6401

Since upgrading my 6401 to 7901 I wanted to try out an 8-pin sprocket to take advantage of some of that extra power. I bought the appropriate Oregon 22273 rim sprocket to give it a try. Everything fits just fine except that the chain now hits the rubber chip guide/deflector. Looking at the...

A couple of weeks ago I upgraded my ex-Home Depot DCS-6401 with a genuine OEM 7901 piston and cylinder courtesy of Chainsawr; installed a new metal base gasket, didn't bother measuring squish, didn't touch ports/timing/etc. Assembled just the way a 7901 would come from the factory. At the same...

I recently upgraded my former Home Depot rental DCS-6401 to 7901. While doing so I took the opportunity to freshen up a few things like the guide plate, chip guide/deflector, the "sponge" near the chain brake lever linkage, chain catch, etc. A little back story... When I got the saw the...

I'm looking for a Makita crankshaft to finish my build. The clutch drum bearing wore into the shaft and created excess play. I don't think I can get away with repairing it thus the search for a used crankshaft. Let me know what ya'll got. Any of the crankshaft's should work from that series, as...

So I recently got an early 6401 ex HD parts saw and was intending on putting a BB kit on it for my chainsaw mill. Piston and cylinder were scored, and I expected it to have been run lean or without mix. I was moving the saw around on the bench and noticed that the flywheel had some lateral slop...

I've had this Makita dcs 6401 since 2008 and it has worked great until i was cutting thru some nice oak when it lost power and stalled. I waited 15 minutes to cool off, pulled cord and no compression (easy pull). I installed a replacement big bore kit after finding some damage (i think I can...
