400.1 first impression

Yesterday I get my 400.1 here are the first pics and some infos I found.

u can adjust the oil pump with the Stihl wrench. There is no pin to push in for maximum oil flow

The big clutch cover from 462 /500i will fit perfectly. But the dogs won’t line up. The outer dogs from the normal 064/044 set are about 6mm more advanced then the inner one. So I cut the spikes shorter about this amount. I have to drill a fitting hole in the inner dog for the chain catcher.

The air filter is from the 462 not from the 362/old 400.

the muffler is a open can.
I like how u can mod the muffler outlet under the deflector. U don’t need a second one.
The exhaust has a pipe that goes into the cylinder.
And the cylinder has a step in the exhaust port. See the pics.

Handling with 28 lightweight bar is fine. Only a little bit nose heavy.

I will test this combo the next days

Do u want some more details pics, give me in info.

Any chance of finding out approximately how much the bore or stroke is? For the 400.0 I think it was 50 and 34 mm.

@DND 9000 do u know that?

 

[DND 9000]

No.

step in cylinder

Don't know what to think about this and the pipe going into the cylinder. I do like that it's an old school empty can.

Some of the smaller Poulans were almost there, they had an insert that went into the cylinder that could be taken out, but the insert was not connected to the muffler. I see the plus and minus of this. Plus = more seamless transition from cylinder to muffler, unlike having to line up a heat shield, gasket and muffler. Minus = seam farther in for carbon to start sticking too and building up. Adding a different muffler will need the insert or some way to jimmy-rig the connection between the cylinder and the muffler.

Won't be a minute before that pipe and step get deleted with a muffler mod. Probably already happening.

Dolmar has introduced such a "portliner" in some of their saws, citing Kubota as a prior art.

Stick something in the exhaust port to measure the piston width, we'll calculate the stroke from that.
