740 Allison blowing spin-on filter seal

[plyonsMC9]

HT-748  - same filter / seal blew out on ours a few months ago.  What a mess!!  WW Williams had put that one on.  Didn't last but a 100 miles or so.  Bus was just idling at the time it blew out and hadn't been driven in a few days.

Lots of cleanup, new filter, and all ok.  Never did figure out the why. 

Strange -
Kind Regards, Phil

LOL, yeah 10-4 on the mess.  I had to back up a couple feet in the fuel islands to line up the pump and what the *&?#@!, a massive oil down.  300 psi and ATF will do that.  I walk in and ask for the manager, he comes and I apologize profusely and he says ah don't worry it happens all the time I'll get a kid out there to clean up the oil spill.  Man, ya gotta love Texas!

Yep, was just backing out the driveway.  Not sure if it had anything to do with it, but I didn't let it warm up as long as usual because I was in a hurry.

Were you in reverse when it blew?  740s put out more pressure in reverse, like Cliff said around 300# or  more.  I blew a Luberfiner filter on a 740 behind a 6V92 a few years ago on a Vogue I owned for a few months.  Never did like Luberfiner filters but it was on the rig when I bought it with only about 500 miles on it.  Just wrote it off to a bad filter.  That was a first for me but it's not unheard of.

Oh my, that'll but a damper on your day.
Makes me think I need to carry a couple 5gal buckets of trans fluid along.
