Craftsman GT5000

Post  Admin on 4/20/2008, 22:24

After searching and asking lots of questions I have finally found out why these things smoke on start-up.
I have come to the conclusion that there is a manufacturer's defect. As far as I can tell, everyone with this mower is having the same problem. The head gaskets are blowing near the oil galley letting oil seep into the cylinder.
When I took mine apart there was about a half a tablespoon of oil laying on the piston.

me too, I own lots of craftsman things. I just happened to buy the one tractor with a defect.
I even contacted them and they told me it's normal for them to smoke when you start them up. LOL

Yeah, sure! It may be normal for it to smoke if you have oil in the cylinder, but it's not normal to have oil in there in the first place. What a load of crap. I hope they don't go downhill. I really don't mind paying for quality but if you can't expect it...

Not only is it bad for craftsman but it's bad for Kohler as well since it's a Kohler motor.
I can't figure out for the life of me why Kohler put the oil galley so close to the cylinder wall.
They can't expect the head gasket to seal it off from the cylinder when it's only a quarter inch away.
The cylinder compression is in the area of 100 psi, that's like putting a piece of tape on a hole in a air hose. affraid

You should be good with the head gaskets. I haven't had that issue but if I park nose down it will smoke on the re-start.
I figure it's oil running past the rings. I have an 05 cv730. 345 hours and I am a kohler fan.

I sure hope I'm all set, I shouldn't have to put new head gaskets on a new motor..LOL
Yeah, I just mowed for the first time afterwards and it still will do it if I park on a slope..
At least it clears up now, it wouldn't before..

The only thing I'm not satisfied with is the scoop ( it ain't worth the money and I'll be taking it back if I can) Sad

Any problems with any of these?

Yeah, I couldn't find a rear tine tiller there when I looked, I ended up getting a front tine.
I looked into getting one of those scoops for mine but it didn't look like it would hold up.
It don't even work does It?

This F*****G tractor blew a head gasket AGAIN!!!
I'm going to e-mail Kohler again and tell them that their cv730 engine is going to be a F*****G boat anchor and that I'm going to put a Briggs on this damn tractor.......
Then I'm going to e-mail Craftsman and tell them the same!!!!

They changed the head bolt style since that 'defect'.
You may want to try that before you deem it RIP.

I got that hardware update kit when I bought the gaskets for it.
Now someone on another forum is saying that you have to get new heads....

Well... What's the verdict? I haven't heard about heads yet.

I'm curious.. if you have the heads off, tilt the unit so the nose is down. I'm wondering if your getting oil past the rings and it is creating a hydrolock inside the cylinder. The same could be caused by a head gasket I suppose but I'm curious. What torque did you use on the head bolts?

Peace

I know where the oil is coming from, it's the little area where the oil galley is real close to the cylinder wall. The head gasket blows right there and because its so close the oil runs right in the cylender. Dont remember the tourque but it was whatever came with the directions.
About 35-40 I think..

Some have told me it's the design of the heads, well i dont see how when its the oil galley being so close to the cylinder on the block side..
