It took my nephew and I almost 4 hrs to install the left main gear leg. It was a very difficult task but after some coaxing we finally bolted it in place securely. I was dreading the next day because I was going it alone with the right gear since my nephew had to return to the east coast. To my surprise, it went very well and only took an hour or so for the right leg. Unfortunately a serious issue arose with the toe in / toe out procedure. The right side was barely within limits but easily fixable with the expensive shims from Vans. The left side was way out of limits and would require more than the maximum suggested limits for shims. After sending photos and measurements to the mother ship, they admitted they had a batch of early gear legs that weren't cooled properly in the manufacturing process and ended up warping. Evidently I had been shipped one of them, so they sent me a brand new one at no charge. That one now went in with no problem also but still required a shim. I completed SB-00027 after the nose gear and engine were on, however I did not run into any issues with the process.The nose wheel fairing was a real bear. It was impossible to complete per Vans instructions and measurements. After discussing it with Vans, I will leave it as is and decide during the annual condition inspection if I need to re-do it. I added Flyboys Accessories "Tug Guard" to the nose wheel fairing to help prevent chipping the paint.
