hey all,
i'm about to walk out the door to take my truck in to rocky mnt cummins to get my timing checked. other than the high hourly, anyone have any bad experiences or problems with these guys??

 

Are you sure they will do it?
I heard Cummins will no longer work on Dodge trucks.
One thing I know for sure is that Cummins will only set your timing to factory specs.

 

Maybe I'm missing something, and I've never worked on a Cummins, so maybe I'm out on a limb here, but how could your timing have changed? Wouldn't the pump had to have come loose, or the drive mechansim to have jumped a tooth? Either of those should be pretty self evident.

From here, it seems logical to check the overflow valve first, as suggested by Doc Evil, as it seems like the most likely candidate.

Just my $0.03 (inflation).

 

i don't know anything about how the timing works or how it would "slip", but it has been suggested by several people that that may be my problem. maybe running it with a bad lp could have caused some problems??? my truck has none of the symptoms listed for a bad overflow, but maybe i should just replace it anyway???
i'm going to call cummins now and ask if they'll check my timing and what it will cost.

 

just talked to cummins. they will do the timing adj and quoted $200 max.

 

On a lot of the 12Vs the nut that adjusts the timing was somehow not torqued properly and slips on the shaft....which in turn causes the pump timing to change.

 

i know the cummins southern plains still works on cummins trucks. That is the best place to get filters.
