With a Standard seal this can be done with the TR2/earlyTR3 flywheel, but not 
the later flywheel where weight was added to the block side.  It is possible 
with most of my racing flywheels.
 
If you must do this (is the oil pressure and temp OK)? Start with the center 
cap and see how that bearing is.  Leave the other caps fully torqued, as you 
will probably want to rotate the crank, and the timing chain tensioner and 
front seal are at risk.  The gasket between the block and the front plate 
usually 
tears where it touches the front cap and sealing block.  The rear cap will 
need to be resealed.  If you run a good oil like Redline, the mains can be less 
than perfect if the rest of the motor is top notch.
 
If you do not have a lift or pit (I suspect like most of us) your quality 
control might be difficult.
When you work lying on your back, a red light makes it look more professional

Eye protection is essential, and a hotel disposable shower cap works well.

I need to change the main bearings in my TR4.  The engine is in the 
car with the gearbox attached.  Is it possible to pull the rear main 
cap?  I'm specifically concerned about the seal - I have the new 
split-type seal.  I took lots of pix of the engine as I assembled it 
*except* the split seal and associated bits.

TIA
