no, one drops down in the center so on the opposite side it hits the cross member and the other has a long stem out the back that runs past the hydro pump when switched. The passenger side hummer manifold can be used on both sides, however, on the passenger side the glow plug tabs have to be...

just to add the info here in this thread just in case it makes the stickies. I have posted in:http://www.steelsoldiers.com/showthread.php?159215-optimizer-long-block-hummer-24V-or-cucv-24v The optimizer was being cast by Navistar for GEP up to appox. 2013. They have switched and now use...

There is an extra port with a plug in it on the water pump, you don't have a port on the cross over unless you change the cross over. Oil pressure can be done from sampling port or by putting a T where the existing sending unit is and adding the second sending unit. just need some small...

Any non bead lock rim these tires can pop off the rim. most of the time it is because the try to run low pressure and do not have bead locks. The tires were made for bead locks but will normally stay on a regular rim under normal use and regular full pressure. If it were me, I would not...

with the truck off you should have over 24 volts at the back battery. I think you have a bad rear battery and bad passenger side alt. if the battery were good you would get 24volts on back battery with truck off. your second alt was probably taken out by the bad back battery. I would by two...

yes, I actually know where the guy lives since he runs his web strore out of his house. The reason I went with him was due to being local. It does not matter how big a shop someone has if I can't go see them. attached is a pic of the casting marks, these match my motor. it is the backwards D...

it will work if the terminals are isolated from the case. depending on the amp rating will determine how long it last. If you have continuity between any of the terminal and the mounting feet then it will not work. If it is isolated it will work.

New info has now been made available: Leroy diesel has been very helpful in tracking down the issue. GEP no longer uses Navistar for their castings. They stopped about 2 years ago. They now use Dalton which appears to be a quality US foundry. This change was made by GEP and they did not...

I have an eaton e locker and yes any front locker makes the truck awesome. I thought all of the parts in the diff were heat treated and thus not good to weld on but I don't know it all. please reply to this thread when it fails, I will hold out on any judgement till then. keep an eye on...

just an update - I am still in a holding pattern with the new motor. At this time, GEP cannot even tell me what markings should be on the block. They believe it should have the Navistar logo but cannot confirm. Per their knowledge, if it has changed it is a recent change. My only contact is...

look at the short drivers side hummer manifold. it has a vband clamp in the end. It can be put on passenger side so it faces forward. you can use the stock drivers side, build cross over to come to the front of the motor and up past the drivers cross over will have branch to second manifold...

I picked up my 6.5 gep today. the motor looks great however I am currently not completely satisfied until I talk to AMG or someone early next week. The block is definitely new it is a 506 casting but I cannot find a Navistar logo on it. Also no marking on the heads. I at this time cannot...

look for boiler drains not faucets. It may help your search. most boiler drain's are pipe threaded one side and hose connection on other. Rich

just going to add a little more info on the jump start of a cucv with damaged batteries. The front battery is all that is required to keep the truck running. Even with the 12v alt not working it will run on the battery for quite some time if you limit all other 12 volt power. once the truck...

stock pump and gasket it comes with is what you need nothing special for military. The push rod will probably fall out. put some wheel bearing grease on it, just enough to make it stick in there and it will help in getting the new one installed. consider the electric fuel pump install if you...

I think your pump is bad. They will move fuel when there is no pressure but wont pressure up. so when you remove the line coming out it pumps and looks to be good but as soon as it needs to push pressure it quits. go ahead and get new filter cheap insurance. todays mechanical pumps made in...

please post up the alt info if it works. I am still stuck with going back with all the cucv stuff for now but eventually will get to the serp system once it is all ironed out and I can get the parts. Thanks Rich

I am supposed to pick it up tomorrow. It is in Houston. I will be taking pictures and posting it. I will try to get pics of what you need if not, stop by anytime. I don't have to be there. I can have my dad open the barn for you. Thanks Rich

yes it only supplies the glow plugs. If the glow plugs were added to the 12 volt circuit with a low or dead front battery, even with slave cables connected, there is not enough 12 volt power that will immediately come from the front battery to power everything, The voltage would be to low due...

what was your solution on the cs130 isolated ground. did you have to buy the expensive marine one discussed in previous post? motor looks great.
