AeroNautical Posted January 31, 2014 Share Posted January 31, 2014 I've done alot of work on my truck, the most being my transmission swap about 4 months ago. To this day, it's run so well I find it hard to believe my engines got 230,000 miles on it. Yesterday morning I started up my truck in 8 degree weather, it was cold, I doubt it's ever run that cold before. I have a cheap battery, so it lugged a bit starting, but no problems once it did, except it was vibrating a bit violently. The smart thing would be to shut off the engine, but I gave it a bit of gas before that just to see if it got worse, and it went away. I figured it was just the cold giving a rough start, then I start to drive it. During steep turns at any speed and regular braking, I hear loud metal on metal scraping, as if the mechanical fan was hitting the radiator. Then I found it was very hard to shift (ax-15 with fresh redline). That leads me to believe it's the fingers on the pressure plate. If that's the case, though, why does it stop scraping and vibrating when it's warm? It doesn't make noises while shifting or using the clutch, only when turning and braking. I had even thought it was the crankshaft, because I replaced the RMS recently, and in doing so you have to remove the rear U-strap. I know I installed it right, and tourqued it down to OEM specs, but still a valid concern. Before I start taking my transmission off and disassembling the bottom half of my engine, what are your thoughts? 4 months of smooth operation means I no doubt installed the clutch components correctly, maybe just a faulty kit? It's a RhinoPac kit. Link to comment Share on other sites More sharing options...

cruiser54 Posted January 31, 2014 Share Posted January 31, 2014 Any ticking noises with the cold start rough running? Link to comment Share on other sites More sharing options...
AeroNautical Posted February 1, 2014 Author Share Posted February 1, 2014 Check your brakes. I kept alot of information out of that article I wrote, but it's not the brakes. I've checked all four, and the noise comes from the engine/transmission (hard to localize) Any ticking noises with the cold start rough running? No, it sounded pretty smooth once it started, no sounds out of the ordinary, just the vibrations. Link to comment Share on other sites More sharing options...
Eagle Posted February 1, 2014 Share Posted February 1, 2014 How are your motor mounts? A broken motor mount would possibly allow the engine to twist enough that the fan hits the shroud. Link to comment Share on other sites More sharing options...
AeroNautical Posted February 2, 2014 Author Share Posted February 2, 2014 How are your motor mounts? A broken motor mount would possibly allow the engine to twist enough that the fan hits the shroud. The mounts are in great shape, to the point where I think the PO replaced them at some point. I'm pretty sure I narrowed it down to my ax15 and clutch components. I'm going to drop the assembly hopefully tomorrow and see how things look. If everything checks out, I'll be sure to cry about what else might be wrong in this thread.
