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.

When do you change the fluid in the rear differencial. I was told by a mechanic that the rear differencial fluid was low and had metal shavings in it, and that the fluid needed to be changed and that it...


I'd say yes. The differential fluid is often overlooked by oil change technicians, even though it's something that should be topped off periodically.

It probably would cost more than that to repair it once it wears out.
Axle Housing Assembly Removal & Installation To Remove:
  1. Lift the vehicle.
  2. Drain the lubricant from the rear axle housing.
  3. Remove the rear axle assembly from the vehicle.
  4. Remove the brake caliper brackets from the rear hubs.
  5. Remove the rear cover and gasket from the rear axle housing.
  6. Remove the rear axle shafts from the vehicle.
  7. Remove the rear differential assembly from the vehicle.
  8. Remove the brake backing plates from the rear hubs.
  9. Remove the rear drive pinion shaft yoke and seal from the drive pinion.
  10. Remove the drive pinion from the rear axle housing.
To Install:
  1. Install the drive pinion into the rear axle housing.
  2. Install the rear drive pinion shaft yoke and seal onto the drive pinion.
  3. Install the rear differential assembly into the vehicle.
  4. Adjust the differential side bearing preload and the backlash.
  5. Perform a gear tooth contact pattern check.
  6. Install the brake backing plates onto the rear hubs.
  7. Install the rear axle shafts into the vehicle.
  8. Install the rear cover and gasket onto the rear axle housing.
  9. Install the brake caliper brackets onto the rear hubs.
  10. Install the rear axle assembly into the vehicle.
  11. Refill the lubricant in the rear axle housing.
  12. Lower the vehicle.

I think that changing the fluid would take about an hour, and depending on the garage, and the labor rate, that they might elect to take the rear cover off of the differential, and drain it that way and replace the fluid once it was put back on. He could inspect the gears while the cover was off and tell you how bad it was.'

Do you hear any clunking or gear mesh noises from the rear when putting it in gear or running the vehicle?


Some mechanics would simply top off the fluid and wait until it wears out, which could be several thousand miles in the future.

Use gear oil for it of the recommended viscosity in the service manual.

Generally thicker than motor oil.

So, adding fluid would cost only the amount of the fluid plus some labor.
A bottle of fluid might cost $9.99 or so depending on where you get it.

You might be able to do this yourself if you crawl under there, remove the fill plug at the top, and just add gear oil. If there isn't enough room you might drive it up on some ramps and then crawl under there.

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.

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!

Replacing the rear rotors on a 2003 E320


So this is what it takes to replace rear brake rotors on a 2003 Mercedes E320;
1) open the bonnet (hood) of the car and loosen/remove the cap off of the brake fluid resevior.
2) remove outer spring clamp from brake assembly (it clips in to the iner edge of the holes of the caliper).
3)using a 7 MM allen wrench, remove the brake caliper.
4) using 18 MM box wrench, remove the caliper housing assembly off of the wheel hub.
5) using a star wrench, unscrew the rotor locking screw from the rotor
6) squirt some liquid wrench on the rotor hub and knock the rotor with a hammer to work the liquid wrench in.
7) using the same hammer, knock the rotor off the hub.
8) using a metal file, lightly file old residue off of the hub and place the new rotor on the hub.
9) set the hub by screwing in the lug nuts and then screw in the hub locking screw using the star wrench, then remove the lug nuts.
10) reinstall the caliper housing assembly onto the wheel hub using the 18 MM box wrench.
11) push back the brake claiper piston to its home position and install the inner brake pad (the one with the snap clips)
12) insert the outer brake pad in the claper housing assembly.
13) slide on the caliper housing with the inner brake pad in place (over the outer brake pad) and screw in the caliper screw rods using the 7 MM allen wrench
14) on the right wheel brakes, DO NOT FORGET to slide in the brake sensor (the one with the black connector) and connect it to the connector on the caliper housing.
15) be sure to reinsert the spring clamp onto the outer brake assembly to set the assembly squarely onto the wheel (there should be no wiggle in the brake assembly after the spring clamps are installed).
16) finally mount the wheels.
17) you can bleed the brakes at this point to release any trapped air (which is unlikely) but be sure to pump the brakes after starting the car BUT BEFORE MOVING IT to re-preassurize the brake system before driving the car.
17) ONE WEEK LATER - recheck brake assembly to ensure all is okay and brake fluid.

This proposed solution is for a 2003 Mercedes Benz E320 and NOT a 2005 model as stated by the limited option selection provided by FIXYA.com when initially describing the problem.
