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 do I re-set chain brake on husqvarna 36

Quickest way to load it is to remove the clutch and sprocket, the brake will then go back onto the saw and enable you to pull the hand guard back to load it, you can clamp it in a vice and pull the hand guard back however it is very easy to damage the cover like this.

How do I get the brake band ,located inside the chain cover, assembled back onto the chain saw. clutch assembly. The band brake diameter seems too small to fit around the clutch housing.

You need to load the brake, clamp it in a vice, be carefull not to damage the cover, if the hand gaurd is connected to the brake pull it fully back until the locks off, this may take a fair amount of force as it is compressing a large spring, if the hand guard is on the machine, remove it and use this as a tool to load the brake, the only other way is to remoce the clutch and sprocket, now refit the brake onto the saw, now pull the hand guard fully back to load the brake.

Husky mod. 51chainsaw. how do i re-assemble chain brake lever? i do not know how to reset the handle to allow the internal clutch locking spring to slip over the clutch

To re assemble the hand guard back onto the brake cover, place the hand guard as best you can onto the side cover, now use a conical punch to push throught the hand guard and cover, now useing the punch as a pivot pull the hand guard fully back until the brake loads, once loaded remove the puch, the hand guard should now easily align back onto the cover, insert the two puvot collers and re fit the allen screw.

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!

Chain is locked and wont release

Remove the drive cover plate, then inspect the internals of the brake assembly. Either the brake band is damaged or possibly full of debris that prevents release of the brake. Does the brake lever actuate when off of the saw? Clean the entire assembly with compressed air and check the brake 'toggle' action. Look for damaged components. The brake mechanism must be released to reinstall the cover. Clean and check the drive end oil passages for any plugging. When the cover is installed with fasteners finger tight, adjust the chain until it comes up to the lower run of the bar, but not so tight that it can't be pulled by hand. Tighten the nuts and recheck tension. Check for proper oiling by holding the bar tip near a piece of cardboard and running at speed for a few moments--it should throw off a light line of oil onto the board. Hope this helps!

How to replace chain on McCulloch chain saw? How do you get the brake over the drive wheel to reaffix the outer cover and brake release?

The chain brake is engaged. support the cover firmly (as it will require a lot of pressure to pull the handle) and pull back towards the operator. When it is re-set, it will then fit properly to be assembled to the saw.

How do I reinstall the chain brake on my Poulan Wild Thing??

Find your model number add a LE suffix (i.e. if 2375 make it 2375LE) the "Handle, Chassis, and Bar Assembly" shows what detail is available. If not enough detail tell Poulan! Maybe it will improve for the next guy. If not happy with Poulan answer tell Husqvarna (parent company).
An entire new clutch cover (2375LE Type 2) item 36 pn545139903 is $19.43.
Sorry to not be more helpful but this is all we can do. HTH

I have a poulan 18" chain saw. The safety band that goes around the clutch came off. Need info on how to put it back on

You don't list your model; There are probably over 100 to choose from. Find your model here:
Open the IPL. find the "Handle,Chasis and Bar Assembly" or similar page. That is the only drawing showing the chain brake parts. If you aren't able to repair it using that your options are to find your friendly neighborhood chainsaw shop or a new saw. HTH

I was sawing and the chain stupped turning. The brake is off and it will rev.

You should check the clutch assembly to see if the chain jumped off the clutch teeth or if the keyway that locks the clutch onto the motor drive shaft, has either broke or fallen out, etc.

You might also want to engage the brake back and forth a few times to make sure it is fully off, as sometimes they get partially engaged and stop the chain from moving until fully reset.

With a model number, more detailed info might be able to help assist you resolve the problem, but I've provided the basics to check out.

Hope you find this info Very Helpful - Best regards!
