288xp oil leaking

[eigermike]

ok took it apart and have a few questionsm

 

[eigermike]

is there anyway to fix where the chain has wore throu the oil port? the oil hose looked good but you can see that maybe the cast is wore and is leaking here to?

Is that a crack above the bar studs?

 

[eigermike]

no it is where the chain had ridding and cut a grove in it!

I would use JB Weld and ensure that the proper stainless steel plate was installed. Other choices are have it welded up or replace that crankcase half with a good one.

 

[Warped5]

IMHO, I'd go with one of the latter two plans ... temperature changes and vibration will be the death of JB Weld.

forget welding, just does not work on the metal that these cases are made of, unless somebody knows a secret I don't!

Lots o guys can weld Mg. Im just not one of em. Thatsaid there are a lot of 288 cases floating around. Sign urself up for a new oiler too.

I've got a 288xp and I'm interested. How did the chain manage do this? Is this what happens with a rim sprocket and the chain gets too loose and jumps off? With long bars I've noticed it's easier for chains to get loose without my noticing it. On my husky L series saws, the thin stainless steel plates on either side of the sprockets are shaped in such a way to make it much harder for a chain to jump completely off. But on the 288 it seems it can jump off and still keep moving while its sandwiched between the body of the saw and the side of the rim sprocket - all the while grinding metal off your saw.

I just picked up a good 288xp bottom end on ebay for $150. It has everything except the piston, cylinder, muffler, and carburetor assembly. With some shopping around on the bay, I've got all the rest of the parts I need now and sometime this year will have a second 288xp at a cost of around $330 - I hope. I'm going to do a muffler mod and use it as a milling saw.

You could get that fixed if you can find somebody that can tig magnesium. I've heard it can be risky to do that, magnesium can catch on fire, and once it does, it's a spectacular brilliant fire and pretty much impossible to put out.

Maybe I will use the jb weld and look for a new case or I could try and weld it up and still look for a new case? I'm a decent tig welder

 

[eigermike]

i dont know how the chain did that i just pick this saw up.

It is flammable, but any good welding shop should be able to do it. I've had three cases repaired. ..

Nice welds. There is a need for someone that welds magnesium for the forum..

 

[Perry pioneer]

Those welds do look good on them manifolds

Pretty sure @srcarr52 does some really nice work. Ive not had anything done but ive seen some pics of finished stuff on here.
