Size of holes in my JD 2010 Turbulence Chambers

danpaul1 · Apr 29, 2016

I took all four of my Turbulence Chambers out of my John Deere model 2010, I noticed none of the holes in the bottom of them were the same size the different's is any where from 3/16" to 5/16". My question does the different size in the bottom of the turbulence chambers matter?
Thank you

Sorry I forgot to mention I am speaking of only the upper turbulence chambers the lower part all looks the same as far as the size of there holes.
Thanks, DP

My guess would be the different size holes in turbulence chambers is due to different tractor serial number range. It's possible this question might be answered in a JD tech manual.

I'm afraid that I've made a mistake when taking out the four turbulence chambers, I did not mark which one goes where I assumed they were all interchangeable because, I did everything by the shop manual "Word for Word" that I have, the manual did not say anything about putting a mark on each chamber (So I would know the one that came out of the cylinder head hole #1, #2, #3 and #4 front to back or left to right standing on the left side on the motor). Does anyone know how I can tell which Turbulence Chamber came out of cylinder head hole 1, 2, 3 and 4? I used my "Micrometer" to check the measurements on each one of the chambers to see if they were different, they are not different in any way, I looked for any kind of factory markings on them that may tell me which chamber goes where and the only letters and numbers stamped on the chamber housings at the factory ("BH" on three of the chamber housings and the last chamber housing only has and "Arrow Symbol" stamped on the front of the housing).
Thank you

All parts of the turbulence chambers are interchangeable and it doesn't matter which one goes in which hole. Make sure everything is clean and you torque the nuts or bolts exactly to spec in tech manual.

I could not pull the lower section of the four chambers is that a factor? I couldn't change all the brass out, the only way to pull the lower section of the four chambers would be pull the cylinder head and I really don't won't to do that, this John Deere 2010 was built in 1963 so everything is stuck, because of how many years the tractor has been in operation.

You should change the copper rings and O-rings. If you don't you're liable to have a combustion gas and/or coolant leak.

I've changed the o-rings on all four upper chambers, and tried everything trying to pull the four lower chambers but I didn't have any luck. I also tried to pull the top brass washer on all four of the lower chambers, I couldn't get my picks to hook into them so I could pull and change at least the top brass washers. My question now is it that importune to change the two brass washers on all four of the turbulence chambers? The problem with me pulling the cylinder head, I will need to order all the gaskets and get them here before I even start pulling the cylinder head.
Thank you
