    It happens sometimes, I recently changed both crank shaft end bearings on Stihl TS 410 stone saw that was only 6 months old. Your saw looks like a pro model, price up a new crank and bearings and do it yourself if it's cost affective over buying a new saw. Get that girl running again.

    Both big end and small ends of the connecting rod are blue. There is a bright blue band on the gudgeon pin (wrist pin, piston pin). This blue colouration is due to pronounced overheating and should never normally happen if all is right with the saw. Where you show the big end bearing locking up, you can see that there is a gap in the big end bearing cage on the right. The cage is breaking up. When looking from the right hand side and trying to turn the crank, I think that you can see that the left hand main bearing also has a broken bearing cage - the spacing of the balls does not seem to be regular.
    Both these cages are steel. On older, poorly maintained saws, especially if repeatedly thrashed with a blunt chain, you can get impacted fine sawdust pushed in past the lips of the left hand oil seal (behind the generator rotor). This gets through into the bearing and accellerates wear, causing the cage to fail or partially fail. Debris from this failure (bits of cage) gets through into the crank case and can into the big end and even (via the transfer ports) into the combustion chamber. I think there are signs of metallic debris being in the squish band around the outside of the piston top leaving little craters in this part of the piston crown. Throughout this process, air increasingly gets past the main bearing oil seal and the saw runs lean, exacerbating overheating. I have seen bearings embedded in the top of the piston and on one occasion (an MS261) a perfect half ball sitting on top of the piston, the ball from the bearing having been cracked in two. Popping the generator rotor off would show if the failure of this seal (and main bearing) is the root cause. Keeping chains sharp at all times prolongs saw life. Thanks for posting - nice vid.

  • @johnsonlong1272
    @johnsonlong1272 2 года назад

    Great details on your video and easy to understand you great job. We were seeing this kind of failure a lot with these newer strato engines basically you're opening up a butterfly introducing straight air which sends the crank to lean condition this requires Great oil not just good oil. And as you know it's very hard to get customers not to use Husqvarna or still mix oil in their power saws and both are a okay or good oil just not excellent and these type of Saw engines require excellent mix oil in order to get them to last. The customers I was able to convince to switch have not had bearing failures since. So I think it's a combination of a few things in your situation probably dull chain maybe eating some fines possibly mix oil. however we have all seen old saws that have ate fines for years and still no crank failure. It's really hard to tell but you did the right thing did a leak test first before tearing anything apart just to rule that out. On my end professional logger customers rarely run dull chain but they were still wiping out the crank bearings , rod and wristpin on OEM oil but only with the strato engines the standard engines were not going bad.

    Had the connecting rod bend on a BG 56c blower. This was 2 years old with looks to be light wear with disassembly. Connecting rod is flat plate without any rib/structure design. Contacted Stihl to inquire if rods go through any tempering/strengthen process and was told they do, and any chances of a defect was very light. They offered a comment; "lower is in a cage and cannot lock like a brush trimmer. Compression gets a "little" higher. Any comment would be appreciated.

      I would use grease myself. It is messy but it cleans up and keeps fines out of the engine. If a little gets sucked in it’s no big deal unlike silicone.

  • @Drottninggatan2017
    @Drottninggatan2017 9 месяцев назад

    I think you diagnosed this correctly. But it is probably not the crank's fault.
    The combination of a dull chain, fine sawdust all over, poor air filter and severely over stressing the engine for a long time would have built up heat. Check out the discouloration on the vrist pin. And perhaps that fresh air flushing system kept the piston cooler so that it did not seize up first.

  • @johnclarke6647
    @johnclarke6647 3 года назад

    He could have chunked a circlip from the piston, always on the intake side. Those nylon cage bearings are always a problem. It could have chunked a bearing and it got under the crank. I agree with you about getting “fines” into the engine on just about any saw. However Husqvarna XTorq engines are prone to bearing failures more than the old XP designs were, as are the new engines with Strato carbs.

    The fine saw dust could be from a dull chain. Which then would make the saw work harder for cuts. Definitely overheated. I’d buy a meteor crank/rod/piston kit for under $100 and it should work like new again.

    Good video ! What I think happened. Usually big end rod bearings turn blue and fail because the high jet on the carb is turned in and let the engine over rev. Or they could have been cutting soft rotten wood judging by the fine dust and the engine RPMS would be at max for long periods of time. But a dull chain could burn up an engine but usually the clutch turns blue and melt the plastic bearing cages.

I have literally installed short blocks under warranty and units come back in 6 months with same main bearing failures it’s ridiculous.

    As filthy as that saw was it is no wonder that something failed. Saw dust and oil hold heat, which is why you need to keep a saw as clean as possible. I blow out my saw after each use and give them a deep cleaning once a year. I see saws all the time that need to apply for a crop allotment from USDA because they are so filthy. I won’t say you can eat off my saws but pretty close.
