Backhoe Need info on parts for Mahindra 4550B Backhoe

[Old Salty]

Had a pine tree fall and hit my backhoe attachment with just enough force to bend and crack one of the 90 degree elbows. Luckily there was a power-line run to stop the tree from doing more damage than it did. I attempted to remove the flared fitting from the elbow with no luck and looks like I will be needing to have a new fitting welded on. I'm not a welder or highly experienced with hydraulics, but am guessing that I will need to take the cylinder apart, also guys on youtube saying to replace all soft parts when repairing cylinders. I have some questions on this.

First this is an ANBH86A (4550B) model backhoe, data plate states it was built by Ansung Industrial. Looking at the 90 degree elbow and fitting I can not tell if the flare fitting is screwed in or if it is actually part of the elbow. Thought maybe someone else here has had work done (or done work themselves) on this design could shed some light on this. Also unsure of what threads I'm looking at they seem to line up on an 18 tpi.

Second, what are others thoughts on replacing soft parts? There's no leaks on the shaft and hoe was functioning as it should, so if I'm careful when disassembling, can I get by with carefully reassembling it as is? I've had a string of things breaking lately and money is tight... If I need to replace seals and such, where is best place to attempt to locate parts? It seems that finding repair parts on Mahindras can be quiet the hunt.

The elbow is threaded into the piston

Do you mean the top portion of the elbow? Because the small vertical pipe looks like a weld.

 

[Peter 315]

Yes the top portion should look like this....

Thanks, I will give that a try in the morning.

You can try New England Tractor and then go to Mahindra parts (might need to do it twice) and then use the model search feature, once that comes up type in 4550b and hit enter.

Wondering if you can drill out the busted piece from the end of the elbow and either tap it and use a pipe to JIC straight nipple or weld a nipple onto the broken piece. I don't think it's like the pic Peter posted, looks to be one piece but I can't tell for sure.
If you go the drill route, extend or retract the cylinder (can't tell which end is damaged) before you do anything, once you're done move it the opposite way to blow most of the crap out. and fish around with a small magnet to remove what wasn't forced out..........Mike

Yeah my son and I tried to break that fitting loose yesterday, no luck what so ever. I had tried drilling some to get a bigger size easy out in there previously(it would have been either a 4 or 5, but hit the back of the elbow before getting a good bite) it looks like it may have been a straight male to male fitting but made no sense to me that there was no nut shaped flange to back it out. Do you know what thread Mahindra supplier (Ansung) may have used? I am going to try draining the cylinder and heating the fitting to see if it is like the one Peter posted. If not then either tap threads or last option see about getting a new pipe or bung welded on.

I wonder if it was a fitting like this originally, in a 90 tho:
Your probably better off just cutting the busted fitting off, weld a straight hyd coupling on and using a 90 NPT to JIC elbow.
Don't forget to extend the cylinder so you don't melt the seals............Mike
