DT466 Oilpump
#1338063 - 08/10/03 07:58 PM

I have a 1980 International never had to work on it much exept i had to put a turbo on once so most of my mechanic experience has dealed with gas engines. It has a DT466 210hp 5/2sp it makes a knocking noise from the front of the block so i took off the front ent radiator..ect. i took off the crank pulley and found the oil pump the needle was jumping around and hand no pressure at idle so i thought it was the oilpump any body know how to get it out once i get the front cover with the gear off

Also is the oil pump that knocking sound it goes up with the rpms.
p.s. anyone had problems with breaking spedo cables?

hmmmm, I ahve a wierd knocking/ticking sound on my dt-466, kinda sounds like an faint exhaust leak, it's not always there but sometimes is louder than others. I'm not sure how to help you technically with the dt-466, I've only had mine a year and havent had any engine problems. there are some guys on here that know a lot about the dt-466 they should be along shortly.

Pull the damper off and the oil pump is behind the damper. Six bolts and the front half of the pump will come off. Remove the crank key and than the back half of the pump will come out. I would be surprised though if that is your problem. If you have a knock it is probably a spun rod if you have no oil pressure. The other knock from these engines is a piston knock from overheat, but this will not effect oil pressure. E-mail me if you have questions as I am only here periodically. Have worked for International for 15 years and rebuilt hundreds of DT's. Don't know everything but am very comfortable on it.

Was there metal in the oil pan? If it is a bearing it should have put bearing material in the bottom of the pan. If you did not remove the rod caps to inspect the bearings than push on the caps and see if there is excessive movement. I am not sure why you are having problems with the oil pump because once the key is removed from crank the back gear and plate come off. Maybe you are trying to remove something else? Do you have the front cover off? If you do, than you have already removed the oil pump.

Just to ad to this conversation ,You could also have a bad injector!
Did it smoke more than usual?Pull the injectors and have em tested!

thanks i'll try that
would a spun bearing cause the oilpressure problems?
it has no pressure a idle but around 1500rpm it starts jumping around like crazy any one also had problems with breaking spedo cables

Let's start over. What exactly is the complaint. You said you have no oil pressure and a knock. Or is it a ticking sound that could be coming from you tach cable that comes off the fuel pump drive? Have you checked with a manual gauge to verify that you had no oil pressure. The red warning light on the dash should come on when pressure drops below 10-6 psi. What was your oil pressure at full throttle? When hot it should be above 30psi and at idle above 10. Trying to help but need a little more info.

the truck place tested it with a mechanicle guage it has very low pressure at idle the other trucks all have 60-90psi and when full throttle the needle goes to normal but jumps around crazily

At low idle do you remember the reading? was the engine warm or cold? Cold it will be up around 60 at ilde but when hot it will be in the 10-30 range. The jumping around is probably just the gauge or sender, would not worry about that.

ok
i found a little piece of metal in the pan
if it is a spun rod it is the number one rod because the sound came from the front of the block
how much would the bearings cost?
would that be all i need?
any body every had problems with breaking spedo cables?

F series if ya got a bad bearing you aint gona just pop a new one in there!Pull the cap and look!Your dabling, ya need to jump in with both feet! If the knock is that bad and you have lost oil preasure you need to confirm it isn't a bearing before you make that crank unusable.if you stop now you may save the crank and you MIGHT get by with a bandaid . Pull that pan again and Check 1 and 2.

The bearings will be cheap compared to getting the engine out and on its side in order to get the crank out to have it machined!

Please do not be offended but it sounds like you are getting in over your head. You need to have the confidence to go in there and pull rod and mains down to inspect for contamination and crank damage. If you did spin a bearing it probably sent metal through the other bearings and they will all need to be replaced. I have seen rod bearings spin and the crank still be salvageable with some emery cloth to clean up the journal.

As far as making it a higher horse power that generally means you have to change components ie: turbo, nozzles and head on yours. They also go in and change pump settings. Some pump shop can change your settings to give you more fuel if you do not want to do the hardware changes but this is not recommended as this engine has a real problem of scoring cylinders. I have seen some where the pump was set up so high that it actually melted the piston away to there was just a little nub on the con rod.

As far as speedo cables yes they do break. They get rusted and brittle and can only handle spinning for so many years. Have you found where the break is? They come out of the ratio adapter in the tranny and go up to an adapter on the firewall and than to the speedo head. Should be able to take it to a Dealer and they can make you the cable. Also inspect the cable housing to see if that needs to be replaced.

mains 115 ft-lbs
rods 130ft-lbs
This is a 466 right and not a 360. The 466 rods are off center cut with bolts and 360 are straight cut with studs. The torque on 360 is 80 ft-lbs.
