Replacing Water Pump Honda Ballade 150i

Spray it liberally with WD40 or some other type of penetrating oil and let it set for an hour or so then try again.

What Nut size is it ?

the following link may help if not there is one other meathod i have up my sleave but it is a last resort method and can be dangerous so please try other methods first, and get back to me/us

I don't know how much time you want to spend on this project. You may want to look into just getting a new pulley and nut, throw it on your new water pump and be done with it.

I guess the crank nut does have to be removed. Here is a real nice link for you, you may have to invest in a breaker bar, if you don't already have one or a long piece of pipe. Also, if you haven't changed the timing belt in a while, this would be a good time to do that also.

If you can do it without setting the Ballade on fire, heat the nut with a propane torch for about 3-5 minutes. Not too hot, but hot enough to expand the nut. Then it will come right off.

Caution, don't apply too much heat or you may melt the shaft seal. This would be rare, but possible.

Spray the crank bolt and crank snout with some good penetrating oil and then give it a few raps with a hammer to work the oil into the connection. Now determine which direction the engine spins. Get a good 6 point socket on the bolt head and an extension just long enough to clear the end of the pulleys. Now get a good breaker bar, and wedge it against the frame, and rotate the engine in the direction it spins until you have jammed the breaker bar against the frame, or engine cross-member. A rope will hold it there for the next step. Now go hit the starter. And again, and again until the engine spins freely. Usually it comes loose on first try, occasionally 2-3 tries. This should only be done with a 1/2" drive socket set, and only after giving up on impact guns. Good luck.

WARNING! Keep all people away from the area. A broken socket or other part will be under great stress.

Elmo think this through, OK bob c?

Elmo locate 6 point socket (because 12 point probly not strong enough) over frozen nut. Then Elmo fix about a 3 foot 'cheater bar' to socket. Then, Elmo rotate pump pulley until cheater bar jams up against the frame somewhere... Elmo thinks he has just made sort of an immovable object.

Now you say Elmo get into car and turn ignition key... this will make engine go round and round. Elmo sort of thinks of that as irresistible force...

So to make sure Elmo has it straight... immovable object at rest in car, irrestible force ready in car, and Elmo in car... and then you want Elmo to...

Elmo want to know... is that the best thing you can come up with bob c? How about peterg7lyq?

Its crude but it works, the reason for using it is room is restricted in front of the engine, if not impact driver is best option

That little electric motor we use to start our cars is a very strong thing, and the gear reduction on a starter is also very steep. This combination provides more torque than that bolt is tightened with. It would be great if the engine was bolted to a bench, or an engine stand, and the engine was locked from rotating. Then one would only need to place a sufficiently long breaker bar on the bolt, and you would be strong enough to back the bolt out.

WAKE UP SLEEPING BEUTY, THIS AINT NO FAIRY TALE. THIS IS THE REAL WORLD.

The Honda engine crankshaft hangs just about 2 inches above the inner fender. That fender does not move. That means that you would have to drop the engine 2 inches lower than it is mounted to be able to use any impact on it. The pulley on the Honda is about 4 inched deep. That means that you also need an extension on the impact. And if the impact has enough intestinal fortitude to overcome the extension, the engine will probobly start to turn over.

Oh by the way, the customer is not willing to pay any more than shop labor time.

Have a sunsational day!!!!!!!!!!!

Good morning bob.

My little friend Elmo was pointing out his belief that the technique described sounds a little dangerous, and might not be for the timid or mechanically un-inclined. Also as has been discussed, this is sort of a last ditch effort, but will almost certainly work... with the proviso of correct combination of the hand of thread and rotation of engine. If this combination is incorrect, we will see that demonstration of irresistible force vs. immovable object.

Our Guest poster has not commented further that OP... I see no reference of any kind to price tolerance the OP may or may not have for any part of this project.

Thanks, bob. Hoping for a sunsational day for us all!
