391 rebuild, HELP! Please?!

[michaelmj11]

I don't recon you do.
I simply stated 500 is a good price.

Agreed

Ok, will either of these work?


And if not, then will any of these:

I was hoping to find some of that loctite 518 stuff. Because in the Favorite Sealant Thread it sounded like the 518 was more forgiving to those who moved slower.

I'm thinking the black "should work" but there may be a convenience thing against using it.....I have personally not used any of them options you pictured.

 

[jmssaws]

I have used the black and it works just fine.

Ok so is there something better to use than that Black tube, or am I good to go with it? Because I did not go by NAPA or the Honda/Yamaha dealer, and could easily get something else.


So now that I have Sealant, I need to clean things off (if the tornadoes don't get us). After things are cleaned, what is the next step?

I use Dirko that I buy from a stihl dealor but I've used black permatex many times.

Clean it up and put that joker together,
Have you got a ring compressor?

I don't even know what a ring compressor is. If you mean just an air compressor, I have one of those.....

 

[jmssaws]

It's to install the piston in the cylinder but it's not necessary to have. I use my fingers or a pencil or little screwdriver

Jay, Mike
No need for ring compressor on this series....it wiggles in together as there is a slight taper....
(think teenage summer nights)

 

[jmssaws]

I don't own a ring compressor but I've bn thinking about getting some.

I always use the plastic end of a stihl screwdriver.

Some day you'll get old and chit don't work, like yer eyes, fingers, hands ect....tools help lots.

I got a cheap set from baileys for like $8. Has a plastic stop and a piston block to rest the piston on by the skirts. Money well spent.

 

[jmssaws]

I've been meaning to order one.

You should have said so earlier and should watch the HL deal of the day. They had a real nice set for cheap cheap a couple Fridays back. I almost bought a set and have no need for them.

well if you see a good vacuum and/or compression testing... stuff... Testor? I would love to know about it. I have no clue what would be crap brands and which would be worth the expense.... will I be needing Torque wrenches for putting this thing back together?

No torque wrenches if you can tighten a bolt to where it doesn't break off or loosen up lol. I wouldn't worry about a compression tester. Or a vacuum test kit if your shop can do it. Unless you're gonna do this to 10 or 15 saws

Fair enough.

Although I would love to get further into this, so who knows

If it happens, you can always get tools. All you need for this it a long t27, a pair of needle nose pliers, vise grips, a half a dozen various screwdrivers, and a bfh

That's a big 10 4 on the BFH.
