A simple home made wheel pusher to adjust tight B2B's simply and easily.

A guest post from Terry Smith, with details of a useful device to move wheels on axles. 

I've made a wheel pusher from a plumbing fitting. 

Basically, I've have removed the olives from a compression ring union fitting (8mm pipe), done up the nuts tight and then cut a 3mm slot straight through one side with a small angle grinder. This allows me to use the fitting without having to take the wheel sets out of the truck.

I then undo one nut so that it gently holds the fitting between the wheels, allowing me to centralise the nuts on the wheels. I can then use spanners to hold one part while gently turning the nuts and pushing the wheels apart. 

Simply by chance, one full turn of the nut gives a back-to-back setting of 1.132" which is a figure I settled on a few years back as an aim for re-working wheel sets that needed it, for my operating circumstances. 

This fitting works much better with more and finer control than my previous method of removing the wheel sets from the trucks and using a NWSL HO sized wheel puller/pusher. It is much quicker as well.
