    I came up with 55 lbs, except in Eaton Clutch instructions 55-60? I think. I torqued them at 58, with blue locktite, new lock washers only, no flats.Dont want to risk stripping aluminum bell. Ive read of higher torques for steel bell housings,

    Some of you may saw, had to start another thread. Peterbilt ordered me wrong trans. RTLOF
    SHould be just a regular RTLO. Shifter is about 3 inches too far forward. I didnt catch it until i buttoned everything up and was putting shifter on and it hits the dash in neutral. Hopefully i can change out the shift bar housing while in the truck but still, this is gonna cost me a few thousand dollars in down time and my labor. Anyway, ill let you know what pete says in morning when i call.

    Ok so im sure you want to know how the install went even though i might be removing it again lol. I almost threw a temper tantrum after this nonsense but i need to laugh, its been a bad week over all.
    So after some long and hard thought about putting clutch on the trans and mounting that way, i opted out. Why? i really have no one that could help me do it that way. I would need someone to turn my barring socket while i do the bolts. I couldnt see doing by myself. That barring tool is so dam slow and i would have to stop and look a million times.
    I welded an input shaft to a peice of steel tubing and the welded the tubing to the harbor freight jack plate. Threw my clutch on to that setup. Got on my creeper seat and lifted the unit up into the pilot bearing and bolted everything in place and the wood shipping blocks fell out. While the input shaft was still in there.
    Obviously, next i used a grinder to cut the tack welds off my new clutch lifting tool to remover off my harbor freight trans jack. I have alot of tools and tend to be able to get things done so next, using my front end loader, i lifted my trans up with engine lifting setup and chained to the lifting eyes on my trans. At this point with the 2 chains the trans and bell housing was equal weight on each side and balancing. I took a measurement off the concrete to the bottom of the motor bellhousing which was 20 inches. I then raised the trans with my loader to match the same height with the trans bellhousing.
    at this point, i cut 2 pieces of wood for front and back of trans used 2x2 about 2 foot long. Bolted them to hf jack using existing bolt holes. Counter sunk them and ground off any metal still protruding.
    While trans was in air with loader, i was able to jack the trans up finding the EXACT dead center of the weight being balanced on the top plate of jack. So i kept jacking till slack was evident on the chains going to the loaded. Then i threw a ratched strap around the plate and trans and unhooked from loader and lowered the jack.
    Doing what it got rid of the dangerous possibilities @Rideandrepair made everyclear about with cheap harbor frieght jack. there was no strain on the week points and while the trans was close to mating with pilot bearing, the knobs worked with COMPLETE easy tilting front and back and left and right for alignment.
    Took me 3 adjustments to get the splines into the clutch, after that, i went to the rear and used my foot and leg pressed the setup into the trans and pilot bearing. Took 2 attempts with that one. Only time i cursed is becuase i banged my head a few times on various parts underneath truck. Blood and bumps. But YEah had no wrestling around and the #### thing went in within 10 minutes.
    Not to take away from anyone that uses other methods, i came up with a different solution becuase i swapped trans, when you guys are swapping clutches, you dont remove the trans from the jack. I had the trans on loader and was able to find dead center weight distrobution which made install a breeze with making adjustments with tilting. An engine lift could help with that if you dont have a loader
    Sorry for the long post. Some people like them i assume. Also, trying to stay positive. I might have to yank this thing again. If i do, ill take pictures

    This is how both of my clutch discs looked. I’m narrarating in the video like I’m sure it was in bad shape from previous owner. I have replaced clutches before in cars in pick ups and never saw cracks or movement like this. What’s going on with this clutch to your knowledge. @Goodysnap or whoever else can shed some light

     
    Rideandrepair Thanks this.

    There ya go....... your transmission was probably fine all along. It was just your clutch that had the bag marbles sounds.

    Your probably right. But I’m anal about my truck and the trans has a lot of miles on it and 3/7 gears wasn’t so forgiving. Instead of tearing into it and the cost, I haven’t lost sleep on it. I like cleaning things up with new components.
    So is that a pretty banged up clutch from the previous driver doing wheelstands? What’s going on from what you can see in the video?

    I wish I’d taken pictures of my discs. Half the springs were missing on one, pads wore completely out on another. In the past, I’ve had the same problem with springs falling out. The discs get rusty, springs wear out, before pads.I don’t know about that movement, but the rest is just normal wear and tear. I’m very easy on a clutch, But the springs get weak,the discs fall apart, causing springs to fall out, before the pads wear out.Both Times I still had gotten over a million miles on the clutches, though.

    90% of clutch abuse or damage is from people starting out in to high gear loaded. So hard on stuff.
