Hi,
I have a 98 24v that I has a spun bearing.
Is it possible to pull the bottom end apart without removing the engine.

I installed a BD exhaust brake and was testing it out at about 50 mph with no load in truck and my engine spun a bearing , any body heard of this before?

Thanks,
Rich

 

that suxs bro sorry to hear! Good luck Someone helps this guy !!

 

if you spun a bearing , the crank will have to come out , so yes the engine must be removed.

 

I don't think the pan will come off with the engine in the chassis anyway.

 

How do you know it spun a bearing? If in fact it did i am sure the crank and rod will need work or replacement. So if the spun bearing is the case you might as well pull the motor. And no spun bearings are not common.

 

To my knowledge, there is virtually no way to accurately diagnose a spun bearing unless the bearing, cap and seating areas are adequately inspected which obviously means a complete disassembly.

I have a never heard of a 5.9 CTD spinning a main or rod bearing.....from my experience, I would have to agree with nitrousn and say that it is definitely NOT a normal occurance.

How did you come to the conclusion that a bottom end bearing has spun?....and what does using an exhaust brake have to do with spinning a bearing? I'm not trying to give you a hard time - I'm just very curious.

 

Ya tell us more. You got my attention now. Did a Cummins shop tell you this?

 

i constantly use my exhaust brake, empty or loaded, high speed or slow. an exhaust brake will not cause a spun bearing.

if you are hearing a horrible noise, it may be a valve. the 2nd gen trucks need upgraded,60 lb, exhaust springs so the valves stay shut and not strike the piston. unless you changed the springs, there's your problem. it is very unlikely you spun a bearing, these bottom ends are bulletproof, most sled pullers dont even touch the bottom, and they do WAY more abusive stuff than an e-brake can dish out.
good luck.

 

I thought it was only the 12v that needed the upgraded springs?

 

i could be wrong, ask my wife, it happens all of the time.

copied from BD's website tonight. shows '98 needing 60# springs. I still could be wrong.

 

The pan can be removed on 4x4 i dont know about a 2 wheel I searously doubt a spun bearing.
By the way why do you use the brake all the time? just curious

98 was when they had both the 12v and 24v in it. I know for a fact that the 12v's need the upgraded one's and I'm about 99.9% sure the 24v's don't.

 

I use my EB ALL the time - empty or loaded.....there really isn't much need for service brakes when using the EB empty.

98.5 - 02 24v's do not require heavier exhaust valve springs as the OEM's are adequate.

 

see, I told you I was wrong. thanks boys
