I want to re-torque the head bolt nuts on my case dc. Was wondering if there is a special kind of torque wrench to do this with rocker assembly bolted on. I can get to about half of the head bolts, but rocker prevents my torque socket to get to the others. thanks, Jim

I just made a tool out of a wrench and a socket, welded them together and it works perfectly. Just keep in mind there is a leverage coefficient when seting the torque.

I have used a aircraft wrench designed to tighten up the jugs on aircaft engines to torque the heads of the 124-164 engines. I use grade 8 nuts on them that are the same size as DC head nuts and I think it would go under the rockers of a DC.

I would just remove the rocker arm assembly. When I had to retorque heads on Farmall M & Hs, I just remove the rocker arm assembly, retorque, replace rocker arms and reset valve lash.

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul ... [Read Article]
