Thanks all. I've used standard length rebound springs. I know there's a discussion on Mogtalk about this, and that it's apparently better if the rebound spring can be turned when the weight is on the suspension. I'm not convinced that a shorter sopring would make a noticeable difference, so for now it's standard length.
I've made rapid progress today, and having done around six hours, the newly built stub is on the car, but I didn't get as far as the rebound spring. Interesting point about the main spring & compressors. What I found today was that if I removed the plastic spring protectors, the metal hooks have a much greater purchase. I also found that by mounting them low, the dust cover in the upper half of the spring doesn't get in the way. The new springs were just over half an inch too long to fit without the compressors, but it doesn't take much. I'm learning as I go along. The rebuilt stub simply slots into the bottom tube, then with the main spring compressed, slots into place. I really don't see why GoMog recommend leaving the top bolt until later on. Mine is already in place and only a couple of turns away from tight. I suppose that leaving the top bolt off does allow earlier location of the bottom kingpin nut, but that wasn't a problem on side 1. It's also recommended that you leave sufficient space to drop the kingpin out through the bottom, but this has not been necessary on mine.
I also found time to tart up the caliper today.
This is how it looks tonight - showing the level of compression required:
One or two other things. On the left is the new stainless lower damper stub fixing. On the right is the original. Look closely and you'll see that the bottom thread is coarser on the new part. The original part has AF threads at both ends. The new one has AF at the nyloc end, but the thread which locates into the stub axle I haven't been able to identify. Given that the nut section is Whitworth, I'm wondering if it's a Whitworth thread. And when did it change I wonder???
With the benefit of side 1, I made better use of the threaded rod on side 2.....
Wouldn't you think they would paint the stub axles????
Here's the reamer in action - I didn't take a photo of it on side 1 - too much concentration required!
Here it is painted and with the kingpin in place. I've cleaned out all the grease galleries & nipples as I've gone along.
Until tomorrow then........
