- Install your steering knuckle assembly in the vise with its brass jaws. You can mount the knuckle components in the vise either horizontally or vertically while performing the reaming procedure.
- Insert the king pin reamer into your steering knuckle until its blades touch your king pin bushing.
- Rotate the king pin reamer, applying light downward pressure in a smooth pattern. Make sure you do not apply too much pressure.
- Slide your king pin reamer out of the steering knuckle assembly's bottom part. Rotate your reamer opposite its cutting rotation direction if you need to remove it from the top.
- Clean and remove your king pin bushing material from your steering knuckle assembly, while making sure to remove the material from the assembly's grease channels and dimples.
- Use a wire wheel to clean the 5/8-inch bolts of the brake backing plate, and run a tap right through the lower steering knuckle assembly threads. Flush it out with your brake cleaner, and dry it with compressed air.
How to Use a King Pin Reamer
Whether you will use it on a machine or use it by hand, your king pin reamer's function is to produce the most accurate and smoothest surface in bore, including that of a bush or a bearing. This will allow the bolt, pin or shaft to easily enter and achieve a good fit. This is why a king pin reamer is a lot better tool than a drill for this purpose. Many people have switched to this tool to produce a superior finish and for doing normal machining on one's lathes.
