Oil line rebuilding?

I'm new to AN fittings, so am not familiar with the Summet/Earl's fittings.

However, here's what I derived from your posts: If the sleeve doesn't show signs of crimping, then it's internally threaded RH M20x1. Also the barb inside the hose appears to be threaded. If there are signs of crimping on the sleeve, then it has to be cut off & a new sleeve installed.

Your bottom hose assembly had threaded fittings on both ends, & the top hose was crimped on both ends.

BTW, It looks like the line routing would be cleaner if the oil filter input were connected directly to the motor, then the filtered oil run thru the oil cooler.

Can you think of any problems in doing this other than making sure the cooler didn't have any sludge or foreign material inside it?

 

Jeez, when the one on my Mondial bit the dust I just called Ricambi and bought a new one!

 

Stock coolers are aluminum. TIG on AN fittings and convert everything to AN. Future replacements are a snap and you can get a new hose made anywhere... hell, even them NASCAR boys can build ya an AN hose.

Resurrecting an older thread.

I am tiring of running around and trying to get shops to rebuild my oil hose. So, I am going to set this up myself. Never did an AN hose so here goes.

Can someone (Peter, or LuckyD) give me the part number of the 90 degree fitting posted above? Or the specs?

Does Summit Racing have a kit to make AN hoses?

Thanks

 

I don't have a manufacturer name for the elbow I used (the parts guy just walked over to the shelf, picked it out of the bin and brought it to the counter), but I believe it may be a Parker fitting. Or it could be Aeroquip. In any case, the P/N on the invoice is:

1JH9-12-22-OG

It's a 90 degree elbow, -12 JIC flare (so 37 degrees. I believe AN specs 45 degrees, so be careful when selecting your hose end fittings), to 22mm thread. I believe the "OG" is the style of the metric threaded connection.

 

I forgot to add to that post, I think this is for your 328 oil line? Just double check the metric thread on your car. The GT4 uses M22 x 1.5mm.

Here's a list from a Google search on that P/N and it displays all the sizes available for this type of fitting:

Peter, thanks for the info.

If anybody has this, I bet you do. What about the part number for a 90 degree elbow at the oil radiator? This will make it so that the oil line is a straight line.

 

I'd have that concern with a new filter, but a clean one that's been in service for almost 40 years is unlikely to have anything coming off inside.

yelcab,
The AN fittings aren't generic, each mfg designs the fitting's barbs, compression ferrule, etc. for a specific one of their line types. I reccommend getting Holly's EARL's & Eaton's Aeroquip catalogs, one of their line & connector systems. Fittings that do something like converting from an AN male to a metric thread should work with any mfg's fittings as they don't connect to a line.

Sean, I am constantly amazed at your prolific ingenuity.

I haven't the machining capability, so used off the shelf stuff.
Here is another shot of the adaptor that works well. Note how much shorter it is than the standard 90.

I was concerned about the flow restriction tendency of an old style banjo, so i used a formed 90 for the return, with an adaptor.

The 180 degree thermostat really helps the oil get up to temp in our chilly north coast.

Here's my 1st New Year's resolution - to measure my 308's hose lengths & get a set of extra's I have out to Canada by the 1st week of the year. I found a hydraulics shop that is suppose to have the identicle fittings (I sent pics) and will build the hoses with steel braided cable. THey want to actually see them. BTW: My QV has one length, Carbed cars have another, and I have a 3rd set still another length. (2) are steel braid, one is straight rubber. All three original. Gotta Love Luigi on the assembly line.

Stay tuned.

 

The oil cooler I have is an aftermarket B&M item and the fittings on that is just a normal 1/2" NPT thread. I used a common fitting to attach my hose to it. It's one of the reasons why I went this route was for the NPT threads on the cooler, so that I wouldn't have to deal with the goofy banjo and metric DIN stuff again!

Take Verell's advise though and look through those supplier's catalogs, I guarantee you'll find the right hose end or adaptor to fit your original cooler.

 

Are they in Montreal?

I had a hydraulics guy here in Vancouver build me a set of hoses and sourced out the banjos from a supplier in Montreal. That was okay, but my builder out here put the hoses together and not being familiar with these parts, over-crimped the sleeve and they started to leak within a year of being on the car. I mean he crushed the **** out of the nipple on the banjo. I hope your source will do a better job than what I got.

After that experience, I started to make my own hoses.

 

Thought I'd post an update.

I finally contacted the Company in Canada who supposedly makes the hydraulic lines for the oil cooler: alfagomma.
I sent up a set from another car & asked them to match them, but to the appropriate lengths for a QV. He tells me he carries the same fittings & it'll be shipped out Tues (closed Monday so 1 day turn-around wow.)
and for $50/ea Canadian + shippping.

I'll let you know how they look & work when they get back. I'm thinking a week shipping from Canada via UPS.
If they look good, I'll post up the specifics so others can order them.

 

Thank you. I'll look forward to reading your update, as I would sure like to replace mine before too long.

 

Due to a mix-up in sending addresses, my order was lost for a few weeks. My fault. Bad address. But they got it!
Now, as long as my measurements were right, we've got a solution!
And I have to say, they look great!
The top is the original I sent up as a guide off of a different model year bought on ebay. The lower two are replacements.
I did send up measurements off my '83.
Hopefully this Friday I'll see if they fit & we'll see how they work. As per the shop: "Hydraulic hoses aren't rocket science anymore".

thank effing God. $50 sure beats $350.

 

They look like beauties....looking forward to your fitting, as I want to buy some very soon. Did they file your specs away, for future incoming 308ers?

 

Looking at the picture above of the 3 hoses. The original hose has spin off ends. Just replace the hose with Aeroquip 12AN hose and 15min time. My '82 308 GTSi had 6" of hose - I purchased 36" on e-bay. 12AN hose for $26 delivered. The fittings spin on/off and expand the hose to fit, just wrap the hose in fiberglass packing tape and use any cutoff tool.....

 

It came to $140 US for both with shipping, tax, etc etc.

I fibbed a bit. I told them it was for a Fiat. But they do know the ends & build. But like all things Ferrari, I have three sets of those hoses and none of them match another. I suspect you'll have to either send up good measurements or the original hoses.

Of the 6 hoses I have, only 1 spins off. the others are either uni-construction or so darn frozen on, I can't get them off.

I think I posted I checked a couple pneumatic hose shops in my area. One very large. All were willing to hack the ends off & weld them to new hose, but nada on any guarantee. This turned out to be just a great deal all the way around. That is if they fit & work.

Stay tuned.

 

Finally got my car out of the shop.
The new lines from the Canadian outfit are in. A couple hundred miles on her and a bunch in this 95 degree heat. So far, so good.

All the hoses were replaced - braided with braided. The cross-over rubber was red - the only down-side. Me & some black Ink will take care of that soon

Do you have a link to the canadian company? I bought the "last" top rubber hose in the us this month.....
