Bottom end rod caps

Postby Command52 » Thu Mar 22, 2018 10:30 am

I'm getting ready to pull the rods out of my bottom end and I'm not sure how to mark the bearings and caps and rods do I need to mark which way the piston comes out, and what to I mark with hammer and punch. I'm getting it ready for machine shop and they are putting it together . Thank You

You can mark them with a punch, be sure they all go back in the way they came out. You can use a center punch and mark the first one with one punch, 2nd with 2 punches etc. You can punch your main caps and block beside each other so they match. Same way with rod caps. TAKE PICTURES BEFORE TAKING IT APART THOUGH!!!

:Dito: That's the way I found them. There might be some exceptions but I've not heard about it (Once I had to replace the #1 domed piston/rod assy and the only one I could find was stamped #3. I'll bet the guy who takes it apart the next time will wonder how that happened!) :lol: :hattip:

I might ad that this statement applies to ANY project you are tackling, unless you are an expert. With digital, there's no excuse for not taking more pictures than you think you need. You can always hit DELETE, when you are done. Or better yet, post a HOW TO with your photos, so others can benefit from your hard work! :D

Hi,
Below is the Cub service manual. The engine is in section 1. I would read it before working on the engine.

http://www.farmallcub.info/galleries/ci ... actors.asp

The connecting rods and caps are usually stamped on the side with numbers for the cylinder they belong in. The numbers have to face toward the camshaft side of the engine, like was said above. :)

I used a piece of cardboard and traced the oil pan, marked the "Front" and then labeled each cylinder.
Stick the bolts through the cardboard to keep track of where they came from. The rod caps are notched on one side so you can line them back up.
