Husqvarna 445 gas powered chain saw blade cover stuck

The blade cover won't lift off after taking off the cover nut. it looks like the end of the tension band is stuck in and I can't seem to get leverage to "pull the end out of the plastic"...any ideas?

    Same problem tonight...I got the cover off with the tensioner finally but now when replacing the cover I cant get the band to go over the drum(gear). Is the whole gear supposed to come off with the cover?

    Found another way. Put the drum cover in a vise with the end closest to the three-spoke brake hub clamped and the hub facing upward. Turn the largest spoke clockwise and downward into the locked position using a needle nose or suitable pair of pliers. The lock mechanism is hard to turn but will give and snap into place with enough torque. Then replace the cover,

Make sure the chain break is disengaged (fully up). When the chain break is down there is a stainless steel band in the cover that grips the clutch and the two parts will not easily come apart.

Chain wont tighten up

Loosen the two nuts on the right side cover of the saw (1/2 inch socket) turn them out 2 turns. Use a flat blade screwdriver on the screw at the right side front of the housing (near where the bar comes out of the saw). Turn the screw right until the chain can only be pulled up 1/8 of an inch at the top center of the bar. tighten the two 1/2 inch nuts. The two nuts clamp the bar so it won't move. If the chain tensioner still won't work, remove the right side housing by removing the two 1/2 inch nuts and look at the tensioner assembly and how it fits into the chain bar. The problem will be obvious. If you need to replace the tensioner assembly, a new one can be ordered through

Loosen or tighten chain on a 445 Husqurna Rancher chain saw

If this is the tooless system, flip open the wing on the bar cover securing nut, slacken off one turn, now use the knurled wheel in the cove to slacken, or tighten the chain, if it has two 13mm bar nuts, slacken them off one turn each, then use a flat blade screw driver through the side cover, betwwen the bar nuts to adjust the chain, the screw is quite small so clean away the saw dust to locate it.

Tryed to put on a chain cant get it back togather right

Completely loosen the chain tensioner. When looking at the saw from the sprocket side(bar to the right) the chain WILL travel clockwise. Fit the chain on the bar.(ensure that the chain travels in collation with the sprocket at the end of the bar if equipped). When looking at the saw from the sprocket side(bar to the right) the chain WILL travel clockwise. With the chain still in the bar, fit the 5 or so links in the sprocket on the powerhead, engage the bar with the bar nuts, then lastly engage the chain in the tensioner. Place the sprocket cover and nuts. Tighten nuts then loosen about .5 turn. Adjust chain tensioner. Retighten nuts. See that tightening the nuts made your chain tighter, loosen nuts readjust chain, tighten nuts. With gloves on and the chain brake disengaged please ensure the chain travels around the bar. Put on your chaps and start cutting.

Sounds like your chain is to tight.Take the cover that is at right side of the saw motor off and loosen the two nuts a bit and look for a tension screw behind the bar and back it off,if the bar won't move loosen the two nuts that hold the bar on the saw.With the saw siting like you use it pull down on chain and get about 1/8 of an inch between the bar and chain.(use gloves)If the bar is blue by the chain groove You will need a new bar.Blue means the bar has over heated and lost its temper.The blue metal is brittle in other words.You should all so check the drive sprocket for wear.

If this is not the solution that you are looking for please re post because when we pick a question to answer FixYa takes it out of the questions. Thank you for choosing and good luck.

Changing a new chain?

Start by making sure the chainbrake is off, by pulling the hand guard fully to the top handle, now remove the side cover fixing nuts, or single nut if it has tooless chain adjustment, take away the side cover, wind the chain adjuster fully back, if it is in the cover wind the knurled wheel back, now lift the old chain off the bar and loop it over the sprocket and away, loop the new chain over the sprocket and lay it into the guide bar rail, with the cutting edge on the top of the bar facing away from the saw ( the chain rotates clockwise as you look at it ), re fit the side cover, make sure the adjuster pawl aligns with the hole in the guide bar, re fit the nuts finger tight, adjust the chain so as it touches all the way around the bar, now with a gloved hand pull the chain around the bar manually, this will ensure it is correctly in the sprocket, re adjust the chain if required ( it should not sag at the bottom of the guide bar ) now lift the bar nose and fully tighten the bar nuts.
After ten minutes or so cutting re tention the chain.

Model 445 chainsaw. Was cutting all day and no problem. Good gasoline, Husqvarna 2 cycle oil. All of a sudden started racing like the carb was stuck full open even when throttle trigger released. Then...

Engine speeding up on idle is normally due to an air leak, check the carb securing screws are tight, if you have a leaking crank seal it will be a shop repair.

Fly wheel seemds locked up on Husqvarna 445

the flywheel does not have a brake,the clutch side has the break.if you have the chain side cover off the brake is no longer on the clutch drum.the fly wheel is on the oppiset side (starter rewind).take the starter rewind off and see if the motor will turn.if hte motor turns the problem is in the clutch side.if it doesn't the problem is in the flywheel side.the ignition coil has been known to loosen up.the screws streitch out from heat.check the air gap between the flywheel magnets and the ignition coil.should be .10 to .12 inches.if problem is on clutch side check to make sure that the springs are on between the clutch discs.they have been known to break and that does not let the chain spin on bar.any questions get me an e mail
