In Reply to: Cheap power upgrade for diesel tractor ? posted by Chris Young on December 01, 2006 at 09:01:50:

It's been done for many years. When I worked at a Deere dealership, we did it with new and used tractors that had cold-starting and/or skipping/smoking problems. My old International Harvester manual from 1960 - states in regard to diesel timing - to advance a few degrees if better starting and more power is needed, and to retard timing if a quietier engine is desired. Also, in automotive stuff, especially diesel engines with timing-chains, like 6.2 and 6.5 GMs. When the chains stretch, the injection pumps run late, and bumping up the static timing can sometimes make a huge difference.
One thing to keep in mind though, is the difference between changing static timing - usually by physically moving the injection pump or drive gear, or changing the timing advance - which usually requires an internal pump adjustment. Sometimes you don't want the initial advance bumped up, just more advance at the high end - and in that case - changing static timing is not the remedy.
