But, it is the reverse of what you're suggesting. There is less danger of overspeeding with high oil pressure.

I assume one of them is at the back of the R2 governor's oil pump? Where does the second one go? I don't intend to change them myself - just want to know. Also, is there any danger in overspeeding the engine when changing these springs (considering they just raise the pressure)? Thank you.

From: M=E1rczy Marcell Sent: 30 June 2020 11:02 Subject: MT spring installation Hi Richard, First and most important is you can install MT springs only into 4th series governors. You can check the top cap and if "IV" is written then it is a 4th one. (we meet before that it cap itself was 4th one but the governor inside wasn't .) To change the bigger spring, you should take of the top cap by the 4 nuts. Then take if off and easily change the spring. On the drawing it is number 21. It is simply standing there, nothing special. Then put back the cap and fix it with the 4 nuts. To change the smaller spring, you should take out the reduction valve's nut out on the side. The nut is not on the drawing but it is at number 17 and on the photos as well. Simply change the spring number 12. Then put everything back. Now, when we do this change, we test the governor on our bench to adjust the spring with the washer number 17.To adjust the oil pressure that needed for the propeller. That's why the best is doing it at Aerometal, but there is not that big changes in pressure, so the propeller will but blow up, so you can change it, but surly need to check more times before flight.
