Welcome to watch the teaching video series on the installation and testing of NGH GF60i2 engine. In this episode, we will introduce the installation of the engine on the test bench, as well as the electrical and oil circuit connections.
This series of videos is suitable for NGH GF60i2 Engine, support custom service, welcome to contact us.
Firstly, place the NGH GF60i2 engine on a flat surface and prepare the necessary accessories and tools for installation.
Pour alcohol onto a dust-free cloth.
Clean the position of the steering gear installation mount.
Wipe it clean and dry it, paste one side of 3M Double-sided tape on the installation position of steering gear, and press it firmly.
Note: Keep the other side of the 3M adhesive backing paper and remove it when installing the steering gear.
Insert the matching bolts with gaskets into the engine mounting base.
Place the engine mounting base horizontally on the desktop and place the mounting pillar on the bolt.
Place the engine vertically into the mounting hole on the engine base.
Note: Before aligning the holes, first confirm that the installation position of the engine carburetor and steering gear is on the same side.
Install matching nuts.
Compare and use matching wrenches for tightening connections.
Install four shock absorption columns on the installation end plate at the front end of the test bench, and assemble them using matching nuts.
Note: To prevent excessive force from damaging the torque sensor inside the test bench, we advise not to use the wrench to tighten the nut.
Install the exhaust muffler bracket on the end plate of the test bench and tighten it with matching bolts.
Adjust the engine position so that the studs at the test bench end pass through the engine mounting holes.
Install matching nuts.
Use a matching wrench to tighten the nuts at both ends of the shock absorber column simultaneously to counteract torque and avoid damage to the torque sensor inside the test bench.
The installation of the propeller should keep the heading on the propeller consistent with the aircraft's heading. Assemble using matching installation bolts and propeller pads.
Tighten the bolts in sequence.
Attention: When tightening the bolts, tighten them in stages in a diagonal and clockwise direction.
The mechanical connection between the engine and the test bench has been assembled.
Install the fairing and tighten the assembly with matching bolts.
Remove the backing paper from the 3M adhesive, stick the steering gear in place, and press it firmly to bond.
The steering gear rocker arm is installed on the steering gear after calibration of the steering gear travel, and does not need to be installed before calibration.
Through an extension cable, connect the servo signal line to the throttle control signal interface of the test bench.
The high-pressure wire marked with the letter "B" on the CDI control box is connected to the rear cylinder of the engine, and the high-pressure wire marked with the letter "F" is connected to the front cylinder of the engine. Finally, press and install the high-pressure cap in place.
Note: If the high-pressure wires of the front and rear cylinders are interchanged, it will cause the spark plug of the engine to not ignite and the engine cannot run.
Use 3M Double-sided tape to bond and fix the CDI electronic igniter on the end plate of the test bench.
The power plug of the igniter is connected to the BEC power line interface.
The sensor wire of the igniter is connected to the engine sensor interface.
CDI electronic igniter installation is completed.
Assemble the exhaust pipe to the engine exhaust port
Fix the exhaust pipe muffler onto the muffler bracket using accessories and bolts.
Install the oil inlet pipe at the engine oil inlet.
Place the propeller protective cover in the predetermined position and tighten the connection with bolts.
Test bench protective cover installation completed.
The NGH GF60i2 engine installation , electrical and oil circuit connections have been completed. Thank you for watching this engine testing and installation video!
