New project - 385xp
« on: February 04, 2013, 04:52:07 pm »
Hello again.  I have a new project that i will need some help with.  If you can put up with me, here goes. My plan is to document everything with this thread, with the hope of helping future noobs like myself. I also have about a billion questions to ask.

I picked up a 2005 385xp.  The saw was used by a logger, and is well used.  However, i put bar oil and mix fuel in it, and it fired right up with just a few pulls. Seems to run great, and is strong.  It has 160psi.  It appears to be bone stock. I only had the chance to make a few cuts with it.

It does have a few issues that i wanted to address, and it's dirty as hell, so i decided to start taking it apart to clean and fix the issues.

Known issues (before breakdown)
- fuel vent is present, but it leaks when the saw is tipped
- Clutch springs are weak
- Sprocket is WORN
- Clutch drum is very worn

Here are some photos.

Before i forget - Does anyone have a repair manual for this saw?  I have the IPL.

I started by removing parts, and degreasing and cleaning them.

The case has a leak below the muffler.  A little bar oil seeps through at the gasket.  The muffler gasket is also missing.  The aluminum heat shield piece was still in place, but gasket missing.

This saw has a Walbro carb.  The IPL shows a Tillotson.  Any ideas on this?  I don't know which model it is.  Not sure where to find the model number.

At this point, i didn't see the point in stopping, so i pulled the jug. First time i've done this. Here is what i found.

The cylinder looks like it's in great shape.  Very smooth on the inside, no scoring.  There is one fin partially broken off, but it doesn't seem like a big deal.

The piston seems to have some wear.  The machine marks on the lower part are no longer there. It's just very smooth. 

I took a ring off (didn't get pictures) and it seems to be in good shape.  I put the ring in the cylinder, to get an idea of the end gap.  It's not very wide, but i didn't put a feeler gauge on it yet. 

Does this look like the original piston?  Should i plan to replace the piston?  What about the rings?

Here is where it gets ugly.  At this point, the cylinder is off, but the clutch and flywheel are still on.  I swear i can feel a tiny bit of play on both ends of the crank shaft.  It may need crank bearings. 

I checked the big end crank bearing, and i can't feel any play at all. It seems tight.  I was able to view parts of the crank bearings, and it looks like all of the balls are present, along with the bearing cage.  I have never split a case before. 

Now, with the carb base removed, i can see the tank vent line.  There is a green piece that goes into the tank, where the line attaches. I think this is where it is leaking. The green part is loose inside the tank hole. By grabbing the vent line, you can move the green part in and out very easily. 

I haven't pulled the fuel tank yet.  I was hoping someone had a repair manual before i get too deep. The parts box is getting pretty big, so i hope i can remember how this thing goes back together.

This front AV mount seems to have a problem.  It has play in it, where it meets the tank.  The spring is not broken, but something isnt right about it.  The pics are an attempt to show how much it can move (probably almost 1/2")

The case has a broken piece just above the flywheel.  How important is that piece?

Also, how do i get the flywheel off?

I don't have a tool that will fit the clutch.  I might just weld something to a socket to fit in there.  Any tricks to removing a clutch without the proper tool?  I do have a piston stop.

That's it for today.  Any help or comments (positive or negative) are appreciated.

Thanks.

Nice thread. I have never owned a 385 so I am going to watch and learn too. 

I had a 2171 that had that whole piece above flywheel missing, never noticed any issues.   

Early 385's were know for bad crank bearing issues.

Side of carb should have a couple letters then numbers to tell you what it is.

Did anyone PM you a 385 service manual?  If not I will look to see if I have one.
