hey, so im assembling my motor and have a small problem. its a 2.4l crank with i-beam rods and when i turn the crank the rods are hitting the cylinder wall. i know you have to knoch out the inside for the crank but has anyone ran into this problem due to the thick rods?

if so what did you do? im prolly just going to put a small knoch at the bottom of the wall sence it wont harm the perfromance of the vehicle.

thank you
martin

 

no one ever have thins problem? cant be only me. maybe i did something wrong.

 

bump

 

so no one has had this problem?????

 

You having a conversation with yourself?

You will need to notch the block to clear the rods. You should have a professional engine building shop do this as it is very specialized.

 

Hahahah...dont all jump in at once.


I use Pauter rods for my builds (mostly) which are very very wide at the base and even on the 2L i take a bit off the edges of the sleeves to ensure a fair gap for swing over.

As long as you are reasonable and dont take lots off you will be fine. Try stick to a low angle and not go too far into the sleve. Clean the block out well. I usualy mask it up in the area i die-grind so i can control the mess. Also makes it easier to clean up.


Were you to have used Pauter rods on a 100mm stroke you'd have to take quite a bit off there and as there is an oil channel on the one side you need to be cautious.

lol it's not really a "specialized" operation. I did it myself, ya just grind off enough so that your rotating assembly can rotate freely. Don't take off TONS of material, but take off enough so it will NEVER hit even while at hot temps.

 

thank you. the last two post def answered me. just wanted to know what others did. thanks alot

 

i would assum that this is on the side the oil squirter is on?

 

BTW also be sure to bend the oil squirters, or place washers underneath them so that the piston doesnt hit it when it goes down!

 

thanks, i did not know that so i will do that too
