  1. I used Rustoleum Proffesional series paint when I repainted my E9. After a good coat of primer, I used a light machine grey color which was close, but not exactly original, for the color of the block. A lighter color will let your oil leaks show more readily in order to trace down the problems. See my gallery to the left in my signature. There are some pictures of my E9 and my color coding when I had it out this past Fall. Remember to paint it pretty - that will make it go faster
  2. I've been running a propane injection system on my Ford F550 for years when I need the extra muscle. Too costly to run it full time and the extra power stripped out my stock clutch! I know that the propane acts as a catalyst to provide a more complete and energetic burn for the diesel but how does the hydrogen work? I've not heard of the hydrogen booster before this post. What websites did you find these units on? The propane system increases my fuel mileage but the extra cost of the propane precludes any monetary savings. I've learned to keep the propane injection throttled back a bit but the extra power is great for those big hills and short passing lanes! A couple hundred pounder propane tanks strapped on the back of my Mack would be great, but I could not stand to lose my E9 if something went wrong.
  3. I had another thought this morning. Now knowing about the internal stops and the types of adjustments required on these boxes, maybe someone had removed the pitman arm in the past and put it back together one or two notches over from the original position. That is if it is possible to reassemble it in the wrong position. This would account for full power all of the way to the right stops and an early loss of power towards the left if I am understanding the previous posts regarding how the mechanism works. With the low mileage on the truck, this would make the most sense to me and it would also be the easiest fix. Somehow, I'm not so sure Mr. Murphy and his laws would let this pass if he knows anything about it, but it is the first thing I will check. Thanks to all for your input.
  4. If your tranny has a basic 5 speed with the air shift rear compound on the stick with H-D-N-R as read left to right and the dash mounted front compound deep reduction then you likely have the TRTXL1070( 12 speed. That's what I've got in my RD. The front compound can only be used in the first gear but is good for D, H and R. I've never had a tranny that offered 5 speeds for the pto unit but is nice to have a selection! I don't know of any way to adjust the retarder, although I wish I could. If you have the E6-350 4v, there are some posts on how to turn up the fuel. You will need to do a search and make sure it is for the right pump. I did that to mine and it made quite a difference. You might also check that the puff limiter is working correctly or is removed so that it allows the rack to travel to the full fuel position. Watch your pyrometer and turbo pressure to make sure that you don't over do it and cook anything you don't want melted or scorched.
  5. The name that is cast into the steering box is R.H. Sheppard Co. from PA. I did not see a tag or number on the unit at this time. According to the build notes from the Mack Museum, it is a 245-2204 steering unit 592s Shep-pwr(integral). Where can I find service literature for this? I can likely do any repairs myself. I've done quite a bit with hydraulic systems but pictures and exploded views really help. I'm sure there is a specific set-up sequence to follow as well in order to get everything adjusted evenly.
  6. My RD822 has power steering and a massive single steering box. The power steering pump is gear driven and the reservoir is full. When I try to make a sharp turn to the left, loaded or unloaded, the last two turns of the wheel prior to the stops are very difficult. Steering to the stops on the right turns is a breeze. I'm afraid I will get dizzy if I have to make all right turns on every trip! What should I be looking for to fix this issue? The king pins took grease without problems, the truck only has 91k on it, I did not see any damage to any of the components on a visual inspection. I'm thinking it must be the hydraulics because it only happens when turning to the left and the engine speed does not make a difference to the effort required to get it to turn. My Superliner was like this sometimes but I always thought that was because I took up the slack in the steering box. I've not made any adjustments to the steering on the RD yet. If I can get the left turns as easy as the right turns, I'll be happy.
  7. I made some adjustments to the throttle linkage because the throw did not appear to be correct. At full pedal mash, the air cylinder did not bottom out the throttle arm. It was as if the air cylinder was not moving far enough. I also pulled the air throttle out and did some clean up and new o-rings on that part. It should be noted that the o-rings must be the correct size on the throttle body parts. I used what I had at the shop which was a tad overly thick and it caused the throttle to jump around alot due to the tight fit. The old part was reinstalled and that problem was solved. While it was in the shop, I tested the diaphram on the puff limiter. It was fine. All of that assembly was pulled apart and cleaned up as well. So, I made some other adjustments while I could see how it worked. Now, the throttle response is much snappier, it lets out just a little black-grey smoke and seems to run somewhat stronger. I turned the fuel up just a little but my turbo pressure still has not exceeded 22psi, but then again, my trailer is still empty for the road tests. The next equipment move should tell me more. I'm also going to post a question in steering & suspension regarding my power steering. It turns great to the right but it gets tight when turning to the left and will not go to the locks without extreme effort on the steering wheel.
  8. It's a 500 hp E9. Maybe I need to mount a 100 lb propane cylinder on the back end and put in the propane injection kit! The propane kit gave my F550 so much torque that it stripped out the stock clutch on a long hill! Propane makes a diesel much more fun to drive, that's for sure. I'll be pulling the truck into the shop today to check on the throttle linkage. I know the stop lever is set correctly from when I installed the motor. If the air linkage is working proper, I'll set the fuel up a little bit at a time until things look right by the numbers. I certainly don't need to worry about trashing this engine.
  9. The E9 manual I have is dated March 1993 but it shows a 3rd print date of November 2000 on the inside page. 5-102 is written on the lower right hand corner of the front cover. This is the OVERHAUL PROCEDURES book. Total page count is 186 numbered plus the index pages. I orded it from autorepairmanuals.biz for $29.95 + shipping. It is not an all inclusive manual. While it does cover most of the necessary material to work on this engine, it will not include anything about the clutch, detailed specs of the motor or any external accessories. It does have all of the required information for reworking the heads and rebuild information of the entire engine assembly. If you need to work on more than just the engine, you will need other books than this one.
  10. Yes, this is the RD that has the E9. My engine is running about 20-22 psi max boost. I have not seen the pyro get past 900 degrees. Both of these guages are brand new so they should be reliable. I'll have to check the throttle linkage this weekend when I can get an assistant, or cut a 2x4 to length between the seat and the throttle. What is meant by "both levers" on the throttle adjustment. As far as I know, there is only one servo on the left side that operates the throttle. I'm hoping that dropping that rocker arm assembly on #1 & #2 did not damage anything. It operated for 20-25 miles like that to limp on home. Other than bad fuel washing, I would not see it as too much of a problem. Without oxygen, the fuel should not have been able to ignite and as thin as the fuel is, it should have been able to bypass the rings. I was careful not to overheat anything on that trip home that night. Thanks for the input.
  11. Last night I found the link to the Eaton Clutch video. I forgot who posted it but many thanks. That's a great video regarding how to install and set up the clutch. I re-adjusted my clutch and rechecked everything this morning. All was set to spec, now. Bob-tailed it did not seem to slip. With the lowboy and 25k lbs it slipped a little and then was ok. I moved the trackhoe this evening (50k lbs + 20k lb trailer) and I could slip it a little in high gear but then it seemed to dry out and hold well when I had to climb a steep hill on a side road heading to my jobsite. The engine is still leaking oil, very badly. While I did not do a complete rebuild, just a valve job and head gaskets, I replaced the majority of the gaskets and oil hoses to prevent leaks. The liners still had light hone marks and few, if any, scratches. Everything looked really good inside the motor. Now, I still can't see where all the oil is coming from although it looks like the rivets at the draft tube connection might be the cause. When I had the engine out, I put in all new hoses in the valley and all new gaskets. The only other culprit could be the back of the injector pump. As far as the rest of the engine goes, I am not impressed with the E9 at all. I don't expect it to run as fast as my WRX but it is still lacking power. I've never seen any black smoke and I am wondering if the air throttle is fully opening the injection pump. On a long pull, the pyrometer has not exceed 900 degrees, empty or loaded. The smoke that does exit the stack is usually nearly white or light in color but never black. I don't know if this is the emission controlled throttle or lack of fuel. All new filters were installed so that should not be the cause. Does anyone have any suggestions on checking the air throttle? It acts as if it does not deliver full fuel flow when the pedal is on the floor, sometimes. The pedal will also make a funny sqeaking sound after crossing a rough area in the road, almost as if something in the air valve is loose or leaking. I think I miss the old cable rig on my E6. The E9 sounds like a freight train, which is cool. Now if I can get it to pull like one, I will be satisfied. When I pulled the trackhoe today, it was a little faster than the E6 but not by much and that's not good. My E6 was never over enthusiastic.
  12. Update: After cracking loose each injector line and listening to the difference in rpms, I determined it was #1 & #2 cylinders that were not operating. After pulling the right fender off and getting under the rocker cover, it was determined that the rocker arm assembly had come loose, jumped the push rods and snapped one of the bolts off with about 1/2" threads left in the head. I was lucky enough to get the remains out of the head with just a sharp punch and a small hammer. Some of the holes around the base of the mounts were less than perfect but a little file touch up put things back to a flat state. I found 3 leftover 7/16 grade 8 bolts from my previous exhaust re-work that were perfect. I used the least damaged old bolt to make up the fourth unit. A new o-ring, some oil and locktite and things are now back together. The motor sure sounds better but not as good as "killer" the pullin' rig! I must have missed torquing down those bolts on the rocker assembly during the re-build. I doubt there was any other way that they could have come loose in 50-60 miles. Other than a tiny chip out of the head next to the broken bolt, nothing was hurt but my backside from me kicking myself. I hope to road test it again tomorrow after I finish with the mirror installation. The next drag will be about 52-55k lbs when I move my trackhoe. After that, I have a D8 to move and that should be the real test. If the clutch is not slipping with either of those loads then things will be looking pretty good. I would still like to know what the factory's idea of run-in and retorque procedure is supposed to be. After the initial fire up, I let the engine run for about 30 minutes at 1200-1500 rpm with no load. I pulled it back in the shop and retorqued the next morning when everything was cooled back down. I don't know if this was the right way or not but there did seem to be a considerable amount of take up on the retorque.
  13. I've had head gaskets let go on other engines. They do not always make noise to let you know compression is lost, nor do they always leak into the coolant system. My plan is to start cracking injector pressures and using an infrared temp probe this AM to determine which cylinders are having a bad day. I've got a cylinder compression tester to check with after the preliminary test is done to see how bad things are. What is your definition of a "push tube"? Are you referring to a pushrod that operates between the lifters and the rockers? My liners spec'd out fine during pre-assembly measurements. Everything was re-assembled with care and done by the book. Even the torque wrench was new! The liners were not removed from the block. Only a valve job, new gaskets, seals and painting were done. Thanks for the input. Does anyone know if the retorque should be done with the engine hot or cold?
  14. Glad you liked it! I thought it might help next time I tried to explain something to the wife about an engine. Maybe I won't get such a blank stare back at me with that lost look. Now the leaks are easier to trace!
  15. I finally got the E9 all back together and cozy with the frame. The test driving bobtail was fine except that it was slipping the clutch a little due to the torque and maybe some errant grease or oil on the flywheel. The clutch was re-adjusted and I took it out to pick up some equipment with my lowboy. While the trailer was empty, I had no problems but after I loaded up with about 25k lbs of equipment, the ride home went real bad, really fast. I'm pretty sure a couple of head gaskets let loose as I lost a lot of power and it started running very rough. I made it home, but it was a slow ride. The only thing that I think may have gone wrong on my reassembly would have been the run-in and retorque procedure. I am a meticulous mechanic. I don't think that I missed anything on reassembly. The book was very vague regarding initial run-in procedures. My questions: 1) What is the correct run-in procedure before retorque of the heads? 2) Should the engine be hot or cold during retorque? I was so pissed with the whole deal that I parked the truck over the holiday week and left town. Now I have to face reality and get busy with it and determine if the head gaskets did go. If a simple retorque procedure can't fix the problem then I guess I will be yanking the motor out of the cradle, again I am not happy with the machine shop that did the valve job as they banged the heads around and left scratches that cross over the fire rings. I think this led to the problem. The block measured flat enough with the feeler gauges, as did the heads but both surfaces looked less than perfect. I think the motor had a bad gasket or two on it for a long time before I adopted it. Any suggestion besides finding another heart for the patient would be appreciated.
