2010 Niagara electric lift. I went to open the trailer today, and at start up, there was a fairly loud bang. It has happened the last couple of times I've opened it. Lift works functions up and down. I took off the wiffletree cover plate to grease it, and found a broken part. There is some kind of metal bushing riding on the wiffletree screw, as well as a plastic/nylon bushing. The plastic/nylon bushing appeared to be wrapped around the metal bushing. I took the broken plastic bushing out, it appears to be the same size as the metal bushing. Is this just a spacer? It doesn't seen to have any effect on the raising or lowering of the top. I looked at the parts book for a 2010 Niagara, and there is a bushing listed (#6-21/4" bushing), but these two parts together aren't 2.25 inches. If you add both (metal and plastic) loose bushings to the bushing that is attached to the screw, it might be 2.25 inches. I am hoping that this is just a spacer- Can anybody identify? Or define a purpose? @GreyFox Edit- What appears to be the brass bushing is actually two "washers" (last pic). So there are actually 3 parts between the bushing and the cable attachment block - two brass washers and the (now broken) plastic "washer".
