'67 Chrysler 55hp Model 5561 Upper Thrust Bearing?

[chirombo]

My motor has a damaged upper bearing where the races have dropped out, that I am unable to remove. I'd imagine it should be a press fit, but my early 50hp manual and the later mid 70s 55hp aren't specific. My eyes aren't what they were, but it looks like it has a thread? Is this the case?

If you mean the upper ball bearing it is press fit to the crank.

No threads anywhere on the crank.
​Except the top where the flywheel nut goes.

​That bearing on the top is a press fit.
​With a bearing separator and a press and an acetylene torch it will come loose.

​The picture shows red circles?? that bearing has locator holes that need to line up with dowel pins in the block.
​There might??? be 2 there?? can't see under the crank.
These HAVE to be fit in or the crank won't turn free.

Thanks both, I put it through a commercial press and separator this morning and it popped out. Apologies, was a red herring, but the red circles were there before. This motor blew it's gasket last weekend, but for years before the crank must have been at a slant to put such wear marks in both top and bottom bearings. It's recoverable and I like this motor, for it's overall lightness and willingness to work hard, so your help much appreciated to get it back on the water.
