Engine/Transmission (1994 - 1998) chater noise solved

[38flathead]

after a long bout of tring to figure out my loud chatter on my 96 12v that i've had since new, and yes i know that it is solid lift and its a diesel and yes they make a lot of noise(but good noise) the problem is solved. It turns out that my vaccum pump was indeed bad. motor still ran great but chatterd after removing the pump I found it extremely tight and missing about 6 teeth on drive gear had to remove timing cover to retreive broke pieces but was successfull. recommend stethescope . On this truck I had installed repair kit that was recommended thur club about 5 years ago. Don't know what caused problem but back to the normal chatter and loving it. Thanks for all your sugestions. spool up and be save Jim Kuhman

So, did you replace the vacuum pump with a new one?? Mine had half of one tooth missing. Pete at Gould gear fixed me up pronto.

vaccum pump chatter

yes I changed the pump seeing that it was bound up new pump has a life time warranty. I also changed the water pump seiing that it had 120000 miles on original it also has a lie time warranty that's good because I plan to keep the truck the rest of my life. Wait I mean I'll keep the motor the rest of my life I don;t think the truck will last that long!!

So you was able to hear this noise with a stethoscope used on the vacuum pump? or the gear case? Did you have any issues with accessories? as a indicator? the missing teeth were was on the gear drive?
