Working on a 2000 L-36. Which way does the connecting rods go in. There is no arrow on the piston like some of the V-8's. There are stamped numbers (699) on the rods and some letters on the piston top. Can someone help us out.

 

the bigger end goes on the crank

 

^^^^^man that's cold

 

the smaller end goes on the crank also, *******

I'm sure he knows that...I think he need to find out what side of the piston and rod face the front

 

Shouldn't matter. The L36 have dished pistons so there shouldn't be a way for the valves to hit since the whole top is pretty much a valve relief.

 

Thanks for the help MKCoconut, yeah, the manual says that the rod can go in either way. I was just trying to put them back in the way they were from the factory.. if possible.

 

always mark your rods using a punch. sorry for the after the fact advise. i use one mark for number one piston, two for number two etc. put mark in same spot on each so that it shows which way it was positioned.

 

As Craby suggests, center punch the oil pan rail side of rod and its cap as to the cylinder it originally resided, or number stamp, aka, 2-4-6, etc.


Yes there is a certain piston/rod assembly goes into cylinder.
Piston may have a notch on the top edge and notch to front of engine.
Piston also has a heavy side and light side about the wrist pin centerline.
Wrist pin is offset in piston - heavy side to center of block.
This offset counters the power stroke on the piston making the piston 'straight' in the bore - not lop sided.

 

yeah, the piston/rods were marked as to which bore they came out of,. The rods were never separated from the piston. Just want to get the piston back in the way it came out. There are arrows on the under side of the skirts that would point to either the fender or intake, not the front or back.
His marks for bore location are not systematic as for which way they came out, only which hole to put the da*@ thing in.
