    Does sprocket size noticeably affect torque?

    I was talking about the groundies and other help not the guy who forked out the money for the saws to begin with .Around here the only people other than the tree service owners who furnish their own saws are contract climbers . I have no idea about the loggers because they are far and few...

    Does sprocket size noticeably affect torque?

    Trust me some of the pros are hard on them too .The most trashed out saws I have worked on have came from tree services .

    Does sprocket size noticeably affect torque?

    Well you probabley don't beat the piss out of them like some of them I repair .I had one,some model of Stihl they ran with no drum bearing .Fried the plastic around the drum and broke two out of three clutch shoes .I had a tough time getting the drum off .

    Does sprocket size noticeably affect torque?

    Conversely I've pulled drums were the bearing cage was gone vanished .Well you know the rollers bunch up and the drum could run eccentric or wobbley which would be hard on the drum ,clutch shoes and crankshaft ,bearings ,seals .Bad enough they would break the clutch shoes. Now that's cool a...

    Does sprocket size noticeably affect torque?

    Not really .However any bearing with no seals will need attention if it's lubricated .Not a big deal just something you need to do . I've pulled greased bearings from drums of old saws that evidently never got checked and the rollers were froze solid .A little spritz with some WD -40 they...

    Does sprocket size noticeably affect torque?

    It would not apply to a chainsaw application .However when they lubricate a sealed bearing for a precision spindle used in high speed CNC machinery they first remove the seals then they power flush all the grease out of it .Then they regrease it and blow all the excess out with compressed air...

    Does sprocket size noticeably affect torque?

    It's not a bad idea but there are two trains of thought on that .One being it attracts dust .Personally I blow them off and squirt a little oil on them in the event I pull a drum off . Now as I recall it that 034/036 that Cut ended up with had a funky bearing which I replaced .What I can't...

    Does sprocket size noticeably affect torque?

    I ran one of Deans master pieces at a GTG and it was a little torquer .Fact the one I built up although stock did well for it's size but I didn't have it long enough to delve into any enhancements on it . Fact Tom used it for a couple days or maybe a week after he encountered a bunch of...

    Does sprocket size noticeably affect torque?

    You have to ask yourself a question though .With the 036 top it's still only a tad over 60 cc's .Souped or not an 8 tooth might really put the dogs to it . Then again if you played with the chain and left the rakers say about 22 thou and kept the speed up it might handle it .You'll never know...

    Does sprocket size noticeably affect torque?

    Okay Jay here's what I gleened from IPLs .The 034 and 036 list different clutch shoes but the same number of clutch drum .The 036 and the 044 list the exact same number of clutch shoe so that tells me the clutchs are the same diameter . The drum bearing on the 034/036 is a metric 10x13x 10 .The...

    Does sprocket size noticeably affect torque?

    Well that's the problem I have too ,no specific knowledge .Often times I sort through buckets of parts and get a saw running from bits and pieces but have no idea what they came from except for the fact they are Stihl parts .

    Does sprocket size noticeably affect torque?

    I can't remember how I did it but if I'm not mistaken the 028 Super in my shed has a normal sized spline drive on it .It seems to me the drum came off of another Stihl and I had to use a different bearing .However on the 034/036 it would have to be the one with the slot in it to drive the oil...

    Does sprocket size noticeably affect torque?

    If that's the same as an 024 the number is 1121 007 1002--.325 8 pin.For that size saw it's also available in 3/8" pico or lo pro depending on how it's listed .

    Does sprocket size noticeably affect torque?

    FWIW all my large old saws came from the factory with 8 pin .404 sprockets .Keep in mind they were made in the days of slower running but high torque engines and were primarily used on west coast old growth .The 084 also runs an 8 tooth .404 and does nicely with it on a 42" bar . I most...
