    CAT 420D Not Starting - Electrical Issue?

    Yes, juice is there. I ended up pulling the starter. Two of the four brushes were shot, so I changed them and cleaned everything else up before reassembly. After two years, it fired up immediately! Thanks for the advice!

    CAT 420D Not Starting - Electrical Issue?

    Good thought. I assume that's the single wire/terminal on the lower front of the starter. I tried a positive jumper wire to it from the battery, but the only result was the electric pump kicking on. Nothing from the starter. I'll check with my multimeter. Thanks! If I have 12v when attempting...

    CAT 420D Not Starting - Electrical Issue?

    After a couple years of not running, I am doing some repairs to my CAT 420D to get it back into regular use. Unfortunately, I cant get the engine started. When I turn the key, all that happens is the electric pump kicks on. The starter is totally silent. The battery is charged, the cables have...

    CAT 420D Hydraulic Schematic

    I am looking for a hydraulic schematic for my 420D. I recently hired a local mechanic to remove and reinstall all my hydraulic cylinders to have them rebuilt. When he reinstalled the two excavator swing cylinders, he must have switched up the hoses, so it wouldn't move left or right. After...

    CAT 420D Throttle Problems

    Well, the coastal salt air has finally gotten to both my front and rear throttle cables on my 420D. Can anyone help me with part numbers for the replacement cables? Also, any advice on how to protect the new ones from getting eaten up by the salt? Thanks!

    CAT 420D Won't Start

    Delmer- Thanks for the feedback. To bleed the system, I only cracked the lines loose at the injector inlets and cranked to verify fuel and pressure in the line. I didn't crank it too much... just wanted to see fuel squirt a few times and then pulled the glow plugs to verify fuel in the...

    CAT 420D Won't Start

    Cmark- Good thoughts on the possibility of a parasitic load. Our old compound is currently used as an orphanage, so I have no doubt some young "yellow machine operators" have moved the hydraulic controls. :D I will check that out and make sure all controls are in neutral positions...

    CAT 420D Won't Start

    Hey Deon, thanks for the feedback! Regarding the battery, they commonly refer to the Ah, not CCA, as we do in the states. I checked my battery's specs on the Bosch website and found that my 105 Ah has 570 CCA's. Definately undersize if the target is 1,000 CCA's! I used this size in the...

    I have a CAT 420D (PIN # CAT0420DAFDP26886) that won't start. Here's a little history and a description of what I've tried... My backhoe was shipped from the states to Liberia, West Africa about six years ago. The first few years, it was used lightly in a small mining operation, but sat...

    Broken Retainer Pin in Backhoe Bucket Teeth

    I am having a recurring issue with breaking the retainer pin that holds my replaceable bucket teeth in place. The areas where I'm digging frequently has big rocks/small boulders mixed in with the dirt. In addition to replacement pins directly from CAT, I have also tried "8.8" bolts that I...
