I've been getting a lot of questions on 3116 Cat Diesel Engine problems. The one stumbling block is the tooling you need to repair these model engines. After the basics like fuel supply and electrical issues are taken care of the next step is replacing injectors and other related tasks.The tools required for tuning up these engines come in a kit and costs over $2000.00 in my part of the world. These tools must be used to get this engine synchronized, timed and set up properly.
If you have access to the tools that's great, a manual accompanies the kit. There is a learning curve with setting up the 3116 but do it once and you'll understand the concepts behind the injection system.
There are glitches with the 3116 are usually the same and I have posted them as they happened on this blog. The exhaust valves are weak and it seems like #5 exhaust valve is a weak spot. Keeping the valves set is a good practice and prevents a tight valve and overheating.
If you use the search box above you can get more details on tune ups and repairs. There are specific rebuild procedures covered as well.
