That's great........now how about not having them made by the lowest bidder so they can come apart and ruin 2 perfectly good turbo's.

jr-transport Thanks this.

well the 1st issue i see is that they made the sleeve out of stainless steel, um i think that they should have used something like cast steel, as SS gets fatigued quickly when cooled and heated over and over causing fatiuge cracks.

What year did they start putting on those exhaust sleeves in CAT's ?
-
This literature was from October 1993.
More often than not they break at the weld joint and are on the 4th or 5th Generation of this sleeve, the ACERT were the 2nd I belive and there have been 2 since and the weld joints are better now. -
I think it actually started in the late 80's with the 5KJ 3406C engines with the round port heads and the B-Model square port manifold. The sleeve part number is 194-8124 and is listed as 17 in the picture
