how much moisture to freeze up engine

thebigyellowtruck · Jan 17, 2011

Ive had my WD parked all winter because I've been trying to fix the fuel tank and buying new wheels and tires. Ive been going out at least once a month to turn it over. Today i went out to turn it and the hand crank wouldn't budge. I have a can over the stack. could enough moisture have gotten in through the carburetor to freeze up the motor? Could water have gotten in where the stack meets the manifold? I didn't tarp the motor. I changed the oil about a month before i parked it and only ran it a few times. There was no water in the oil when i changed it. Thanks in advance for your help.

It is very common for Wd's to allow water to let water in where the stack meets the manifold. Their manifolds have a serious design flaw. I would say the bigger question to ask is how much do you turn it over? In the winter I think it is generally better to just let them sit, because if you are just turn it over once or twice all you are mostly doing is removing ang residual oil from your cylinder walls as it is too cold for new oil to circulate to recoat them. Another possibility (although I have never heard of it affecting neurtal) is ice in the transmission.

i pulled the trans dipstick and there was no water. I'll leave the tractor alone until it warms up. Has anyone heard of a way to seal where the stack meets the manifold? Maybe exhaust putty? Now that I know its an issue with the wd i'll tarp the engine so no more moisture can get in the manifold. Thanks.

Pull the plugs one at a time ASAP because if it has any water in any of the cylinders and it freezes you could be looking at having to rebuild that engine. Reason is if it where full enough and froze it could crack a sleeve and then you up the creek. If you find any ice in any of the cylinders pour in some HEET and then let it sit a day or so then fill the cylinders with ATF and cover it up better. Then and only then can you let it sit till it warms up. Had something like that happen to me last winter on my Oliver 77 and I found that #5 cylinder was almost full of ice. I did the heet thing then once the ice had melted because of the HEET I spun it over and got it started up. And let it runn till good and warm

exhuast putty should work. My dad used to buy (I think from allis) something that was similar to an exhaust expander/reducer. It clamped to muffer then flared out over top of manifold. Neither of us have been able to find them in many years. He just keeps his in the shed now and I pull the muffer and cap the manifold on mine since it sits outside for extended periods of time.

Trans does not have a dipstick- only the engine and the hyd reservoir have them.

What funky G told you is working well for me, in rainy Puget Sound area. I have added flanged pipes to both my Allis B, and my wd45, and have had several years of success. I went to shucks auto parts, and bought exhaust pipe adapter pieces,(about 4" long), that the ID would slide up on my muffler, and let the flanged end hang over the manifold , then braze the new pipe to my muffler. It makes a little umberella over the manifold joint, and can still remove the muffler when needed.

Did you try blocking the clutch and cranking it? That would at least determine whether the problem is in the tranny.

hydraulic dipstick had no water. i thought that if the trans had water hydraulic would too? i didnt open the plug on the side to check inside of the trans.

As Funky says, water will find its way into manifold at the muffler junction. You cannot believe how much over a period of months.
I found that covering the whole hood with a tarp eliminates the problem.

Hyd dipstick sits a lot higher than the bottom of the tranny. Quick test for the tranny being froze is turning ther PTO shaft. If it doesn't turn, then you probably have water in the tranny. How much is hard to say. Someone with a better mind than me will have to help, but I don't think too many gears turn if the tractor is in neutral. Youcan also block the clutch to make sure it's forward of the flywheel. I agree with another post, if your not gonna start it, then best just letting it go without cranking it over.
