A few questions. Oil pressure is about 20-25 psi with 50w on start up. Is this good?

I was watching the return line in the oil tank to make sure I'm getting return, and it's not a steady stream. More like spurts every second or two. Is this expected?

I noticed that the primary chain is not getting oiled. I messed with the adjuster screw, and still couldn't get it to oil. I even pulled the screw completely, and noticed the screw was completely dry. Isn't the primary chain oiler on the same 'circuit' as the cam gear galley? How do I know if the cams are getting oil? I'm returning oil fine, and the gauge shows 20 pounds. The cams do sound noisy, but I guess I expected that. I just don't want to do any damage. Should I pull the oil pump and check the springs and balls?

Just concerned.........:confused:

All your going to get is a little intermittent burble on the return. What your seeing is completely normal. I'm not sure about the PSI rate... a more knowledgeable member should be able to tell you.

As for your primary chain.......did you have small washers under the screw? If not and the screw was turned completely down then the oiling would be shut off. I had the same problem with mine and found the rear chain was getting too much oil and swapped washers from the rear chain oiler to the front chain oiler (the more washers the more oil you get to the chain). I got a little bit more but not much. I just ended up checking the chain periodically and manually oiling it. The manual says to periodically pull the screws out and flush the passage with gasoline and blow out with compressed air. I've not done this yet. Maybe there's an up-to-date fix on this?

Your definitely going to hear some noises coming out of the ol' flattie. Don't get too worried about it unless the noises are real bad!

I'm actually glad you posted this as I'd like to hear feedback as well from the mechanical wizards on this forum! :D

I actually removed the screw COMPLETELY! The screw was dry and still no oil was getting to the chain. I'm just wondering if that 'circuit' is blocked off, and no oil is getting to the cam chest.

Did you insure that no passageways were blocked after applying the oil pump gasket?

This just came to me....... what year of 45 are we discussing?

Sorry..........The motor is a 1954 G........the rest is a 1935 RL.

No I didn't. Maybe the pump gasket is blocking that passage?:confused:

The '35 in your handle had me wondering.....:D

Could be...... I'd be thinking I might check it. Hopefully someone else on this forum can provide some input.

Hopefully........

Pulled the pump off tonight. Checked the spring lengths, the balls, reset the screw to 3/8" below body. The gasket looks fine. The holes are all there. Squirted carb cleaner through the chain oiler screw adjusting hole.......it shot out through the cam cover. That's good, at least I know I've got a clear passage from the pump to the adjusting screw. Put everything back together, started it up......nothing again. Put a coat hanger through the oiler tube on the primary side.......something is stuck in there. Tried 'hooking' it out. Ended up pushing it into the motor! :( Got a piece stuck on the coat hanger........PAPER TOWEL. Stupid me. That's what I get for taking years to rebuild this thing. Forget what you've done. Probably stuffed some in there to bead blast, the pressure forced it down the tube, couldn't see it, then forgot all about it.

So..............

I forget what the inside of the cases look like. Where does the oiler tube go inside the cases? What if I did push the paper towel in the cases? Is it just in the flywheel area, or did I shove it inside the cam cover? Even if I took the cam cover off, could I get out the rest of the paper towel, or would I need to split the cases? I don't think that much damage could be done if it's just in the flywheel area, and I'd expect it to fall apart pretty quickly.

As far as the oiler adjusting screw being dry......maybe I need to run it faster than idle to get enough pressure to activate the bypass circuit. :confused:

All in all, this sucks, and next time, I'll need to be more careful and check all passages with compressed air to clear them before putting things together.

I bet that it won't hurt it, it is soft. It will undoubtedly disintegrate wherever it goes into some oily wood pulp. Those motors are pretty hardy. As for that oiler, I know that you should see it drip even at low rpm. Denise

I agree with Denise, except for a concern with blasting media, which may have built up on the paper towel.

Okay.......

After looking at a set of cases, I found out the oiler passage goes through both cases and into the cam cover, and NOT into the flywheel area of the motor. Bought a long 3/16" drill, and worked it by hand through the oiler tube, snagged the paper towel, and pulled it out. Blew through the oiler adjusting screw hole to clear any left over debris OUT of the engine. Now that is clear. And last night I made sure the passage from the camcover to the adjusting screw was clear by shooting some carb cleaner through there. All passages are clear.

Started it up..............STILL NO OIL. WTF is going on? :confused:

Maybe I'm just suffering from a brain freeze but you've got me stumped. I've dug through all my books regarding 45's and their oil pumps and have not come up with any reason why that would happen. Could one possibly fire it up and add oil to prime it? Just a thought. Surely someone can speak up on this matter........

You should prime it anyway.

Prime the chain oiler?

The bike was started with about a pint of oil poured over the rod bearings, and cams.

The oil tank was filled, and the line pulled off until oil flowed to the end of the line. Then the line was attached.

Maybe I'm just not getting enough pressure to open up the bypass circuit which oils the cam chest and the primary chain? I dunno, I'm at a loss.:rolleyes:

The bigger problem I've got at the moment is the old lady across the alley who came out today in her robe screaming at me to 'turn that damn thing off! You've ran that thing 3 days in a row!' When she started getting rude, I told her 'I've been working on this thing for 10 years now, you're gonna have to deal with 3 days!' More expletives were exhanged....

I hate yelling at an old lady. But when you approach someone screaming and yelling, expect to get it back!

Just wait until I get this thing rolling.....head to work about 6:30am, I'll light it up and warm it up fully every morning. No respect I tell ya! :rolleyes:

You should have mentioned to the old girl that it could be worse in the neighborhood. You could be one of those young punks with one of those unbelieveably loud stereos that pump the bass so hard one's ears could bleed! I've got a neighbor like that and it took me to completely lose my temper with him before he got the hint to turn the racket down!

O.K. back to your chain oiler......... do you have a copy of the military green manual? It paints a little better picture of the oiling system. If you don't I will scan that section and post it for you. I have a theory now but since I'm not 100% confident of it I'd rather let the folks who wrote the manual give you the info. I'm actually really surprised that there hasn't been more input on this.

Oddly enough, she is the landlord of the building across the alley. I've been kept awake at 3:00am from some of her very drunk tennants talking loudly in the alley, playing loud music in their cars, and a few fights. I think she's just pissed because another guy on the block flys through the alley at about 50 with his brand new harley with drag pipes.

Anyways, I do have the green army manual. What is your theory? And what page are you looking at?

Damn neighbors.....:mad:

O.K. my theory comes from the Motorcycle Mechanics Handbook from 1943 pgs 31-34 (It's green and comes from the Motorcycle Department Fort Knox, Kentucky). If we are assuming that the chain oiler works off of the same circuit as the gear case (cam chest) then you wouldn't see oil to the chain oiler until after your rpms are up and the oil pressure reached 30-35 lbs. I'm thinkin' you might need to take it for a ride........:D

But like I said it's merely a thought in my head....... I'd hate to have you rely on my ramblings....

I meant prime the pump. Didn't realize pump was working when I made the suggestion.
