New to me 2019 CAT 305e2 with 1500hrs. All functions seem to work strong and fast except boom down lifting the machine. It can lift the tracks off the ground with the boom down function although somewhat slow. But with the blade down first and lifting the tracks on one side the boom down function wont lift the machine up. Sounds like bypassing the relief. An interesting observation: When im boom down trying to lift the machine and bypassing sound is heard, if i move the curl function even slightly, the boom down seems to work, lifting the machine. What causes this? Machine came from a CAT rental fleet. My local Cat service looked up the service history and saw no repairs or codes from the past, only routine service at the intervals. Maybe just the CAT is more week than i was used to and this is normal operation?
Good day The attached explanation may be of help. Kind regards Uffex
Thanks Uffex! So it might be normal operation if im "receiving full hydraulic pressure"? so to test for full hydraulic pressure to boom down function do i hook a gauge to my test port and boom down to relief?
Good day Yes sir full pressure is all you can have. Kind regards Uffex
Thanks for the help Uffex!
