Our 261/msa300/362/400 Clutch Cover fits the full wrap 362 (R model) with Stihl part number 1140 021 1105. 

Older 261 models may need Stihl part number 1141 021 1130 to fit.

If you plan to run a 404 chain, you may need to shave 0.015 (inch) off the chain slider to allow for the additional width.

MS660/440 Clutch cover also fits the following models 660/650/066/064/046/460/461/440/044/046/036/034


Felling dog bolts need to be installed from the inside of the cover, facing out so that the nut is on the outside of the felling dog. After this, put the cover flat on a table and make sure that you pound the chain sliders down until it stops against the cover - as far as it will go. The clearances are super tight so we get maximum wear out of our chain sliders. Once they are down tight your chain will spin freely.
