Thanks for the post, I was having trouble figuring out all the bolts and you made it clear

[@MikeT]

Glad it helped

Thanks for posting. Ive just dragged out my 80 ironhead Havent started it in over a year. Gonna check the trans now.

[@cryptkeeper1340]

What oil did you use for the primary case?

[@romandybala]

Mike , what the hell was all that long hairy stuff on the drainplug magnet?

[@travistytoday4031]

Same as oil tank 80w?

[@USSHammerology]

That's a Valvoline max life atf dextrin mercon bottle.

[@DUMBERTHANYOUTHINK]

@@travistytoday4031 80? Do you mean 50?

[@jezwatson8211]

I’ve just got my first Harley a late 84 xlh1000, does this drain the gearbox as well as the primary? If so I’m assuming that filling also transfers through to the gearbox somehow? Thanks, Jez

[@USSHammerology]

Was that 50w Valvoline gear oil?

[@onewayrecordsTV]

I’ve got an 83 iron sportster, what fluid and viscosity are you using on your sporty?

[@pastorbobncc365]

That's what I want to know I have a 1974? Manuel doesn't say?

[@edgarserna5042]

82. I think 20w 50 is generally what everyone uses all around

[@pastorbobncc365]

What weight of oil did you put in the primary?

[@stevepershing4068]

What is that other large plug to the right of the gear oil fill plug?

[@HarleyRog]

Probably the clutch adjustment access

[@chrisrestifo7010]

For clutch adjustment

[@chrishartley8916]

You're supposed to us the side of a 1/2 inch wrench for those plugs to keep from messing up the plug.

[@kwik440]

is the 24 ounces for the transmission, and primary case ?
or is transmission gear box separate? My sporty is a 1973, thank s !

[@Chevyv8man1]

trany and primary oil is the same fluid

[@perryhallock5764]

[@weezerti]

[@MikeT]

Thanks, I bought it when I was 13, restored it when I was in college and now it sits in my living room/ man cave

LMFAO okay so I just went to change the primary fluid on my newly aquired '79... no big ass nut head... I have a short threaded rod pressed inside a lil rubber tube, that is then pushed into the threads, and it's all tightened with a nut on the bottom to expand the rubber... fuck me!!! And jeez does this thing know how to foul a plug.. praying it's just a carb issue and not have to do top end.
