engine specs (measurements)

[BLES]

Anyone have the specs for the FE290 engine? I'm looking for bore, rod end diameter, crankshaft journals, etc.. I found the torque specs using the search but can't find the rest. Trying to determine if I can use an undersize rod, if I need to bore, etc.

Thanks in advance.

Cylinder Inspection
• Inspect the cylinder wall for the presence of any scratches, the
cylinder exterior for any broken fins, and for any other damage.
If the cylinder has non-repairable damage, replace the cylinder block
with a new one.
• Using a cylinder gauge, measure the cylinder bore in the longitudinal
and latitudinal directions at the locations given in the diagram on the
right.
Cylinder Bore Service Limit (maximum)
FE120: 60.067 mm (2.3648 in)
FE170: 66.067 mm (2.6011 in)
FE250: 76.067 mm (2.9948 in)
FE290: 78.067 mm (3.0735 in)
FE350: 83.067 mm (3.2703 in)
FE400: 87.067 mm (3.4278 in)
Cylinder Bore Roundness (maximum)
Service Limit: 0.56 mm (0.0220 in)
If the measurement shows that even one area of the cylinder has a
greater bore or roundness than the service limit, bore the cylinder to
an oversize or replace the cylinder block.
The oversize piston and piston rings come in + 0.50 mm (0.020 in)
oversize.
1. 10 mm (0.394 in)
2. Center Point
3. 8 mm (0.315 in)


Using an inside micrometer, measure the bore of the bearing area of
the small end in several places.
Connecting Rod Small End Bearing Area Bore Service Limit (maximum)
FE120: 14.042 mm (0.5528 in)
FE170: 16.047 mm (0.6318 in)
FE250: 18.051 mm (0.7107 in)
FE290: 19.051 mm (0.7500 in)
FE350, 400: 20.051 mm (0.7894 in)
If the measured value is greater than the service limit, replace the
connecting rod with a new one.
• Mate the connecting rod cap to the big end of the connecting rod and
tighten the connecting rod bolts to the specified torque. Make sure to
apply engine oil to the threaded portion of the connecting rod bolts
before tightening them. (Refer to the section on Tightening Torque
Specifications.)
• Using an inside micrometer, measure the bore of the bearing area of
the big end in several places.
Connecting Rod Big End Bearing Area Bore Service Limit (maximum)
FE120: 26.052 mm (1.0257 in)
FE170: 29.052 mm (1.1438 in)
FE250: 34.067 mm (1.3412 in)
FE290: 35.567 mm (1.4003 in)
FE350, 400: 37.567 mm (1.4790 in)
If the measured value is greater than the service limit, replace the
connecting rod with a new one.
• Insert a bar each, measuring approximately 100 mm in length and
almost the same diameter as the respective bore into both the big
and small ends of the connecting rod. Then, set the V block and the
dial gauge as shown in the diagram in order to measure the bend
and twist of the connecting rod.
If the measured value is greater than the service limit, replace the
connecting rod with a new one.
Connecting Rod Bend and Twist Service Limit (maximum)
Service Limit: 0.15/100 mm (0.006/100 in)

Exactly what I was looking for. Thanks!
