Cracked hydraulic tank

[honey_badger]

Morning all,
I have finally found the source of the leak on my jz70, the hydraulic tank has a fair crack in it where there is a bracket welded on to it. Now I’ve no problem with cleaning it up and welding it, the only thing is I don’t really want to explode myself or the tank
Any tips from people who have done this sort of thing before? Drain and keep blowing with compress air air line inside to keep fresh air moving? Fill up with argoshield/something inert?
Any advice appreciated.

You purge with argoshield and keep it filling/exiting as you weld.

I'd recommend trying a resin product first. Welding is tricky- a lot of cleaning and prep. I had great success with Resimac 104 recently. Its designed to seal leaking transformers without draining.With a large enough area patched past the crack I'd say it would hold it sufficiently to stop further crack propagation. Drill the ends of the crack before you resin it.

British manufactured also.

Doesn’t sound like a bad shout but surely you have to clean pretty well to get a good bond with the resin?
There is also a bracket hanging off where the crack is with the air filter and a hydraulic filter mounted on it which is probably bouncing around a lot spreading the crack?

is the tank coming off or are you going to try and repair in situ?

It's designed to seal leaking transformers without taking them out of service. Drain the oil and degrease the outside is all I did.

I’ve welded plenty of tanks and pipes etc, drain the oil, clean the crack as best you can, possibly run a flame over it to burn/encourage the oil out of the joint. Then weld it up. Hydraulic oil seems to be one oil that you can almost weld through if some does appear and you’ve got enough heat in the job, unlike gear oil, that’s bastard stuff!
Obviously vent the tank well when welding. And make sure oil cannot run towards the are you are welding.

Try and do it in situe if I can the access to the crack is good

I keep trying to post a photo but it doesn’t seem to work on my phone

(Scratch that it worked this time)

Cut the strip off, ground down weld and filled all cracks then welded a fishplate sort of thing over the area and welded the bracket holder back on, hopefully spread any stresses now and won't happen again.
Doesn't leak either so I'd consider that a success

Why do they hang things of tanks

Air filter and hydraulic filter bouncing around on the side of the tank.. daft isn't it lol

I discovered a cracked hydraulic tank during a routine inspection. The crack appears to be along a welded seam, and there's evidence of fluid leakage. This could lead to a serious failure if not addressed quickly. I've already drained the remaining fluid to prevent further loss and contamination. The tank needs to be repaired or replaced as soon as possible to restore full hydraulic function and ensure safety.

Cool story bro!

Are you near Kashmir?

best get on and fix it then ... you guys don't seem to have any regard for safety issues, from what I've seen on Youtube - 'crack' on
