Doing a project on a 463 G 300 TD and I need some info..Maybe G-users could help?
So first of all - hello! Now my question. I am doing a theoretical project on a 1996 - 2001 W463 G 300 TD(i need a W463 with a diesel engine and manual transmission) or just this one:
http://www.carsdatas.com/Mercedes/G-modell_(W463)/G_300_TD_(463.330,463.331)_(5_dr)_(177_Hp).html
and i need to know what are transmission gears/transfer case/both differential ratios..I've searched through forums and it is strangely hard to find the answer you need (at least for a newbie like me) - because it is a little bit confusing (there are many variations of W463). Maybe someone here would know these ratios for exactly this model? It would be good too if it had an "official" source - like manual, or at least scanned page(tried searching for them in forums but mostly the ones i need are to be bought - and for now i don't have the opportunity to buy one), because i will need to "back up" that information. So maybe G-users could help? I would appreciate it a lot.
hello and welcome ,what sort of project are you thinking of? the transfer case is 1 to 1 in high range the only higher ratio is the transfer box from a g350 463 which is .75 to 1 in high ratio /diffs i am not so sure need a chassis number to use to verify or the info off the diff case/housing -really need to know what you want to do then the more technical members can help you with more focussed replies.
good luck in your research,it may be better not to mention that you will never carry out the work as it could hugely reduce the return of info as those who have the knowledge of how to go about this kind of work may well not want to spend time helping on a project that will never ever get done . i would google 'portal axles on to g wagen' and go from there - best of luck
Thanks for advice. Well, i will not bother much,it would be good to just have manual and/or ratios from the components..From there i'll start myself,and, maybe someone will be interested in the results. If not, well, at least i tried.
i have just finished converting a petrol powered 300 ge 463 i will get the diff ratios off the casing and the wheel size /the gearbox will not help much as it is a 6 speed the merc code is '716.651' this will get you ratios to get you away ,the original auto box before we went to 6 speed manual had only got a 4 speed with a 1 to 1 top gear which meant the g was revving at 3500 rpm at 70 and over 4000 at 80 mph -no good for big pokey diesels. just one more point , we never got the g 300 dt 463 over in the uk as they never made it rhd ,there are one or two over in the uk so my info will be for a 463 petrol / i think the 463 300dt has tall diffs or a 5 speed auto so the info will be flawed as i do not know the spec on the exact model you are basing your 'project' on.
Well, i am searching a W463 with a diesel engine and a manual transmission(these two are a must), and that one just fitted perfectly. Plus the engine had a good power. Hmm, so G 300 TD came just with automatic transmission? Heh, it's very hard to find a W463 with a diesel engine and a manual transmission, i don't know why, but searching for a Mercedes G automotive gamma its very confusing(even wikipedia just has information about engines, but not about what transmissions had older versions). Maybe someone could point me into direction to finding that model?
I know that portal axles is not offered be Mercedes Benz, and thats why i've chosen Mercedes G - my main goal of the project is to study and calculate how can off-road capabilities be increased in a SUV - and Mercedes Benz G W463 has just incredible potential(full wd, 2 diffs) . So to increase it even more, i've decided to project a portal axles, because it increases ground clearence. Plus thats why i need a W463 with a manual transmission and a not "weak" diesel engine. But to project portal axles efficiently, i first need to know all the ratios of those components(both diffs, transfer case, gear ratios), that a car could reach a reasonable speed in a 5 gear and i could choose a reasonable gear ratios of portal axles.
I am aware there two schools of thought, one for manual transmission and another for automatic transmissions.
I fall for automatic transmission as it offers some advantages even for off roading. The torque convertor has an advantage of a 4:1 ratio conversion making it easier for hill climbs and general off roading. But if you insist on manuals I will try to help you there.
Yes i am aware, and im not saying that one is better than another, it's just my own preference too, and thats it. Thanks, your help will be very appreciated.
Mark has a 300td 463 lhd obviously when hes awake from his afternoon nap he may comment on this but then he might not
Will this site be of help?
his nap might last much longer than just an afternoon ... just so you know
Thank you for this site, but every 1996 - 2001 G 300 TD there is with automatic transmission - does that mean that G 300 TD didnt had manual transmission? And even every W463 model from 1995~ is with automatic transmission.. Is this mean that W463 didnt had new models(i mean from 1996~) with manual at all? Maybe you would know do W463 had some variation with a diesel engine and a manual transmission starting from like 1997 year?(i mean from your own expierence and knowledge)
Thanks, no problem i'll wait.

Yes, that's right, no more manual transmissions on civilian models in W463s. It is bad enough to get civilian spec. information but don't ask me to go the military versions, it is an up hill struggle as it is, anyway.
I will do my best for the variants on the W463 versions.
No, no need to go in a military versions, im interested just in civilians. Hmm, then its not good if there is no manual W463..
the only 463 300 diesel turbo manual are the ones i am building (with 606a engines ie. 177 + ps usually circa 200ps )
i have just finished the first 6 speed manual 606a powered 463 lwb (possibly the first ever unless ...)
you will only find data for automatics, basically the lwb 463 g wagen i have just finished is the one you need it has 200 ps and 370+nm of torque with its 606.962 6 cylinder turbo engine .
I have not been able to find the year of manufacturer at this point but forwarding to you what I have managed so far.
evening rakesh, what he wants doesn't exist -ie. a high power turbo diesel manual 463 g wagen (there may be one built by steyr for research or fun ) but this is all pie in the sky as the project is just hypothetical, shame as it could be a real bhuna!
I do appreciate that axel, and I think he knows it too,now. I am trying to give him part of what he has asked and that is the manual available in W463, which is listed above. As you say, they were not available in the mordern powerful versions.
Help People are getting squashed!

good evening guys,
Axel, how did that swap go? I ask because i got a 606.962 with the auto tranny to drop into my G in the next couple of months. theres a lot of info for the 617's but not much that i can see on the 606's
Any major issues?
to answer you joe, no squashing intended as 'learning' wants specific information for a hypothetical project on a vehicle that does not exist (not in production terms anyway) 'learner' wants a manual 463 300 turbo diesel ,manual,606.964 engine /along with all its gear ratios in the main 5 speed box/ then the ratios in the transfer box hi/lo and then the diff ratio- slight problem with this no such vehicle exists /the nearest is mark (of the green sprinter) who has a lhd auto 463 /606.964 ,but 'learning' must have a manual hence they are out of luck for a real in the metal one - they can still do their project but they must choose a manual box from the list for the 463 that Rakesh supplied and then get their ratios for that specific box along with the standard transfer case ratios /diffs and get number crunching ..
To answer your question '280 ge' there are loads of issues /what auto are you planning to use because if it's the one that came with the 606.962 it will be electronic and you need a controller to run it . have you got a non electronic injection pump?is your g lhd or rhd (i assume lhd for canada??) you will have to alter the sump or order the 606.964 sump /oil pump/dipstick/oil baffles/gasket or drop the mounts down 40mm and alter the 'sedan' sump to suit the g/ you will need the factory engine mount brackets/intercooler/oil cooler/get rid of the old petrol pump at the tank/ have the injection pump built up with the elements from the electronic pump to get the power back to 177 ps or mor eif you want it/ make a throttle linkage /start stop vacuum solenoid to use the petrol igniton switch/the rev counter has to be made to to run from the hall effect sensor on the 606 using 3 pulses to earth per rev/alter the turbo to run a pressure operated wastegate/cap the egr system off (egr and wastegate/boost and throttle are all ecu controlled)/use the first piece of exhaust pipe to make a big bore custom exhaust system/ recore the 280 rad to have a hi -flow thicker capacity to cool the 606/the bottom raidator hose has to be thought around if it's a left hand drive vehicle some of the problems are not so bad, but it is a major engineering challenge -it is so sweet when all is done though - a fine machine and what an exhaust note - oh and i forgot you get twice the power and torque/ half the fuel consumption..
'Learning' check your PM.
Talking of Portal axles, I believe early conversions on G-Wagens were achieved using the axles from one of the smaller Unimog variants.
Today, of course, there is a suitable portal axle around, but whether it is easilly available is a moot point. They use them on the G6 63 6x6 which in turn is derived from the Australian military G range. I suspect the budget for a pair of those would be a bit daunting.
The Pinzgauer was mentioned above as a vehicle which sports portal axles, which, of course, is correct. However, the Pingauer's axles are integral with the centre chassis tube so the only feasible way to build a G with portal axles utilising them would be to drop the G's body on to a PG chassis. It has been done before, but using a Toyota Hi-Lux body onto a PG 6x6 chassis.
Good luck with this project of yours.
Thank you all for help, it's much clearer now. I'll ask for teacher if its possible to do a project with a swapped transmission - if it is, i'll start doing it. Thanks again, you all have been very helpful.
Axel, thanks for all the info and the pics that 606 sure looks nice in there. You've given me a lot to think about, maybe i should attempt something a bit less ambitious at this point. given the fact that I want to get my G up and running this summer and i still got a lot of work ahed. I may take up a friend up on his offer for a 603 that he's done some work to it and drop that in as my first swap it should be much simpler and faster to get rolling. I'll keep the 606 in the car and keep that going for a few more years, who knows maybe by then i'll have the wife or the boys convinced to pick up a G for themselves. I know I want another one but I better get my 280 runing again and soon i don't like to see it parked.
thans again, good night

Well the first thing i want to do is to project a portal axles on a G 300 TD - so at first i need to know all the ratios to choose right portal axle gear ratios and height(i mean, what will be the speed in fifth gear after putting portal axles, and how bigger will be ground clearance). So first thing i need is to know the ratios of all components. After choosing needed ratios and height, i'll then calculate which components will need replacements and upgrades to withstand bigger forces on drivetrain because of portal axles. By the way, this is just a theoretical project, no "real" modifications to any G will be made(thats why i am limited just to internet search to find everything about my chosen W463 G 300 TD). So maybe there is a way to find that information without real numbers on parts?
