Crack in cast

farmguy · Jul 7, 2008

I have a 1855 Oliver that has a crack in the housing that is the reservior for the hydraulic fluid. There is no pressure and I want a cheap/fast fix as this tractor is used on the haybine all summer. Fluid drips out if the tractor is running or not. Thanks

If you can clean all the oil off of it and shine it up a bit, I would try J.B. Weld.

I agree with the JB weld but I would suggest that after mixing it do a final wipe with a cloth soaking wet with a solvent like prep or acetone. That will get that little bit of oil that is going to continue coming out even if you drop your oil. Good Luck

You can try it, but JB weld isn't exactly a hydraulic pressure holder.

(quoted from post at 13:38:25 07/07/08) You can try it, but JB weld isn't exactly a hydraulic pressure holder.

Hydraulic reserviors typically are not under pressure so that shouldn't be a problem in the slightest.

I would try it, only out a couple bucks if it doesn't work. Big thing would be to get the surface clean and keeping it clean until the stuff sets up.

Drain it down below the crack.
Use an angle grinder to clean and roughen the cracked surface (not V it out) about 1 inch wide. Use JB weld in a 1/16" layer on the width. Lay fiber glass mat (one layer) over that, and work it into the JB weld. Put on a second coat of JB, and work the voids and bubbles out of it. Smooth the outside by placing a poly bag over the patch, and smooth to your satisfaction. Let it cure as the can says. Good luck. JimN

This will work. Don't know where Jim learned this but I used the same method on a Char Lyn resevoir. Did I tell you about it Jim?
Same method for poly tanks on 4 wheelers, using "All-Seal" instead of JB.

drill a small hole 1/16 at each end of the crack, this will keep it from cracking farther. you can heat it up with a torch to burn the oil out of the crack. i have aslo use the pinning method drill a bunch of small holes, put small brass plugs in and peen over.
