Cs 310 clutch cap nuts

I bought a nes CS 310 and when I started to loosten the clutch cap nuts (also holds the bar) I noticed they were VERY tight, possibly over torqued at the factory. When the nut was reversed the stud seemed to turn with the nut. I took it to the dealer and they were able to successfully remove the nuts. I've replaced chains on other saws and NEVER thought the stud was turning when reversing the retaining nuts. Has abyone else experienced this with a CS310?

SOURCE: Chain becomes very loose with little use

the problem with torqueing the nuts is that it's not enough tighting.i tell my customers that you need to tighten them as tight as you can get them.the nuts will not vibrate loose then.don't worry about breaking the studs they are very hard.

SOURCE: How would I replace the bar hold down stud bolt in

At our dealership we replace the Bar studs with Heli-Coil and locktite for $20.

NOTE: Remove the old stud by double-nutting and screwing out of the case and marking the end that came out. Take it with you to NAPA and get the correct Heli-Coil size and a small tube of BLUE Loctite. (Might be cheaper to let the Stihl dealer do it)
Hope this helps!

SOURCE: after new clutch sprocket &good bar &chain

have you made sure that chain pitch and gauge are the same as the sprocket pitch pitches can be 3/8 lo pro 0.50 gauge

.325 x 0.50 gauge , .325 x 0.58 gauge

3/8 std x 0.50 or 3/8 x 0.58 gauge or 3/8 x 0.63 gauge

you could even have the correct drum but wrong rim sprocket on it

worst case is you could have mismatch bar and chain

make sure that bar adjjuster assy is working correctly

recheck chain / sprocket pitches and bar pitch and groove

be sure that you fitted chain to rim on sprocket correctly when you fitted bar and chain?

is the clutch cover pulling down tight ?

have a look and let me know if and what you find

cheers paul

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

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.
