Bill D 2,130 #1 Posted October 28, 2020 I have an M16 with what I believe is a balance gear rattle. Can I remove the balance gears and have it run without excessive vibration? I know this is doable on the K series, but have seen mixed opinions on doing this on the M series. Thanks. 1 Share this post Link to post Share on other sites

bds1984 1,479 #4 Posted October 30, 2020 I really didn't notice any increase in vibration in the K341 on my C165. That engine has a shaker plate engine mount so I couldn't tell beyond the norm from that. The gears were pulled based upon the recommendation of many people here who've made the same move on their engines. It is worth a look at them to inspect how they are. I've seen those gears let loose and take out a perfectly running engine. Share this post Link to post Share on other sites
The Tuul Crib 7,338 #5 Posted October 31, 2020 I took my balance gears out of the last two motors I had appart and really can't notice a whole lot of difference. Take them out and leave them out! Share this post Link to post Share on other sites

I've been inside of both K and M series and they are almost identical. The crankshaft is already balanced so taking out the isn't taking much of that away. There might be just a little more vibration but it's nothing overpowering. My opinion it's vibration therapy! Share this post Link to post Share on other sites

Interesting the part number for eh balance gears themselves are eh same between K 341 and Magnum 16.... Share this post Link to post Share on other sites
richmondred01 2,292 #9 Posted November 1, 2020 Yes Prfrederi I believe the concern is the Mahle piston in the m16 and the way it’s balanced. However, I remove them on all my rebuilds anyway. Unless the customer wants the balance gears back in on the m16 only. If so, I press new bearings into the gears, mic the pins and gauge the play with feeler gauge. Even after all that, I won’t guarantee the engine with them installed. All my personally owned k and m engines the balance gears have been removed with no issues.
