857lover 291 #1 Posted April 30, 2022 hey guys it’s been a while since my last post about my k181 and i frigates is just do a full rebuild i sent the block to a machine shop and everything but when i took my crank there i asked if they could balance it because it has a hole on the pulley side and they said they don’t think it would hurt it and that they don’t have a balancer but what do you guys think will this hole mess up my balance on my crank and wear that journal and rod when run it’ has some scoring as is and i have no idea how long it’s had a hole in it. but the scoring isn’t to bad but i wanna see if you guys would just use it or not because i don’t want to put all this money in and later down the road have a issue Share this post Link to post Share on other sites
stevasaurus 23,076 #2 Posted April 30, 2022 Are they going to turn the crank and get rid of that scoring ??? I think I would be more worried about that. 4 Share this post Link to post Share on other sites

I think I would be more worried about that. yes they would i didn’t want them to turn it if it would be off balance and ruin it anyway Edited April 30, 2022 by 857lover Share this post Link to post Share on other sites
pacer 3,176 #4 Posted April 30, 2022 I wouldnt worry about the hole, modifying in that area is common when having loose pulleys/clutchs/etc. Now, that cranks journal needs some help!! .... 5 Share this post Link to post Share on other sites

I agree with others that the scored journal is much more likely to cause issues. 3 Share this post Link to post Share on other sites

lynnmor 7,576 #7 Posted April 30, 2022 I too wouldn't worry much about the hole, but if you want it fixed just make a snug fit steel slug to fill the extra opening, It will stay in place when assembled. Share this post Link to post Share on other sites
