CF. We’ve been through all this before. The Eaton Twinsplitter and indeed the 18sp Fuller were designed to be used without the clutch. That’s the whole point of having that torque-breaking feature. Eaton-Fuller are the same company and those two gearboxes are simply a development of the RTX and before that the RT, all of which you could safely use without recourse to the clutch. I know from previous discussions that you’ve never used either a Twinsplitter or and 18-sp Fuller (I haven’t used an 18-sp Fuller either, but I have long Twinsplitter experience and the mechanism for clutchless changes is the same). Long ago on a probably now long-lost Twinsplitter thread it took me pages to convince you that you were incorrect. You just go round in sanity-challenging circles mate!
EDIT to add that I’ve found the Twinsplitter thread and bumped it up. For those who are new to TN my user name was robert1952 then.
I don’t think we ever got the twin splitter, definitely not on any truck in the heavy end of the market. Some lighter vehicles had what was often refered to as a Jap RoadRanger, either a copy or (probably) licenced built 12 speed.
My understanding is that these 'boxes were a 12 speed version (torque rating apart) of the 13 speed, only lacking the crawler gear. The 18 speed is just a 13, that allows splitting the top four gears in low range.
I never liked the twin splitter i prefered the 13 speed Fuller in the Turbostars we ran. On a completely different note some of our Mercs (Hitlers revenge) crunch gears and they are autos . Progress hey!!!. We have a few Scanias now mine is a bog standard R450 auto.It’s ok the basic seat is uncomfortable with no lumber adjustment but the motor is decent enough.I have been using a newer R460 for the last couple of days with leather seats and overdrive auto box.Travellng at 56 on cruise yesterday at 40 ton on the flat it changed into overdrive and was running at 1000 rpm then it decided to change back down to 12th then back up again .This continued for a while.How can this be good for fuel economy and is 1000 rpm ideal to cruise.Mine sometimes drops to 800 rpm before it changes down , i just overide it now and change down myself . Why oh why can’t i have a manual
As I have said before on here, autos are sooo much easier, just sit back and relax and let the truck do all the work.
Perfect for somebody who is never in a hurry, …and if you don’t get away as fast as you could with a manual…who tf cares anyway ?..
As for fuel, it is for your boss to realise he has specced up wrongly, not for you to worry about. ?
For me?..
Yep…Anything for a quiet life these days for somebody with very little actual enthusiasm and interest in the job nowadays, and who has absolutely nothing to prove anymore with the use of most manual boxes…Been there done it all, and moved on.
Scammonden Dam , up on the M62. They were running just water (from Keilder)some years ago during a drought. IIRC driving hours/tachos were suspended. My eldest lad earned a lot of money at the time, he did tell me how many loads he did (but I’ve forgotten) 1995
During the 1995 drought, the reservoir’s water levels were so low that the base of a water tower was visible. To supply water to the reservoir, 1,000 tankers were used to transport water from other reservoirs. Bradford came close to running out of water completely.
That last paragraph Robroy sums me up perfectly.As for saving fuel i couldn’t care less it’s just annoying when it changes up and down all the time. My boss speccing don’t make me laugh he hasn’t got a car licence and after nearly 7 years doing this job knows no more than he did when he started. His boss who deals with us on a regular basis asked our longest serving driver if he was an artic driver yesterday .That was a hour after ringing him and asking what trailer he was pulling. No joke our place is on another level yet to be equalled anyehere else
The splitter gear train and its activation and selection mechanism isn’t the same thing as the actuation and selection of the full gears.On a twin split you’ve got 4 full double ( de ) clutched gear shifts.On a 13 speed or 18 speed it’s 8, 9 counting crawler downshifts.No one is saying that clutchless shifts are impossible.It’ just not good practice hence the ( correct ) magazine title.
IIRC this motor was bought by A.E.Parker of Chichester who used to haul Shipham’s fish paste but not put on the road when purchased, they had it stashed away and never put it into service until much later, many years in fact as they had to recommission it when it went on the road, does any one else recollect this, Buzzer
superb, best free entertainment on t’web. Truly a class act.
