Clark42 Posted October 31, 2020 Share Posted October 31, 2020 My name’s Chris and thanks for letting me join. I’ve always been interested in all old machinery but the main reason for joining is at the present I’m restoring a ww 2 Clark aircraft tug. I hope to be able to gain some useful information from this forum to help with the restoration. Probably the main area of concern at the moment is the engine which is pretty well shot. Thanks again for letting me join. Quote Link to comment Share on other sites More sharing options...
Rootes75 Posted November 1, 2020 Share Posted November 1, 2020 What engine does it have fitted Chris? Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted November 1, 2020 Share Posted November 1, 2020 Engine should be a standard 230 cu in T214 Dodge, almost every part is available. Accessories mostly standard 6 volt Chrysler. If the block isn't actually cracked or broken it should save. Clark made the back axle setup, but I think the main transmission was standard Dodge too.

Hi, the engine is the common six cylinder Chrysler side valve industrial unit with the engine number T112*68941. The main problem is one of the cylinders is really badly pitted, to much to bore out, it would have to be sleeved. The cylinders are really close together and I’m not sure if there is enough metal to allow for a sleeve.

Gordon_M Posted November 1, 2020 Share Posted November 1, 2020 T112 is the standard contemporary civilian ( and militarised civilian ) 1941-47 4x2 half ton truck engine. Pretty much the same as the T214 but it normally came with the three speed transmission, though it would take the four speed with some bellhousing tinkering. Engine accessories will interchange. That engine bay is set up for a 23.5" engine ( they came in two 'lengths' measured at the head to block joint, 23.5" and 25" ). The problem is the block was designed originally in the early 1930's for a smaller capacity engine, in both bore and stroke, and by opening up the bore as they did, you end up with two cylinder pairs that are very close together. It is always the head gasket bits between these two close pairs that causes problems, since it is little more than 1/4" wide. If the rest of it is fine, get one cylinder sleeved then the block decked. If you can find a spare one you can fit a T214, T215, T211, or T207 engine, but if your Clarktor has only three forward speeds you'll have to tinker with bellhousing, clutch, and so on. Sleeving a single bore much easier. If it is sleeved you should be fine, but if you are worried just click the radiator cap back part of a turn and run it unpressurised. The maximum radiator cap pressure on these engines was 4 psi. If you replace the cap with a higher pressure cap - bad things happen. Speak to Steve Rivers at Dallas Autos about bits, but be sure to mention T112. Quote Link to comment Share on other sites More sharing options...
