/// Another Bunch Of 273 Commando Rebuild Questions? ///
Need some help identifying rod and crank bearing sizes.
The first picture is the rod bearing.
I believe it was manufactured in 1977, obviously been replaced sometime in the past.
ID on the bearing - T 11 6 Clevite 77
What is the bearing size?
The second picture is the crank bearing.
Still in pretty good shape.
ID on the bearing - TC 10 6
What is the bearing size?
Where is the best place to buy new bearings?
I'm going to order a 220-grit ball hone to deglaze the cylinders for new OEM rings.
Will a 220-grit work or should I get a 180-grit hone?
I have been cleaning up the crank journals with 400/600/1000 grit sandpaper.
They are cleaning up pretty good.
Thanks for the help
