Further to the
build-post, here is the home made aluminium LDV126/127 pilot shaft puller tool assembly sequence!!
The entire purpose of the tool is to insert the pilot shaft into the main bearing without any applied forces to other parts, and only contacts those two parts.
The final picture shows how it would be implemented during final re-assembly of the gearbox.
A short piece of solid aluminium tube was created for the "workhorse" end of the tool where the most forces will be applied. I am worried about tool failure here.
The remainder of the split component is retained by an off-the-shelf piece of profile tube with an ID/OD of 30/40mm.
M16 thread is wound into the central split part as far as it will go. I am tempted to make another solid collar for this end...but I think the next part (image below) in the tool-set will do most of the work.
80x80mm profile with a 40mm ID. This is the part that comes into contact with the main bearing and will do the "pushing" as the central components do the "pulling".
The external sheath is longer than the internal components so they can slide upwards as parts are drawn together.
A short piece of scrap flat-bar is used as a monster washer across the top of the tool. Keep cranking down on that nut, and the central components are drawn upwards.
The M16 thread itself does not rotate. It is bottomed out into the split components.
This is where all the action will happen when I'm feelin' the success mojo pumpin'. (It was 40 degrees C today...working outside was no fun. Final reassembly will happen later...)
