Adjustment Of Single-Cylinder Engine - teching Craftsman DM17-S-T Product Description

III. Adjustment of single-cylinder engine
1. Fitting clearances
Pay attention to fitting clearances among moving parts.
The user is encouraged to adjust clearances slightly using,
for example, sandpaper and calipers, based on his/her own
observations and judgments.
The main parts are as follows:
1.1 Crankshaft and related moving parts
1.2 Camshaft and related moving parts
1.3 Starting motor and related moving parts
1.4 Piston rod and related moving parts
2. Lubrication
Since this product is a metallic mechanical model, the absence
of lubricant for shaft movement may result in higher frictions or
even seizure of parts during movement. The user is encouraged
to apply appropriately more lubricant at shaft assembly
positions, and observe the effect after lubricant application.
3. Noise reduction
Shaft moving parts are made of aluminum alloy and have
anodized surfaces, and there are loose clearances among some
parts, so this product may produce high noise when newly
assembly. The user is encouraged to observe and analyze noise
producing positions, and may also repair with such tools as
sandpaper and file, and apply lubricant to observe the noise
reduction effect.
