--------------------------------
Removed the EB. 857 connecting rods, non drilled up type with lead bronze bearings and fitted in their place a set of EB.2260 drilled up type with lead bronze bearings (diameter of crankpins were found to be 1,2,3 & 4 = 1.99775 and 5 & 6 = 1.9975)
Diameter of lead bronze bushes were 2.0005", which left a working clearance of between .00275" and .003".

We have advised the Repair Dept. under seperate cover.

Sr/VA.
