Old Iron: The Difficulty Of Electrical Repairs On Old Equipment.
Published at : 23 Dec 2025
It's time to tackle the electrical problems on this old Case 170B excavator. Several things need to be fixed. 1. The temperature gauge. Especially being an air cooled Deutz diesel, I need an accurate gauge to know that the engine is cooling properly. 2. The oil pressure sensor. With any engine you need to know that the oil pressure is adequate or you will ruin the engine in no time flat. 3. The hour meter. This is important for future maintenance. I need to know when to do the fluid and filter changes. 4. The high speed drive. While not an absolute necessity, this machine tracks very slowly, and I have large distances that I will need to cover for the jobs I want to do around the farm. Fixing this is definitely high on my list.
