Assembling a running Saito FA-270T from a box of parts?


New $40 adventure! Wonder what it will cost by the time it's all put together? Parts for the older style 270T are near impossible to get. Might have some custom parts and modifications on this one.

Yeah, so far 1 cracked cam cover, 1 messed up, drilled out glow plug hole, 1 broken prop hub and 1 cracked rocker arm bracket.. and I'm not done going through it yet.

So, it turns out I have almost 2 whole engines in parts here. 2 different models of the FA 270T. Not sure yet whether parts are interchangeable, likely some are. Pictures shows differences between the models. It's pretty clear the casting improvements made over the years.

Just a quick note in reference to the FA-270t engines. Make sure the connecting rods have the bronze bushings for long life, the rings are the same part number for the Saito FA120, the rocker covers utilize the same gaskets as the FA-120, and the rocker arm bracket is also the same part number for the FA-120.

The main issue I had is shown in your photo view #9 of the right and left spur gear cams. The left spur gear cam has a line stamped 90 degrees away from the dot reference. Do not use the dot reference. When the right cylinder is at TDC, the cam gear dot must go straight into the crankshaft gear. Then rotate the crankshaft 360 degrees until the left cylinder is at TDC. This time the line on the spur cam gear must go straight into the crankshaft gear. Also, make your own gasket for the cam gear housing at least .oo6 " thick. I think what happened here is that many left spur gears were made in error and rather than trash them, they were re-stamped with a line for correct timing. I also had to custom fit the valves (lapping) to eliminate leakage. The new rings had no leakage what so ever. I purchased the bearings at McMaster Carr and also "0" rings for the carb base and intake manifold.

I just finished two of these engines and I think they were the second generation.

FYI,
