Tearing down my JMSSAWS, one by one...

[Moparmyway]

ok alot ugly in the cylinder for the little bit of use its had

Probably because the base isn't perpendicular to the bore

This pic isn't as clear, but it's another one of Jason's

You tear this one apart deets!

I would assume if that were the case it would have the same wear on the exhaust side. It just came to mind at the time so I rambled about it.
You can use a set of internal or regular calipers to check.
Shawn noticed a texture to it, so it's looking like it'll need a little honing with fine grit.

Jim, I checked to make sure the jug is round. It looks to be perfectly round, measured with calipers.

With that said, mufflers really aren't his thing. This was brand new, never touched when I sent it out.

Yup. I've done a bunch of these crimped Dolmar mufflers by now, and it really isn't that hard to do. The inside on these 5105 mufflers is very simple to do. Grind down the spot welds, and remove the whole cat and plate that holds it. This one has just been cut off with a cut-off wheel, with lots of loose boogers left, just waiting to let go and wreak havoc.

It may just be the pics, but I don't like the way that cylinder looks under the exhaust port.

I fear Dallas & Kevin may be on to something. I would have that cylinder checked.

Looks like *s-word to me

They're all going to Kevin @Moparmyway to get checked. He's offered to check and true up the jugs. His generosity is incredible.
If they're trash, I'm not putting them back on. Simple as that. I'd rather save up and put new non ported p/c back on them than to run them until they blow up, and possibly damage more.

I'm sure they'll clean up fine

How great is it to have the good people we have on this site ... Good on you Kevin!!!

I will twist an old saying: When you are a friend to someone in need, you are a friend indeed!!!

That's not an issue, you just have to split the gasket and use only a half to make this straight.

Not just me Sir, Doc Al @drf256 is going to be setting up his lathe for this as well. Easier to ship everything to me, then the good Doc and I are going to work together on getting you all squared away ........ nothing like teamwork to get the job done !!

The horizontal lines looks like he buffed the cylinder with pretty coarse emery cloth. I don't know why, it shouldn't have had transfer when sent to him.

Catching up here but that was my thought too... wonder if it is the same OEM jug?

I've seen worse.

Except those mufflers. DAMMIT !!!!

How much runout in the mandrel is acceptable for checking things? I've got it under .001.
Can't seem to get it better than that.
Mason is bringing his 395 jug for me to check for him.

Just in one spot? Or is it within .001 all way up the mandrel?

 

[paragonbuilder]

Just tried one spot.
