sir dieseldude, good day, I had my pajero serviced at central diesel clinic a few years back and its still doing great, pag may question sa pajero gen 2.5 calibration parati kong suggest to go to your shop, sip sip ba? I was wondering if you could shed some light sa problems ng 4m40 injection pump namin, usually we experience hard starting sa umaga lang then papalya siya, then restart 3 to 4 times uli ganun parin, but pag uminit na wala na kaming problems, no balck smoke, power is still very good and fuel economy is still normal, naglalaro kasi sa mind ng owners bakit calibration agad ang solution despite pag uminit siya ok naman na, can you please help shed some light kung aling parts ang nagcacause ng hardstaring and namamatayan sa umaga? and what can we do to prevent this? or is it just normal wear and tear. This is a common problem on 4M40 injection pumps. Failure is in the drive shaft, drive shaft bushings, and oil seal, allowing air to enter the pump when engine is shut down for a few hours. Pump has to be repaired and calibrated, no other way.

question 2 sir, meron ba kinalaman ang calibration sa shifting ng auto tranny? Yes.

may isang member (larshell) kasi na may delayed shifting na nangayari after niya pacalibrate. can you confirm this sir? post ko yung reply niyo sir sa gen 2.5 threads, or even better baka pwede niyo dalawin yung thread namin, thank you sir, and more customers to central diesel clinic, Mounted on top of the injection pump's control lever is a throttle potentiometer. This is a black 3 wire variable resistor which controls transmission shift point. Electronic adjustment is performed while the injection pump is on the test stand.


Bye, Godbless,


Dieseldude
