Cranks - Can I Just Check!?

[brumster 135 1 Cars]

A wealth of searches suggests that all the 1.9/2.0 XU9/XU10 engine cranks have the same journal diameters across all years and derivatives. So, ignoring issues with piston height and rod length, any crank - an XU9J4, XU10J4, XU9D - even these 2.1 TD cranks like DrSarty uses - would drop into any of the other blocks. The journal diameters are the same on all of them, right? 50mm for the rod ends, 60mm for the mains, yes? I know there are issues with spray bar clearance, 4 balancing webs versus 8, steel versus iron, and the whole issue of the rod length/piston height depending upon what you slotted into what (due to stroke increase), but I'm just checking on the crank fitment itself - no-one anywhere seems to suggest there are any issues around this....? Correct?

Basically yes, although the iron block cranks sometimes foul the alloy blocks. The 2.1 TD crank has wider big ends than the others.

Thanks Sandy; understood

 

One more quick question then, sort of off the back on a thread in the Wanted section

 

Is the XU9D turbo crank the same as an XU9J4 (mi16) one? So 88mm stroke, 8 balance webs rather than 4 (if that's what you call them). My understanding is the non-turbo ones are the lighter 4-web cranks but I'm sure I read somewhere some of the diesels have the mi16 crank in them....

The non-turbo diesels are 8 counter-weight like the Mi16. Many (but not all bizarrely) of the 1.9 TD ones are 4 counter-weight steel ones.

just looking at this as i need a crank, so are we saying that a crank from a non-turbo diesel is the same as a mi crank? when you say about stroke, will it mean that i would need different rods if i were to have a derv crank and mi rods!!

if you stick to the 1.9 D crank, that is the same stroke as the 1.9 Mi, 88mm.

1.9d from a 205/306 etc etc??
