  1. There are rebuild kits for these things? I found one on ebay for $600 which is $1000 less than Mack quoted me, i just refuse to believe there isnt a rebuild kit for these things.
  2. 2001 CH613 E7 300 - Truck began blowing off once every 30 seconds or so, so I did an air system service...new dryer, new spitter valve, cleaned housing and mount, new govenor, checked govenor lines (not mounted to compressor). Symptoms continued, replaced check valve in primary tank, symptons continued. At this point began to sniff around on the interwebs to see what I am missing, and came across the "unloader" option and tested to see if this could be the problem - removed 1/4" line that runs from compressor to dryer at 120psi and there WAS air coming out of the line - so I called Mack to get an unloader kit. They told me there is no unloader kit and i need a new compressor. I find this SO hard to belive. Its a Wabco 8235-S9111530557. Am I missing something? Are there kits out there that I am not being told about...anyone have any similar experiences? Thanks.
  3. Id really appreciate it. Were between a rock and a hard place here. The reason that I think someone else had played with this thing is that it looks like someone has worked on it before, and the build report I got for this truck said that it was installed with the heavier springs and the rotators on the bottom. I dont know if build reports are totally accurate or not however. If no one has worked on this before, besides putting new solenoids in the jake, what would cause the unbalancing? Is it driver error or just a normal wear feature?

  5. To put a jake on our E7 - 2002 - it was like $6000 for the parts and the install...Jacobs, not a dynatard or a power leash. My trucks with Jakes are great, the dynatards are worthless
  6. Hello All- Have a 2001 Ch613 with an E7 330...bought used from Ryder (if ever given the chance...dont) Has 223k original miles on it...I have put 10k on it. Last week I fired it and heard the dreaded valve / broken spring noise. Couldnt get a Mack tech to my shop to look at it, so I pulled the valve covers myself and with the help of a local mechanic began diagnosing the issue. To cut this story down to under 20 pages...we finally realized that at some point someone had gone into the valves, replaced the springs but didnt put the bottom rotators back in, instead put them on top of the spring. The rotocoil (the part the washer spins in) had broke on almost every valve which meant to us that we needed to reinstall all of it, springs, rotators, washers, keepers, and seals. It took me a week, but I got the correct parts and began pulling 2 and 5, and when we went to re-install the E7 rebuild book says you MUST have the "Mack" tool to install the seals. To be more brief...its going to take at least 2 weeks to get the tool and as Im sure most of you know (and now I do)...no body works on Mack heads anymore...they just install remans. So no one within a 500 miles radius of me has the damn tool. Does anyone have the tool and want to get rid of it, or know a way around this or should I just punt and give back the parts and buy reman heads? Help.
