Bringing a 1212 back

Post by 91dodgecummins350 » Sun Feb 04, 2018 9:25 pm

Hey everybody, I started working on a 1212 and happened to stumble upon this forum and decided to join after seeing how many helpful people there were on here!

Story about the tractor: My grandpa bought a farm in '92 and the tractor came with it. He used it on the farm as the main tractor for many years until blowby brought it to an end. The tractor was parked and at some point the rain cap got removed and water met cylinder #1. I needed a project tractor for my final semester of College and my grandpa was all for it.

The current plans are to overhaul the engine and fix the powershift (just up and quit all together one day). I will update this every so often with whatever progress I've made.

Got the tractor split and tore down. Engine was locked up but I didn't have too much trouble getting the pistons out. Block, head, crank, and rods are off to the machine shop, hoping for good news on those!

On many of the other engines I have gone through as a rule you don't reuse headbolts or studs. What is the consensus on these as I am unable to find new ones? There are 2 of mine that have some surface rust but other than that they all look good

Provided there is nothing visibly wrong with them (i.e damaged threads) they are to be reused. Clean the threads (a wire wheel is excellent for this) and apply a light coating of copper grease.

It's more modern engines which are designed to be as cheap and lightweight as possible where you can't reuse head bolts as they're designed to stretch and should normally only be tightened once. David Browns are built with heavy duty parts that can be kept in use for almost any length of time, an era which has sadly passed!

Thank you for letting me know! They just don't build them like they used to....
