I blew up the ported Stihl 038 Magnum!!

It's true, I blew up the 038 magnum!!
let's dig into the saw and see why it failed!!
Thanks for watching!!

[@buggiemanc3944]

Tinman I know I’m late to the party here on this comment. My experience on those old Stihl that have went through multiple heat cycles. The paint / powder coat is fragile to certain chemicals I.E carb cleaner and breakklean it’s like putting paint stripper on it. After exactly the same thing happened to me on a 50 year old 031. I only use either / starter fluid to clean the inside of the case. It does seem to permeate the paint or reduce the molecular adhesion to the magnesium it doesn’t peel after the wash. . I hope this helps. Thanks for sharing your Kraft.

[@colvinwellborn]

One of the Farmertec kits I got, I think it was the 365/372 kit, had a horrible paint job and it was flaking off everywhere including in the crankcase. Took me a long time to scrape and wire-wheel it all out of there. Glad I did though!

[@mrxlh]

Glad you posted this, I have a build going back together with questionable case powder coating, I’ll remove it….

[@matthewziegler9756]

Appreciate you tinman! You and some other builders have got me started in building saws. I built one, love it and addicted. The way you explain things is perfect for me. Im too a visual learner not to smart in the book but I manage. Lol. You are great person and wonderful father.

If I rebuild a stihl I think I will take that paint off the inside. Big thanks for the heads up on this one.

[@dustingambrel3428]

I'm building an 038 right now almost done with it . I blasted the case & painted it with VHT high temp whit . But I sanded the paint out of the crank case. I also did port work & changed the exhaust timing by 7° I aslo took the squish down to .032 to raise the compression. I really have learned a lot from your channel tinman Thank you .

That's great the family is great! Love you brother! And STOP THANKING US FOR YOU GIVING OF URSELF! THANK YYYYOOOOUUU!

[@jimhofoss9982]

that’s a shame! why would they powdercoat the inside of a crankcase? I don’t see the benefit, a nice polished finish would be just as good, no? I know you’ll do good to that saw again…thanks for the insight! It’s a new one for me, but I agree with your analysis. Always something new to learn! cheers!

Aluminum oxidizes very rapidly especially bare polished, I can see potential for corrosion which equals particulate in the bearings. Just a thought

Saw cases are magnesium and corrode much easier and faster than aluminum. Just humidity could completely ruin the inside of a saw if it sat long enough if the case is bare.

[@kylecromp319]

Myself personally when i pull a saw down to r anything i wire wheel all that paint right off then this does t happen and i figure it also helps keep the fuel atomized kinda like leaving the intake a little rough

[@cargotoolshop5319]

Timeline for you guys, first 038 had a 48mm piston with no chain brake and it had points, it was a very modern saw with old technology, then came the chain brake and electric ignition and 50mm piston, called the special, this was probably the most widely used 038, very popular saw, and for a short time they made the hotrod saw called the 038 magnum, it had a 52mm piston and was as modern technology as the 440 and 460 that replaced it, my favorite saws of all time

Hey Tinman! Congrats on the baby! I work at Husqvarna dealership in New Hampshire and we love watching you! I have an antique Husqvarna 77 that runs and cuts great, I was wondering if that would be something you would like to port and mod for me? I would love to watch it done on your channel and it's a really neat saw for you to show your viewers. Obviously I'm not looking for anything free, I will pay you to do it but hope you can do it and make a video/videos on it. If not ,no worries just thought it would be a fun project saw!

That just reminded me of my 77 with a bow bar I have in the back of my collection! I need to get it out and restore it soon.

[@timwoodger7896]

Im gutted for you Tinman but I’m looking forward to seeing how you split the casing ! I most definitely think you should put a 381cylinder on her. I don’t know what the hyway cylinders are like but my farmertec 381 transfer ports are a lot bigger than what the oem mags were. All the best Tinman 👍

Thanks TinMan, , , WOW, you have the strangest things go South, thanks for the video.

[@robertdixon4554]

That powder coat is a weird thing , I had a freshly rebuilt MS260 lock up on its 3rd heat cycle … what a pain , mine was eisier to diagnose as I had a HUGE chunk stuck between the piston and the squish band . Lucky it was idling just outside my shop door , as I herd it start to “RATTLE” like crazy ,but it locked up before I got to it to shut it down . OH well ,them the brakes EH .

[@aaronpowell4885]

Sucks something so simple took that saw out☹ thanks for sharing👍🏻 Before this video, I never would've thought about inspecting the powder coating inside the case! Maby, I could see filling the bottom end with brake/carb cleaner and leaving it to soak causing that but not premix!

[@eriklong6390]

That is something I never looked at too closely yet. When I am in the cases of my Husqvarnas I never noticed anything that stuck out to me with the powder coating in there. But like I said, I have never really looked at the powder coating in the case too much. This is a great tid-bit of info for amateur builders like myself. Thanks Tinman.

[@tinmanssaws]

Ive seen cases looking thier paint but this is the first time I lost a saw to it.

[@Z-Bart]

I take it that's not normal for powder coating to be in that area of the saw?

[@edwingroening5087]

It is normal, but since it's so old and gotten hot so many times, eventually it starts to flake off.

[@martinburgess4814]

Glad to hear the wife and baby are doing great.Shame about the saw but it does happen i will remove all powder coating in future.All the best to you all.

[@Dolmar-Rick]

strange one Tin. I know dyno Joe did a test with porting shavings dumped in the bottom end and cylinder and it did less damage than that😂. wouldn't of though that powdercoat would of done that much damage but dunno. maybe the bits was to big that broke off didn't get blown out. where the alu fillings did🤷‍♂️

[@jesseflamme9366]

[@kennytheguitarfanatic054]

If you do bearings in the stihl 038 on the clutch side the seal is pressed in the bearing. So air can leak past the bearing. I would put green loctite or moto seal around the bearing. Take the clutch off see if you smell exhaust there .

[@Jason-si4mf]

I've built (4) Ms660 farmertec kits and I always remove the paint or powder coat or whatever it is from inside the cases. Ive noticed if you hit that coating with any sort of product that contains alcohol or acetone ie carb or brake cleaner it will soften and start flaking off. I'm not sure if the stihl coating is much better... Definitely not something you would want inside your engine. If you are rebuilding a saw or building a kit saw always clean the inside of the case down to bare metal. A thorough cleaning is always needed for the case halves of the farmertec kits as they always have a bunch of aluminum chips sitting in the bearings. I just got one of the new neo-tech 660's (FarmMac) and will most likely tear it completely down and inspect, bevel and smoothen ports and thoroughly clean everything.

I used brake kleen and carb cleaner,looks like I'm taking it off,great video I was just watching them all as I was taking it apart, good thing I seen this before reassembly. Do u think heating cases for the bearings could do this,maybe even more so for old engine. And I'm guessing if u have nick in the coating pre heating then u might lift more?

[@BillsGarageWorks]

Wow would’ve never even crossed my mind to check that! Do all saws have a powder coated crankcase? Glad the family is well and just keep doing you.

[@shakdidagalimal]

Why do they powdercoat the crankcase interior where the oil gas mixture is flowing around ? That seems ignorant. I bet they have other connected parts on the case and it would be an extra step to put a plastic blocker on it to keep the crankcase powdercoat free so they just skip doing that and load her up with paint !
