Question about Husqvarna 450 e-series 18" Chain Saw

Open Question

Bought 450e in March 2009. Not used it much but doing some maintenance. Having removed the chain tensioner wheel, the chain and bar are loose, but I can't get the clutch cover off: the brake seems to be part of it and the spur sprocket welded on the inside of the clutch/brake won't come out of the machine. If I were to wrench it off, it would damage the brake band which seems to be holding the cover to the outer rim of the clutch/brake. What to do?

SOURCE: chain brake band will not release to replace the clutch cover

Hi there
Sometimes that's not an easy job . I work for a Husqvarna dealer and I have that problem frequently . First try to get the clutch cover on place (do not use the bolts) and push in @ the top part of the clutch cover , then try to move the clutch lever backwards to release the band (better if done with two people) . If that does not work the only way is remove the clutch lever with the 2 bolts on each side and put the lever on the clutch cover (top metal piece that looks like a clover)to release the band (again with 2 people one holds the clutch cover and the other one the lever pulling the lever backwards) .
Hope this help

Use a heavy, wide blade, square-shanked screwdriver to turn the coupling in the cover to 'release'. You may need an open end wrench on the screwdriver shaft to get enough torque to turn the brake coupling. Hope this helps!

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.

Hi, the chain brake has most likely been activated while removing the cover. Place the cover in a vise where the bar nuts tighten up to and pull the chain brake lever backwards towards where the handle bar would be. It should click back and stay back. Hope this helps, regards Phil.

I can't get a replacement chain back on the bar on


The 450E is a tooless system, make sure the brake is off by pulling the handgurd fully back to the top handle, flip up the lever on the big grey fixing nut, undo counter clockwise, wind the grey knurled adjuster wheel facing out of the cover fully back, remove the chainbrake side cover, push the guide bar fully back toward the sprocket, you now have enough rome to replace the chain onto the guide bar rails, now re fit the side cover, make sure the adjuster pawl in the cove aligns with the adjuster hole in the bar, re fit the big fixing nut finger tight, wind the adjuster wheel down to re tention the chain, when the chain is snug all the way around the bar tighten the nut fully.

How to check for proper chain tension husqvana 450e


Hi,

You should be able to move the chain with your hands, but not too easily. Please wear gloves when doing this. Also, if you pull the chain away from the bar at the middle of the bar, there should be no more than 1/8" between the bar and chain.

Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

Chain keeps coming off Poulan 2150 woodsman gas chainsaw> Common causes?


The most likely cause is a loose chain.
Chain Adjustment
  1. Make sure the chain brake is off (gloves will protest your fingers).
  2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They do not need these really loose - finger tight will do.
  3. Ease the tension adjustment until the chain is obviously loose.
  4. Using one hand, hold the nose of the bar up.
  5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
  6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.

The chain keeps coming off, even after using the wheel to tighten it.


Model and serial numbers would be helpful. You can respond even though the thread is closed below the advertisements.

Remove the clutch cover, bar, and chain. Inspect the drive sprocket is it deeply gouged or perhaps worn through? That can cause this problem. The most likely cause of this problem is incorrect chain installation or a badly burred chain.

The chain will have burrs on the drive links of the chain and may not fit the groove in your bar. If true use a flat file on the side of the drive links and remove all burrs.

Your saw is equipped with a "Chain Catcher". That is what causes the burrs. Without the catcher it would have been your leg. Were you wearing chaps? HTH

The inside part of the chain are called drive links. I think when the chains came off the first time (loose chain?) some of these links were slightly deformed (burred). Take a flat file to the burrs on the sides of the drive links. Once repaired keep your chain properly tensioned. Your saw is fitted with a chain catcher (page 9 of your manual), it did its job and kept the chain from smacking your leg (were you wearing chaps?). Burrs are often created when this happens.

If no burrs please repost. This has piqued my interest. I think a brand new chain will operate correctly.

Cannot get new chain on do i have to remove


Put it over the sprocket first, then work your way right putting it into the bar grove as you go, the nose last. Grasp and pull the bar right the chain should rise into grove, you may need to help. Loosen the chain tensioner some put the clutch cover on and tighten the bar nuts finger tight.
Chain adjustment
  1. Make sure the chain brake is off (gloves will protest your fingers).
  2. If necessary, loosen the nuts that are clamping the guide bar in place (or whatever your saw uses to hold the side plate and bar on with). We don't need these really loose - just finger tight will do.
  3. Ease the tension until the chain is obviously loose.
  4. Using one hand, hold the nose of the bar up.
  5. Now, while holding the nose up, adjust the tension so that the chain just touches the underside of the bar.
  6. Continue holding the nose of the bar up & tighten up the side plate nuts / bolts / quick-release system.

Chainsaw chain came off/is loose


You need to tighten the chain, and or remove and reinstall the chain depending on whether or not it has come off the drive wheel. The chain drive is on the right hand side of the saw, and there are either two nuts (about 1/2 inch or 13mm) holding the chain on, or there is a little half round handle you can use to tighten the chain after it is on the drive wheel properly. The saws with the two nuts on them have a small flat blade screw on the backside on the bar that you tighten the chain with. And to make things more confusing, some of the newer bars have a round hole in them, that after you loosen the two bolts, you stick a screwdriver in the hole and turn it clockwise to tighten the bar, then you re tighten the 2 nuts.
Since from your description that it wont engage to cut, you will have to remove and reinstall the chain since it is loose from the drive wheel. Clean out all the wood chips, etc in the drive wheel area before you reinstall the chain, make sure it is not on backwards and sharpen and oil it before you use it. Rick
