mx13 epa 13 ccv ocv spinner

The early ccv filter modules were non serviceable to include EPA 13 and early EPA 17. Newer engines have a replaceable filter element and the CCV modules must be removed from the engine to replace the filter. The older non filter modules are obsolete and you must install a newer module with a serviceable filter if it fails.

The new replacement modules are indeed on the hard to get list and have just started trickling in for at least 6-10 I have had on B/O for some time.

Your ccv is not spinning as 1000rpm is the default value in Davie. Check power and ground to the module. Spinner motor is likely open/shorted. You need a new module most likely. The new module will have a replaceable filter.

 

Yup. Newer part has a replaceable filter element.

I have never disassembled one. It was always an issue with the motor and that they do not spin, as you already found.

 

Good day, I dont know if this is the correct forum but I'm trying to get some advice on a paccar mx13...
I have an issue with main bearings. The engine spun the mains in december, I had them replaced. Now after a month and a half it spun the mains again. It had new oil and filters. Does anybody have any experience with a similar issue on paccar engines?
Thank you.

 

Block must be replaced. If the bearings spun the block is damaged beyond new bearings.

 

Thank you for your reply, the strange thing is that it only spins the bearing on the 4th journal. All the rest are fine.

 

#4 is the first main to get oil. It’s also the first one to get any trash or debris if anything make it past the filter.

Did your mechanic roll in all new mains with the crankshaft still installed? Just do #4?

End of the day it really doesn’t matter. If they spun it needs a short block minimum.
