The Hydraulic shop will want to know what pressures and temperatures this hose will be subjected to. I suspect pressures will be less than 300 PSI and temperatures less than 250 degree's F but that is my guess. Maybe one of you have details?
If you don't know your pressures and temp needs they might sell you a hose that is over kill for your application as some hydraulic applications need to handle over 3,000 PSI. |

A standard hydraulic hose would be JIC 37 degrees so, do take the fitting with you to the hose shop for a match.. |

Yea, I got to replace the "90 fitting" as I messed up the threads. Are those special hoses are will a standard hydraulic hose work_I can have them made here in town?? |

Gee that looks just like my picture from the other day Probably the only thing that might be needed is a new hose since that fitting looks pretty rusty but with a little time and effort I figure it would work just fine.. |

Meet me down at the boat house but wear your long johns. It has warmed up and this morning it's up to - 5. Sorry Ken but I have never had a need to measure the flares on my B/W Velvets so I never realized they would hack and go with the cheap low pressure fittings. On second thought, it's who marinized the engine. |

You have a B/W, why don't you go find that fitting and unscrew the hose and measure the angle. It's the same fitting over at the cooler, you can remove it without losing any fluid that way |

We're all used to seeing a 90 degree fitting there Zach. The discussion is about the angle of the taper on the end of the fitting where the pen in the picture is pointing to. A 45 degree angle is commonly called an SAE fitting and a 37 (really 37.5) is a JIC or AN fitting.. The JIC is for high pressure hydraulics among other things. The SAE is for lower pressures. A B/W transmission is not exactly high pressure hydraulics in action The regulator in the transmission will keep pressure under 200 psi. Per the B/W installation manual cooler pressure is about 40 psi at 2000 rpm. That's going to the cooler not the higher pressure to the clutches Maybe with really cold fluid and about 6 thousand RPM you might see 250 ish to the clutches You could fill a book with info on fittings but generally with the JIC stuff they're made of stainless steel for the higher pressures involved along with better sealing ability due to the angle/amount of contact between the sealing surfaces. Generally is the key word since you can find either kind of fitting in a variety of different metals |

Tim, What hardware store carries JIC 37 degree fittings? A JIC 37 degree fitting is NOT special but, they are common to hydraulics. Where did the "notion" of 45 degree fittings used on hydraulics come from? |

I recall only ever seeing a 90 degree coming out of that port on Nautique installed BWs.

Pretty sure I’ve used hardware store JIC fittings on my transmission. Obviously you shouldn’t mix types... but I’m with Ken- where did the notion that a special 37deg was needed come from?

John,
Yes, as Ken mentions, do check and I suggest using the correct fitting. Mixing 37's and 45's is not sound practice and you could end up with a mess. I happened to find a trans Ken worked on where he mixed up the fittings back yard hacking. . I sure hope there's a couple quarts of ATF on board: |

And for another suggestion I'll suggest that you talk to SkiDim about whether you have a need for a JIC 37 degree fitting like Pete thinks or whether the original hose takes an SAE 45 degree fitting I measured the angle of what was in the transmission and shown in the picture from earlier today and it's a 45 degree angle. mated to an original PCM hose with an Aeroquip tag complete with the PCM part number.. But I'd verify this just to be sure. Now whether Pete thinks that's right or not, that's a completely different story. |

10-4 on the lowes stuff, I think I might have saved all mine, except will replace the hoses for sure.
And look what I found thanks to KENO suggesting I look in hole..... |

John,
I went to Lowes and my suspicion is correct.Don't even try to use it. Just because the threads fit, doesn't mean it's the correct fitting. Return it the next trip back to the store. The Lowes fitting is a 45 degree flare |

John, I highly doubt the Lowes fitting is correct. What you most likely got was a 45 degree flare fitting typically used on soft copper pipe for low pressure. JIC fittings or 37 degree and meant for high pressure. McMaster has them. |

Sorry wasn't trying to bypass y'all . I just couldn't find the name of that part, and I had talked to Vince before(Used to live right down the road). I didn't say I got the parts , I think it was they have them if needed. I went to Lowes and found what I think is the same brass fittings, will let you know after I go start working on it this afternoon. Thanks again, JT |

John, Check the hose end size. It's may not be a JIC-7 but rather a JIC-8. A - 7 will have an OD of 11.5mm (.44") and a - 8 OD will be 12.7mm (.5") |

By the way, it only seems fitting that if you're gonna ask for advice and then you call SkiDim or somewhere else, you should update the post with more than just saying you got parts
Something for the next guy to refer to would be nice |

Well that picture seems to tell me that the same guy that handled your wiring job akso dabbles in plumbing
Here are a couple of pictures showing what the screen and associated parts look like. We'll call it a typical setup since they changed some over the years, but this came from a mid 80's 10-17. You need the elbow fitting and depending on what the hoses you have are you may also need hoses to properly mate to the fitting. It's 3/8 male NPT on one end and 1/2 inch flare on the other. Like you said SkiDim has the parts They'll sell you some different fittings like part number 122611 and 122711 that will work or you can get their part number 122511 that works in place of the other 2 and is what Borg Warner used.. By the way, did you physically look in the hole to make sure the screen that slides over the tube isn't in there. They tend to stick in there and have to be pulled out or maybe like Duane said, somebody chucked it. |
