Breather Hose

Description: How do you all run the hose so it doesn't make a mess?

'58 Pan, 1 1/2" belt drive primary. How do you all run the hose so it doesn't make a mess? Any clever ideas?

[sleeper]

I have run it back out of the primary area & aimed it down at the ground & added a little Breather screen
filter. Out of sight. & away from the Belt..

I run open primary So it will differ slightly, 1st shut off the oiler screw (small screw on oil pump, runs on 45 deg off pump to ground) shut off ever so slightly or it will ruin the seat. Cut the breather tube to run down to ground. Hook up hose to direct the drip, it will still drip even shut off, this is where you can easily ruin the seat trying it to shut off completely, it WON'T. Panheads mark their Spot. I cut at the 90 deg bend and run straight to the ground. With an inner try to get the hose out of the primary. Good Luck

be sure you use large enough hose , the first one of these i made was a cap on the breather i machined from a peice of aluminum, D&T a pipe thread on it for a 1/4 hose ran it through a hole in iner primary to drive chain , condensation pluged the hose after awhile , crankcase could not breath , oil went squirtin all over the place!! went to a 1/2 had no probls with it .. shaker.

I stuck a "green" garden hose on mine back in 1980 and it quickly turned black and it stayed. Now I'm rebuilding and will put some good oil line or something on mine. It was 1/2" and about 6" long.

Weezo, I've got mine turned up on a 45 with the intention of putting a trap in it before running under the trans and then to the back of the bike. My idea was to keep whatever oil in the crank and venting the blowby,Yea, nay, or what do you think? Ed

[weezeo]

Sounds OK But Is it venting? Thats what its suppose to be about. I ain't sure on that But would want it to have the right amount of breathing going on down there. Wouldn't want something little like that to clog up the bottom and burn up a bushing or bearing. But it sounds like it works to me.

Don't put a "trap" in the breather hose. Yes, on a kitchen or lavatory sink. But trapped, the hose can't breathe freely.

I agree with V T, this isn't house plumbing. The oil in "your Trap" is already out of the crankcase, let it breathe Freely & mark it's spot. It has earned that right!!

Ok,Ok, I got the picture, No Trap !!! Thanks guys, Ed

There is a little screened breather that could be attached to the end of the Breather Hose and has a tin bottom that would let it breathe freely & collect the drips. Clean it out once in a long while. Costs about $13. bucks..It's like a tiny K&N filter. I've used it before & it works well. Think I found it in J&P Cycles catalog.

I put a 3" long piece 'o' hose on mine. The last time I had it off, I found a socket that wouuld slip inside and used it to push a screen up the hose a little ways. Still there, the last time I checked. I think it's important to keep the breather open, if somthing happens to the oil return, it'll let you know in a hurry. Mine leaves a quarter sized spot of oil on the garage floor when parked overnight.

Another reason for the open-hose is that a Big Twin motor not used for awhile, will sometimes "sump" and alot of oil will go to the bottom of the motor. When the motor is started about a quart of oil will empty out of the motor (a natural occurrence) and you don't want any restriction in the hose.

[sleeper]

Sumping is a problem easily solved by "burnishing the check ball seats. Not something you have to live with!!

[weezeo]

Yea when it does that "collect the oil on the bottom then Fart It Out" after sitting like VT said, You will wonder what the F*&%D happen when you see, what looks like your complete oil bag laying on the garage floor. That will freak ya out, which brings me to why I posted, I would'nt put no screen on the hose. I want everything going to the ground (talking bout belt drive, not chain) since it isn't being reclaimed No screen nessecary let all the crap roll all over the frame and tire etc... No since cloggin a screen and leaving it in the Bottom End, If it was there to lube a primary OK but i don't use anything to screen the breather.
