Engine Plumbing - 10 hour (235 Total)

Over the course of several days I routed a majority of the engine plumbing. This was a tedious process of positioning and re-positioning trying to get everything to fit well together. The work consisted of routing some oil lines, fuel lines, fuel pressure sensor, fuel distribution box, and throttle cables.

The pictures below do a better job of describing the routing.

Sparkplug Wires- 1 hour (225 Total)

I found some new plastic wire brackets to use on the sparkplug wires. I used these to individually hold the sparkplug wires at the fuel pump. I did not like having the wires compressed together in a single bracket.

Parachute Bracket- 6 hours (224 Total)

Figuring out how to mounting the parachute in the nose was a difficult task. Because the S-14 Long Wing is so tail heavy to begin with, adding the 15 extra pounds of HKS engine caused the center of gravity to be very far back. With my estimated CG calculations, I would be right at the edge of the CG window if I placed the parachute in the rear of the fuselage. Moving the parachute to the nose of the plane moves my CG forward by almost 2.5 inches.

My other goal with the parachute mount was to create a location that the battery would be able to sit.

I used the BRS supplied plate as a starting point. I jerry-rigged the plate to correct location while I dry fitted the nose cone into place.

Once I had the right location for the plate, I drilled two holes into the plate to accommodate two 90 degree brackets that would connect to two pieces of 3/4" x 3/4" aluminum angle. These two pieces of angle aluminum are the top pieces you see in the pictures. They are spaced such that my battery will sit inside of the frame they create.

The two lower pieces of aluminum angle keep the plate from rotating around the brackets. These pieces are connected to the plate with two metal pipe/wire brackets that have be deformed to grip the at an odd angle. The other ends of the aluminum angel is connected to the planes frame with similar, but not deformed, metal pipe/wire brackets.

Fuel Filter Brackets - 3 hours (218 Total)

I spent a lot of time researching the correct fuel filter to use. I came up with the 33001 filter from Wix. These filters are sold by Carquest under the 86001 part number. They are rated at 12 microns.

The HKS manual states to use a 15 micron or less, mesh type filter. Unfortunately, most filters and their suppliers don't state the filter's micron rating.

I spent several hours creating mounting brackets that would hold the fuel filters. I use some 3/4" x 1/2" aluminum angle which I drilled a 5/8 inch hole in. The hole accommodates a rubber grommet that holds the filter nicely.

Oil Pressure Sender - 1 hour (215 Total)

Today I bolted on an oil pressure sender to the engine. I purchased the sender from Aircraft Spruce. It is a 0-150 PSI unit from Mitchell

Panel Wiring - 6 hour (214 Total)

I spent several hours wiring the component of my electrical panel together. I am several hours from being finished but this is the majority of the power and ground wiring.

Sparkplug Wires - 1 hour (208 Total)

Today I routed the sparkplug wires. This required five different wire clamps to keep the wires from rubbing on any of the metal components.

I needed to replace the lower carb bolts with a longer ones to accommodate the wire clamps.

Electrical Panel - 4 hour (207 Total)

Over the course of several days, I laid out my electrical panel.

I started out by cutting out a piece of cardboard that fit the dimensions between the middle and rear cabanes. After laying out all of my electrical components on the cardboard and determining the best layout, I bolted the components to the cardboard.

I originally thought that I would use two panels, one on the left and one on the right, but it turned out I could use one large panel if I used both sides.

I then installed my cardboard electrical panel into the plane. Once in the plane, I did some adjusting of the components to facilitate wiring.

I intend to completely wire the engine and panel to insure proper fit before replace the cardboard with a piece of sheet metal.

CHT and Oil Temp Probes - 1 hour (203 Total)

Today I installed my CHT and oil temp probes. These probes came with my Stratomaster instrument package from MGL Avionics.

To allow the CHT probe to be fully installed into the hole provided in the cylinder head, I needed to shorten the probe's spring. Surprisingly, the spring was easily cut with a pair of wire cutters.

Prior to installing the probe, I added a generous glob of thermal grease to the tip of the probe.

I used a pair of vise-grips and a socket to tighten the probe. I tightened to a snug fit.

The oil temp probe threaded directly into the opening provided in bottom of the oil tank. I used Teflon tape to seal the threads.

Oil Tank - 1 hour (202 Total)

After many hours of holding the oil tank in different positions around the plane trying to find the optimum location, I finally decided to mount it on the middle cabane on the left side.

This location will give me easy access to the take from the door allowing easy filling. It will also allow easy draining since there is plenty of clearance between the drain plug and any obstacles. Since it is mounted between the left cabanes and left wall, it is making use of space that would normally be wasted. The tank needed to be oriented just right so it doesn't come in contact with the planes skin or the aileron cable.

A few negatives of this location are: The sight tube will be difficult to see but I may be able to see it from outside the plane through the left window. This location is also close to my head. If there is considerable noise from the sloshing of the oil, I may have trouble with keeping my bladder comfortable!

I mounted the oil tank using 1" cushioned wire clamps. Placing two clamps on the middle cabane but in opposite facing directions allowed me to compensate for the left-right angle the cabane sits at. I used a piece of aluminum angle mounted from the tank bracket to the rear cabane to keep the tank from rotating around the middle cabane.

I needed to attach the tank's mounting bracket in a funny fashion to get the fittings to face the rear of the plane.
