    Cat 914G rear axle removal question

    Thanks Nige, I have never worked on One before. I did notice every procedure called for the axle to be removed but had a slim hope for an easier job. Looks like I’ll try to limp it a few miles to a trailer and do it at the shop. Thanks for responding

    Cat 914G rear axle removal question

    So the rear axle was making some noise, drained the fluid and found metal flakes and a 1” long tooth from one of the gears. The machine is in the hills and how big of a job am I looking at? It is the rear oscillating axle so can I get away with removing the tires and axle tubes? Will that allow...

    Cat 914G hi/lo not working

    Forgot to post an update. The loader is fixed it ended up being a faulty ECM and the transmission speed sensor. Replaced them and all is good! It was nice that the smaller loader ecms came pre-programmed.

    Cat 914G hi/lo not working

    I have never looked forward to electronics! I will start the ecm codes in the morning. I ran out of daylight. Re reading the manual for now and will start fresh tomorrow. Thankyou for helping out!

    Cat 914G hi/lo not working

    Thanks for the update. I have the switch removed and with the key on, F747-or-18 has 4.9 volts and is located on pin 1 The 742-or-18 at pin 2 has 0 voltage. And this is the wire that is suppose to have 24v with key on?

    Cat 914G hi/lo not working

    Yes im good on voltage across batteries. Might do some creative wiring. My Only concern is sending to much voltage to the solenoid? IM assuming its 24 volts?

    Cat 914G hi/lo not working

    Picked up the speed sensor and solenoid today. Got them both installed and no change. Although I was able to fully test the old solenoid and it was burned out. The problem i think is in the wiring. The hi/lo switch only has 4v of power in the cab, and the plug on the hydraulic solenoid is...

    Cat 914G hi/lo not working

    Thank you for sharing that. So the sensor that is broken is the engine speed sensor (I was wrong calling it the transmission one). But I also located the transmission speed sensor and found it unplugged. It appears that those both send signal to the ecm. I will get a new one on Monday. I also...

    Cat 914G hi/lo not working

    Was looking around for possible damaged wires and and noticed the transmission speed sensor was broken in half. I tried to push the barbs back in but it eventually snapped in half. I will need to get a new one since this one was most likely damaged during the engine install. Do you think...

    It also looks like the factory plate displays the turtle/rabbit emblem. I noticed its in a different location than your picture but still portrayed as being far right.

    Cat 914G hi/lo not working

    The machine is new to me and needed a new engine. I got done putting in a new one now IM running it to find other issues it has. I assumed it has hi/lo since the switch is there and hot..all of the other options have blanks where the switches would be. Like the ride control and other options.

    Cat 914G hi/lo not working

    Hey, I have a 99 914G and its stuck in low gear. Nothing happens when you switch to high. I checked the voltage at the switch in the cab and it seems to be working fine. I dove into the manual but cannot make heads or tails of the wiring schematic. I also cant locate the hydraulic Solenoid that...

    Fuel leak on older D5

    So if that hose is made for bleeding the fuel lines. Would that mean a ball valve or something like that has failed? I have opened and closed the top air screw a few times, in hopes of it resealing but it still leaks.

    Fuel leak on older D5

    Rehashing an old post. My D5 94J is having the same issue with fuel coming out the drain hose. Question is: do I need to pull the injector pump to fix this leak? Also posted a picture. Thanks!

    Komatsu pc120-3 undercarriage interchange

    Hey, I have a pc120-3 and it’s time to put on new sprockets and track chain. Problem I’m running into is the 120-3 chain and sprockets have been impossible to find state side. All I can find online is Chinese parts. Called my local komatsu dealer and they said parts have been discontinued. Does...
