where in the hell does this go?

[XLFREAK]

ok so i may sound stupid....
i have a 1962 XLCH , does the tranny share oil with the engine or is it seperate.. if so where do i put the transmission oil in the tranny case?

[willprevale]

yup it shares the oil.

[74FeHeadXLH]

Yes tranny shares with primary. Recommended oil is H.D. Power Blend Super Pemium Oil. Stand bike level, tires touching ground. Remove oil filler plug on primary case (large slotted plug at higher level than clutch plug). Then remove the oil level plugfrom the bottom of the cover, should be underneath your footpeg a little forward, Then w/ pan underneath, remove the drain plug at the bottom of the crankcase which is underneath the clutch/tranny on the primary side of the case. Allow oil to drain for 10 minutes or so, don't forget to clean the drainplug, it's magnetic, and reinstall the drainplug. Refill through large fill hole w/ recommended oil until oil begins to come out of the level hole, bike being level, allow oil to stop seeping out of level hole and reinstall level plug, and oil fill plug, then yer done. Manual says 1.5 pints but it may not take exactly that much

I don't know much about '62 models, but he asked about tranny and engine not tranny and primary. Just want to clarification on this.

you got me there for not noticing the exact question, and you make good point. No the tranny does not share oil with the engine, but the tranny does share oil with the primary, and they require two different grade oils...tranny/primary moco reccomends HD Power Blend Super Premium Oil....and engine ('62) requires @ below +40 F HD grade 58 (all I can ever find is 60),and @ + 40 F and up HD grade 75 (all I can ever find is 70)

74FeHeadXLH, the old Harley grades do not equate to the SAE scale. Harley 58 is not equal to SAE 60 and Harley 75 is not near as heavy as SAE 70. The Harley 75 is near to SAE 50w and Harley 105 is SAE 60w. The MoCo used their own system so owners would buy their oil. After the old grade system they went to a system where:
HD med. heavy=40w
HD regular heavy=50w
Hd extra heavy=60w
And finally they went to the current SAE system (40w, 50w, 60w, 20w-50 )
Now, if your engine is badly worn it may need the heavier oils.

in 62 if i am not mistaken the 900 had a dry clutch----the the tranny oil goes in up at the mount for the oil tank but the 62 is not my passion

[flathead45]

double check to see if ya got oil in the primary after filling the trans, a popular mod was to weld up the transfer hole between the trans and primary and you may have one like that and not even notice till its to late

[Mountain Cop]

Sorry for bringing such an old thread back from the dead; I was furthering my edumacation by going from the oldest thread forward...

But why was it a popular mod back in the day to weld up the port from the tranny to the primary? What purpose did this serve? Was it so that you could use different grades of oil?

[Campsurf]

Was it so that you could use different grades of oil?

Yes... you could run a good grade of oil say 20-50 in the tranny... and then run ATF or a lighter oil in the primary.. as it is now I run 20w-50 GTX in the primary/tranny, same oil I run in my engine. The 1971 and later model with a wet clutch system sometime have problems running oil this way depending on the weather temps.

There is a lot of experimenting still going on. The new HD Power Blend seems to be the direction a lot of guys are going.
