Installed starter cable and engine ground wire to starter housing. Installed AN 816-4D fittings in #3 cylinder for MP line and on accessory case above Rt mag closeout plate for oil pressure line. Measured for OP, MP and FP lines to order from TS Flightlines. Installed LSE Mini sensors on mount behind starter ring gear. Installed ring gear and set sensor gap @ .040 (range is .030 to .060). Made gapping tool out of strip of .040 alum and pushed sensor forward in mount so it was snug against gapping tool and sensor ring on rear of ring gear. Snugged mount screws while ring gear still mounted. Removed ring gear and tightened mounting screws with blue Loctite.
