Installing a 3JH4E *^%#! Yanmar (Rant)

[shakey doug]

G'day,

Crack each injector in turn if reaction found swap injector position to confirm it could also be a bad pump element or delivery valve causing problem. This problem has not been monopolized Yanmar.

Well, I cracked each nut and the motor slows the same on each one of them. I just wanted to make sure that it didn't have a dead cyl.

So, I'm off to the San Juan Islands tomorrow to run the piss out of it. I'll just plan on putting in a Pythondrive this winter. Another b.o.a.t. token.

del just another thought how do you know your g/box input shaft and engine fly wheel are aligned i know on my engine when i have replaced the damper drive plate i have to also put in a dummy shaft and then bolt up damper plate to fly wheel before fitting g/box

Maybe you can find another similar Yanmar and watch it run to see if your shaking problem is unique to your engine and mounts....

Del, I have been thinking about that spacer you installed. Without the flex coupling in the drive line you are liable to damage the drive shaft with all the side motion you have. Especially every time the prop shaft hits the side it will put stress on the shaft at the coupling. It is likely to cause stress cracks just behind your coupling.

Here are some pictures. With the shaft pulled back you can see where the shaft was slapping the stern tube.
It had even cracked the fairing around the strut.

I sent out the prop to have it balanced and no change.

So, I bit the bullet and here it is. It runs so smooth I can hardly hear it run

The shaft turns perfectly straight and the damn motor can jump around all it wants now. And, the PSS should last a long time, as well.

I had to move the motor 3" forward to accommodate the CV drive and build/mount the bracket to hold it all. Now I just have to modify the enclosure to fit around the front of the motor.

We expected nothing less the a steller Job Del...Nice work..

PS: Did you find your tongs?

Why would you want to cover that up? It's beautiful!! That's art.

Yep! Got'm.

Are you in the water yet? I'm going to launch this Wed/Thurs and spend the rest of the nice weather out (if I can ).

I need to keep the heat from migrating into the solon. Maybe I can put it behind glass.

Is that red towel in the back where the exhaust goes through the bulkhead for chafe?

As usual Del a fine job.

NOooo! It just happens to be hanging there after the clean up, the sponge too. Gaa!

The exhaust has a foam strip under it and that's what it's hang onto.

Well, it might scare the ladies now but long about November when the Salon is the Saloon you could exhibit it-- your buddies will think it's great. Hope you get Trix out and give her a good run. We ought to get some good sailing as the fall fronts start to come. You deserve it after all that work to kill that problem.
I think I learned something from your solution. I want to try something similar.

I'll take credit for the Python drive idea if it works! Besides it was his money!

Nice work Del. Looking forward to hearing how it works.

Isn't there an old saying about "not trusting a sailor with a clean bilge"?
