have on old book for garageworks, and it mention twospeed axels to all modells L36 L55/56 L66 waht is a L76 motor whit the7.8l and L75/76 LB76 ,only the year,s avalebul are not mentioned.but could still bee that the splitter was lansed 64 and 76 in 63.means it,s a very small number of the motors whit this spec,so they in a way are not “notified” in historic
Lindh’s book seems to make sense on this. It says that all models in the L75 series were “equipped with the G660 five-speed gearbox and with the option of the new T2 two-speed, synchromesh auxiliary box…” Moving on to the L76 series, it says, “The trucks were available with the T2 auxiliary box until April 1964.” Then, “a new five-speed gearbox (G600/G601) was introduced in April 1964… this was the main element in the G670/G671 splitter unit…” It then mentions the questionable pneumatic operation of the splitter which, I think we are agreed, did not come into the picture until the L110/LB110 models. It seems that all 10/11 litre vehicles had the splitter/auxiliary box on the gearbox, whereas the 5, 7 and 8 litre engines used a two-speed axle, if they had 10 gears. Maybe the T2 and later G670 splitter boxes were, for some reason, not compatible with the smaller engines?
On the subject of two-stick LB110’s, Lindh says, “In September 1968, operation of the planetary unit was transferred to a small button on the main gearlever…” The Commercial Motor article I found implies that the first LB110s with right-hand drive were delivered in July 1968, and the article mentions that the splitter was operated by a switch on the stick, although it says that the switch was difficult to operate and that later vehicles would have it nearer the top of the lever. It seems that the LHD LB110 had two sticks until September, but RHD markets had the switch from July; there were no RHD two-stick LB110’s.
I knew there was a reason why I chose this username
