That's broken

[Harrison]

Cam gear looks and feels ok, pump gear does not. Hopefully that prognosis stays the same once I pull the timing cover off. Would not enjoy doing cam gear in the truck!

Could be worse I suppose.

[M4wdFab]

why would power be down though if all is ok hmmmm


vac or PS pump seized? what would cause that?

[mr.mindless]

Catastrophic failure like that could have caused pump timing to suddenly slip.

I think my pump gear went with my pump. I think I still have a cam gear on my hot rod cam, and a stock cam that's fine.

[Harrison]

Have not pulled front cover, but the cam gear looks and feels OK. Pump gear (can't actually see through vac pump hole) feels like the same as the vac pump gear, kinda gnarly on the edge of the teeth. So planning to replace that, hoping I can get away without replacing cam gear as that would suck to do on the truck. Thanks Mike, I will let you know. My guess is that the cam gear was continuing to spin the unconstrained vac pump gear and forcing it up into the injection pump.

Idk if I noticed power being down until right before I shut it off and it was clearly misfiring, could hear and feel that. Could slipped timing make just one cylinder off? I wouldn't think so. In the few minutes before this all happened, I may have been seeing an occaisional random puff of smoke from the tailpipe. Maybe I was losing an injector anyway and it didn't show up until I stopped... completely unrealted.

I think I need to get it back together, timed right and go from there. I really don't think I hurt the pump.

No, outside of something else being weird. I guess if it was WAY off, to the point of missing, one might die before the rest if its injector or compression was a little off from the rest. It might feel like one hole dead even if it's just missing gently all over.

Agreed on putting it back together, running it, and seeing.

Id aim for 18* timing running alternative fuels, if not a little more. I ran mine between 16-16.5 and it was pretty great there on #2.

[Harrison]

18 was my goal as well per Chad's suggestion. Interwebs agreed saying that 16* worked well for 215 pumps and the smaller pumps (like my 175) seemed to feel really good with 18*.

These are intriguing. $30k for a 4x4 base model. Seems like it could be good for a DD/once a month towing machine. Could sell stuff and save for a bit and have a good down payment.

a. sweet!
b. boooooo DEF
c. sweet!

[jacel86]

DEF isn't bad....until it is. :-)

[Callelle]

Why is DEF bad? I just see it as an extra fluid to keep up on with regular maintenance.

[jacel86]

When it works it's great, and easy. Once the filter starts going downhill it gets expensive fast. If the bake/pressure clean of the filter doesn't work you have to replace the whole thing usually.

[rejeep]

Why def?  Why catalysts? Why low sulphur fuel?

Old mechanical diesels use to run forever with little maintenance...

That's why it all sucks

[dubt]

The trucks my dad saw at Peterbuilt were putting out cleaner air than what it sucked in when the system works right. In real life the truck s go in to regenerate mode from Def  filter issues

[rejeep]

We have how issues because of regen....  Don't know how the real trucking world is dealing..  It makes my life miserable.
