I am pretty new concerning cummins and parts...

Im going to buy a Bluebird FE 3600. Its a 1998 5.9 cummins 12v with a MT643 Allison Transmission.

I would be glad if somebody could give me some informations concerning the engine and the trans.
All I found in here was about the engine build in a Dodge. Can somebody give me some hints how it is going to be maintained, whats really necessary todo, maybe some motor specifications concerning proper oil etc. (btw. I am living in Spain, so if somebody knows a good oil that can also be bought in Europe...)

I would be also thankful if somebody could tell me about the trans. How reliable is it ??
At the moment its rotten up. (First and fourth drive doesnt shift)
What can I further do to give them some performance??

 

Welcome to db!! You will find a lot of useful info here. You will probably have just about all the info you can handle in the next 4 or 5 hours.

 

im sure a amsoil dealer could ship you the oil you need. look up the KDP problem and get that fixed first. welcome to DB

 

thanks to you both

well thanks for that hint guess its the first thing Im going to do! Just dont understand how it can be manufactured this way
concerning the oil: shipping would double the price I guess... What kind of oil is normally used? synthetic 15W40 or mineral?

 

some guys swear by synthetic some by the good old stuff. i use regular 15w40 rotella. i go 10k and change it on prinipals not wear. have fun with it

 

thanks, well I didnt drive it yet, but (sorry) I xpect it will be pretty poor... got a weight of 6.5 tons... therefore I am also interested in giving it a little more power.

First exhausts
second turbo
thrd trans cooler
fuel pump

and then depends the money...

 

Welcome to DB..

Can somebody tell me the difference between the MT643 trans and the trans theyve build into the dodge?

 

 

Welcome n enjoy your stay !!
