What is a David-Brown gearbox?

SoM had quite a few Guy’s with the straight 6 DB box,terrible things IIRC,had to wait what appeared to be ages between shifts,married with a ■■■■■■■ 220 it was a marriage made in hell!
What you gained with the engine you lost with the box.

Point of interest David ---- Are you positive the Big J’s used the DB box and not the Thorneycroft 6 speed I recall that the Invincibles used the DB 5:500 box but as always I could be wrong on both counts eh ! Cheers Dennis. :blush:

You may well be correct Dennis,I thought I remember discussing the relevant box with one of the “grease monkeys” from the workshop,I bow to your probable superior knowledge re gearbox’s,but not re Big Percy’s in Big Guy’s!

Stay well,

David

From painful experience £££’s the DB 6:600 was OK behind the 180LXB but an unmitigated disaster behind the ■■■■■■■ 220 of which we operated a number. One of the problems was not dropping out of O/D once the unit started to pull on the M/way grades . Cheers Dennis.
