New Chain Sticking

[Justjames1961]

I presume that's the info off the bar. What did it say on the chain's box?

Then someone has put the wrong chain in the right box!

What numbers are stamped on the chain?

 

There should be 2 on the cutter and 6 on the drivelink.

Take the new chain off and check that all the links move freely.

Unlikely, but...

 

I've had this when the bar is getting pinched very slightly when the clutch cover is tightened. Possibly when something is stuck behind the plate that covers the oiler channel, or when there's slightly too much paint applied to the bar around the rails, or if there's any warping in the clutch cover.

 

Basically if the clutch cover/clamping area isn't true or flat.

 

Can be tested by loosening the stud nuts slightly and seeing if the chain runs, then tightening and seeing if it jams. When hot.

 

Fixable by cleaning and/or light flat-filing of the bar side/end.

Hi

 

Just for reference heres a useful link

 

Chain | bar | sprocket identification

Take the bar off, put the chain over the nose sprocket and pull it round slowly, is it smooth without riding up and off it.

 

Do the same with the clutch sprocket, can you pull the chain round the sprocket without it riding up and off the gear.

 

Hang the old and new chain off your finger, line up the cutters and make sure they line up over a length of 4-5 cutters - if not, you have the wrong pitch chain.

 

It can't be that hard to sort this one:confused1:

Is the saw running with a spur sprocket ? if so has it got large grooves worn into it ?

[biggarlogs]

could the chain be joined with the wrong tie strap?and if so is the chain binding at the join?or else there could be a burr formed when chain was broken?

[agg221]

If the bar is 0.063" then the chain is not too wide a gauge, since this is the widest gauge bar.

 

Do you have an old chain, and does it run fine? If so it must be an issue with the new chain.

 

If you don't, and you have the same problem with two bars on the same saw it points to an issue at the bar mount/sprocket end.
