low power on 93

[Greenleaf]

But if you get a stubborn dirty threaded stud, you'll be there for awhile.

BOY... ... ... ..... HOWDY!!! #@$%!



FWIW, there are tons o folks out there that simply don't know there is a nut under the pump. Its quite concealed.

 

[btoscano]

Harbor Freight has Metric S-wrenches.



They're cheaper and do the job. In fact, if you try to adjust the pump timing later, they work better than the SP144 for the top back nut because the fuel supply line gets in the way of the SP144 if you don't remove it. R/R the pump that would not be an issue since you can remove the fuel line first.

Crap... looks like they discontinued the metric set. Here is the link that used to have them on their site: http://www.harborfreight.com/cpi/ctaf/displayitem. taf?Itemnumber=5124



By the looks of the link the item number is 5124. I would call your nearest HF or even the website number and see if you can find a set before they're gone. That 13mm "S" wrench fits the hidden nut like a glove. I've found the rest of the set work well in other areas and on my Toyota too.

 

[backroad]

Harbor Freight Co. calls the METRIC S Wrenches discontinued, but the stores in Phoenix have them in stock,(one of them has eleven sets)..... However, they do not ship out of the stores, and I'm about 100 miles from any of them...

 

[ARhine]

I already have both the metric and standar sets. Got them on sale. The 1/2 fits 13mm stuff better anyway on my set. The 13 is kinda sloppy.

Little bit of excitement to the project. Went out to the shed to get it yeserday and it wasn't there. Call the cops and all that jazz I had never been through before. Have all kinds of thoughts about not seing it again or it being junked when I do.



Sherifs office called a little while ago and said it had been found parked in small town 120 iles from here and in good condition. They said everything looked to be there. Hope my Miller welder/generator is still in the back.



I live in a very rural area and have never taken they keys out of vehicles in my yard in 18 years, guess I might have to start now... times are changing I guess.

 

[dpuckett]

Maybe it dont run so bad after all. Glad you got it back in 1 piece. I am going to have to start remembering to take the keys out of my pickup. There seem to be more people deciding they need our CTD Rams more than the legal owners.

This makes me feel better about the truck now since I got it back and didn't loose it.



I have to get it in the shop and take it appart so nobody can steal it Going to pull the trans and transfer case to rebuild. Also will probably pull the injection pump and injectors and send them in for a checkup. I am going to end up spending about 1/4 of the trucks purchase price on repairs over this past year, but after that it is hopefully good to go for another 200K.

Maybe the new owner was as unimpressed with the power as you are!

Just kidding, good you got it back.

Had some nice cool weather for a welcome change so I worked on it for a few hours tonight.



Checked the valve clearances and everything was in spec like it had been done fairly recently.



Made another plug and did some pressure checks. Put a plug with a pressure guage and a valve stem in the first boost boot that would connect to the elbow at the turbo. Put a second plug at a the boost boot disconnected at the intake air horn.

Ran it up to 15psi and it took 1 minute to drop 1psi, there was a small pinhole leak bubling at one of my plugs.

Connected the one boost boot back to the engine and got it turned to minimize valve overlap as best I could. Pressureized it up to 20psi and sprayed the intake all over, the line to the AFC, and air horn. No bubbles anywhere.



What next? About the last check I can do here is the base timing. Past that having the injectors sent in and tested is my best bet I guess?



EDIT: One other little thing I noticed. Under the hood I was holding the RPMs up around 2K and listening to the pump. I noticed that the engine has a slight fluttery sound to the rpms. It does not register on the tach, but if you are under the hood you can notice it. Anything?

 

[ARhine]

BTT. Anybody?



Anybody just wanna buy the whole truck

 

[Greenleaf]

I notice a fluttery sound on my 92. It's very noticable. However the truck produces more power with the factory auto transmission than I would ever be able to use and everything seems to operate perfectly.



The injection pump was replaced along with the injectors.



The 90 has the the OEM pump and injectors @ 310500 miles and it runs very rough/shakes etc. etc. at slow idle speed (800 rpm) However it too has much more power than I could ever hope to use on any given day and again things seem to operate just fine.



I think your truck is hexed.

 

[ARhine]

I am beginning to agree with you.



There is a nice V10 truck for sale with alot less miles on it for dirt cheap here in town, has me tempted.

 

[Greenleaf]

In all seriousness... I don't there is any mystery. If you want to pull that trailer of yours over the hills in Colorado you are going to need to vest some $$ into that thing.



First a real turbo. More than the popular modified HX-35. You need cool air flow THROUGH the cylinder head. Possible twins. Depends on how YOU tow.



An open exhaust system. 3. 5 inch or larger.



Injectors to develop the HP



More pump mods than truning the cone to the deepest setting and moving the fuel screw into the lock collar. That ain't nothing. You may be looking at only 200 hp or so.



A clutch to hold it to the ground.



Sounds like a rebuild on the 5 speed if your serious about the noise.



A full gauge set including coolant temp and fuel supply pressure.



A piston lift pump depending upon how much HP you want and how long you hold that kind of power up the hills. (starve the injection pump for fuel long and you'll be walking some day)



Radiator in top shape or a new one to be safe along with a new fan clutch.



Three piece manifold to prevent a blown gasket and loss of boost/power. (with more power comes heat)



Unless I missed something and am way off base here... ... ... ... ... ... ... I don't think you have any mystery at all. These engines are 160 hp and take some time/$$ to perform to potential. They are not a 305 hp engine out of the box.

So stock these cant pull as good as a 350 chevy?



I am not mad at you are anybody here so don't take it the wrong way. I am just mad a myself for spending alot of cash and having no gain from it.

 

[Greenleaf]

I connot answer that. I pulled a full sized farm tractor to Waterloo with a 350 chevy and it worked really well. I have not pulled that same tractor with a stock 160 hp Cummins to know.



I believe that these engine must be modified systematical like and you will not waste your money. I don't know what all you have done as I have not read every post in this thread.



If you have wasted some money, we could probably help you straighten some things out so that you do see substantial gain.



I hope the abpove tips I posted assist you in understanding what needs must be addressed to gain top performance.

From a dead stop, mine could barely pull itself up a hill in my neighborhood when stock. :-laf



Now I don't dare put the throttle down all the way while towing my 5k trailer... it's just too much power and I never need it all. Oo.



I would say they probably don't pull as well as a 350 when stock, but with a few cheap and easy mods they will out-pull one all day long and get double the MPG doing it too. Try modding a 350 to get 700lbs/torque and see what it does to the mileage and engine life while towing.



EDIT TO ADD: You mentioned EGT's of 1200*, which aren't too bad for higher elevations while towing. What EGT's are you seeing for an absolute maximum?

 

[ARhine]

Thank you, those were the two answers I have been looking for. I just thought I had a bum truck from everybody elses comments on this board. At least I have tested and checked everything on the truck now



I have a bearing kit for the getrag bought already and want to get it dropped out in the next month. That is 1st on the list.



Next what do I do to make it pull. My goal: I was planning on buying a 26" gooseneck, put a slide-in pickup camper on the front of the trailer, and put my jeep on the back. The new offroading rig will weigh in at around 5500lbs, camper most likely 800-1000? (really haven't checked on that yet), + the weight of the trailer. Sound feasable to use this truck for that purpose, or should I get out now?



I would be very happy right now to be able to tow like my dads stock 02. It is the standard output engine. It has no problems pulling a stock trailer loaded to 20K lbs down the highway easier than I pull 5K.



All my mods are in the sig, they money I spent was buying the truck and not having it pull as well as the $750 truck I had at home.



How much money in upgrades is this gonna cost, gotta put that in the budget. Sounds like it is harder to get the power to where you can use it if you use the truck for pulling a load. The guys who just play with their trucks don't seem to have to worry as much about EGTs.



JRussel:

In colorado I don't know where the EGTs would have stopped at. I would drop to 4th and get my rpms up on the govenor before hitting the climb keeping out of the trottle as much as possible. After a mile or so I had to start lifting my foot at 1250EGT, once it was pulled down below 1700 rpm I would goto 3rd and it would stay at 2300rpm, 35mph, 1000-1100 EGT and there it stayed until I found some downhill stretch.

Here in KS there are several hills on HWY36 I drive that can make it hit 1250 and pull my speed down below 50mph if I don't shift down. Usually now I just drop it to 4th when the speed gets under 60mph.

There was significant differences in trucks when the first genners rolled off the assembly line. My truck when completely stock would defenatly out pull a newer 350 equipped truck. Mine however I feel was a stronger one from the factory. I could pull a 36' gooseneck with two fullsize trucks on it, better then a friend with a 350, 25' gooseneck and 1 fullsize 4X4. Bgilberts old grey beast put down more hp to the ground then what it was rated at the flywheel when it was stock. However some were doggy too. I will admit that my truck never had gauges on it stock, and I even ran it quite some time with no gauges after I changed the pump enough to get a haze out the exhaust at full power pull. My engine temps would get hot, but would not peg the gauge. With stock size tires, and stock pump, and 5k load, it should pull OD all the time. Mine did stock. About the only reason I changed my pump settings, I went to 33" tall tire with 3. 55 gears, then it would run like yours does power wise. A little fuel screw adjust, then it was off to the races again.



As far as what's wrong with yours? I haven't a clue. I will go back and read all the posts... ... ... I think you need to get the injection pump looked at, and upgrade the lift pump. Pull the injectors and have them checked.



I would not go as far as Scott mentioned above. There is still something wrong with your truck. Boost is low. I suppose something could be wrong with your turbo, but not likely. Does the wheel rub the housing? Can you make it touch the housing? If not, and there is no endplay the charger is good. Do a mapquest and see how far you are from Lenox, Iowa. My folks live there and could meet you on a weekend later this summer. Then mapquest Fairfield Ia, thats where I live. My life is pretty full and will be until January, or I would come out there. If you have any free time, I'd like to help you, at least verify your truck is doggy. You are more then welcome to come out on a weekend, stay here. Let me know. Open your weekend up for October 8th, and follow me to Peru, its about 7-8 hr drive from my house, you could sleep here, on the way.

Looks like about 220 miles

I can't make the turbines hit the housing, there are about twothickneses of notebook paper in between (could't find the feeler guage that day)
