You need to replace the hinge pins with stainless steel 3/16-in. welding rod. Some have used a reamer attached to a pin to first ream the hinge. I have found that step to be unnecessary. I have been able to install the 3/16 rod into new hinge without reaming. It is a tight fit, but once installed, there is no play in the hinge. The pins must also be replaced on the inner gear doors to prevent too much vibration there, and the entire hinge must be replaced once in a while. Last year, I had to replace these hinges and pins after about 900 hours on the hobbs. The doors were beginning to vibrate too much in the prop wash.
