Fitting is near identical to using the original phosphor bronze bearing, except you use the needle roller bearing. i.e. You replace the phosphor bronze bearing with the needle roller bearing.
You have to shim the trunnion irrespective of which bearing you choose to use.
If you rebuild your kin pins and don't use a needle roller bearing you still need to shim for correct vertical end float.
And shims are available from most of the usual suspects.
Lots of other people have fitted them over the past 10 years, and I'm not sure why you'd need a machine shop to get involved?

However, simply as a warning to anyone reading this discussion who is not completely familiar with all the issues, I have read that they (trunion roller bearings) may require shimming to obtain the proper clearance (vertical end float) of the kingpin & it is my understanding that this is especially difficult because no shims are available or machining may be required.
