Trouble Installing 18 spline A-833 through dual disc clutch assy.

A used 18 spline input would be better IF you had one.

The biggest issue I’ve had with multiple disc clutches (I hate them BTW but it’s not my car) is all the weight that is hanging on the line up tool.

Two discs is double the weight plus the other part adds weight too. To that end, the line up tool tends to sag down (highly technical term right there) and while the “socks on a rooster” fit of that plastic tool will allow it to come back out when it’s all bolted up, won’t let the much tighter tolerance input go back in.

And slinging that pig iron Hemi box isn’t fun doing it once. You start sticking that thing multiple times it starts sucking. Hard.

To that end, I try to preload the line up tool UP while I’m tightening the pressure plate bolts. You don’t need to force it up so hard you get a nose bleed. Just enough to overcome the sag.

I’ve fought this too and it’s the best way I’ve found to get the gear box in if you don’t have an OE input.
