Backhoe Thanks folks- I found the problem with my BH dipper.

[IXLR8]

Thanks to folks here giving me the courage and knowledge to tear into my dipper cylinder. Last year I noticed that the dipper on my BH was in a word.. gutless.. it would hardly move any dirt. I depended on my curl and boom to get anything done. When I removed the BH for the winter.. I had left the bucket up about 5' in the air while moving some support blocks around... I looked up from moving the blocks and I could watch the bucket drop!! It was dropping about 4" per minute!! I have 355 hrs on the tractor, but this is a Kioti replacement cylinder with about 30 hrs on it!! I have new seals from Martin Fluid Power ready to go in... it will be a few weeks, after I fix up our dirt road from spring mud season, before I pull the rear blade off and put the BH back on to verify it is working properly. Based on how weak my loader is, and the fact it drops about 3" per hr... I think it will be time to pull them apart in the not to distant future. I have a feeling I am going to be getting pretty good at this too soon.

Thank you again to all who have provided support and guidance in these forums.

Hey Jim,

My cylinders are holding much better since the rebuild. Thanks to Andy of Wayne County Hose for all his assistance during the process.

Please post pictures as you go.

This post is over a year old but hope you remember.

Jim, Do you remember the seal part numbers for your dipper stick cylinder. Mine really doesn't drop that much on the KB2375 but it does seem a little gutless. If I was going to pull the cylinder apart to check the seals, I might as well have new ones to use when I put it back together.

Thanks for the possible help.

Vic, short answer... I don't remember. I am out of town at the moment... but when I get home later in the week I will try to remember to check and see if I have that info in my records. Do you have the BH manual? The info is in there but it takes a little decoding/matching to line up with MFP's numbers.

Jim, I have the operator's manual that came with it. I'll check and see if it has some numbers that I can work with.
Thanks,
Vic

Vic,
I have 2 part numbers I bought for the BH. The seal description is listed as:
Metric Urethand U-Cup Symetric
Smaller one- MSUC-035x045x06.0
Larger one- MSUC- 050x060x06.0
The part numbers and descriptions are from Martin Fluid Power, I don't remember which one was for the dipper.

These are for a cyl with a 35mm rod and 60 mm bore......

No, they are for 2 different size cylinders, I just don't remember if the dipper has a 45mm bore or the 60mm bore.

Oh, I see....you only changed the piston seals.....Got it....
