Homelite 770G resurrection

[jeepsnchainsaws]

So I got this one from the son of the original owner. Although the paint is rough it seemed to be in really good condition... Until I saw this!
The crankcase broke right between the clutch gear and drive gear.

My first thought was to post here on the site for s crankcase, of course
So after doing so @sawnami says there is an NOS crankcase on Evilbay.
Much thanks to him!$35.09 and it was on my porch. Zoom in on the UPS label, it says 1964 on it!

After getting the whole thing apart it seemed to be fairly low hours.
The P&C look great!

Nice project. Best of luck with it.
I'm in the process of doing a 770GS stick shift
but I'm at a road block with a few missing pieces
And I started this project almost two years ago.

The press work involved in this gear box took some time to figure out, 3 different setups for the down and 2 for assembly and THEN the crank!

That stick shift is so neat! I hope to find one one day. What are you needing, I can keep an eye out.

Due to being very excited/impatient I made all of the gaskets needed.

I need the brake parts for the clutch drum. It's the second button you press to
stop the drum before you shift it. I haven't been hard looking for them just
kinda put it on the back burner. All parts painted, motor together, decals applied.
Also need a full wrap handle for it. Specific for the GS model as it is wider to clear
the chain case.

I am very thankful the carb wasn't as dirty inside as it was out, 1/2 hour in the purple, a kit and brand new again.
These recoil start assemblies are for the birds! Like 24 parts from the flywheel to the rope! Yuck!

This is the part where the design of this saw goes total hunchback!

That's what I thought at first but not so bad after I found the R&R procedure in a manual. Check the ball drive torque before you get it together. Let me know if you need any info Adam.

I've had several that someone pinched the broken end of the recoil spring in the split in the ball drive slipper to anchor it then found out that it would no longer turn the engine over.

The recoil consists of three balls that are supposed to engage the starter pawls, this is a very touchy design. Right now it will only engage if I shake the saw before I pull the rope.
Although I have the recoil cap which is usually the missing part on these saws, I don't have a cylinder shield yet. It will run without it, but helps it cool itself.

There should be a ball in every slot so if the motor stops in different positions
the starter will grab. The balls the cup and the drive part need to be clean and
dry or the balls will not fall and engage when you pull the rope.

Yes sir! Check on all that. It sure is a pain!

They're a little challenging getting them back together when they're nice and clean. It's one hell of a smooth operating system when it's functioning right.
