For the original Ariel rods it is 260 ins/lbs so divide by 12 for ft/lbs. This comes from an Ariel Works drawing which gives the only 6 known torque spanner loadings for Ariels.

The end float for the cranks (ie measured on the timing side main bearing) is 0.002" to 0.004". This is quoted in Waller, but in the section on twins rather than the section on fours. But both twins and fours use the same timing side bearings.

I'd assumed for some reason you were fitting new, club rods.

It will be well worthwhile fitting new rods if there is any doubt about the ones
currently fitted. If one lets go it will wreck the engine.

Whilst still in preaching mode, the oil ways ought to be 'clinically clean' too.
