Help finding correct replacement chain

[Bob Wootton]

Hoping I might get a helpful reply and not get lynched here!

 

I have a petrol garden multi-tool with a chainsaw attachment for light pruning jobs.  I believe it’s a rebranded Hyundai HYMT5200 MAX.  The chain has seen better days and needs replacing.

 

I approached the company that supplied the machine and whose label is on it to send me a suitable replacement, but they have proved disappointing.  (Their phone lines are closed for Covid and play a prerecorded message from March; they seldom respond to emails and over some six weeks have so far sent me three chains, none of which fits).

 

I have been able to measure the chain but not determine its manufacturer as there are no ID marks on the drive links.

 

I now understand that a chain’s length is determined by the number of drive links it contains, implying that all links are a standard size.

 

The first replacement the original supplier sent me also has the correct 39 links, but is too short to fit over the guide bar and drive sprocket at maximum relaxation, however much I try to coax it.  (The other subsequent ones are both far too long).

 

If links are a standard size, then it follows that any 39 link chain anybody might send me is also going to be slightly too short?

 

Which makes me think that I may have to modify the tensioning mechanism itself, in which case the first replacement chain might fit on after all.  I can apply rather more tension that I actually need and may be able to do that, but it would be fiddly and irreversible.  Then again, the machine was not expensive and I think is just out of warranty anyway.

 

Any experts out there who can shed any light on my predicament?  Thanks.

links are not a standard size . Different pitch chains have different size components . different widths ( gauge )

Pole saw i would think its either 3/8 picco or 1/4 picco ? is there nothing written or stamped on the bar that gives you bar length, rail width etc.

Strikes me the easiest way would be for you to put the chain in a jiffy bag and send it to RobD, he could send it back with two replacements and a file kit for keeping them sharp.

Just thinking out loud, would be for Rob to make that offer obviously.

Are there any numbers stamped on the drive links?

It should state on the bar what chain it takes.
