piston/rod question

Recommended Posts

dav

again working on the b&s model 19 and using the out of production manual.

on page 5-4, fig 545, the last 2 illustrations seem to indicate the rod can be assembled to the piston either way. is this right?

I put the rod on the piston the way I think the book is telling me but it is opposite of the piston I pulled out of the extra motor.

I am using a NOS piston and a NOS rod that I scored. I still have the old piston but not the rod. have no idea why I took them apart or what I did with the rod; I tore down the motor about a year and a half ago

You assemble the piston and rod so that the notch in the top of the piston and or the "X" on the piston pin boss face the magneto end of the engine. Then install the rod so that the assembly marks on the rod and the cap also face the magneto end of the engine. The rod should only go on the piston the one way. Apparently in the pictures you reference some rods have the marks on the carburetor side of the rod or on the other side but MUST always be placed toward the magneto end of the engine.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
