For Models: PPT-265, PPT-265S, PPT-266, PPT-266H, PPT-280
New Main Pipe Coupler assembly P/N C510000164 supersedes the previous cou-
pler P/N C510000163 for the above models. The new coupler is also used in P/N
P021017320 Shaft/Coupler Kit. The new coupler has a cast post (A) that fits in a cor-
responding hole (B) in the main pipe when the coupler is installed. The post secures the
coupler to the main pipe and prevents the main pipe from sliding off the coupler. Older
PPT-265, PPT-265S, PPT-266, PPT-266H, PPT-280 models will not have a hole drilled in
the main pipe to accept the improved coupler.
To install the new coupler on older Power Pruners, a hole must be drilled 23mm from the
end of the pipe to accommodate the cast post. Measure 23 mm from the end of the shaft
housing as shown, and drill the hole using a 7mm drill bit. Be sure to drill the on the right
side of the main shaft viewed from the operators position to properly align the gear case
vertically when the main shaft housing is clamped by the coupler.
