Does anyone know what the AN sizes (or even if they are AN) for the fittings on the frame? I know the one that comes out at the bottom of the front tube is smaller than the one on the bottom of the backbone. I also know AN-4 is too small and AN-8 is to big. Kinda wanting to get rid of the 30 year old hoses for something new/better.
Thanks.

You mean the threads for the oil hoses?
Are metric, I can check it out tonite...

Yes, the threads for the hoses. I did some more research after posting the OP and figured out that they were metric. The hard part will be finding adapters or fitting here in the U.S. that are metric. I didn't know if AN sizes were used just here or world wide. I wish the U.S. would have dropped our archaic measuring system back in the '70's and get on the same page as the rest of the world. I think the problem is that it is so entrenched here, it would cost to much to change. If it should come down to it, I'll have to cut off the metric fittings and braze back on AN fittings. NOT something I care to do.

Do you want to build some special hoses or would stock parts in good condition be o.k?

I was wanting to go with stainless braided lines. I all ready have them for my oil cooler but, my lower line is still stock. The stainless lines I have don't use normal AN fittings but clamps with covers to look like AN fittings. I was thinking of getting a Earls oil cooler and converting everything to AN fittings since this is what the Earls cooler uses.

Hello Solo2racr check this site (www.hertmotorcycles.com) has SS hoses, he calls himself Hank's engineering and luckily for me he's in my town (Cairns, Nth Queensland, Australia)
What he doesn't know about XT/SR's could be written on the head of a pin
for all I know he may even source his hose kits in the USA
hope this helps

That would be exactly what I need. Pricey though. I plumbed my old race car (4 brake and 4 oil lines) for what he wants for those two lines. It looks like what he did was the same thing I mentioned above and weld fittings on the stock aluminum end (top piece) and steel piece (strainer).

You could always make/have made an adaptor made for each position to suit the AN stuff...metric to imperial. You can already buy adaptors for the top of the cases and the oil tank return...but I think they may be metric...they are Japanese...I bought a set from Vanem to save mucking around. Haven't even checked the type of thread on them as yet. The blue-anodised return adaptor for the cases is seen below on the mockup engine...you could make it any thread you could imagine...well, more or less...heh, heh...the top one and it would be the same for the bottom of the tank, are female to male adaptors...

Thread size at backbone is M16x1.5
i.e 16mm outer diameter, 1.5mm pitch.

That would probably make the one on the strainer 14mm. I know it is a smaller diameter. Probably that same pitch too (1.5mm).

Here are some other ideas...not as neat perhaps as screw in fittings...   SR  |

The SR500 oil connection fittings are based on the (JIS) Japanese Industrial Standard (Here in the States. May be called something different elsewhere). They use a 30 degree fitting face. By comparison the AN standard uses a 45 degree face and the old (JIC) fittings (Joint Industrial council?) uses a 37 degree face. I have not had time to locate a specification, I'll see if I can come up with something this weekend.

AN is 37 degrees, not 45.
45 degree fittings are automotive standard

Aero - I stand corrected, AN is indeed 37 degrees and 45 degree flares belong to SAE. PC I have located some additional data which has left me more confused. It is improbable that the fittings are JIS based on thread pitch. JIS uses British threads (go figure) That would seem to leave Komatsu style fittings, but who knows could be others unrelated to the nation of origin. Here is a link that may help to sort it. www.gates.com/brochure.cfm?brochure=962&location_id=3584 |
