*****Useful modification for 3TA, 5TA & early T100A engines*****
Triumph 3TA, 5TA (and early T100A) engines where originally equipped with a layshaft bushing (57-1367). Using this layshaft thrust washer (57-1607) and needle bearing (57-1606) you can eliminate the layshaft bushing. You must ground down the outer diameter of the layshaft thrust washer so that it will fit. This is a very useful modification/upgrade for your 3TA, 5TA or T100A engine that will add a much longer life to the transmission.
