John;
Thanks for the "agreement", and the corrections.
You are correct, of course about the Tiger driveshaft being a strait
shot from the tranny to the rear end. I was thinking about my MGB shaft
which indeed requires indexing. Dumb.
I, too, experienced the empty dolly airborne effect. But it also often
went side to side as well. I was towing with an AWD GMC Safari van,
which may have contributed to the oscillation of the rig with it's
(relatively) soft suspension.
Our less-than-perfect road surfaces may have been a contributing
factor....
None-the-less, the dolly in the future will be my LAST choice of towing
apparatus. Bring on the flat-bed trailer!
Dave
Dave,
It's fine as long as you don't exceed approx 55-60 mph, otherwise you
get an almighty oscillation from the rig that increases in both period
and frequency if you attempt to accelerate out of it,
Maybe Dave.
I haven't had that problem, even at 75 to 80 MPH, but it might have
something
to do with the weight and wheel base of the towing vehicle. We did find
that
on the return trip pulling the dolly at 75 MPH without the car, the
dolly was
in the air about 60% of the time. I assume that saved on the tire
mileage.
Dave again
You also don't want to drive into a spot that has no drive through exit.
Backing this rig up takes more than skill, it takes heavenly
intervention!
Correct Dave!!!
You must plan ahead. It's a bitch to disconnect the dolly and try to
back the
Tiger through a McDonnell's drive through with not enough clearance.
Dave again
I think the need to remove the driveshaft began with towing cars with
automatic transmissions: many of the old versions had no "back-pump", so
the transmission had no oil circulation when it was on the over-run.
Wrong Dave Read Smit's response.
Dave again
And of course, it is possible to hook-up the driveshaft with the
u-joints out of register if you aren't paying attention. That's my
understanding of why you need to mark the flanges. Not a balance
problem.
Wrong again Dave.
What register? There are drive shafts with register but not in Sunbeams.
You
can get the register out of index when you have a spline between the
input and
output flanges of a drive shaft but the Tiger driveshaft has the input
and
output flanges welded to the drive shaft at a zero angle to each other.
