Rod Length?

Recommended Posts

James_R

I'm after the rod length of the XU7J4 engine, seeing how different it is to a Mi rod, also if anyone has the info the small end size on them would be handy (I'm assuming the big end is the same as normal.

 

Thanks :D

150.5mm between centres. Small end is 22mm interference fit (not bushed). But the big end uses a 45mm journal, not the 50mm of bigger XU engines inc Mi16

So there is very little difference between the XU7 & XU5 rods.

 

XU5 rods;

rod length 150mm

stroke 73mm

r/s ratio = 2.05

 

0.5mm difference in rod length (assuming the 150mm I posted for the XU5 rod is centre to centre), they have the same size big end & little ends.

Have you now?... :angry::excl:

 

lol, i didn't think about that, but yes of course!

 

So also, you could use any other Xu rod (150mm) in an Xu7 block to lose some CR? Ahh, but i spose from what Sandy said it wouldn't fit the crank... D'oh!

XU5 and XU7 rods are the same part and definitely 150.5mm between centres.

Thanks for the info guys, shame it's not easily possible to bush the rods for a 22-23mm floating pin though ;)

 

NExt question, anyone know the absolute TDC valve clearance on the XU7J4??
