Hot Rods T5 to flatty adapter dimension needed

Does anyone have the length of the bellhousing adapter. Distance between engine and the T5. Am engineering a conversion, need this dimension. Thanx

 

I just tried to get you a measurement, but mine is installed. Roughly 3 1/4". Sorry, its only in the ballpark.

 

Firecat I am assuming this is for a flathead ford? What year engine are you looking at? The measurement will be different between an engine with an integrated bell housing and one without (again assuming that when you say "from the back of the motor" you mean distance between the rearmost mounting point of the motor and the mounting face of the transmission). I will be able to get you the measurement of a motor with the integrated bell housing (1939 )later today if that helps and no one else comes along . I've always just used a 3/4 aluminum plate between the doghouse and trans if that helps. The pic is of a 1949 motor without the integrated bell housing, I don't have it available right now for a measurement but you can see the 3/4 plate.

 

I'd suggest that you work in reverse order.
You know the length of the input shaft and you know where the splines of the shaft are so locate the splines within the hub of the disc. Generally, 100% engagement would be best but, with low hp/tq you can get by with less, how much less is up to the designer. The pilot portion of the shaft can have various amounts of engagement and the bushing/bearing can even be place in the flywheel if needed.

 

I measured a 8BA without an integrated bell housing. From the mounting surface of the block to the mounting surface of the T5 is 7", comprised of (steel stamped) bell - 3" and the (MDL) T5 adapter - 4".

 

For my 59A, I used a hog’s head adapter which is 3” deep, and a MDL adapter after that which was 1.1” thk to the T5. So, overall 4.1” from engine to front face of T5.

 

Some calcs I did for my setup on the length of the T5 input shaft

 

Thanx, your bout the only one that understood what I was needing.

 

yes, thanx.....4" seems to be a common.

 

Just be aware that there are four input shaft lengths for a Ford T5, and at least three for a Gm T5. Plus the ones used in Chevettes, Datsun, Panther, Jeep and many other applications, all with the Ford or Muncie bolt pattern.
