Question about Echo 30.1CC Chainsaw With a 14 and Chain

Open Question

Bar nuts possibly over torqued CS-310

I bought a preassembled Echo CS 310 and noticed that the clutch cap nuts (holds the bar) were very tight, perhaps over torqued at the factory. When I started to removed the nuts the stud seemed to turn with the nut. I took it to a dealer because I didn't want to turn the nut and perhaps strip something internally. The tech at the dealership was able to remove the nuts successfully. Is anyone experiencing this?

SOURCE: how do I remove the clutch assembly from an Echo Cs-400 chainsaw

Turns out there is a reverse thread on the clutch hub (the "Y" shaped piece). I poked around some on the web and got some ideas, but they called for a special tool that it made by echo that fits in around the legs of the hub, and once you've prevented the crankshaft from turning by blockiing the piston, it turns (clockwise) with a wrench. I didn't have that tool, nor did I want to spend $19.95 to buy one, so I stuck a plastic toothbrush handle into the exhaust port to block the piston from moving, and used an open-end wrench just wide enough to fit over one of the legs in the "Y" shaped clutch hub. Then I took a large crescent wrench and closed it over the open-end wrench, right down next to the hub. So, if the saw is lying on its side, with the clutch facing up, the open-end wrench is inserted straight down straddling one leg of the clutch hub, and the crescent wrench is positioned horizontally gripping the bottom end of the open ended wrench to provide a "handle" for leverage. Holding the saw securely somehow (I used my elbow), left hand gripping the open-end wrench and pushing it down into the clutch so it won't slip out, I used my right hand to provide the clockwise motion on the crescent wrench as a lever/handle. Clutch popped free after a few seconds of pressure.

Hope this experience helps someone.

SOURCE: trying to replace gear on echo cs 440 chain saw

The IPL for a model 400 Echo can be found here:
It should not matter but please verify this fits your serial number.
From the IPL your saw has an outboard clutch. Use this the following as a guide. I didn't see any special tools on the IPL.

R² Drive Link Outboard Clutch

  1. Check at the IPL for your saw to see if any special tools are needed.
  2. A length of starter cord or nylon rope may be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
  3. It is probably a left handed thread (tighten it to loosen it).
    Let us know how it worked for you. GL

Need size of guide bar nut on model cs-330t

I went here, typed CS-330T in the search bar and found 6 IPLs. None of them list or display bar nuts. Odd!
I suggest you take your saw into your local NAPA Auto Parts store. You might also contact Echo and suggest they add bar nuts to their IPLs for the benefit of the next guy. HTH

Are you holding the nose of the bar up as you tighten the bar nuts?
You loosen the bar nuts and gravity pulls the bar down. You check the chain and the tension is correct, tighten bar nuts. Begin a cut and the bar slowly moves upward (no matter how tight the bar nuts) and the chain becomes slack.
19d6408.gif 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 don't 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.
One more likely possibility, is the chain isn't being oiled.
Checking chain lubrication
Aim the tip of the bar at a light colored surface about 20
cm (8 inches) away. After 1 minute running at 3/4 throttle
you should see a distinct line of oil on the light surface. HTH

I have an Echo CS-440 18" chain saw and the chain came off. Now that I have put it back on, it won't move either by hand or when the engine is running. Help

OK.  This is simple. Either the chain brake is engaged or the chain is too tight. Start by pulling back on the chain brake toward you.  There should be a "click" if the brake was released.  If the chain is still immovable, try resetting the chain tension. 1. remove the spark plug wire 2. loosen the two clutch cover nuts 3.hold the bar nose up and loosen the tension adjustment screw until the chain moves freely without becoming loose. 4. tighten both clutch cover nuts with the bar held up. 5. Pull the chain around the bar by hand.  Loosen the adjustment if you feel tight spots. 6. When the chain is properly tensioned,tighten clutch cover nuts securely.  Do not overtighten! 7.  Check chain brake operation and release. 8. Replace spark plug wire and operate  saw.
Hope this solution will Fixya.
