    Throttle Position Sensor Needed

    I have a failed TPS. Hitachi Sera 483-06 C8714 I've looked everywhere for one and I can find used ones on ebay or close other model #s.... Anyone here know whether this has a new upgraded model # or where I can source a new one?

    CAT 312b threw track, what's this bolt

    Yep, I know it's out of the ram and the need for the groove. However, we've never had a track issue with this unit. I backed it off and backed it off and never got grease out of the recess chamfer threads on the bolt. I had to back it out all the way out to get grease from the idler push...

    CAT 312b threw track, what's this bolt

    Yes, I got about a half tube of grease when we pushed the idler forward. Seemed the usual typical straightforward issue. Track is on machine but idler is well recessed.

    CAT 312b threw track, what's this bolt

    1998 CAT 312B, 6500 hours. Been running tracks loose for years and never had an issue. The short backstory is I should've grease pumped them up a little....three days ago. So it threw the track bright and early today on top of a berm for detention pond. Little room to work and a deadline...

    CAT 312B Swivel Joint

    Pretty sure my 1998 machine with 6500 hours is experiencing a swivel joint problem based on forum research. The tracks experience mysterious travel and function problems on turns but not in a straight line. Drives are strong and straight on straight travel or incline. No leakage underneath...

    2003 Komatsu PC150LC-6K

    Looking at this used excavator. Serial #starts with a K and its LC-6K U/C looks good from what I've seen. 5600Hrs, Hydraulic Q/C, Hydraulic Thumb, 36" bucket good condition, sheet metal condition is good as is cab. I know this will have Cummins 4BT 4 cylinder turbo and there have always...

    Semi-Old or Semi New?

    Is an older CAT/Komatsu/Hitachi/Deere/Volvo excavator, from say 1999-2003 with less than 5500 hours on it a better deal in terms of reliability and longevity than say any of the above with over 10,000 hours and vintage 2006-2010? Thoughts on this? We've got a fairly strong year here in 2016...

    Add Hydraulic Oil CAT312B 1998

    Also....the 315 next to it, sitting similar, on same slope had oil in its glass. I used it as my reference point. Not exact but pretty close to the same setting.

    Add Hydraulic Oil CAT312B 1998

    Nige, thanks for your response and concern. I had the machine in that configuration roughly but it was not completely level. The boom/stick and bucket were set like the diagram. The off camber setting could have contributed to the hydraulic sight glass being low but I saw none in it. I would...

    Add Hydraulic Oil CAT312B 1998

    I was doing a machine inspection on this excavator on Friday and noticed that its low on hydraulic oil. It had all fluids changed before I purchased it and then it was vandalized heavily before I needed to do again. When it was repaired they did a complete fluid change on it. I have the...

    Cat 312b

    This machine apparently has a two speed issue. It makes up its own mind when it will engage high speed. When I started it up, rabbit mode was on. It traveled in rabbit mode and then I switched it back out. The mechanic was up front and pointed this out to me. Is this a common issue? Thoughts?

    Cat 312b

    Looked at a used 1998 machine with 4800 hours. Machine is in good condition. What are major problem areas with that machine, i.e. weaknesses or components that have too short of a life. Also, this one had something that I had not seen before.....a power front window. Thoughts on that?

    PC150 Evaluation

    Second owner has had it about 1000 hours. He's an O/O and looks to be good on the maintenance side of things. The rest of his stuff is CAT and older and he maintains those. He's got to get rid of this payment and will be down to a 304C mini as his only excavator. The rest of his stuff is...

    PC150 Evaluation

    Ok, I'm going to go back and look at this machine again. Can you all point me to things I should inspect closely on it? I've no idea on the machine where things that are important to check are. This machine purchase will be the first large (mid) size excavator that I will buy and the first...

    PC150 Evaluation

    Checked into this machine this morning. Attached are some pictures. Let me know what you all think. PC150-6, 2000 Year, 5900 hours. I've searched long and hard for a good used 13-15T machine. The biggest concern I have is the leaking boom cylinder. I can have my dealer come out and look...

    Problem with KOMATSU PC 150 LC

    Reply to old thread but I am talking about Komatsu and I can't start a new thread yet. I am looking for a used Komatsu excavator. I already have a PC55 and need a bigger machine.
