tom, always a pleasure mate!! 🙂

[@mr1pearl]

Yep

[@ronniebarker79]

Big shout to the drywall screws lol 😂 tom has all the updated tools where us have struggled lol

[@Big_Johns]

🤣🤣

[@niconine268]

It is great when one doesn't need to split the case to replace main seals. Otherwise it's like a total rebuild

[@VintageEngineRepairs]

Yes! It can get quite involved :)

[@willdubeast88]

If a flywheel side seal is bad enough will a 2 stroke engine not start?

[@VintageEngineRepairs]

It’s certainly possible!

[@eastcoastmostwanted710]

Can you test vaccuum with a normal compression tester?

[@VintageEngineRepairs]

Na, it has to have both

[@martinburgess4814]

Great to know i will have to get a tester thanks

[@gordhonor8941]

Your video was fantastic! The way you explained the vacuum seal function was so clear and easy to understand. Thank you

[@VintageEngineRepairs]

Glad you enjoyed it!

[@amelbye]

That seal puller tool has to be the best tool I've seen for doing such job! I'd like to buy one for use with all my motors, ranging from outboards to automotive. The original tool is $500 which is a bit steep - any link to a cheaper replica? Otherwise, I think it should be feasible to make something similar by modifying a bearing puller

[@VintageEngineRepairs]

Hey! Yeah it’s not cheap :/ I haven’t tried any clones of this tool so can’t recommend it I’m afraid :(

[@amelbye]

@@VintageEngineRepairs fair enough! How well does this tool work with different width shafts?

[@williammcilrath9828]

again a zery good informtive vid thanks brother BILL

[@VintageEngineRepairs]

You’re very welcome :)

[@VashStarwind]

I never even realized that shaft seals have to hold pressure/vacuum, I always just thought they kept oil from leaking out. Is that only for 2 strokes, or do 4 stroke oil seals also have to hold pressure?

[@VintageEngineRepairs]

There isn’t the same pressure in a 4 stroke engine as they have positive crank case ventilation. Their role is to hold oil as you mentioned.

[@VashStarwind]

@@VintageEngineRepairs Ahh gotcha. Thanks for the info.

[@aleks_jones]

tapered is the word you were looking for lol

[@VintageEngineRepairs]

Haha I don’t remember the context as the video is quite old now, but, thank you! Ha :)

[@watchthemaster5906]

Where did you get that tool?

[@VintageEngineRepairs]

Which one mate?

[@larrybui]

where can you buy the seal extractor tool?

[@VintageEngineRepairs]

Hey, either directly through stihl or you can get clones of theirs. No idea on their quality though!

[@jeffreybanks7128]

@@VintageEngineRepairs I have been told by multiple dealers,that Stihl tools are only sold to Stihl Dealers, and not to consumers!

[@alfredlyman2628]

I have a question, and it's not related to this video. Would you consider doing a video on a battery-powered lawn mower it's seems they are becoming popular, and I couldn't think of another you tuber that would come close to the way you would explain it, please consider it

[@VintageEngineRepairs]

Hey :) firstly thank you! I appreciate the kind words tremendously! Battery equipment doesn’t interest me I’m afraid. My love and passion is purely the internal combustion engine. Therefore, it’s best someone who is as passionate about battery as I am about engines, do that video. :)

[@niconine268]

Yeah great video. Totally on the money. Thankyou

[@VintageEngineRepairs]

Thanks :)

[@jbone1383]

You don't have to seal off the intake & exhaust ports to be able to perform a pressure test or a vacuum test? I'm confused 🤔

[@VintageEngineRepairs]

Yep, both intake and exhaust are blocked 👍

[@Non-Stick_Pan]

Hi, another great video. I'm a bit of a caveman and on larger engines I've just driven a self tapping screw into the seal when used the claw of a hammer or a small pry bar to remove it. Would you recommend that method on these smaller engines if I didn't have the special tool?

[@VintageEngineRepairs]

Sure! I have done so before :) just be careful, work slowly and use small screws lol

[@Non-Stick_Pan]

@@VintageEngineRepairs Thank you! :)
