    bobcat t740 hydraulic oil

    I did a bit of searching online to see people's opinions on alternative hydraulic oils for bobcat skid steers. Not too many of the conversations comment on recent machines. Curious if anyone has experience using aw46 hydraulic oil in a more modern model like my t740. I put Mag1 aw46 in my new...

    zexel injection pump return fitting stripped threads

    Howdy, today I accidentally yoinked on the return fitting a little too hard and stripped the threads. Got the fitting off, it's m12x1.5. Anyone foresee an issue putting a helicoil in there? Figure I'll run a vacuum as I drill and tap the hole. Is it the return fitting, so hopefully if metal...

    bobcat t740 power bobtach solenoid connector loose

    Howdy, I'm fixing up some things on my recently acquired 2018 t740. By the looks of it, a portion of the pump drive belt came apart and tore up the electrical harness that goes to the fuel level sender and the power bob-tach solenoids. While removing one of the solenoid connectors, I noticed it...

    Bobcat t740 fuel level sensor replacement

    Has anyone ever replaced the fuel level sensor on a t740? The service manual says to pull the engine and pump assembly. Surely there is a more crafty way??

    O-ring boss caps

    Howdy, I've recently acquired my first machine that uses ORB (a bobcat skid steer). I like to have a cap and plug kit on hand for when eventual repairs happen. All the kits I'm finding online only have ORB plugs (male thread), with no caps. Why is this? Where can I find female caps? All the...

    deere 35g vs 50g wedge coupler ears

    Hello, could anyone confirm whether the quick attach ears are the same on the 35g vs 50g? I've found quite a few sellers of the quick attach ears for the 50g at a cheaper price than others listed for the 35g. Planning on retrofitting some buckets to fit a 35g coupler. Thanks, John

    pc35mr-2 sticky travel lever

    I have a couple symptoms on my pc35mr-2. The right travel stick on my pc35mr-2 isn't smooth. Occasionally the travel beep alarm doesn't stop beeping even when I've returned to neutral.

    bucket quick couplers

    Howdy, I'm searching for a manual quick coupler for my komatsu pc35mr-2. It has 35mm pins. Do you know of any affordably priced ones? It seems TAG buckets are popular in my area, would be nice to score one of those but it's difficult to get pricing on them. Another option is buying a used one...

    How would you remove these bushings? Komatsu pc35mr

    Doesn’t look like there’s a stop shoulder in the bore, so they could likely be pounded down but that does seem like a lotta work. I’m not confident enough with a torch to cut them out with gas. Any other cutting tool you’d recommend? ID on the bore is 100mm.

    Hey, I’ve got a confusing issue on my trackhoe. It’s a kubota kh70, uses the same sprocket and tracks as a kh90. The right track is able to rotate one revolution of the sprocket and then it locks up. I turn it backwards and it does one revolution then gets stuck. Forwards one rev and stuck. I...

    Isuzu 4jb1 knocking sound

    https://photos.app.goo.gl/BZaB5nFMsPrnB5FW7 My engine has a pretty constant knocking sound that I need help diagnosing. I tried one-by-one loosening the fuel injector lines to see if it was one cylinder making it, but I didn’t isolate it to one. I did a valve clearance adjustment and that...
