Rough day.

[bwalker]

I managed to crunch my Dolmar 7900 with a Skidder today. If that wasnt bad enought my 260 I brang as back up blew up....One of those days I should have just staid in bed...Time for a beer

 

[ehp]

So no more oil leak , at least from the pump line


how bad did you crush it?

 

[MasterBlaster]

Probably pretty bad.

That fooking sux!

 

[bwalker]

how bad did you crush it?

Handle, ignition switch, airbox cover, airfilter, airbox cover clips, rear handle, side/sprocket cover and gas cap. At least thats what I noticed

 

[bwalker]

On the bright side its still not leaking oil.

 

[ehp]

not good , those parts are the ones worth money, if it did not hurt the motor than i guess fix it but check the crank to see if she is still straight, just put a bar and chain on it if you can and leave the chain real loose, turn your motor over and see if your chain on the bottom side goes up and down

What went wrong with the 026? You don't see many 026's coming apart.

It seized. I havent been inside it yet so I dont know what caused it, but I suspect it was a air leak.

 

[ccicora]

Ben was probably trying to perfect that carb drill haking thing and the moblie mtx got mad and left.... And then he had the worst noise any sawyer hates... quiet followed by a really big F@#$!!!

Either way Ben Me and the guys would like to know what happened to your prised 026.

Later,
Chris

Just tore into the 260. Looks like a air leak. Burnt some of the piston away on the exhaust side. It broke free relativley easy and the cylinder looks saveable with a little muritic acid to remove the aluminum. Looks like a new piston and rings and I will be back in business.

And new rubber component or whatever leaked the air into the crankcase...

So, did you end up making any money today?

I suspect, although I do not know, that the cause of the leak was the clamp on the carb boot. I have had a problem with this before and its a trouble spot with 026's. of course I will be replacing the base gasket and sealing up the intake boot well with three bond when I put it back together. I will aslo check the crank seals when its running again using the map gas method.

 

[bwalker]

One more thing I thought of. The decomp button. Thats going to be replaced with a brass plug from stihl. I do not know why they would put one on a 50 cc saw anyway.

 

[rmihalek]

Be prepared to pay a bit of $$ for the intake boot. I just picked up one today for my 028 and the dang thing was $30; all that for a 2" piece of rubber tubing. I knew I should've tried to make one, but I figured the factory job would fit a but better. Sorry to hear about your 7900 getting crunched. Didn't Gypo just run over a 385 with his skidder?

 

[JimL]

the compression releases are problematic ive found.

a plug works

 

[bwalker]

Didn't Gypo just run over a 385 with his skidder?

yep. It looks like John Deere is claiming its fair share of saws lately.

 

[MasterBlaster]

I tried my best to cover that problem on no. 8.

MB, The saw was riding shot gun in the skidder with me. Typicly I put the saw in the cubby hole in font of the log arch, but for some reason I had it riding at my feet today. A bump in the trail and a skidder at full clip was all it took to toss the saw towards the rear tire.

 

[MasterBlaster]

So I guess the moral of this story is to not deviate from normal procedure, eh?

:angel:

Ben, Gypo posted a picture of his kill. How about a photo of your mishap?
