Allis 7000 Black Belly Transmission Lube Pressure

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic


   Does anyone know what the switch setpoint is for the transmission lube pressure on the black belly 7000's?  It calls for PN 70268428 which is on backorder and only used on black belly 7000's.  The maroon belly calls for 70240150 which was used on some of the D series and 170/175 and appears to be around a 6psi switch.  The bigger 7010+ call for PN 70268784 which appears to be a 12 psi switch.  I feel like the black belly 7000's had a higher set point than these other two options, but cannot seem to dig up the old post I have in mind where it was discussed.

	Found this, not sure it was the post I was thinking of, but the numbers seems to ring a bell in my head. I thought I remember the black belly 7000 having the highest switch point on the lube oil pressure switch of all the 7000's and 7010-8070 series. Looks like it's minimum is 15 psi. https://talk.newagtalk.com/forums/thread-view.asp?tid=129711&DisplayType=nested&setcookie=1 Hurst Edited by Hurst - 16 Jul 2024 at 6:18am
