On nights tonight and got 4 con rods to fit. Might take a little longer and need a slightly bigger torque wrench than usual.....
The top two tiddlers are from a quite substantial hydrogen treat gas (To remove sulphur) compressor in the oil industry. The bottom two are indeed from a recip feed pump, but I'm not sure which one as they just happen to be in the same workshop. Have actually seen bigger ones in there a while back, approx 10 feet in length
