Backhoe bh75 dipper rod bent

[kcender]

Good luck with the repair.I am certainly no expert on hydraulics but I used my backhoe with a bent rod for about a year and a half with no damage to the gland so I am thinking yours should be fine as well.All the hydraulic shop recommended was new seals for it which were about 10 dollars.The shop I talked to said it would take about 2 to 3 hours to make a new rod at 65 dollars per hour,this was for machining and welding.It seems like you are getting high prices to me.

I should also add that I have put about 10 hours on the backhoe since the repair and everything is working fine with no leaks.Hopefully yours will do the same.

here are some pics of the guts.. i had to borrow a 24" cresent to open it up. overall it looks OK, i didn't notice any big knicks or gouges but is there something else i should look for?

OK, so where is the bend, it looks straight in the photos. If you can see the bow, now that you have it disassembled, I would maybe try a press to see if it would straighten as it doesnt look bent enought to matter. As long as there is not any dings in it from contact with the trailer hitch, I would put it back together and use it till the seals went bad which might be a long long time as it doesnt look like much.
Might look into an insurance claim of fixing or replacing it also.

here is one of each side, its towards the threaded end..

I would replace the rod and get a seal kit and put it back together. The repair kit for my 580k includes a new bushing for the gland nut, hopefully the Kubota does as well. I wouldn't bother with honing or any of that other nonsense. You could try to have it straightened, it's not bent too badly but only if the cost is not close to having the rod replaced.

I agree, worth a try.

While you have it out it would take about 5 minutes to straighten that with a press and alum shim (and dial indicator if you have one) .....

It may work as seen but you run the risk of damaging the bore in the barrel if it scuffs internally due to the piston cocking sideways...

Found a helpful shop that used a press, alum blocking, and dial indicator to straighten. Cost $30. I did order a new seal kit but am going to clean up and reassemble using original seals. If it starts leaking down the road I'll put the new seals in. There are a couple small nicks on the rod but hopefully they do not affect performance. When I put it back together do I need to pre fill or can I just install retracted and use hydraulics to fill it?

I've never filled them first. Just put it together with a little oil on the seals and then just work the hydraulics to get the air out.

Let us know how it works out!
