Dodge bro Posted August 15 Report Share Posted August 15 I have a 1950 B2 fluid truck, it is running I put it into gear (1st and Reverse) as I let the clutch out the truck starts to move then with clutch completely engaged it wont move. Looking for advice on where to look. Any guidance. Quote Link to comment Share on other sites More sharing options...
JBNeal Posted August 15 Report Share Posted August 15 Have ya tried jacking up the rear axle to see if the wheels turn when engaging the clutch in all gears? Quote Link to comment Share on other sites More sharing options...
Dodge bro Posted August 15 Author Report Share Posted August 15 Not yet. The truck ran well then sat for 14 years. I gave it to my daughter and her husband because they wanted to restore......and now I have it back. Quote Link to comment Share on other sites More sharing options...
Solution Merle Coggins Posted August 16 Solution Report Share Posted August 16 Have you checked the fluid level in the Fluid Drive? It would have to be quite low to act this way, but it may be something to check. You'll need to remove the toe boards and trans cover parts of the floor boards to access it. There'll be a round cover in the bell housing at around 1:00 or 2:00 position. The cover will pop off and expose access to the level/fill plug. You'll probably need to slowly crank the engine over until you can see the plug through the access hole. Then CAREFULLY remove the plug without dropping it. A magnetic socket is helpful here, or put a paper shop towel over the plug, then press the socked over that to make a tight fit as you remove the plug. This will help hold the plug into the socket for removal. Once you have the plug removed you should be able to see fluid. The fluid level should be right up to the level of that plug hole. Official Fluid Drive Fluid is obsolete, but I am using an AW32 tractor Hydraulic oil in mine and it's working just fine. The next thought is... if the level is low, why? Is the bellows seal leaking? Or did someone drain it at some point in time and didn't refill it? Quote Link to comment Share on other sites More sharing options...
Dodge bro Posted August 16 Author Report Share Posted August 16 Thank you, I wasnt sure how to check the level, the motors and chiltons shop manuals I have from 1951 didnt provide instructions how to check. I will check tomorrow. is there a straight forward way to remove the fluid drive from the drive train? Would I need a different clutch and transmission (have 3 speed currently)? Thanks so much for the advice and instruction. Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted August 18 Report Share Posted August 18 The transmissions used with FD have a longer input shaft and nose cone. Also, the bell housing is longer to accommodate everything. To switch to a conventional trans you’d need a bell housing and flywheel at minimum… besides the transmission, or shorter input shaft and nose cone Quote Link to comment Share on other sites More sharing options...
Dodge bro Posted August 18 Author Report Share Posted August 18 Thanks for all the info. I filled the fluid drive and drives well...or did until new fuel pump stopped pumping. I have a new fuel tank and such on the way so sould be close to driveable. I will keep fluid drive for now. Thanks so much Quote Link to comment Share on other sites More sharing options...
greg g Posted August 19 Report Share Posted August 19 Your truck probly has an unsynchronized trans. The fluid drive should be easy to leave in 2nb or 3rd and just drive around using gas and brake pedals. Quote Link to comment Share on other sites More sharing options...

I'll just leave it in 3rd and use brake/gas. If I need to start out on an incline I'll drop down to 2nd, but otherwise 3rd works fine. Once I get out of town where I'll be going over 35 I'll then double clutch and shift up to 4th. Quote Link to comment Share on other sites More sharing options...
Dodge bro Posted August 22 Author Report Share Posted August 22 It is unsynchronized and love the double clutch. I have left it in second and driving it around. Quote Link to comment Share on other sites More sharing options...
David A. Posted August 22 Report Share Posted August 22 I was thinking the B2 three speeds were all synchronized. I know mine is. Quote Link to comment Share on other sites More sharing options...

How much oil did you have to add/how low was it? Quote Link to comment Share on other sites More sharing options...
Dodge bro Posted August 26 Author Report Share Posted August 26 I added a gallon. I cant find any leaks. I degreased the area and have fresh paper under the vehicle. Nothing to this point. Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted August 26 Report Share Posted August 26 That's quite a lot for not having any leaks. I couldn't find a spec for the fluid capacity. I suspect that someone drained it, at one point during some 'maintenance' to get it running, and never refilled it. It might not hurt to recheck the level again. I recall that it took a while to get mine full. It would get up to the plug level, then after a while it would settle and burp and I could add a little more. I had drained mine during the engine overhaul process and refilled it before reinstalling the engine back into the chassis. Quote Link to comment Share on other sites More sharing options...
