Return-Path: <RWolf99@aol.com> Gentlemen -- Attached are several pictures I took today of the IO-360-B1F engine installation (a work in progress) on my Lancair 360. Here are the salient points illustrated by the photos. Picture 1 -- Breather and Vacuum Pump A) The crankcase breather fitting points directly at the engine mount. It was difficult to route the hose to the desired location of my oil-air separator without interfering with the engine mount. I purchased an industrial brass fitting from Parker (makers of Aeroquip hoses -- or is it Stratoflex?). This fitting is a 45 degree hose barb with the appropriate sized NPT thread. We "simply" screwed out the old fitting and replaced it with the 45 degree fitting. "Simple" is in quotes because the angled fitting could not be installed without undoing the top engine mount bolts and allowing the engine to sag just enough to provide clearance to spin the fitting in. Of course, we supported the engine with an engine hoist during this operation. If anyone is interested, I will be dropping by the local Parker Store on Monday and will find out the part number. B) I need help here -- I am not using the mechanical tach drive. I need to cap it off somehow. The vacuum pump (Tempest) is ridiculously close. I have measurements for machining a special cap but clearly everyone with an electronic tach (i.e. almost all of us) have capped this off. How did you do it? Picture 2 -- VA182 Bracket A) This is a photo of a bracket that Vans sells for their IO-360 installations. (This photo was supplied by Vans, so no lawsuits for copyright violation, please.) This can be used on the Lancair with an IO-360-B1F with the 90 degree elbow from Airflow Performance. You need to cut off the bent tabs and bolt on cable clamps from Aircraft Spruce. Apparently Vans uses cables that are secured with bulkhead nuts. I somehow managed to obtain from Aircraft Spruce the kind that slip into a slot. More on this later. Picture 3 -- Throttle Clamp A) In this picture the modified Vans bracket is sandwiched between the 90 degree elbow and the phenolic spacer. A cable clamp is bolted onto the bracket and holds the end of the throttle cable. Picture 4 -- Mixture Clamp A) In this photo, a hardwood block is C-clamped to the Vans bracket. A cable clamp is kinda masking-taped to the block. This block represents a required 1.5 x 1.5 inch rectangular tube. The tube is 3 inches long. This spaces the cable clamp sufficiently downwards and outboard so that there is a straight run from the clamp to the mixture lever arm. I'm still searching for a 1.5 x 1.5 hollow aluminum tube but have an internet quote for a 4 foot piece. B) There is a low-profile 90 degree fitting on the bottom of the fuel servo, to which a fuel line is attached. This is a "test fitting" from Parker and looks identical to the Lycoming fuel pump fittings, except that the threads are different sizes from the Lycoming fittings. They are smaller than a standard AN elbow and are required in my installation. Picture 5 -- Bracket Overview A) This is an overview of all described above. Picture 6 -- Alternate Air A) This is an alternate air assembly from Airflow Performance. It bolts onto the fuel servo and can accept air from straight ahead (unfiltered ram air) or from the angled inlet. I will be either sticking on a piece of 3.5 inch SCAT tube, or fashioning a 90 degree elbow from fiberglass and attaching the SCAT tube to that, and running it under the starter and up in front of the #2 cylinder for filtered air. I expect some minor surgery on the aluminum angled inlet to allow the air path to make the relatively tight turn under the starter. I will also be swapping the control arm from the starboard side to the port side to make the cable run to the cockpit more acceptable. This looks pretty easy to do. Hope this helps... - Rob Wolf LNC2 81% Parker CO
