Pin hole in tractor oil cooler pipe?

[Dry Rot]

As in the title. How to fix? I am assuming oil in the oil cooler is at relatively low pressure, as compared with oil in the hydraulic system, so can I just clean it up and silver solder without a patch? Or even soft solder? I am experienced with silver soldering and have the kit. Tractor is a MF 390.

JB weld ?

Not much to lose with either. If you use solder, it should flow into the hole nicely. I'd stick with regular lead, 40/60 or whatever, better flow and wetting than silver solder. If you try JB, apply a little suction to pull it into the hole for some grip.

Low pressure, so not going to blow up on me! Just what I wanted to know! Thank you.

Braze it

Small screw? Resorted to this method on my digger when couldn't get it repaired cheaply.

Did you get the engine noise/vibration problem solved?

New clutch.

My torch does not get hot enough for brazing. I have done plenty of silver soldering. Soft solder would be easier if it would work as I don't have hard solder here. So either Ebay or a trip to town. (35 miles one way).

Cheaper than an engine.

Cheaper than an engine.

£1,000 off the shelf, I believe. Haven't seen the bill yet.
