[QUOTE="melli, post: 97772, member: 7164"] Ok, got all the pressures... Everything is within specs, albeit on low side, except Main Relief on Manifold block (P2 & P3) - 3300psi (range 3400-3550)). Was hard to get swing over relief as I couldn't get lock on swing to engage, so I used blade as a stop, and arm was fully over relief. Looks like I can adjust main relief to get some more oompf. P1 was 2600psi (boom offset at full relief gets me that number). (range 2550-2700psi) Swing motor (P3) gave me 2650psi going both ways (2650-2950 range). So, generally, all looks good...other than Main Relief has some room to play with. Looking forward to actually adjusting that, as it may give me more oompf on swing and arm. To tuckered to pull out tools and adjust right now...will update once I adjust. Really glad it appears I have no major issues. [/QUOTE]
