October 29, 200817 yr Could anyone out there please tell me what the following piston size`s are for the 348. Std Bore / 1st oversize and 2nd oversize.
November 3, 200817 yr 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.
November 4, 200817 yr 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.
December 29, 200817 yr Hi Peter, would the piston be a tarabusi and do you know if all 348's had this make thanks Dave
December 30, 200817 yr I think the 348 used a mahle piston. http://solomontesa.com/tienda/product_info...2f48301ad2301ee S_M.
January 3, 200917 yr Thanks VC, i needed a set of rings for my 348 and just got a set from ebay (0.5 o/s tarabusi) USA. 78.5mm ,montesa rings so i hope they will fit as they are getting harder to find Dave
