Default Engine oil in the primary case?

Ok, my search function seems to be broke so I can't actually do the work to see who else had this issue.

Long intro short:

Replaced connecting rods my self,
bikes back together now,
runs "good" but little issues.

Happy to say I've put 750 miles on it already.

The little issues include some small leaks. Some I can't see, some from the chain and some around the Primary Cover gasket. I've had some clutch slipping issues also so this prompted me to investigate the primary side first. Found that the primary chain was quite loose (@ 1.25" play). Also, the fluid was almost black, like engine oil. So immediately I assume I have some leakage from the engine to the primary. I drained the primary and it looked like some gear oil floating on or with some evil swirls of black thicker fluid (oil?). But I don't want to start totally tearing it apart if I'm wrong. Once I had it completely drained, I removed the clamp on the oil hose and didn't have the oil drainage through the primary hole that I expected to get.

So, I guess my couple of starter questions would be this:

1. How should the primary fluid and Engine oil look after 750 miles? Mostly all 55mph+. (75W-90 synthetic gear lube & 20W-50 motor oil)

2. What symptoms would I look for or see if I was leaking between the two?

3. (Ok, this one may be stupid) Can I check to see if it is leaking by running the engine without primary / clutch fluid in it with the plug out, if I'm not changing gears?

4. And finally (really, really stupid), am I really wrecking anything If I keep running it and just keep an eye on the levels? I know, a lot of hate mail coming at me for this one, but hey, I parked it for a year because of a little knock. I just wanna ride man!

Thanks for the help guys, you've gotten me this far.

I am not sure about the 1984 but I really don't think you should be running 75W/90 in the tranny at all, seems a little heavy to me.

Straight 60 wt. but I'm not as good with newer iron. I think 75w90 gear oil is close to 60wt engine oil cause they are rated different. Consult owners manual or FSM. Ther is a transfer valve in older Ironheads, not sure about 84,...

I use the same oil that I use in the motor (but then mine are the older versions) Harley makes a trans lube that I think is used in the newer sportsters.

Since you replaced the rod bearings you had the cases separated if you didn't get a good proper seal on the case halves you could easily transfer fluid between the engine and the trans.

Here is the Primary half:


Now, when I said I replaced the connecting rods, I replaced the connecting rods (with bearings and shaft that came with them). And a gasket kit. That is it. Everything else was left intact or just re-assembled. Right or wrong, it is what I could afford to do at this time.

Haynes S&R manual says for 84-85 Transmission oil - HD Front Chaincase Lubricant (part no. 99887-84)

Well, I don't want to believe it but EVERYWHERE I check for the 99887-84 equivalent it comes back with 20W-50...... Dammit, that's what I thought the problem was! Now I gotta fill the damn thing with it? Well like you said, maybe the 75W-90 was the issue.

How about the look of the fluid? Should it be this black so soon?

Finally being able to search a little, I'm sure I'm past the 100 - 200 - 500 mile break in oil changes. Though I'm not as concerned with following the true break in procedure since I didn't do an honest re build.

While you're there check the sprocket nut torque, the knock you heard could easily be that loose primary chain.

Yeah, that was all definitely all connecting rod knock. I've had it out quite a bit since I replaced it and the knock is completely gone. The only "noise" I have now is what I could describe as a scratching sound. Don't know if it is gear, piston ring or primary chain noise. Seeing how loose the primary chain was I'm hoping that was it. But haven't had it out for the last week because of the "leak" that I noticed. Really trying to take the high road and stop riding it when I notice something out of the ordinary.

just to be sure I'd refill oils, level bike and pull primary level plug, fill till it just starts to dribble out, put the plug in and ride for a while, let cool completely, pull level plug out again, if lots of oil comes out it's leaking in there, my first suspect would be the sprocket shaft seal.
