By flwheel i am guessing you are talking about the clutch, there is a special tool with two pins on that fits into the two cut a ways in the clutch centre, it then has a 19,, nut on the outside so as to jar it off against compression with a 19mm socket and impact gun, if this model has an inboard chain brake make sure the brake is off by pulling the hand guard fully back to the top handle.Tool part no. 530031112

My 340 (,98) saw blade was dry while cutting, I shut down. I believe it is the oiler, idea's? js

If the chain is dry it has stopped oiling, remove the bar and clean out the bar groove and oil hole in the bar, there is a filter in the oil tank, to acess this you need to turn the saw upside down, look between the crankcase and fuel tank ( guide bar side ) you will see a cross point self tapping screw, this is retaining a plastic pull out filter, once the screw is out you may need to grab the filter with a pair of long nose pliers to remove it. There is also a drive gear driven by the back of the sprocket, this will require removal of the clutch to acess the gear. To remove the clutch put the screw driver side of the combi spanner supplird with the saw into one of the cut-a-ways in the clutch spider and jar the clutch off usibg a hammer to strike the other end of the combi tool, the clutch is just spun onto the crank, left hand thread.
Good luck

Need to know how to change chain on a 14inch McCulloch Eager ****** gas chain saw

Turn the chain adjusting screw CCW a turn or two, release the chain brake, and remove the large nut on the right side cover. The bar and chain will come off after removing the cover. (note: a 16" bar and chain will fit the saw which makes it a little more useful if cutting trees) Be sure to clean the small oil passages in the drive end of the bar that run from the large holes out to the chain groove on each edge. It is common to flip the bar over to equalize chain groove wear. Also, if the outer corners of the bar edges have wear that causes the metal to flare outward, use a file to cut off those sharp edges (at about 45 degrees) so that it doesn't project beyond the bar's flat surfaces. This will help prevent a cut from wandering off to one side. Re-assemble in reverse order after cleaning the engine and cover. You may have to turn the chain adjust screw some more to compensate for the old chain which will stretch with use. Make sure the adjustment 'tang' falls into one of the large holes in the bar before tightening the cover nut down. Hope this helps!

Can start the saw but when beginning the cut the saw power declines and will not cut. Please advise

The chain may need proper sharpening--it should not have to be forced to cut quickly. Make sure the bar and chain are being oiled enough. If the engine speed does not decline much, but the chain speed slows down, the clutch assembly may be full of oil (remove the cover and wash out the clutch with spray carburetor cleaner). Make sure the chain is properly tensioned--it should be tight to the bar, but able to be moved fairly easily by hand. Check the fuel filter and air cleaner for plugging. Make sure the fuel lines are in good condition. Hope some of this helps!

Chain saw starts and runs chain is moving at high speed but when placed against log it slows to a stop and does not cut, what should I do

Remove the clutch cover, bar, and chain. Wash out the interior of the clutch with spray carburetor cleaner to get rid of oil build-up. Reinstall the bar, chain, and cover after cleaning the bar drive-end small oil passages that run out to the chain groove. Adjust the chain up to the bar, but not so tight that you can't move the chain by hand. Hope this helps!

I have a Poulan P2316 chain saw. The chain got stuck in a tree. After freeing it, the clutch appears to be locked up. The chain moves freely on the bar when I remove it from the saw. Thanks Alan

Make sure the chain brake isn't set. When you turn the clutch outer drum, does it try to turn the engine as well? If so, try oiling the bearing that allows the outer drum to turn over the inner section, and work the oil into the bearing. If no help, you will need to replace the clutch. It is held to the shaft with left-hand-threads and usually requires a special tool to remove it, plus the upper cylinder needs to be stuffed with starter cord so that the piston cannot rise much above the upper part of the exhaust port while trying to remove the clutch. Don't try to remove it with an impact wrench as that will shear the flywheel key. Hope this helps!

Cannot move the chain by hand after the bar has been tightened.

First be sure the chain is on going in the right direction. When looking at the bottom of the bar the sharp tooth should be going towards the motor. When you put chain back on are the chain teeth properly engaged in the sprocket on the motor. Remove the cover again, check that teeth are in sprocket. Make sure pin from adjuster screw is engaged in the hole in the bar. Before you tighten the cover bolts, make sure chain will turn by hand. If not adjust the adjusting screw. Once adjusted, tighten cover bolts. Check again after tightening bar.

Chain won't rotate

Assuming that you have a fueled engine saw instead of an electric type, remove the drive cover after releasing the chain brake and backing off CCW the chain adjuster screw. Remove the bar/chain and clean the assortment of parts including the small oil passages that are in the drive end of the bar. Wash out the interior of the clutch assembly with spray carburetor cleaner and let dry. Start the engine without the bar/chain and watch for oil oozing out of a small port in the side of the engine case. If nothing, check the oil pump, lines, and valve/filter within the oil tank. If ok, re-assemble the bar, then the chain over the sprocket and out over the bar. Extend the bar out to tighten the chain, and fit the cover to the saw. Tighten the fasteners finger tight, then adjust the chain up to the lower bar edge (the teeth cut toward you on the bottom run) but not so tight that you can't turn the chain by hand. Tighten the fasteners and recheck chain tension. Check chain oiling by running the bar tip at speed near a piece of cardboard for a few moments--it should throw off a thin line of oil onto the board. Hope this helps!

Husqvarna 350 oil not getting to chain

Take the bar and chain from the saw. Clean the two small ports that run from the large oil holes at the drive end of the bar out to the chain groove on each side. Clean the entire chain groove. Start the engine with these parts removed--oil should ooze out from the side port in the engine case with the engine running at med speed. If it doesn't, then there is trouble near the pump inside the case. When everything is back together, run the saw at full speed with the bar tip near a piece of cardboard--it should throw off a thin line of oil onto the cardboard after a few moments of running. Hope this helps!

When i try to do a horizontal cut my saw seems to bite in for a start, but then just runs free in the tree not taking a bite or drawing the saw in, this has also happened with 45% cuts, is this my own...

Sawing with a chainsaw is mostly 2 part, a sharp chain and good technique.

If your bar is straight, your chain is razor sharp and the oil reservoir full then it boils down to technique.

You cannot run a chainsaw through horizontally on a big tree, what will happen is half the time the tree's weight will begin to collapse upon the bar and pinch it in the tree and you will not be able to saw any further.

You will notice that when felling a tree the vertical cuts are always problem free because gravity pulls the off-cut away from the saw. With horizontal cuts fire your blade in at an angle, and in cut in the direction the tree (or whatever) is likly to fall. As you cut rock your blade to help it bite into the wood and resist jamming. If your chain jams do not keep on the gas for you will burn out the clutch.

For an awkard cut instead of feeding it right through cut towards the middle to create a notch, then cut from the other side, the weight of the tree will fall on the cut portion leaving your blade free to slice through.

Just think logically and make sure that the blade can feed through without getting pinched, this is well represented if you get a log and support both sides then cut vertically in the centre; it will get pinched imeediatly. Now cut from the underside and it will fly right through.

This is difficult to describe but plan your cuts and test it out.
