this is a reman turbo with 8k on it and out of warranty so this is on me. on the way to work it spooled up and made a terrible sound then on the way home it started smokiong pretty bad and even worse on decel. total distance traveled with this condition was maybe 50 miles, unreal the bad luck ive had with this new reman motor from catapillar. this just in a long string of probs since i put it in back in aug 2011.. thanks
I suggest you rebuild it. I would look really hard at the bearings and oil passageways as you disassemble it. If you find plugs of silicone, you have bigger issues. A new or a rebuild will cost you considerably more than rebuilding your own.
I too suggest rebuilding it. It really isn't hard. You will want this kit. There are cheaper ones on ebay if I had to do it all over I would order the kit from riff raff and get all the bolts. That is provided the end play and shaft clearances are within spec. http://www.riffraffdiesel.com/mm5/m...t_Code=740659-0008&Category_Code=F731-TRB-TRK
ok, i,ll get it out this saturday and order the kit tonight......
what exactly fails on these turbo's and how do they fail/break...just wondering because as i said b4, this unit has less than 8k on it when it went away
i havent looked yet but im sure theres a thread here that can walk me through the rebuild
I would order the replacement bolt kit with your rebuild kit. I had to use allen bolts to replace two of the 12pts that got stripped. Also, make sure you have an 8mm 12pt socket and plenty of penetrating oil to soak your bolts/turbo before you even start removal. I wasted a day trying to find the proper socket(used a standard but it didn't grip as well as the 8mm) and replacement bolts that'd work.
When I rebuilt mine... I found the drive wheel had been chewed up badly. I did buy that exact same kit, and it certainly got better.... But I eventually bought the center cartredge from Riffraff. That was significantly cheaper than buying a new one and it worked great.
