Packard Forum Index » Post-War (1946-54)

Can someone please pull up the specifications for the main and rod journals on a 359. Just got a call from a friend of mine with new bearings and new machine work on his crank - trial fit is at least .015 loose. link to specs on the site appreciated - I am typing this as he is crying to me on the phone...thanks!

David - My 1958 Motors Auto Repair Manual shows the following for all the 1954 engines:

Main Bearings: Shaft Diameter 2.746-2.747" Bearing Clearance .005-.003"

Rod Bearings: Shaft Diameter 2.249-2.250" Bearing Clearance .005-.003"

Rod End Play: .003-.011"

The spec table shows these same data for all engines back to 1952.

I hope this helps.

JW, I didn't check the specs but are you not missing a "zero" in the minimum specs? I think the min should be 1/2 thousandths or 0.0005".

Packard main bearing specs same as JW's Motor Manual -- 2.7465. Clearance is as O_D mentions -- .0005-.0025

Yep, four places to the right instead of three. My typo mistake. Good catch.
