putting my pitons on my rod is very very very tight.. im actualy marking the piston surfuce a bit trying to get them off. i know they shouldn't be pressed on.. the wrist pins fit just very snuggly... any tips, a little sand paper ?

 

what pistons/pins/rods?

 

eagles and weisco,

 

i have heard of some problems with that setup not really fitting together... you can take the rods to a machine shop and they can make them fit, or you can take em to the belt sander/grinder and do it yourself

 

going to do them myself, i was going to use a even surfuce, what grit sandpaper should i use.. also i should do then on the rod side, the piston side, or a little on all.. ?

 

use a belt sander or one of the round sanders on the little end of the rod, make sure you use a ball hone or some fine sand paper to clean up the edges so they dont catch the pin.

 

so how were you planning to balance the rods after doing a backyard narrow job on the little end?

 

it dosnt really matter... its a 180deg motor, balance isnt nearly as crucial as everyone thinks it is.

 

you know i cant think like that jason, you havent seen the place in a while, im surrounded by everyone elses expensive builds now. hafta be ****.

especially when all the oild from the head drains down the passages and drops on the the counterweights of the crank.. but I too am still **** and balance everything..
mike i need to borrow you rod end balancing fixture if you have one, if not i need you to make me one this week..

 

i dunno... i learned to build engines from the best there is, i have study'd and pondered it and cant think of any reason to worry with it.

In case you missed it, i agreed with you and gave people an example why balancing on a inline 4 isnt needed as much.. The oil from the topend drains onto the crank so it throws the balance completely out..

 

that was more of a reply to mike than you tbone... but yeah... oil balances things good

 

i figure if one rod weighs more than the others, particularly the pin end as that is purely reciprocating motion, then by 9k, it will have a good deal more effective mass than the others and could be the heavier pulse in the cycle.. i imagine it in my head as being the heavier "beat" for the balancer to dampen.

and i do my best to keep oil off the crank.

tom- i made a balancing swing a while ago, youre welcome to come grab it anytime.

 

sush mike
