You're doing a clean job on this repower!  You will be fine on your 45 flare with these pressures.  The fittings will match the angle when you clamp them tight anyway.

 Double flaring is not recomended for hydraulic tubing. Especially if it has the backer sleeve , that acts as your "double"

 The rolled edge in a double flare used with 37 degree hydraulic fittings can and will crack the rolled edge . Also they put the preassure sealing point in a narrower band making it easier to develop a leak.

 

 As long as these joints aren't subjected to loads stressing them you should be fine.

 Also the 45 degree flare will work just fine , just make sure you tighten them good , back off and retighten.

Thanks .. I have a erratic? 45 degree flare tool would it be fine just to do a regular fare and not use the Double flare thing ? If the School lathe was was not locked out and the (Health and safety person has ever used a lathe they would understand Why its a good idea Not to have a Ton of guards and crap set up IMO its much more dangerous as you don't have as much of a clear view of site) i would make my own ... 37 degree tool ... the only reason i double flared them is because a while back i bought a Whole bunch of Used hydraulic stuff (from Gt's) and almost Every line was double flared .. and it used the Lighter tubing (brake line) like i am using Also the lines on this were double flared Worse comes to worse i will take all the lines to a Friend at a Hydraulic shop and have lines made ... Or buy a flaring tool But i will keep that in my mind about the Pressure point contact thing ...

Absolutely fine doing a single flare. With the backer sleeve your not supossed to double them. The pressures are low so that isn't a worry, Its the vibrations that usually wreck them.

Got the seat mount made its 2 way so you can flip the seat around (Backhoe..) Rebuilt the seat and recovered it Looks pretty good but the fuel pump and started it ... And in 5-10 minutes the temp went to 180-200F And the rad will still cold .... took the to hose off and it just dripped at 1/2 throttle ... pulled the water pump and it was Nasty should have it figured out tomorrow ...

on the front gear cover near the throttle linkage there is a tin cap covering a nut. remove the tin cap and the outer nut. loosen the jam nut and turn out the screw with a screwdriver a little at a time. She will smoke! You'll see what im talking about when you look at it
