Engine Mount & Landing Gear

Step 1:Using a 3/8" bit final drill one of the two 3/16" holes in the top of the Firewall Assembly common to the WD-1001-D1 Dyna 1 Engine Mount. Be sure to drill perpendicular to the vertical face of the Firewall Assembly.

Temporarily bolt the engine mount to the Firewall Assembly using this hole and the hardware called out in Figure 1.

Align the engine mount with the second 3/16" hole in the top of the Firewall Assembly and final-drill this hole using the same bit. Keep the engine mount in place while drilling to help maintain the alignment of the bit. Secure the engine mount to the Firewall Assembly, Then final-drill the remaining four holes. Place a bolt in the holes after each is drilled.

Step 2: Remove the WD-1001-D1 Engine Mount from the Firewall Assembly, then permanently bolt the engine mount in place using the hardware called-out in Figure 1.

Step 1: Pull the bearings from the Main Wheel Assembly by removing the snap-rings that are retaining them. Pay close attention to how the bearings, grease seal rings and grease felts are installed so that they can be reinstalled in the same way. See Figure 2.

Step 2: Split the Main Wheel Assembly by removing the bolts holding the Brake Disk and the Inner and Outer Wheel Halves together.

Step 3: Dust the U 15X6,0-61T Tube and the inside of the U15X6.0-6 Tire with talcum powder, then mount the tube and tire on the Inner and Outer Wheel Halves. The red dot on the tire is installed next to the valve stem of the tube. Bolt the wheel halves and brake disk together. Carefully observe the manufacturer's bolt torque specifications shown on the document in the wheel/brake package.

Step 4: SLOWLY inflate the tire to 25psi. Deflate it fully and re-inflate it SLOWLY a couple more times to work out any wrinkles in the tube. It's a good idea to do this with the valve core removed; in the event a finger gets pinched the tire can be quickly deflated. The final inflation pressure in 42 psi.

Step 5: Be sure the bearings are fully greased with Aeroshell #5 or equivalent. Reinstall the bearings, grease seal rings, and grease seal felts in the same order that they were removed. Make absolutely sure the the smaller grease seal rings is installed on the outboard side of the Main Wheel and Tire Assembly, and the two larger grease seal rings are installed on the inboard side as shown in Figure 2.

Step 6: Split the nose wheel assembly by removing the bolts holding the two Wheel Halves together.

Step 7: Remove the nut and washer from the valve stem of the U 5.00X5-61T Tube. Dust the inside of the U 5.00X5-6 Tire with talcum powder, then mount the tube and tire on the Wheel halves. The mark indicated in Figure 3 on one of the wheel halves should be aligned with the notch for the valve stem in the opposite wheel half. As before the red sot on the tire is installed next to the valve stem. Bolt the wheel halves together.

Step 8 Slowly inflate the tire to 25 psi final inflation is 40 psi

The instructions for the installation of the main gear are given for the left side of the fuselage. The right side is a mirror image.

Step 1:Slide the U1001 Main Gear Leg into the WD-1021-L Left Landing Gear Mount as shown in Figure 1.

Step 2: A hole is drilled through the upper end of the landing gear mount socket. The hole in the top size is drilled to final size while the corresponding holes in the bottom is drilled undersize. Align the hole in the main gear leg with the top side of the socket.
