Going through the engine, changing fluids, hoses, coolers and heat exchanger. While checking the fluid level in the injection pump before draining, I discovered the oil level screw was stripped….and the injection pump oil was very diluted with diesel. The hole in the boss for this screw seemed to be about the size of an 1/8” NPT fitting. I covered the tap in grease and proceeded to slowly tap the port. Long story short the whole cast aluminum boss broke off from the injection pump. It appears one of the previous owners had broken this boss and epoxied it in place.
I cleaned all the epoxy residue from the injection pump and broken piece and finished taping the piece in the vice. Then cleaned everything with acetone, epoxied a nipple into the newly threaded boss and epoxied the piece back onto the injection pump. For the future I’ll just use a SS 1/8 NPT cap for checking the fluid level. Should hold fine. Epoxy used is JB Weld KwickWeld.
