The Fun Begins

Jack,

How does the Kck-down Modulotor ( i think that is the right name) on your tranny work. Mine has a linkage from the engine throttle with a box on the outside for adjustment where it goes to the tranny. I have a chronic leak there that I would like to fix. It leaks mostly there when it is sitting.

I have replaced the oring a couple times and that worked fro a little while and came back.

Looks like you just have wire coming out there.

Lookin' good Jack! How long do you expect it to stay that clean?

I am in the process of designing an automatic engine washdown system especially for DD engines. It will spray Simple Green all over the engine and compartment, then wash down with high pressure water. It will have sensors so that it will only work when the engine is warm and only when underway, so that you don't mess up the driveway.

What do you think?

I'm thinking the soccer mom in the white mini-van behind you is going to be just a wee bit annoyed...but not NEARLY as annoyed as the HP officer on the motorcycle!

Jack,
Where is your alternator/generator?
Just wondering how you plan to charge your batteries.
Looks great....

We plan to use a smaller 24 volt belt driven "truck type" alternator instead of that great big (heavy) 50 DN. The only thing on our bus that is still 24 volts is the engine ((starter, engine stop, fast idle, && emergency stop solenoids). Anyone need a 50 DN? Jack

The wires you see are the neutral start switch. The kickdown modulator is the small brass fitting to the rightr of the neutral switch. The modulator is air operated (off the air throttle). I do not know if the mechanical modulator has an internal seal around the moving part as well as the O ring around the outer part of the modulator? When replacing the Oring, lubricate it first to help prevent cutting it when installing. Jack

Jack,

I see that you connected your breathers coming from your valve covers.

I found my 8V71 was not resistant to any back pressure. This was after talking with some 2 cycle experts and a lot of trial and error of connecting the 2 lines, building a large breather, etc. Even a small back pressure, produced larger oil leakage.

A fresh engine may make a difference for you.

The engine is back in, all the hoses have been reconnected, all fluids and filters have been replaced, and most of the wiring is reconnected. The bracket has been fabricated and the new 24 volt alternator has been installed. So, hopefully, tomorrow morning, I will connect the battery and starter cables and we will hear that sweeeet 2 stroke DD sound. Jack

Love the pics and all the details involved. Now you have most of us as excited as you are to hear that first sound! thanks Jack. Later

LOVE THE PICTURES!!

This may be a dumb question, but that alternator is setup to rotate in the correct direction, Right?
Looking real good Jack. We're excited for you. Will & Wife

Alternators will work spinning either direction. The only concern is that the cooling fins are "tipped" the right direction or are straight. Jack

Jack,

Great job, what would you estimate the hours you have in the change out,

Thanks

John

That looks really nice. Good work.

God bless,

John

Looks Great Jack!!!!

One question, It may be an optical illusion in the lower picture, but is the red hose(fuel line) rubbing on that pulley at the at the back of the bus right hand side as you are looking at it?

poppi · April 07, 2009, 07:54:19 AM

Oh boy oh boy is it running yet?
They always look so nice when the engine is put back in.

Any reason why or why not you didn't wrap the exhaust cross over pipe when you had it out?

Thanks for the pictures
