The TES O-rings for the rotor side seal have been previously sizes by

Paul Lamar so I will give credit where it is due.....That said several of the group

have had problems with the sizes for the coolent seals..........To settle this once

and for all I sent a 13B side housing to "Creavey Seal" to be properly sized for

coolent seals........The following are the sizes that "Creavey' has on record for

the 13B.........It is thought at this time that the "Renesis" seals are the same size

but we are not sure yet........I ordered all my seals with the higher temp. PFA

Teflon........The outer coolent seal which does not see as high temps. could be

ordered with the lower temp. Teflon and would save a dollar or so per seal.....

..There is some question in the group as to the necessity for any or all of these

seals........I consider their use a relatively inexpensive upgrade of the oil and

coolent seals even if they are probably overkill especially the outer coolent

seal as it does not see the extreme temps. of combustion that the inner seal

and rotor side seals are exposed to.........FWIW
