    Hi folks,
    I'm interested in the differences between the Chinese zenoah g5200 clones in the 45-52-58-62cc range. My understanding was that to upgrade lets say a 52cc saw to a 58cc, one would just have to switch piston and cylinder. In one thread, I read that replacing the crankshaft was also required, perhaps due to port timing, but I am not convinced of that. Replacement cranks are most often marked "fits 45-52-58cc", so I don't really see a difference between a 52cc and 58cc crank, is there one? Does this also apply to 52->62cc conversions (no crank replacement necessary, just top end?). If anyone is the wiser as to explain why a different crank would be needed, I'd like to hear it, as I understand only the cylinder bore width changes, not the stroke? Would be grateful for any ideas!

    If I am remembering right the 45 52 58 all have the same stroke with a different cylinder and piston. I have not heard about a crank change. Most of the saws advertised as 62cc are really 58 or 52cc saws. True 62cc saws have a longer stroke, most if not all are based on a different saw.

    Guys who have bought different sizes say the 45 revs the best and the others are slower. The carbs for these saws are sized for 45cc and do not flow enough for the bigger saws.

    Again this is all I can recall from my readings I have not owned any of these models

    Couldn't talk you into adding a few dollars and getting a lot better saw in every way could I.

    Nobody take this personally. I realize that "clone" is a convenient word to use to describe these saws but "copy" is far more accurate.
    If I were to paint a copy of The Mona Lisa, it'd clearly be a copy...and a really bad copy at that, so I've started a one-man campaign to replace "clone" with "copy". Are you with me brothers and sisters? ;)

    The point of using the right word is that "clone" implies conformity and it would be foolish to presume that any 2 (or any 22) of the Chinese factories making these things are using the same part, the same dimensions, the same specifications, the same materials, or the same screw heads, as any of the others.

    To the best of my knowledge, 45cc, 52cc, 58cc and 62cc labelled saws, all use the same crankcase and therefore the same stroke, which leads me to suspect that a swept volume of 62cc is more aspirational than actual. Reinforcing this suspicion is the fact that brands such as Huztl/Farmertec, who openly advertise the capacity of their base model Husky 372 copy as 65cc, don't offer a 62cc version of their "Joncutter" (weird nameo_O) Zenoah G5200 copies, the largest being 58.

    45, 52 & 58 models all have outboard clutches. (Maybe that's what 'Dph 1256' actually meant.)

    Thank you for clearing that up I was under the impression that the 45 52 and 58 had inboard clutches.

    Someone said that the 62cc model was based on the Zenoah g621.

    The G6200 & G621 are a different "family" to the G5200 and do have the clutch inboard.

    I edited my first post to remove misleading information.

    I haven't seen an ad for a 62cc copy that looks like a G621 but I'll keep my eyes open.

    I think that's what they are talking about. I bought one 6 or 7 years ago for $80 off ebay and the starter was broke and when I asked for a replacement starter they sent a whole new saw so I ended up with 2. One lasted about 5 years of loaning out and I still have the other. They run like a 40-45cc saw, at least the two I got did. You can still get them for $80 in the US Screenshot 2019-08-14 at 2.36.35 PM.png .

    One youtube review of a 52cc said that the box and the saw side label said 52cc but on the bottom of the saw it was marked as 45cc. A week ago I emailed a USA seller of the same exact saw that Ronie posted and the seller assured me it is a 52cc saw.

    I ordered that same saw two weeks ago for $50 shipped. The sellers rating when I purchased the saw was 96% with many items sold. Since then, the sellers rating took a dive to 54% and he made all reviews private. The seller did ship an item and it cleared US customs two days ago. It will be interesting to see what is inside the box I receive. lol Gotta love eBay money back guarantee.

    Good Luck!! lol

    Honestly I’m going to be using it as a project saw. I’ll make sure it runs, probably put one tank through it and then it’s gettibg ripped apart to be tinkered with.
    Either way it has to be better than the poulan 3314 they sell up here.

    Poulan 3314 200$ cdn
    Chinese 52cc 160$ cdn

    The 52 comes with a magnesium housing so right there that’s better. But we will see when it arrives

    Colour had no merit for the purchase, it was the ONLY Chinese clone for that price avail on amazon Canada.

    On hutzl’s website they are cheap enough in USD but when you goto the shipping calculator they want 300-400$USD .
    Lmao for that price I’ll just pay extra for the real thing

    Thanks for all the great info guys. What really amazes me that by volume, probably half the world (especially the developing countries where cost is the foremost concern) uses ONE same model of chain saw. 7 billion people, millions of engineers and designers, and a huge chunk of the device we call 'chainsaw' was designed by some Japanese dude in the 70s and somewhere in magictown Shenzhen there are a few factories churning out a MAJOR part of the world's chainsaw supply. Just fricken amazing, why reinvent the wheel when the old design works good? Recently I have been quite amazed by how globalization, and Chinese manufacturing have become so dominant, that whatever DIY store you go to, US, Canada, Europe, Asia, you find all the same tools, same design and probably often same tool markings. Things like generators, compressors, brush cutters, saws... all Honda, Zenoah etc. clones, the ubiquitous Harbor Freight Trailgator "ET950" generator, known around the world, from multimillion cities to shanties on some far flung island of Palau, all Yamaha ET500 clones from 1979! And don't get me started on all the little 6.5HP Honda GX200. On one hand, it's so amazing how unique and diverse the world is, on the other hand, crazy how efficient and streamlined some stuff has become. Some days I believe a flood in one Chinese industrial zone would stop production on all the worlds cheap *insert powertool* supply, overnight. All these wondrous things, all presumably stemming from only a few dinky warehouses in China. Gets you thinking how bad we have become in manufacturing stuff ourselves though... /philosophical boondoggle finished

    I purchased a italian made bender Castor chainsaw, I’d like to add a Chinese made saw too but it better run perfect right out of the box.


    Look at the Arab gunsmiths who are camped out in the desert and make guns they even forge parts.

    Remember a time when the stuff from Japan wasn’t quality. Now look at their cars and electronics, I think of China the same way just wait till there quality improves,

    I worked in a cabinet shop in the old days, one woodworker was from the old country. They lived and worked with the senior woodworker to learn the trade.
    I wish I took pictures of the workmanship these guys did, with a wooden hammer and a wood chisel. Carving u turns in monster sized stair handrails for the Lipton tea company family home in Southport, ct. we used a giant shaper for the long sections, the curves and u turns were done by hand,

    My point is we have lost these tradesmen.

    The only answer to questions about the knockoffs is to get some and go from there. In terms of what parts are interchangeable, who knows? Best bet is to buy the saw from the same people you are planning on getting the parts.

    A new $80.00 delivered to your door 52cc saw should be expected to be just that, the last time I could get a new saw for $80.00 it was a 32cc Mcculloch from Home Depot. The knockoff 52cc saws I am familiar with are far better saws than those or the $100.00 Poulans of the same era.
