Stuck new oil pump

[atlanticave]

Hello guys,

I have just bought a brand new oil pump from the dealer for my 89 sportster 883, 4 speed.

Unfortunately it doesn't rotate. Seems stuck due to the old lube (the box says it's from 2000).

I started disassembling but I can't remove the inner plate, I wouldn't want to ruin it. Any advices?

I tried wd-40 and little knocks on the table.

Thank you so much!

More solvent and try to turn it. I think you are right, the packaging lube has it stuck. Because of the flat spring between the plates, these pumps can feel extremely stiff, even when correctly assembled.

Ta-da!

Just unlocked, let the wd-40 do its job!

Thank you jim, as always.

You are changing horses in the middle of the creek ...

There was a design change ... 77 to 90 was for the 4-speed Evo Sporties and when the 5-speed Sporties came on line in 91 the pump was changed ...

Not all that sure if 91-up pump will work on the 90 and back models ..
Might be best to do a bit of research ...

I think he means the pump was made (or packaged) in 2000, not that it was for a '00 year model. And yes, those are not bolt-on swaps.

You are right!

I found a brand new replacement as a closeout from a HD dealer made in the year 2000.
