FTR Technical Bulletin No. 004
Barrel pin (DOW-033)
To date there are some 300 FTR type gearboxes in service.
Of the initial batch of some 20 gearboxes a quantity of the selector barrels were fitted with sub standard pins (see tech bul-
letin # FTR 03). This fault was quickly recognised and dealt with. Since that time there have been few instances of pin fail-
ure. However, during the course of remanufacture, for our stock, we have taken the precaution of strengthening the pin.
The new stronger pins will supersede the earlier version for all new supply, and are recognisable from the earlier version by
an identification dimple in one end.
.
It is not our recommendation that all original pins be changed, but should you so wish, the new pins are available under the
same part number through your normal Hewland supplier.
As all existing stocks have expired, with effect from this bulletin, all DOW-033 obtained from Hewland Engineering will be
to the new specification.
