Custom Girdle/Cummins

Why do you need a 1 piece girdle???
We use a 3/4" girdle with ground blocks between the caps and girdle on the tractor with zero problems. And it has a touch more load on the bottom end than any 5.9 :evil
I plan on putting a 13mm w F/C DV's hurting on a 12V for P/S:evil
 
there are motors running alot more than a 13mm p pump with just a modified cummins bedplate (haisley motors)

kennys machine makes a thicker girdle that requires you to machine down the caps and is much thicker than the cummins piece but I know of none that incorporate the caps. the billet block girdle was also a 4 bolt main girdle block setup.

and as distributer said his diesel super stock sees more cylinder pressure and makes more power than any 5.9 ever has with just a standard girdle.

Doug is a good guy. When I was working at woodruff he was very cool to work around. Also know ALOT about these trucks. Josh always said if you got doug in the right mood you could see how much he knows. Had a chance to see it and Doug is really good.

As for the pump/accessories and girdle. I don't think you need it either. A two piece will turn you just fine. Heck some of the guys running sigmas are still running a deck plate/girlde with spacers between the caps and girlde. I know this for a fact cause I had to help Josh rush one for a puller last year. He never had problems with it either. The only way you need the girlde is if you have extremely high cylinder pressures, which with 13mm pumps I don't see that happening, or if you running extremely high RPMs, like over 6k. That when you got to worry about that crank walking on ya. Before that you really don't see it too much.... Too much...
 
i dont really see a need for it, kent doesnt run one on his truck, i know where a built motor is from scheid that saw 5000 all season and it doesnt have one. we pulled the pan off of it and the bearings looked new. scheid claims that the blocks are strong enough that you dont need to run one. i would put the 14mm studs in it and a set of coated bearings and go for it. maybe disturbed will chime in on this. he has some picks of his motor if you guys need to see it to believe it.
 
One that looks like this?

That is the most awesome thing I have ever seen! Lol If I was going to build an engine on a stand with all the goodies I would deffinately use a girdle like that one.
 
Ok heres my question......

My girdle looks exactly like the one in the pics, but i dont see how the studs can come up through the plate. On mine there is atleast a 1/2" gap between the main caps and the girdle.....maybe Im just looking at it weird

Your girdle isn't 1/2" thick is it? I imagine yours is the stock cummins block stiffner.
 
Just give Woodruff a call. Josh is always willing to help someone design and build. Im sure they can come up with what you want.

The Cummins stiffener isn't the same as a girdle? Whats the difference then... I was going to get a block stiffener soon myself.
 
Im thinking of taking the stiffener and having my buddy do a little fab work and get it to tie into the main caps...should be pretty easy, but maybe a bit over kill.

Ill be running the block stifener and 12mm main studs and only turning 4800 max.

I wouldn't say 5000 rpms absolutely need it. As I said, over 6 and very few people even see that. The main problem you going to run into is spikes. If you get an rpms spike from load to no laod to load, say when hoping, the crank has a good chance to walk. Not saying it will but it could alot earier. Whether or not a specific engine will rev up that high is another question all in itself.
 
I thought of going with one of the ones that just goes around the oil pan rail I plan to see 5500 launch but only 5000 down the track, to me it seems that huge cyilnder pressure would cause the crank to "Shimmy" or distort or however you would like to call it. Anybody have any advice as to if my application would benifit from one of the oil pan rail ones that does not incorparate the mains?
