If you tell me what to look closely at for you I would make a trip to see it for you and take either pics and or video as I am roughly an hour from there if this would help. You can reach me at 570-724-5004 thanx, Dennis

Luv them BULLDOGS!!!!!!!!!!!!! Legged or wheeled, either will work well with me.

This is a complete 5 volume set, so please keep in mind they weigh up pretty quick as far as shipping. Each set has the complete Mack Binder. This set covers CH, CL, R, RD and others from the mid 80's thru 1997 with motors 300 thru the V-8 they cover absolutely all aspects from front to back and top to bottom including sleepers and trim. I will sell these outright for $325 and you pick them up or I will trade with a $ difference if you have the same syle comprehesive manual set that will cover my 2002 RD 688 with the E7 350. Please keep in mind the shipping will add up quick as this manual set is HEAVY!

Fuel pressure was confirmed by Mack Dealer to be within range. Dealer refllashed computer to VIN specs. The mechanic stated with cut out test that cylinder #3 made a slight difference but not enough to account for the issue. His remark was that the problem was like a ghost in that it was nothing definite. The injectors were all installed correctly, however the one as I stated the groove midway down the injector had a slightly smaller groove width in that it squeezed the o ring slighly more than the others. I stuck that one in cylinder 5 to ensure I could remember where it went, in case of needing to pull it again.

If you have enough to go around I may consider

Looking for a left hand 55 gallon fuel tank for my Rd 688. Will sell the large tank on my truck once I have replaced it, so if anyone has an intrest let me know.

Oil pretty much went everywhere you didn't want it to. Everthing thing was taken apart and cleaned out good, air to air, etc. Plan on trying another cut out test to see if I can yet identify which cylinder. The only thing I noticed with the last four injectors that were replaced is that one of the center o ring grooves on the new injectors appeared to have a smaller, tighter groove for the o ring and you could tell it sqeezed the o ring more than the other 3. Another question I have would be; how important is it to consistently use Lucas or a like product for lubricity in todays ULSD Fuel? Sometimes I add some and sometimes I do not.

I am new to this site and am hopeful to find some good mechanical help. Bought this one owner truck 2 years ago and ran with only minor issues. Currently has 321,000 miles on it. Did an extensive maintenance upgrade to it this past spring. (none having to do with the engine) My motor issues started thereafter with the start of it being a blown turbo, which was replaced. About a month later got codes requiring 4 eup's be changed and had them reprogrammed also replaced 2 injectors that appeared questionable. Think I blew out another injector shortly thereafter so I went ahead and replaced the final 4. Since this time the engine has developed a definite miss to it that is worse at lower rpm's 12-1400. Had the computer reprogrammed by mack and seemed to become more of a flutter than miss. Ran the truck 200 miles and the flutter went back to a miss. I intend to change the last 2 eup's and have the computer reprogrammed as well as changing the fuel lines, but question if this will totally correct the issue. I am seasonally employed and these issues have had a significant impact on me, however I look forward to getting this behind me and getting the truck right. My previous trucks were mechanical and I never had to be towed and this thing I've already been on the hook twice within 6 months and had the repair bill as well. Before the reprogramming of the computer tried a cut out test and no single cylinder was a for sure bet. If anyone would have any thoughts as to other directions in which to consider finding the problem I am all ears.
