Replacing 600A,2400vac Oil filled Circ. Bkrs.

Replacing 600A,2400vac Oil filled Circ. Bkrs.

Replacing 600A,2400vac Oil filled Circ. Bkrs.

(OP)
I am looking for Justification to replace 4 1964 West. Oil filled CB's.  They were refurbished in '93, but every so often refuse to start.  I am worried about spare parts, and although the oil has been replaced, about leaks.  I assume the 93 oil is flame resistant.  These are outdoor units all free standing with top mounted bushings. What safety reasons can I justify if any, and is it justifiable to spend $44K to replace the 4 with Vaccuum CB/s and a Main?

RE: Replacing 600A,2400vac Oil filled Circ. Bkrs.

It appears that more information is needed; especially, what is connected downstream, and the safety (or economical) impact of the Westinghouse oil CBs malfunctioning.  Probably, oil leaks might be fixed inexpensively as part of their routine maintenance.
