Next up, round 2-288xp rebuild

[roadster27]

Early KS (kolbenschmidt) non decomp 288 cylinder.

Use the mastermind method to sand the transfer off with a split mandrel and aluminum oxide emery cloth.

Thanks. I think I have seen that before in a video somewhere... I'll try it. And see how she cleans up.

That's what I'm talkin about....! Lol
But I'm 35, 6'2", 230 lbs, and young and dumb.... lol

I tried to take a reading today. I failed. I pulled it over twice and then went to lunch. I meant to swap the jugs and piston today but I just ran out of time.

I think I may be going all the way on one of these saws now.... who does powder coating. I've heard @Glock37 is the the guy for it.

That's the right guy, and he does a great job.

The cylinder had had some grinding done....
View attachment 148951 View attachment 148952 View attachment 148953 Also we now know how it became a parts saw...
View attachment 148954 View attachment 148955 I will see if the aluminum transfer will clean off the plating. Is there any special tricks for this. I don't really want to do the acid....

That things needs to call a domestic violence counseling center. It must scream, tho.

You might be young, but a new recoil assembly is gonna cost you the same This is on it's second in 3 years.
I am still waiting on the local dealer to get the needle bearings in. I didn't want to do this swap with both the old ones in. Was supposed to be today

I'm falling behind...

Well I'm back to the pair of 288's. I got the transfer off off the plating in the second saw, but think I got a little to happy with the Emory cloth around the ports. Think I should have started with a more aggressive grit, would have worked fast and I wouldn't have "sat" as long around the port..... oh well. This cylinder was a long shot to start with. I'm not a big fan of the last guys idea of a port job.
What do you guys think if I run it? How do you think the plating will hold up? I don't care about the cylinder, but it needs new piston. I don't want to spend a bunch of money on this top end but would like to see it run and maybe learn a few things about the last porters ideas of what it should be. Not sure if I want to buy a meteor just to have it ruined in the bore. Or end up having a bad cylinder from the start as new cylinder already come with pistons.....
If anyone had an ok use piston for cheap I might be interested.

After:what do you guys think if i run it with the plating like that. I don't care about the life to much....

From the pictures, I'd run it on my own saw. I don't think it would hurt anything. Meteor pistons aren't to expensive if you do have a problem.

+1 for running it.

 

[Fruecrue]

Run it.

I know this is a question often asked and covered, most of you have your own way that works well for removing flywheels. However This question always seams to resurface. So I made a video on how I remove my flywheels.

I built these knockers on my lathe and cover the details in this thread on the first page. They say a picture is worth a thousand words so a video must be worth 2 thousand...

At the 38 sec mark you can hear the difference when it pops free.

Somebody did a nice job opening them lowers to mimick a Jonsered 930.

These 288 are tough saws. I clean out half pound of oil soaked sawdust from mine. Put a new hyway kit in it and base gasket deleted. She sings.
The original P&C was so worn that the piston is 0.2mm smaller than the bore. But crank and bearing seems fine.

Yes sir they are definitely tough. Same crank is used in 394/395, bullet proof bottom end for the smaller 54mm bore of the 288. Great saw.

That bottom end is bulletproof @56mm bore, IF taken care of. And limit 4ft bar use.

I got the 288 back together. All I did was give it some more intake timing and width, but nothing crazy. And I opened up the bottom transfers maybe 4mm to get rid of the lip mainly. I want a mostly stock running saw. And it did have that great stock idle we're used to hearing, but a much better throttle response. It did... the wiring is messed up. So got to repair that. I'm away from the estate for a bit here, so shes still sitting

Anyone got a wiring diagram so I don't mess it up since I prolly won't see her for a month, and god knows who is gonna mess with it when I am away...?

Blue wire to kill switch, red wire to secondary coil in carb box

Edited to correct wire color to coil

Yep.

Hi everyone. Sorry to dig up an old thread but I’m FINALLY back on rebuilding These pair of 288’s. Last post from me looks like a year and a half ago. The saws hasn’t move from the bench the whole time. I just worked on my other projects around them. Its been to long and I would like my bench back lol.

You might think it took a while to update, but it wasn't. Lots of guys living in the real world dont have all the time available to them. I'm at the same point with a very special 024 that was given to me.
