echo 450p
« on: September 23, 2015, 11:47:34 pm »
I created this post for two reasons. First one is this site is cool , calm and full of knowledge. Second, I have a 450p and would
Like to switch it over to 3/8 LP. Was wondering if anyone could help me with sproket, 20" bar, part numbers. I feel this combo would benefit this saw more. Any help would be appreciated...

 I did the switch  on a CS4400 and it way better with the 3/8 lp  6 tooth driver, I tried a 7 tooth driver first which cut about the same as the .325 chain.  A sprocket off a CS400 fit on the CS4400 but I had to machine (grind) a little off the end.  I did some timed cuts between my CS400 and a CS450 (with the .325 chain) and they were about dead even. With the 3/8 6 tooth lp on the CS450 it should cut quite a bit faster than a CS400.  If you find a 6 tooth sprocket that fits right on let us know.   Steve

Ok , i was thinking that finding a sproket will be the easier part of all this, Bar in 20'' 3/8 lp will be a bit harder , i was thinking of using my .325 pitch bar cause its a .50gauge and that is the LP i am going to be using , so i could probably moddify the nose sprocket of that bar to run the 3/8 lp i got that bar on sale anyway from baileys...lol.. So the sprocket from a cs400 will fit huh?

Your saw? http://www.ereplacementparts.com/echo-cs450-45cc-chain-saw-parts-c-35043_35970_160062.html

You have small or standard rim?  I just put a 3/8 7T on a saw. Works fine.   See if your 45cc can pull the 3/8LP with 7T.

I dont know anything about cross referencing this saw.  @mountainlake might know

It pulls the .325 with authority, i have done a MM and tuned the carbed on it, it rips. And to be honest i dont no if it is a standard sprocket how can i tell i know they make a conversion for it to go 3/8 full so im assuming that 3/8 full sprocket would work on a LP size chain, cause there both 3/8's. I honestly think i can mod the sprocket tip on that bar, How long is that orange bar u have the LP on in the pics on the treehouse? If i can mod the sprocket nose on my bar would u make me a loop of 3/8 lp i would pay of coarse. ;D

This is small 3/8 7T and a 3/8LP chain.  I would bet yours is small hub too.

 After you find the right sprocket I'd just buy a CS400 bar with the 3/8 lp, I think if you go with the 3/8 lp 6 tooth your going to be stuck with a spur sprocket, no rim sprocket with 6 tooth and I wouldn't bother changing from .325 7 tooth  to a 7 tooth 3/8 lp as they cut about the same.   Steve
