B rod orientation

Inabucket · Apr 16, 2012

Just got a B Allis and the head is removed rods/pistons and sleeves in a bucket. All the parts are there although I"ll be installing new sleeves/pistons rod bearings and all gaskets. Now to my question::: the pistons are already off of the rods and noone marked front on the rods, but They are numbered. are these rods installed the same as most rods with the bearing locks toward the camshaft? Thanks for your time

no, 2 and 3 are installed backward from 1 and 4. If you install them wrong, they bind on the crank side wall. WHen you try to install, it is obvious if they are backward.

i mean the rod will be too far to the front or rear and it will drag the throw of the crank and not be centered on the journal.

All that good info and much more is in the I&T service manual, AC-11. Pics detail rod installation.

I do not know if the "B" is the same as a WD-45..but, on them, you need to know which wrist-pins need to be off-set and which way to get them to be "Centered" in the pistons, once installed...

Got this ole gal running after getting spark from the magneto, rebuilding the carb and of coarse the engine. Now I need to rebuild the waterpump or buy one. Again thanks for the info on the rods ( and yes they were self explantory once ya started putting them in the engine)
