"Made in England" by AE Hepolite.

Supplied to MERIDEN Triumph at Coventry with number 70-9488/001"

These pistons were supplied to the TRIUMPH MERIDEN factory by Hepolite 

to tighten up new "loose" bores on the 650cc production line.

They are 0.001"inch (0.0254mm) oversize,
one thousandth of one inch, NOT to be confused with
 
XX NICH  XX  010"inch XX NEIN XX (0.254mm)
XX NON XX
XX NOT XX  ten thou oversize XX NOT XX

A $ bill, € euro note, or £ bank note is approx 3 thou thick.

These pistons will suit slightly worn bores @ standard size, 

or honed to size brand new bores

These genuine pistons are at Standard size plus ONE thou.

Original TRIUMPH Standard rings fit these pistons.

See my other E-Bay listing number 122504848143 for my six Standard size ring twin piston set.

See my listing number 123843308333 for 3 ring
individual piston sets.

Do NOT use 010" oversize rings, they are too BIG

 Pistons are supplied bare, WITHOUT rings, pins and circlips
These pistons sometimes have a dubious size stamp on the TOP.
The after manufacture stamping of .001" is often scruffy &  haphazard.

BUT EVERY Piston is Carefully Checked with a vernier gauge
AND on my Hepolite Piston Ring gauge before dispatch.

You will only receive STD 70-9488 @ + .001" (One thou oversize)

Pistons are matched, if possible, closely for the same batch
and production numbers, and the weight of each piston is normally
indicated with each individual piston.
