What's on your bench?

[longleaf]

I can't leave you all hanging.

This is one I put together for @Mo Jim. Ported with a 395 piston, but it has a stock muffler outlet with spark screen, and stock carb. A little different from my normal build but it turned out very nice. FYI, I think it will be for sale soon.

Then there is this one I put together for Rod.

Very nice. What kind of chain/sprocket set up it that?

8 pin, 3/8 full comp, square ground.

It's a 52cc Efco 152 rebranded as a cub cadet 5018, thus 'efco 152 CC 5018'.
So not 152cc's...
Lol.

I mean, if there’s a 152 cc saw I wanna see that bastard pull an 18” Bar.

What chips?

See those little dark spots and slashes on the squish band?

They’re little gouges that have accompanying gouges on the piston..

How does the crank feel?

How does the crank feel?

Crank feels good but what do I know.

Not wobbling, no wiggle, no noise.
Feels pretty strong.
Rotates freely.
Connecting rod slides side to side along the rod without being sloppy.

But what the heck do I know.

I don’t see any blueing or other defects on the rod or shaft.
Is there a test that a hack like me can run to make sure?

Was planning on replacing the seals, which is something I’ve never done, so any links or advise is very very welcome.

I thank you all for your help....

The seals are nla, but they cross refrence to National part number 472705. I have used them in about 8 saws so far with good luck. Once you get the seals out you want to check the crank for movement. Up and down, and in and out. If you need help getting to that point pm me, and I can help you through it.

Freaking A!
Wish I could like that more than once!

Is this a “Drill out a pair of pilot holes, pull out with drywall screw?”

Don't really want any metal shavings going into the bearings. Usually a small screwdriver will pop them right out.

Plying from the outside of the seal using the case as a fulcrum?

Yep just put something between the case and screwdriver like cardboard.

The screwdriver between the crank and the rubber part of the seal. Be sure not to hit the crank.

Ok the FNG is at it again....so i got a 346xp AM job for the 351. Stock OEM is at .019 squish no gasket. AM is at .028 no gasket. With out a porter or machinist in my garage is it still an advantage to run a 346 closed port head over the 351 open port? Possibilities r still endless at this point, wer just in the test phase. Would like to hear the pro side. Thanks

Huge help sir.
I’m surprised I’m not in the shop right now (11pm) giving it a go...
Really Excited to try it after work tomorrow.

Do you already have the flywheel and clutch off the saw?

 

[J. Loe]

Clutch yes, flywheel no.

Don’t have a puller for the flywheel.

Suggestions?

 

[J. Loe]

Get a cheap steering wheel puller, and in a pinch can use the carb mounting bolts with big washers.

AhHa! Fantastic!
