I've seen several post speaking of Jaguar offering no oversized bearings...Has anyone on the forum considered utilizing babbitt?

 

You mean making your own oversize bearings from babbit (whitemetal)?

 

do you mean UNDERSIZED engine bearings?? to fit a reground crankshaft.

there has to be someone manufacturing bearings for a Jaguar engine!

a good bearing today a steel backed aluminum faced bearing surface.

babbit is soft and pounds out easily, dont seem like a good choice.

 

all I know is that it has been used for ages in engines....is currently used to this day in reciprocating situations...just an idea....Certainly there HAS to be SOMETHING not Jaguar specific that will work..

 

Racing Green sells oversized bearings.

Racing Green Jaguar - XK 1996-2006 - Engine and ancillaries

Look under the Engine and Ancillaries.

 

comon guys, 1st off, why do you need OVERSIZED ENGINE BEARINGS?

there are thousands of UNDERSIZED engine bearings for all kinds of engines!

now if you are the technician here, im sure i dont want you working on MY engine!!

also they actually do make some,but few, oversized bearings, but after 60yrs of engine restoration, any engine requiring them i would not apply any warrenty.

 

The crank bearings are ground down and the bearing shell replacements ARE OVERSIZED- If there is a lesson in pedantry- get it right: The OVERSIZED shell bearings are this way to fill up the clearance of the newly reground journal bearings of the crankshaft-be they mains or Rod bearings- quite simple really (and not originally availiable from Jaguar until Racing Green started offering them)

 

Thank you Kind Sir!

To quote the Racing Green site. Crankshaft bearing V8, mains 0.25mm oversize
Part No RG MBJ 0.25MM

 

You tell em Count...had to look up pedantry though

 

A case of shorthand becoming entrenched and creating confusion when taken literally.

HI, Cammerfe,, i will bet most guys here dont even know what a Ford FE CAMMER V8 is.

produced in very low numbers around 1967-68.

and like i said if they dont know what an undersized engine bearings is, they aint gonna work on my stuff.

lemme see if this can make sense, when you ruin a hardened crankshaft bearing journal, and reduce the journal diameter by grinding it smaller,it becomes undersized.

that is the USA standard of nomenclature for engine bearing use.

and (probably UK) may refer to it as a thicker bearing shell, could be 0.25mm or in American english it is a .010 undersized bearing shells(two per side).

and in actually measuring the one shell it is 0.12.5mm or .005 thousandths in. thicker,
the bearing has two sides remember!

and i know this dont mean a hill of beans, i taught college level vocational engines,Daytona, for 6yrs.

i hope some of this helps the misunderstandings here.
