Bobcat 7753 leaking Differential pressure switch

[sduker]

Hello, (new member here) I'm helping a friend with his 7753 that has cracked 1 differential switch (Part #6671062) and blown 1 apart at the crimp. I have a pressure gauge in the switch spot and am seeing 110 to 180 PSI. In the manual the switch shows 34-44 PSI for switch and filter bypass at 45-55 PSI. What should the pressure be at this point right after the filter? On a side note the machine had a cracked hydraulic pump replaced about a month ago. Shop said it was probably a bad casing? Thank you in advance for any help or suggestions

Hello, we ended up taking machine to Bobcat for testing as we could not find a spec for the pressure. They charged 4 hours labor to test pressures and said everything was in spec. I guess we had the bad luck of having 2 gauges go bad. Total waist of time and money!
