TD06 Oil Feed Options

[Ceddy]

I'm running HRC Super 16G, which is a Small 16G compressor and TD05H turbine in a TD06 CHRA.

The TD06 CHRAs use a M12x1.5 banjo for the oil feed, instead of the M12x1.25 used in the TD05s.

I've had nothing but bad luck with the M12x1.5 banjo bolt.

At first I couldn't find one anywhere, so I had a Machine Shop make me one out of a M12x1.5 bolt. It worked O.K., but oil would creep up the threads since the bolt was threaded the whole way, and leak a little. Then when I was tightening the banjo, it broke because the shop made the sideways holes a little too big. Removing the piece of bolt that was left in the CHRA involved me removing the whole turbo that I had just installed two days earlier.

I went to the Mitsu Dealership to get one, they charged me $22 for one banjo bolt, and when I got it home, it was the wrong thread pitch.

Then I found SlowBoy had a banjo for their 20Gs, its a XRP #494815, M12x1.5.
The only problem with it is the head of the bolt is smaller then the crush washer. So it bends the top crush washer concave and leaks a little. It doesn't leak much, just a drop or two, but I'm afraid it will squirt oil at high pressures(high rpms).

Does anyone know where I can find a OEM style M12x1.5 banjo bolt? I know the Syclone/Typhoons used them with their 17C turbos and some of the Fuso trucks also have the TD06 CHRA, I just can't find anywhere to order them.

Also what are you guys with TD06 CHRAs (20Gs, Greens & Reds, Franks, etc.) using for your oil feeds?

Thanks.

WHy not just find a copper washer that fits, at you local hardware store?

I have the proper size crush washer, the XRP bolts head is small compared to the banjo fittings hole. The bolt head and banjo fitting don't overlap enough, which causes the washer to bend.

I've got the one from slowboy that's specifically for the TD06H 20G, and it doesn't leak at all. You may want to try thicker crush washers to solve your problem.

In the past I made my own bolts. Just make the hole smaller and you won't have the breakage problem at the measly ~22 ftlbs they see. A drill press makes this a breeze, but I've gone comando with a hand drill as well.

+1

or try using 2 washers under the bolt head
