Sprocket rims

[wisewood]

Hi I'm looking to run 3/8 picco / lo pro chain on an 026.

Which rim should I get, from what I can tell there's a 7 pin and an 8 pin picco 3/8 rim not including normal 3/8 rim.

Anyone done this ?

I've been running 3/8 picco chains on my 261, really do cut quicker, think there's a vid on YouTube done by stihl

 

Really don't know if it's 7 or 8 but google may help

If its a standard saw ( not ported ) then only use an 8 pin on relatively short bars . Just me .

another question has anybody taken a 42cc saw running 325 chain back to 3/8 to use a picco chain i have been toying with the idea for a while hopefully it is possible cheers

This is what I put on my 261 c-m, recommended by Stihl in the 2013 catalog:

 

part no.

3003 000 6313. 16 " .050 guide bar

7 toothed sprocket:0000 642 1240

 

3617 000 0060. the new out(2013) Picco Super full chisel chain.

 

Hardest thing to obtain was the chain,but I suspect Rob has these now.

 

Really good combination in my opinion....

Hi Pinkfoot,

It's the 7 toothed 0000642 1240 that I have, so will see how it runs. I'll be using with oregon 91vlx

A great formula is the 95VPX .325 050 low pro chain and just change the bar to a 150MPGD025 or 160 or 180 for 15-18"

using 95VPX062E 067E or 074E chain lengths, this has been featured on Arbtalk and many on here have tried and use this. Faster cutting less vibration and you use the standard .325 sprocket.

 

A 15" bar on an 260/261 is about 10% faster using this chain set up

8 up from standard 7 raises the gearing giving a faster chain speed provided the motor is powerful enough to drive that higher gear . The longer the bar the more work the motor has to do . raising the gearing and a longer bar may make it under perform as it cant generate enough torque to drive it and may end up actually slower . This can cause other problems like soothing up the plug as the motor cant " rev out ". If however the motor has had some porting work done to male it run stronger and faster then sometimes you can make use of that extra grunt and up the gearing .

hello les would this fitment work on a husky /dolmar 15'' 325 bar

[Les Cork]

depending on which saw you wanted to fit this to as 95VPX .325 .050 is intended for saws up to 55cc in which case you would need a 150MPBK095 bar and a 95VPX064E chain.

I wouldn't run this on a 357, 560 372 etc as they would be too powerful, I have seen it on 435, 346, 445, 450 and 550 series all ok.

And mid range Dolmars on K095 mount up to 55cc would be ok on .325 chain already.
