From the image and comments looked like you were using 518 liquid gasket between the cases like a dirt bike would ?

LOL
No sir
Using a gasket.

Looks like this...

The surface that the oil pump mounts to needs to be an uncoated machined surface. Particularly with an 044/440.
I can't speak for any other saws though.

Just double up the gasket and forget about smoothing out the mating surfaces [emoji106] double down on the tourque and she be aight

Right!

Ummm ..... Why dose the surface for the oil pump need to be a clean machined surface ????? Sry I'm getting ready to go through my 440 hence all the greenie questions

That sets the bearing depth which is critical on the PTO side of a 440/044

 

[Adirondackstihl]

Right!

The one I got here sure don't look like that!

I didn't know that it was a area that needed masked until randy said something too me now they all get masked off

still learning is a good thing

Interesting .....

I've started them as quick as it takes to assemble and no problems.

Good to know Mike! Thanks! I got to see that 372xpw today! Nice

When installing the PTO side bearing, you must mount the oiler body to create a positive stop for the bearing.
The bearing depth on this side is particularly critical further along in the assembly process.

As is all saw that use the oil pump as a bearing stop.

Why is this so important ?

 

[glock37]

I can geuss its to keep the crankshaft from rubbing against the inside of the crankcase if bearing is set to far outward

Which would be Jeremy? Wouldnt the c ring on the shaft prevent it being too far out?

There is no C ring on an 044/440.

The seal presses into the bearing. The spacer sits inside the seal. The shoulder on the spacer is only "so" wide. And if installed properly, there isn't much room for error before you created an airleak.
See where I'm going?

Good deal. It runs pretty good. I ran it with a 34" I believe a few times.

We only cranked it Mike . We were too busy helping ole Laslab put this beauty together

Yes now I do. What does the c ring do on the 460?

Never had a 460 torn down on my bench but I'm assuming it sets the bearing depth

Cool bow saw

This was Johns first full restoration and he did a great job. 046 with d cylinder, cleaned all the ports up, MM, deleted base gasket and dreassed the outside up. The saw is immaculate internally to be a saw of age.
