Question about Husqvarna "Chain Saw - 16" Bar, 3 Hp

Can't re-install side cover after chain replacement.

I can not get the side cover back on after changing the chain. The brake mechanism is specifically the problem. the band will not slide back over the flywheel.

    it might also be possible to partially put on the cover moving the guard slightly so the cover fits into the guard notch on the top inside of the cover and then (while holding the cover in that position) move the guard handle slowly to the off position, thus removing the tension on the band, and see if the cover pops in place. I have not tried that but I suspect it would work.

Either the cover was removed with the brake engaged, OR the brake was "tripped" while the cover was off the saw.
Clamp the cover in a vise being careful to stay on flat surfaces of the cover (use wooden blocks if needed) and pull the brake lever back to the "OFF" position. It's a strong spring so pull hard in the direction that would be towards the rear of the saw if the cover were installed.
Hope this helps.

Why won.t chain brake release


There is a "knee" mechanism in the side cover. It may have failed or is stuck. I would suggest pulling back on the chainbrake handle to almost break the handle, if it does not release pry the cover off of the saw. Then REPLACE the entire assembly side cover and chainbrake.

How to get the chain brake reset so ou can get the sidecover back on


If you have removed the sideplate on your chainsaw with the chain brake in the locked position, you will have a very hard time getting it back on without destroying the brake band. If you have done this try this solution. First remove the bar and chain fronm the saw, then start putting the side cover on, use one of the nuts on the front screw.As it comes in contact with the ratcheting part of the hand break make sure you push the chain brake handle forward while tightening the front nut I mentioned. when the nut is snug, pull the brake handle back to reset the brake, You will hear it click into place. then remove the side cover and re install the bar and chain. your good to go/

Install side cover on 455 rancher with chain break


Problem is you removed side cover with chain brake closed. You must open the chain brake to re-install the cover. You can do it with the handle. Put the side cover into position, put the handle into the fitting on the side cover. push the handle forward until you feel the "3" point connector engage. apply pressure to the handle and pull back until the side chain brake "Pops" open. Your Husqvarna dealer has a tool to open the chain brake if you are unable to get it open. Takes about 5 mins.

HUSQVARNA MODEL 435 CHAIN SAW.....BRAND NEW IN JUNE...NEVER USED....WITH BLADE, CHAIN, AND SIDE COVER (TENSIONER ASSY) REMOVED, IT RUNS FINE......WHEN CHAIN BAR , CHAIN, AND COVER ARE REINSTALLED AND...


There is a number of ways to re load the brake, you can either remove the clutch and sprocket, the brake will then go back onto the saw enabling you to use the hand guard on the saw to load the brake ( to remove the clutch, there are two cut a ways in the clutch centre designed to enter a flat screw driver into, then strike with a suitable hammer to remove, it is a left hand thread ) or you can remove the hand guard from the saw and use this as a tool to re load the brake, or you can clamp the cover in a vice ( be carefull not to damage the cover ) then use a strudy pair of pliers or grips in the three legged loading mechanism and turn it to load the brake.

I am trying to replace the chain on my saw. When I try to fit the clutch cover back on the there is a metal band that does not seem to want to fit properly over the wheel, causing the chain to not move...


Your chain brake mechanism is in the "locked" position...you will need to release it. Some husky's have the handle on the cover. If this is the case simply pull the handle towards what would be the rear of the saw and install the cover.
Other saws have the handle on the saw and some little cogs mesh with cogs in the side cover. In order to unlock this one I use two 1/4" x 2 1/2 inch or so bolts in a vise. They get clamped with the bolts protruding vertically above the vise jaws and are spaced so the the tips of the bolt will fit in between the cogs. Study the assembly and determine the direction of rotation required to release the brake. Place the side cover face down over the bolts with the bolt tips in between the cogs and rotate until the brake cams over and releases. be sure you know which direction to rotate the cover as a bit of force is required to get things moving.
Once the brake is released you should be good to go.
Take care.

Took off cover to put chain on and can't get the cover back on the brake band doesn't sit right


You need to release the brake mechanism in the cover so that the brake band will expand enough to pass over the clutch drum. You should have released the chain brake before removing the cover, but that doesn't help now. Use a wide heavy screwdriver to release the mechanism. Hope this helps!

Unable to release chain brake on Poulan 2150 2.1c.i. Unable to reassemble the chain brake cover.


You should have released the chain brake before removing the side cover. Try using a wide, heavy, flat-blade screwdriver to release the toggle mechanism for the brake in the outer cover which should expand the brake ring to allow it to go over the clutch drum. Hope this helps!

Clutch cover will not go back in place after changing chain.


The cover was probably removed with the chain brake set. Unfortunately, the brake must be reset in the cover with a wide blade screwdriver used in the coupling that connects with the handle mechanism. This will expand the brake band allowing it to go over the clutch drum. Good luck!

Trying to fit bar and chain on a new 445.can not replace clutch cover after following instructions closely.it seems brake is on. WOULD REALLY APPRECIATE HELP. THANKS.


You'll definitely have to unlock the chain brake to get the cover back on. You should be able to unlock it by pushing the chain brake handle forward, toward the bar and chain when mounted on the saw.

CHAINSAW BRAKE LOCKED ON HUSQVARNA 455 RANCHER HELP PLEASE?


I used applman08's solution. A few pointers:
0. This problem occurs when you take off the side cover while the brake is set. So after you fix this, don't do that again.
1. When removing the clutch, place the screwdriver in the notch next to where it says "off" and tilt the screwdriver down so that when you strike it you are applying a clockwise shock force that is almost horizontal (assuming your 455 is on its side).
2. DO NOT remove the spring! There is a plastic housing that basically holds the brake mechanism in place (secured by 4 screws). If you take that apart, and then take out the spring, you will be learning how the brake works and spending some time compressing that spring and getting it back in. You'll have to come up with something clever to get the spring in depending on tools available.
3. Going back to 1. - get that clutch off, put the side cover back on, getting that brake lever lined up with the very-difficult-to-grab three-toothed mechanism for engaging the spring. Tighten down the side cover, or hold it snug with one hand while you lever the brake handle with the other. You will hear a satisfying snap as the braking mechanism (with the spring I told you not to mess with) resets.
Note: You can probably reset the braking mechanism by manually turning that three toothed gizmo but it's really hard to grab and the brake handle fits it perfectly. The key is you've got to turn that about 60 degrees.
Good luck, this was an annoying problem.
