T5 Tranny to Flathead 6
-
I'm in a bit of a spot I guess. I have an 89 T5 five speed to put on my 38 Dodge RC truck bell housing that attaches directly to the frame with its “wingsâ€. My T5's mounting bolts go a bit past the flat face on the bell housing. The T5 is quite wide. I've tried to read as much as I can find about swapping this tranny, but none has gotten real technical on how to center it, how to make an adaptor, ETC. There is a fantastic blog out there from Don Coatney on his adaptation, and there is a lot of info in it that I will need. My problem is that my bell housing is shaped differently, and there is no space to drill holes. Can anyone point me in the right direction? I can't afford to have a shop do this. Thanks. I hope I'm not asking the impossible.

I'll try to help, but if confusion reins supreme, give me a call. First item is whether or not the t-5 input shaft is the same length or longer than the original. If it is shorter, from the face of the trans to the end of the splines, then you will need another bellhousing. The amount of shaft beyond the splines is required for restraint in a pilot bearing and there are several methods of mounting one in the flywheel if necessary. The trans must be centered in the bellhousing, this is done with the fit between the front bearing retainer and the hole in the bell. If the bearing retainer is larger, then the bell can be bored to match, but, if the retainer is smaller then a spacer ring must be made to fill the gap. The ring must be secured to the trans.
If your input shaft is longer than the original then a spacer will be needed for the trans, and the thickness will be based on where the splines engage the clutch disc. There is lots of latitude here.
Since you are dealing with a cast iron bell, new bolt hole bosses, if needed, can be made by piling up weld material and drilling as required. Brass works well for this. Some times an additional piece of bulk material can be welded in place. The critical parts of this, or any, swap is that the trans must be centered and the input shaft must engage the disc. Providing a pilot bearing and dealing with bolt holes is less of a challenge.
Some day I'll write a book on this subject, but in the meantime if you want more info call me at 541.617.0613
