Does it matter whether or not I use a PS-7910 or PS-7900 crankshaft? The one for the PS-7910 is substantially less expensive new for some reason.

I finally got time to tear the saw down, and this is what I found. The bearings slid right off of the crankshaft when I split the case. Flywheel side of the case. Flywheel side of the crankshaft.

Don't know what route to go with this one: I've put so much money into this saw recently that it seems like throwing good money after bad; but I can't get much for it now and a new Stihl costs quite a bit. I might need to think this one over before I move in on it. Looking at about $240 in...

Googled your thread. That sounds exactly like what's going on with my saw. I've noticed that the piston has some unusual wear (some might be from carbon build-up, but not all), although the carb tuned fine. Now that I think of it, when I installed the new bearings last year they slid on...

It's hard to tell with so much in and out action happening, but if I pull the shaft tight to the flywheel side (so as to eliminate any in and out movement) I don't feel any wiggle to either end of the shaft. After I replaced the bearings this time last year, they were all tight. What could...

Alright, here's a video of the issue:

It's in and out play. When these bearings were installed almost a year ago, they were tight and remained tight until just recently, and that's with pretty much daily use felling and bucking at work, not to mention milling work for myself later on. I'll see if I can get a video of it.

There's a bit of horizontal movement on the crankshaft (about 1/16th" at most), but no vertical movement that I can feel. How much horizontal play should there be with this shaft?

I didn't feel any when I checked recently, but I will check again tomorrow after work just to be sure. I hate to think that the brand new bearings may have gone bad, but it's possible.

huskihl: The saw has a plug instead of a decomp. I do away with the decomps on all of my saws, save for the 084s, because I've seen too many saws come in blown-up due to a bad decomp. hotshot: Yes, I meant 0.6 bar (must have been confused in the head when I wrote that). It won't hold...

Hey, everyone! So I recently noticed that my Dolmar 7900 was leaking bar oil out of the screw holes in the crankcase. The issue was that the screws around the bar and chain oil reservoir were backing out, so I tightened them down and checked the ones around the lower-end, which were all tight...

Found the perfect filter setup I was looking for. Thanks!

Anyone have an HD air filter base and cover for a Stihl 084av?

Yeah, I wasn't sure what might be out there as far as condition goes, but, like I said, I'd pay good for one in nice condition. I was more trying to keep in line with the condition of my saw, but good used condition is fine.

I need an IPL and service manual for an early version (West German made) Stihl 084av.

Nevermind my last question, I figured it out; looks like there is a non-slotted version (that must be the one that I need). Could also mod a slotted one. Really, no one has one of these setups on hand? I've seen a couple come up for sale on here in the past and thought that there might be...

I should also add that I have an HT-1A carb, which doesn't seem to have what looks to be an intellicarb feature on the metering side. A lot of the HD setups I've seen pictures of seem to have a slot for this. Do I need to switch carbs, or is there a setup that doesn't have the extra slot?

Hey, everyone! I'm looking for a NOS or good used condition Stihl 084 HD filter setup. I know NOS might is a bit of a high order, but I'm very curious to see if I can find one. Can't wait to see what's out there!
