For owners wishing to restore their machines Union Jack Motorcycles can provide spares, painting or plating services. Should you components require cleaning, Union Jack offers a vapour blasting service, which removes years of grim from your cases, cylinder heads and barrels. Although not usually done, Union Jack is able to offer part restoration services to pre-1988 Triumphs.

Triumph Motorcycle Parts Number Conversion for Prefix Letters

In old Triumph motorcycle parts books you will find part numbers listed with a letter prefix. The chart below shows the conversion from the old letter prefix to the new prefix number you will need to order your replacement stock Triumph parts. For example, the part number E3974 converts to 70-3974.

In some cases you will have a part number that doesn't have four digits. For example, H519. You still convert the H to 97-, then just add a zero before the 519 to give you your full 4 digit part number, 97-0519.

Prefix Letter Prefix Number
D 60-
E 70-
E1 71-
F 82-
F1 83-
H 97-
S 21-
T 57-
W 37-
