Will a T40 bellhousing bolt onto a T50 box?

Are the T40/50 the same.

Same?? as in what respect. The T50 is from a 2t engine and the t40 is from a 4A

They have different output spline counts from memory. EDIT: but pretty sure the bells should swap over

Cheers mate, I have a spare T50 for my ke20 but I'm building a ke70 for my wife and have a 4ag to replace the 4k but need to change the bellhousing to fit.

If you have a T50 to fit a KE20 drive shaft it may work in your favour.

Your 4a t40 will be a 22 spline vertion with large input bearing

 

2t t50 could be either a 20 or 22 spline (outputshaft) depending on age. Change was sometime in 82`

 

If its a 22 spline, 4a bell will fit. Ke20/ke70 driveshaft wont.

 

If its a 20 spline , ke20ke70 driveshaft will fit but input bearing will need a spacer ring to suit the bell.

 

4a bell isnt perfect for a 4age but many use it. Look at heatsheilding clutch slave cylinder

Thanks tojo2 Maybe we should pin this somewhere, Cheers.
