How to reassemble chain brake on an Echo CS-350T that jammed and was pulled apart by someone else?

From what I see you will need assemble thing leaving the main spring and brake cover off. Before attempting to put the main back in install a clutch drum inside the brake band. Then you slip on the main spring and pry the end on with a flat blade screw driver. Now install in the cover for the spring and brake. Reset the chain brake and remove the drum.

Now install the chain brake on the saw and test. Do not trip the chain brake without the clutch drum in place. If these are anything like the Husqvarna version after they get worn they will get where it is nearly impossible to reset.

How to remove the chain from a husqvarna 235e chainsaw?

Like this or pretty close.

  1. Cock brake while expanding chain brake binder by pulling brake handle towards left-hand (wrap-around) handle grip, hard, until it locks in place.

  2. Loosen 2 brake-asssembly-and- bar retaining nuts but do not remove yet.

  3. Unscrew (turn CCW) bar adjustment screw on front face of unit in order to shorten bar and slacken saw chain.

  4. Slip chain off bar over bar tip and towards inward side of bar.

  5. Remove two nuts loosened in step 2 and pull brake assembly and bar straight out and off bar mounting studs.

  6. While rotating clutch/brake-drum, maneuver saw chain off sprocket and around drum perimeter to remove from saw.

  7. Repeat/reverse steps 6 thru 1 in that order to reassemble.

I was cutting some wood when the chain on the blade stopped turning. i thought i'd done something wrong. when i got home i took the chain and blade off the machine and then reassembled the chainsaw. i...

If the saw was run with the brake on, or with the brake cover pushed on with the brake on, then there could be some damage to the drum, the clutch, or the pump drive gear that is normally driven by the drum, the lack of oil to the chain could be the same issue as the noise, remove the brake, clutch and drum, inspect all of these components for damage or blueing from heat, if you can pull the clutch shoes out with your hands then the spring requires replacement, check the needle bearing for the drum, if this is dry, then re grease it, check the oil pump drive gear for melting or damage.

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!

The chain brake on my UT10942D keeps shutting my saw down and will not disengage. The brake is constantly on. I have lubricated it with WD-40 and it didn't help.

Likely, the brake 'toggle' mechanism that keeps the handle in one of two positions is packed with sawdust/dirt that prevents full travel in the release position. Make notes of how the parts are fitted together, then dig out the spring and other components, clean everything, and reassemble. You may need to compress the coil spring with 'Channel Lock' pliers, and tap it into the recess. WD-40 is great lube, but not particularly effective on chain saws. Make sure the brake band is not deformed in any way. Hope this helps!

Husqvarna chainsaw 235e starts but the chain won't move. Maybe the brake is stuck??

Does the brake seem to 'snap-over' like it should? Pull it back to release position, and remove the drive cover. Check the entire brake for debris accumulation or bent/damaged brake band. Check the chain to see if it is being oiled. Remove the bar/chain and clean the entire assembly, particularly the small oil passages in the drive end of the bar. Start the engine and watch for oil oozing out of the small side port where the bar fits. If ok, reassemble the bar/chain. If no oil comes out, investigate the oil pump, lines, and filter/valve in the oil tank. Mount the side cover, but leave the fasteners finger tight. (The chain teeth cut toward you on the bottom run) Tighten the chain until the lower run comes up to the bar, but can still be turned by hand. Tighten the fasteners and recheck the tension. Trip the chain brake and make sure it locks the chain, then release it and make sure it turns freely. Check the chain oiling by running the bar tip at speed near some cardboard--it should leave a thin line of oil on the board. Hope this helps!

Starts but chain wont turn. and white smoke comes out the side where chain is. is it the clutch thats burn out?

Grasp the forward most upper handle (hand guard), move it forward, did it click? If no the brake is released. Pull it aft until the brake latches open (clicks), may require some grunt at rear extreme.
Remove the clutch cover, bar and chain. Start the saw, does it still smoke? Yes post back below, no reassemble your saw, ensure the brake is open. Start teh saw. Smoke? If yes post back below.

If you have more questions or need additional help please reply below and I will get back to you. Good Luck. HTH

I can't get the clutch cover back on my Husqvarna 235 e because the chain break is engaged. Spring is too tight to disengage it.

The chain brake is engaged when the brake handle is moved ensure it is actually the chain brake...with the clutch cover off and in your hand, pull the chain brake back...if it will not move, attempt to move it forward to see if it was not engaged...if it moves forward, it is now engaged...pull back to disengage it...a lot of times the problem is not the brake, but rather the bar adjuster....if the brake is not the problem,...loosen the bar adjuster and reassemble the unit...once assembled, then adjust the bar as per the user manual.

let me know what you find.
