[ VIDEO TRANSCRIPT ]

Hi, I’m Mark from eReplacementParts.com. In this video, I’m going to show you how to install a new bushing housing assembly on a Ryobi trimmer. The bushing housing assembly is a critical part of your string trimmer. It mounts to the trimmer’s shaft and accepts the cable.

It also has the mounting locations for the guard. It contains the bushing so that the shaft can rotate, and the shaft itself where the trimmer head mounts. Common problems with the bushing housing assembly are broken mounting tabs, stripped out screw holes for the guard assembly, worn out bushings, a bent spindle, or stripped threads where the bump head knob mounts.

Replacing the bushing housing assembly is easy to do, and I’m going to show you how. Bushing housing assemblies, as well as many other parts, can be found on our website. Let’s get started.

I’ll begin by removing the bump head knob and the spool. I’ll use a small pick to pull the C-clip away from the shaft. Now I’ll remove the plunger and the plunger spring. Now I’ll remove the E-clip, the slider and the two slider springs. I’ll use a pair of split-ring pliers to do that. Now remove the retaining clip that secures the trimmer head to the shaft. This part is not reusable, so you don’t have to be real careful when you are removing it. I just pry it away with a pick and then use pliers, or even a cutter, to pull it away from the shaft if necessary. This one’s going to come out pretty easily.

Now I can remove the outer spool from the shaft. The plastic outer spool is pressed onto a metal nut on the back side. To remove it, I’ll strike the end of the shaft with a rubber mallet. You don’t want to use a steel hammer here, because you will bend and damage the shaft. Now I’ll remove the bushing housing assembly.

First, I’ll remove the guard, then the retaining clamp, and the anti-rotation screw. Next, I’ll loosen the bolt that secures the clamp to the shaft. Now remove the anti-rotation screw and separate the bushing housing assembly from the shaft. Now we can install the bushing housing assembly. Before I do though, I want to make sure that I remember to slide the retaining clamp over the shaft, then the shaft into the bushing housing assembly. Make sure everything lines up, and I’ll secure these two together with the anti-rotation screw and the clamp.

Now we can install the outer spool. I’ll slide it over the shaft, making sure to line up this recessed portion in the back with the nut on the shaft. Once I have those aligned, I’ll tap the spool onto the nut.

Now I’ll install a new outer spool retainer. I slide the retainer over the shaft. To install it, I’m going to use a special tool that I have. This tool has an inner diameter that gets slightly bigger than the diameter of the shaft. You probably won’t be able to find a tool like this, but a piece of metal tubing has that same inner diameter will work great. I slide the tubing over the shaft and then tap the retainer into place…
