First time I've seen this. In CF there's am
assembly with two cylinders and two risers. One fits up nicely, the other is a
different story. If anyone would like to give it a try, see if you
can insert the Riser into the Clevis. The Riser is unconstrained and will
drag anywhere but won't insert into the clevis; least I can't get it to; gives
a constraint error.

Hi Larry,
I think it's a geometry thing
- the position of the clevis on the cylinder is too far retracted to allow the
riser to insert to the Frame Tube AND to allow the roller to maintain tangency
to the left(top?) tube. If you suppress the insert constraint
between the clevis and the cylinder, then the constraint you are attempting
works. I can post in CF if my explanation is lacking 🙂
I tried doing just a standard
Mate on the centerline of the clevis thread hole and the cylinder rod, but
that resulted in a constraint error as well, so my thought is that perhaps the
cylinder centerline is just slightly off from the centerline of the
riser/roller combination. Hopefully this is enough to get you
going.
Cheers, Alan

Larry,
The cylinder rod cannot be
pulled out!! The fixed length will not let the clevis meet the lug on
the arm assy. I fixed the arm to the lug on the arm to the tube. I tried
to get the cyl. to meet the lug at the other end of the arm. It
fails. The rod has to extract out of the cyl. but it is
fixed.
