McCulloch pm610 bar mount

[Ollie_M]

recently got hold of my dads old saw, a mcculloch 610, damn heavy and quite old now but sounds very different and it just has a special feel about it that new saws dont have. anyways i need a new bar for it and from my research it used d176 which is an 8mm slot. most bars now seem to be 8.2mm and have the oiler hole further forward but whilst looking at the oregon bar mount pdf i saw d009 which is a 9mm slots but has the oiler hole in the right place so my question is quite simple really, could i just put so 1mm spacers (8mm id, 9mm od) over the bar studs and do it that way or is there a better option?

The wall thickness would only be 1/2mm.I would be tempted to try it as is. If that moves too much for the oil hole alignment shape a piece of aluminium the same thickness as the bar to fit in the bar slot and then drill that and then cut it off half way through the holes.

 

I think I have one of those saws in the shed that I ought to try and start, it too has no bar.

Chainsaw Bar Adapter D176 8mm Echo Studs to 14mm A031

Use this adapter plate in order to fit 14mm Large Stihl type bars to the large Echo mounting studs which are 8mm.

 

Would this help?

you are most likely complete right, can always just hold the bar level ish before tightening bar nuts

Theres no practical difference between 8 and 8.2 spec surely? That's only two hairs of clearance which you'd probably have anyway.

yeah the clearance is less the issue its more that looking at the drawings of all the different bar mounts the oiler/tensioner hole always looks a bit far forward or backward. do have a 20 inch stihl bar from my 038 that i could try, can get adapter for 12 to 8mm aswell. now i've thought about it a bit.

Not sure we have any bars that fit but D276 is the mount and that bar in above pic is running 3/8 .050

 

But I'm not sure how available these bars are not to be had in the UK

If you wanted a fairly good used bar I’ve got one packed away in storage with the same pattern as the saw in the advert 

and there’s  a couple of other bars that aren’t 

shelf queens but usable
