Hydrolocked engine

Post by Connito » Wed Jul 31, 2013 3:02 pm

Hello all,

I tried to search for a similar thread, but I couldn't find one. I have 2002 Ural Tourist and I hydrolocked the engine! :( I should have known better, but...
I haven't taken it apart just yet, but I was wondering what would you think I need to replace on the engine. I would like to purchase the necessary parts, or at least the ones that I know I must, beforehand. I know I should buy Pushrods from modtop. What else do you think I would need? I surely hope that the crankshaft is fine.

Thank you in advance for your thoughts and suggestions,
Pete

You won't know until you tear it apart and do a thorough inspection.

Maybe you can describe what you did to discover it was hydrolocked and any other info you have. You may also want to let us know your location.

Thanks for your reply. What is there to describe... The float needle failed and I didn't shut off the petcock (because it was only for couple of hours, not over night, which proved to be very stupid thinking), so the gas went into the cylinder, I hit the starter and all I heard was a bug BAM. Now the engine doesn't spin. I am still very mad at myself for not shutting off the petcock, or not kicking the engine first. Although, in my defense there were no signs of gas leaking and I really left it for couple of hours only. I am in Boston and with the help of coupe of friends, I will take the engine out on August 24th. This is why I wanted to buy as much parts as I can prior to that.

Cheers,
Pete

Have you pulled the spark plugs and try to turn the engine over using the kick starter>

You may want to consider pricing out a used or rebuilt late model engine instead of sourcing parts.

I wouldn't buy a used engine. I have done so in the past and I was very sorry. A rebuilt later model engine would be out of my price range, unfortunately. I have considered replacing the engine with an R BMW one, but this is also something I can't afford.

Thanks for your suggestions and taking the time to reply!

The motor won't turn over by foot even with the plugs removed? Hard to imagine you did that much damage with the starter.

Have you made sure the starter was able to disengage? Pull the starter to check and make sure it is free. Easy job. It is possible that the starter is still engaged and due to the pressure is unable to release from the flywheel.

Can't really imagine what else could have been damaged that quickly that would have locked up the engine.

Ural's are pretty easy to pull the heads and cylinder off of and check things out though.

.
I'm thinking along the same line. Ingesting water into a running motor during a water crossing could bend a rod etc but I wouldn't be buying any parts till you find the problem. A bent push rod isn't going to keep the motor from rolling over. I also find it hard to believe you could do major damage like bending a connecting rod with just the starter. Not saying it couldn't happen, I just find that hard to accept. I'd expect an electrical meltdown in the starting circuit before bending any major hard parts with the stock starter. Good idea to pull the jugs and and the starter to have a look see before buying parts or looking for a motor swap. I wouldn't go into the panic mode just yet.

Have to agree with previous comments...no need to buy parts until you find source of problem.

I hate to tell you folks...but if you E-start a hydro-locked [edit: Ural] engine you are going to bend the sh!t out of something [how bad depends on how much fluid is in cylinder(s)]. There is a lot of torque in that starter. It has to spin a pretty heavy flywheel. Bending bits and pieces to the point of seizing the engine is easy. ALWAYS kick it through first. ALWAYS.

Even if you can get it to run and all seems good...it will "show" you (i.e. break down) what you phucked up within a month it you put very many miles out it.

Lesson learned. Maybe. :twisted:

I'm not saying you are wrong by any means, but I've seen hydolocked car engines that did no damage by trying the starter. At least a Ural battery won't supply as much power as a large car battery.
