Upper Pinion Bearing (needle bearing) 40hp rude

[Intermediate Mariner]

Good Morning!

It's been a while since I've been around here... been actually working on the unit!

I am working on the lower unit of a '62 Lark 40hp evinrude but I have seen alot of other motors with this configuration (upper and lower pinion bearings).

The needle bearings of the upper are frozen. I have been using penetrant and various other liquids and am stating to get 'em moving but theyu got a long way to go to spin freely.

You will notice from my clips that the pinion gear got pretty ate up from this.

I have seen guys some say to leave it.

The big lower bearing is fine. Does the smaller upper bearing play a major role? It's doesn't really spin all that great new so I am wondering what the heck the point is... but it's a $13 bearing so I could go ahead (but it's pressed in uggg).

Does anyone know a trick to get it freed up?

Can I use a puller to remove? How would I go about this?

Can I use a brass punch to install a new one?

Any feedback greatly appreciated. Thanks!

I gave up on trying to free the needles. It also appears that while they were frozen they got grounded down flat!

I ordered a new one.

Anyone know any tricks to replace instead of having pressed in??

Thanks

Does anyone know any tricks to replace the upper pinion bearing? Is having them pressed in at a machine shop the ONLY option??
