Cota 348 Piston Size

Featured Replies

Could anyone out there please tell me what the following piston size`s are for the 348. Std Bore / 1st oversize and 2nd oversize.

Hi zulu,

I have a parts manual in the workshop which may have this info, failing that, I have a 348 motor in bits that I can measure up but will be later in the week.

Bye, PeterB.

Fantastic news - do you mind if i send you a pm?

Hi zulu,

that's fine,

The P/N's are 5160.074 for a std piston kit, over sizes are +0.25mm and +0.50mm. I just measured the bore - luckily it is in good condition, it is 78.25mm diameter, the piston crown has a marking of 0.25 so I imagine then that the piston is a first oversize, of 0.25mm and the std bore would therefore be 78.00mm.

Bye, PeterB.
