I need the help of house members in this matter.
I have a year 2000 Honda Shuttle 2.3 i ES, 4 cylinders.
In September, the Crank Pulley came off.

Mechanic found the pulley was cracked and the pin was bent.
Another pulley + pin was installed.
Problem happened again about 3 weeks later. Another pulley installed.

About 3 weeks ago, it happened again for the 3rd time and we decided to investigate the cause.
Mechanic said the crankshaft was cracked and suggested buying another engine.
He also said the crack could be filled by a welder.
Filling was done with the assurance we won't have any more problem as it was done well.

Well, just driving the car around town for shopping and errands only, the pulley came off again barely a month after.
Some say replacing the crankshaft will bring more problems.
The car has mileage of a little over 200, 000 and drives good.

Now my questions:
(1) What is the cause of this problem?

(2) Should I replace the crankshaft or buy 1/2 engine?

(3) What other Honda vehicles have crankshafts and engines that are compatible with my Honda Shuttle?
This is in case I don't find the exact model for my car in the market.

(4) Is it true that replacing the crankshaft will cause more problems?

(5) Any idea how much the crankshaft and 1/2 engine sell in the market.

I will be sure to read every opinion. And thanks for reading this.

P/S: Please, by "pulley", I mean the meta disc that locks the crankshaft in place before the tire is installed.
That was what the mechanic called it, but I found out is also called the "Harmonic Balancer."

Pics of the problem please. What material is the pulley made of?

I do not have any pics and I am currently away from the car.
I get the sense that by pulley, you are referring to the drive belt that turns the power steering and fan around.
The mechanic called it pulley but I think he was referring to the metallic disc (I found out it is also called "harmonic balancer" that locks the crankshaft in place before installing the tire.

Hope this helps and thanks for your time.

Pls, buy another engine, don't buy pulley and pin again. I have a 98 civic, a wonderful car. I changed the pulley more than ten times, two crank shafts and lot of stress. I had to change the engine last month. The money I had spent changing those stuffs couple with stress could buy 3 engines.

Thanks a lot for your input.
Another engine sounds convincing given your experience.
Do you have any idea about cost and Honda models that are also compatible?

To me based strictly what was written leads me to believe that you have an unbalanced crankshaft. Did the mechanic consider a bad harmonic balance? https://en.wikipedia.org/wiki/Harmonic_balancer

I'm certain that a properly sourced crankshaft will sort the issue but you have to balance the economics of that versus getting a new engine in the Nigerian sphere.

Good luck.

@ op, I don't have idea of the price. contact luvinhubby here or gazzuzz. Good luck.

The harmonic balancer is what we have been replacing.
Maybe due to the imbalance in forces, the c/shaft got cracked.
I agree with you that a proper c/shaft installed by a good mechanic should solve the problem.
Still chewing on my options...
Thanks

If you want to end your problem, buy a clean ENGINE that has never been opened. If you are the type that enjoys visiting mechanic you can as well

Majority opinion seems to favour replacing the engine.
Any idea of the cost and Honda models that have engines that can fit?
Thanks.

You want to replace a complete engine cause of harmonic balancer?

If you are in lagos bring the vehicle, I'll replace the crankshaft if necessary and balancer and give you a 10,000km guarantee on the job.

Unfortunately I am not in any of these cities.
Still meditating on options.

Budget 140K

Wow!
That's lot of money.
Or are you referring to a brand new OEM engine?
Thanks

Laughs.

I doubt your engine is more than 70k.

My mechanic was looking at a figure of 75K.
