engine and drivetrain Grooved Vs Needle Pilot Bearing

[eurotrash]

Ok, so I have an interesting question.  I am building a motor.  My '75 crank had a toasted thrust location and I had to use another, of unknown vintage.  I have a new sleeve and needle bearing set.  The new crank has the grooved ball bearing type pilot.  Here in lies the question..

 

item 18-19 show the sleeve and needle:

.. the crank has the 32mm I.D.needed for the sleeve, that accepts the needle bearing set.  

 

I was under the assumption that the sleeve exists to adapt the crank to accept the needle bearing..

 

Is this accurate?

 

this leads to the question, does the needle type take a cover?  I can't tell from any of the diagrams.

 

anyone have pics?

 

Thanks, m'friends.

Use the later ball bearing type... They still use that style today! There were longevity problems with the needle bearing style. There was a very good reason they updated them.

Ok. This is a grey area for me. Thought it was the other way around. :/ thanks Tom.

Hey Tom, do the sealed ball bearing type require the cover?  I can't tell.. seems protective at installation, but maybe I'm over thinking, as usual.

Correct, if you have the sealed bearing type you don't need the covers. Though, id they're there I usually leave em' in place with the new bearing; who knows if the next pilot will be a non sealed type. Hate having to tell the customer they need parts the last guy left out....

I had to replace mine last Fall when I had to rebuild my cylinder head. 

Make sure you save the sleeve. I had machine shop to press out old needle bearing and press new one into the sleeve and then I pressed the assembly with hamer and brass punch into crank.
