This was honestly the last thing I expected to happen. I started up the engine for the 1st time and I heard a chirping that I thought could be the pilot bearing. Sound went away for a while(started engine no more than 20 times running only for 2 min)... Today I ran it for 30 minutes and the sound came back but in a tic tic tic type sound. TO GET TO THE POINT... I got a camera into the bell housing and saw a bunch of metal shavings, small/large strands. Eventually I located a patch on the bell housing wall that had been chunked up by a rotating assembly. Flywheel shows no signs of wear. Could not locate what was hitting the bell (battery ran out on scope). Pressure plate seems like the only possibility... Any advice??? I know I need to pull the tranny... Hell, if the bell is possibly out of spec enough to have the problem I'm having, what else am I going to run into... Its not my first clutch job either...Maybe my last ha ha. Thanks!!

Sounds like it's not interfering THAT much.. I would call the Quicktime people and get measurements, to ensure that it was manufactured correctly (it is a fabricated part after all.) Everything is doweled, or i'd suggest that you loosen the hardware and try to move the bellhousing/transmission to where it had more clearance. Remember also that the clutch will expand with heat, so you'll want to make sure it's got plenty when it's cold.

Interesting, Quicktime said should use a 11inch disc. even though ppl use 12inch monster with no issues. Interested in your findings.

Thanks for the responses. I guess I missed the part about the Quicktime bell requiring an 11'' disc... Well, I will post some pics of the carnage tomorrow when I pull the tranny... I have a hunch that it wouldn't be grinding if the bell housing was as centered to the crankshaft as can be. Before I was told by Quicktime to just just mount it up and forget about it, I did my best to find the total indicated run-out from the bell housing center in relation to the crank center. If I were to compare it to a clock, the bell seemed to be up and to the right (2 o'clock) from center. So I have some off-set dowel pins coming soon to either fix the problem or test my theory... I feel if I left the transmission/bell/crank alignment as it is now, I would probably chew up pilot bearings, and that would go over like a turd in a punch bowl.......

I have a QTP housing and the Mcleod RXT, now I'm worried about this. Please update with findings.

I have seen several post of people useing a 12 inch disc and had no issues. The RXT I dont know about. But I just installed my quicktime bell and a monster 11 inch and went together and lined up fine. just waiting on a new master.

I've sold a ton of the RM8020 bellhousings and not a single complaint reported back to me.

It was good talking to you on the phone, let me know what you find out.

So I located the problem or at least half of it... The grinding noise was the input shaft rubbing on the slave cylinder collar (the section that slides over the input shaft), really strange. Input shaft was only scored on half of the circumference and was hitting the upper center of the slave collar. I really have a lot of trouble getting the trans to go in the last 1/4'', about the time input shaft would enter the pilot bearing, and the trans dowels meet the bell housing. I'm thinking something is forcing the input shaft up into the slave collar. Clutch disc, bell housing alignment are top candidates...I'm at a loss at the moment and running out of ideas. I aligned the bell to within .005'' mis-alignment, still cant stab it in that last 1/4''... Through this process I have not hooked up the hydraulics and am thinking that that may help settle the clutch disc to where the input shaft wants it to be by dis-engaging it ("IF" it is not aligned properly, don't really trust these plastic alignment tools). Even then, that wouldn't solve the issue of not being able to get tranny in all the way...This is a brand new T56 magnum and I can't imagine that the input shaft is bent??? Anybody have any wisdom, this is driving me up the wall... Thanks!!!

If the input shaft is rubbing the slave, you definately have an alignment issue. Check to make sure nothing got pinched between the block and the bellhousing when bolting it up.

I second what was stated above. Something is misaligned when putting it together, more than likely it's something simple that is staring you in the face.

Well, at least that is typically the way it works with my luck.

If you have any other clutch questions just give us a call.
