I quieted my Oliver steps

[Townesw]

The steps on our Oliver have always been loud when being lowered or raised. I have taken some “steps” that have made them quieter. And before you ask, no, I don’t have before and after noise level analytical data. I just know that they are quieter. 
 

1. I draw filed the top and bottom of both slots. 
 

This picture after a couple of draw passes with a file shows the roughness left by the machining process. The bright spots are the high spots of the rough surface. I suspect that one side of the slot was smoother than the other due to the direction of rotation of the cutting tool.

 

Picture of the bottom of the right side slot after several passes using a draw file technique. Be sure to keep the swarf cleaned out of the file. There is a light shining on the surface. It is much smoother. 

I then applied some silicone lubricant to both sides of each slot and allowed it to dry. 
 

2. I next reassembled the steps and placed (6) rubber bushings on the stainless steel rod to dampen the vibrations that the rod made when being drawn through the slot in the aluminum sides.
 

3. I also replaced the aluminum spacers on each side with polypropylene spacers. 
 

 

 

4. I removed the female half of the sex bolts that act as the pivot for the lower step. I used a T50 torx bit but I think it is actually the next size larger. I applied silicone lubricant to the inside of the hole in the step side and to the outside of the binding barrel and allowed it to dry before reassembling.  I will probably drill those holes out to receive Oilite bushings this winter but this will suffice for now. 
 

 

 

 

Material used.  The rubber bushings are actually 1/2” ID x 2” OD x 2” long. The holes aren’t perfectly centered but I didn’t need for them to be. I chose 2” OD so that they would clear other parts of the step assembly. You will have to lubricate the step rod and the hole in the bushings to be able to assemble them. The polypropylene spacers came from McMaster Carr. Be sure to use a dry silicone lubricant instead of grease. The grease will retain grit picked up off the road.
