7-8 Ton Machine Swing or Fixed Boom
I have been doing some preliminary research on machines. I have noticed some have swing booms and some have fixed booms like large excavators. Is the swing boom worth the cost? We currently have a 307SSR with the offset boom and it does come in handy every once in a while but its 4 more pins to grease and another cylinder to worry about. What are your thoughts?

Case 15 maxi track motor problem
Hi All
I recently replaced the face seal on the track motor. All was fine for a few hours, then the casing plate ballooned out and cracked.
The motor is being pressurised by the hydraulic fluid. There is no case drain on the motor, just 2 lines.
Does anyone know how the motor is getting pressurised, and how do I fix it?
Many thanks in advance

boom swing not working right
I have a IHI 35N. The boom swings to the right like normal but when i try to swing it to the left it just creeps real slow. All of the other hydraulics seem to be working like normal. Does it sound like i have a problem in the control valve or does it sound like something else? Any help would be much appreciated.

Case CX14 low/no hydraulic power
Hello all, I'm in need of some help from the experts on this forum. My brother has a 2004ish? Case CX 14 mini which has sat pretty much unused over the winter and when he went to use it the other day it has barely any hydraulic power. We have a repair manual, but I'm not very familiar with hydraulic systems, so here I am looking for help.
The bucket will uncurl a very minimal amount and the house will try to rotate, but that seems to be about the extent of what it will try to do. The arms/blade/tracks don't seem to do anything. Since some operations will move a little I don't believe it to be the locking switch in the arm rests.
I've checked the strainer filter and it wasn't clogged and there didn't seem to be any debris in the hydraulic tank. Pilot valve tested and was right at the 500 psi called for.
I've going to check the other pressures at the main control valve. Is there anything else I should check or test before that? I'm at a real loss as to how it worked fine in the fall/early winter and now doesn't really do anything.
Thanks in advance for any help!

Scissor blade on thumb
Has anyone bolted a blade to the thumb cut smaller trees ( 4-5") to size when stacking brush piles? Seems like a bi-pass blade/ bucket arrangement would work. Have no problem breaking them but not always clean or where needed. Pictures or ideas please. Thanks.

Anybody mount a quik tach on a Deere mini-ex?

Hydraulic fluid
The last time I changed the hydraulic fluid in my mini I used Chevron Rando 46. It's about time to change it again and I already have a bucket of Napa AW 46, and the Napa stuff is only $40 per 5 gallon bucket and not to mention they're right down the street from me. Since hydraulic fluid is the most important fluid in a mini I was wondering if anyone has any experience with the Napa stuff and if it's any good. My mini specs ISO 46. What does everyone else put in their minis?

takeuchi 53fr cab interference system
So I have a tak 53fr. Im having trouble getting the cab / bucket protection system to let the boom rock back, when boom is all the way to the right. It had been acting up a little like when left for a couple of days it would take a little fidigiting with the switch to make it work right.
Today it quit working right all together, switch does nothing.
What are my chances that I have a bad switch, and how does the system work? A latching relay? Could I have a broke wire somewhere? Are there any diagnostic tests?

Kubota KX121-2 Hydraulic pump
Anybody out there know where to get a cost effective replacement pump for a KX121-2. My machine is is only getting to 1500 psi on the right track drive, boom and bucket. I swapped the pump pressure lines and the low pressure problem followed to the left drive, arm etc. I was looking at the parts catalog and pricing the valve plate, pistons, cylinder block, seal kit and the price is getting close to a plug and play unit from Kubota.
Thanks
Thanks

Searching for mini excavator
Hi Guys,
I'm very new to the site. I'm looking for some help in picking a mini excavator. Our company has been in the landscaping industry since 1971. We primarily do landscape and hardscape installations. We have always run either bobcat or kubota equipment. We are in the market for a mini excavator. We had a bobcat 331 mini and sold it. I am looking for something in the 7000-8000 pound range. I found a slightly used cat 303.5cr E in my price range but a few of my buddies have said they have run the CAT minis and they seem to be under powered. Can you guys provide some insight? I will also be demo-ing a Bobcat E26 (smaller scale, weighing only 6k) but my supplier is saying that machine will do everything we need it to and we don't need the 8k machine.
My main question is.... For those of you with CAT mini excavators, do you find them under powered compared to other machines? And for those of you with mini excavators in the 7K-8K range, What made you decide on the specific machine you did?
Thanks in advance

Cat 303C CR issue, pics and video inside!
2007 Cat 303C CR
Engine is the Mitsubishi S3Q2-E1 3 cyl.
This is the only mini excavator that I have driven, and my issue is first that I think that i shakes and rattles quite a lot at idle and low RPM. It rattles so much so that I have to drive at a pretty high RPM, but then the hydraulics gets too sensitive and quick in its movements, so I can seem to get any flow in my digging.
If you look at the video clip you can see the rattle, and you can also hear my other issue. Is the high pitch metal rattle that sounds like a loose washer or something like that.
I cant find anything thats loose or anything!
The engine mounts looks fine to me, so I dont really think that they are my problem, but I can not guarantee that.
Does this engine have three or four engine mounts? I have only found three...
Check pics and video and please give my a hint on where to start searching for my problems! :-)

bobcat 334 hydraulic pump
I have a bobcat 334 that has a cracked hydraulic pump housing. I am not able to locate parts for a rebuild other than the seal kit (which I already did). Bobcat says I need the upgrade pump to get any parts. Does anyone know where I can find one of these pump housings (its the inner pump) and what is the difference between the old and upgrade pump? SN is 516712312. Thanks.

Volvo EC25 and Kubota KX41-3S - Too many hours? 1.5 or 2.5T ?
Hello
My name is Filipe Silva, i'm from portugal and i want to buy a small excavator to move some land (Gardening), and do some little excavations to build fenses to my new house. I just sell a backhoes Case 580 K (Too big to my work) and i think a small compact excavator is better to me.
I also have a small "dumper"
i've see a 3500 hours Kubota KX41-3S (1.5T) 10,145.73 USD with only a cleaning bucket and a Volvo EC25 (2.5T) with 3 Buckets with 6700 hours 10,823.95 USD and the engine rebuilded.
I tryied both and both are strong without leeks and good tracks (more than 80%) with only smalls looseness in the attack (normal for the age).
Is 6700 hours to much? I think i will need something like 200 hours of work and then sell the excavator. Is 1.5T enougth or is better have a 2.5T Machine?
Thanks for your help

Cat 301.8 No Start No Crank
Ok, I am in need of some real help. I have a Cat 301.8 that will blow the 10A fuse for the engine whenever you try to start it. I have disconnected the starter ignition wire to see if the starter was bad, but still blew the fuse. I have checked the fuel shutoff for a short, along with the relay in the blower motor housing. I have used a tracer from the output side to the engine fuse and only found the trace to stop in the blower motor housing. Can someone give me a hint to where to go next, and/or where the main relay panel is and where I could get a wiring diagram of at least the Starting Circuit? The only thing I can think is a rub / short somewhere in the canvas covered harness. Has anyone had this problem and what have you found.
Thank you in advance,
Tim Smith
