Please check your saw, bar and chain setup as these models had multiple configurations . Ask if you do not understand.
Do not buy just because you have a 20" bar !!!
Saw Models that use the D025 mount and this combo MAY fit :
Stihl 024,026,028,029,030,031,032,034,036,038,039,040,041,042,044,045,048,056,064,066,E15,E20, 026C MS360, MS361, MS660, 066 - AND MOST OF MS MODEL EQUIVALENTS
*** 024, 026, 028, 029 and others may have come with .325 .063 chain setups.
We cant emphasize this enough that you are sure you know which setup you are buying.
The bar nose sprocket on this bar is made for 3/8 pitch chain it will not work with .325 pitch.
Many of the saws this bar fits came with both pitches of chain so the saw model doesn't make the bar unique.
We do not guarantee fitment by model, bars are sold by mount style and chain pitch, your saw must use D025 mount and 3/8 pitch chain.
