More progress on the Big Mo (PIC)

Moved the big Mo out of the shop for a little while today and got some pictures of it. Still missing the radiator and starter motor, both are being worked on this week, but as soon as they are back I am going to try and start her.

I have the turbo all installed the electrical still needs a few things, and I have to finish the paint job on the hood and put the decals on, but I think she will be ready for spring....

I also installed a kinda home made muffler in that big chrome pipe. I have a 3 1/2 inch pipe inside that thing with a bunch of holes in it to help knock down the noise. I am anxious to see if that works or not.

Just thought you guys would like an update. More to come, she is almost done.....

Here is an idea of what the charger set up looks like. I welded a plate on to the exhaust manifold for the charger and elbow, and cut a hole in the intake manifold and welded the end of it shut. The only thing I dont like is that the oil system is running at an angle because of the elbow I put on top of it and the way the oil return was routed. I will see how it does when I get it started, I may change that. I have some more pictures if you have questions. It really went on slick, I hope it works that well.

You can try running your axle and see what happens, I ran mine for about two years until I got tired of changing wheel bearings every 6 months. My 1855 would tear up wheel bearings, blow front tires, and the steering motor under the radiator is still very worn and does not steer well at road speed and leaks because of the abuse we put it through. I need to replace the entire steering box sometime. The heavier axle and bigger tires has helped a lot, but it still gets a lot of abuse. That hugger puts the weight further out in front of the tractor and that is even harder on the front axle. Plus plowing around in the mud and snow with a 2000# plus bale on the front in the winter trying to feed doesnt help it much either. I really need a 4x4 tractor to feed with. Hmmmmm I smell another project coming on..... Or maybe that is the smell of the skellitt heading my way....

Oh well.....

On my axle I put a 2255 axle tubes into the center axle housing on the 1855. DONT DO THIS, it doesnt work. The axle halves for the 2255 are about 1/4 of an inch larger round than the 1855s are and I had to have them lathed down. It really was not worth it to do this. I would probably look into putting an 8 bolt wheatland axle or the entire 2255 axle, bolster and all under your tractor.

Good luck

There should be a third slot by the hyd. levers, a little bit above if I remember right. You could add a control arm in there. Otherwise, the best way to go is a seperate 3 spool control just for the loader. Running off the remotes works, but there are better ways to do it. I never did like it when our loader was run off the rear remotes.

Remind me here in a few weeks if I forget.....

Here is what the muffler looks like. I shoved that up in the chrome pipe and welded them togeather at the bottom. They should both clamp to the manifold.

I just hope I dont have too much back pressure. I only drilled about 100 holes with the drill press for about an hour..... WHEW...

If this works I will have to go into business :-)

It was a neat idea, I guess I will see if it works or not.....

This is the true turbo ment for this engine. It was actually designed for the White 2-155 I think??? that had the same engine.

Putting a boost gauge on the intake side is almost a must in order to keep track of the turbo's health and engine performance. A pyro is a good idea as well. Keeps an eye on temps to preven turbo and related damage.

If you are worried about back pressure a boost gauge could be hooked up before the exhaust pipe to determine if and how back pressure you have.

Restrictiong the exhaust is a cheap and easy way of controlling boost, but as we all know it is not the most efficent way. However I have seen many engine that did not have a waste gate and functioned just fine. You may not even need one.
