52c 1986 Copper Steering Lines

[rustybucket]

Hello all, I'm wanting to replace all the copper steering lines below the cockpit. They are showing their age and I just don't trust them 100%. I meant to get the sizes when I was down last weekend but I just forgot.

Anyone happen to know what diameter the copper lines are? My brain tells me they looked like 3/8" but I could very well be wrong on that. Also, I believe there were 3 lines, anyone know if that is correct?

Also, I'm assuming the fittings are all flare fittings and no soldering will be involved? If soldering is necessary I'm good with that, will have a torch with me.

I would just go look, but the boat is 4.5hrs away and I'm hoping to purchase the copper this week so I am able to do the project next saturday.

Thanks in advance for any guidance you guys may be able to provide!

It should be 1/2 copper refrigeration line. Some have the return line as 3/8. All should be 45 degree flare or hydraulic flare (37 degrees) depending on the parts it attaches to. Make sure you get the refrigeration grade copper. Also the last few feet should be hose. Use the MHS6 from parker with appropriate fittings.

Its a PITA to get to some areas so keep in mind the old can help pull in the new.

Thanks, all my hoses are good and have been recently replaced, only the copper is looking sad. Thanks for the info!

Use a good flare tool and be very meticulous with the flares. Particles and debris will screw up the helm if they get into the valves.

By 'good' I'm guessing you mean, "not the harbor freight unit i was going to buy tonight?"

Any suggestions on a good flare tool without breaking the bank?

Spend the time to go to a place that has quality tools.

I recently replace some copper lines on my 46C, 3/8 inch and the flares are 37 degrees, when purchasing the copper, I found cheep stuff $30 dollars for fifty foot roll, and 125 dollar for 50ft roll. the cheap stuff has very thin wall thickness and is used more for small aircons. I purchased the thicker walled line (obviously) Flaring is easy, use the correct tube cutting tool and clean up the cut end before flaring. also cut the tubing a bit long, in case you don't like your flare, a little excess can be taken up with a little extra bending along the length of the tube. Have fun, I did

Mine have been replaced with flexible hydraulic hoses. So much easier to maneuver and get into those tight spots with something playable. Good look either will work.
