404 Chain Presets Joining links

[bolla]

Hi I have some made up 404 chains that are odd lengths mainly 137 drive links.

 

Does any one know why stihl would have made chains with 137 drive links is it possible they would fit a 47" bar even though a 148 drive link chain is recommend, is it possible the 137 chain is going to stretch as soon as it spins around a couple of times and then be suitable for the 47" bar

 

Is it possible to add another drive link or best to shorten the chain.

I have not been able to find any presets for stihl 404 chain does any one know if they are still avaible from stihl.

Thanks

Best to add a drive link - don't try - I have some tie straps you can have with some spare lengths if you PM your address over.

Several possible reasons spring to mind: someone can't count, someone measured around the bar and didn't realise that you need the slight play to get the chain over the sprocket, or it could be that they were made up for an older model with an outboard clutch, which can change the location of the bar mount relative to the axis of the sprocket (on a long bar, a chain which runs at midpoint on the tensioner on an 070 is too slack to run on an 076 for example).

 

Either way, Rob has the solution!

Hi Rob

Thanks for that

I need to order some bits from you in about a week. I will add a note about the tie straps with my order.

Thanks
