A/C Compressor Shaft Seal Replacement

[Jawwad-Arshad-SANDEN-Expert]

These Local Sanden compressors are not famous in market. The imported Japanese one's worked well. IF Sanden Pak wants to help people of Pak they should introduce some new scroll type compressor models.

Bro we have original SANDEN compressor as I told in my detail introduction. We are giving AC system to Pak Suzuki & Honda..

Does your company sell the shaft seal and other bits?

No Bro we are selling complete compressor Assy...

so what do you suggest one to do when the shaft seal goes bad?

Let me know which car you have bro?

i own suzuki swift 86 model gti. Allhumdillah the ac is working great. i am planning to upgrade somethings with its look inshaAllah

Bro we are not advising for any repairing in compressor case because no one knows about its life. I suggest For saving any inconvenience just go for new, save the time and give the best to customer...

i think they want us to replace the entire compressor rather than changing small parts which is a normal practice in rest of the world

If a system is showing very good measurements of sub cooling or superheating and have good running pressure, no noise in the compressor unit but have a shaft seal problem you wont sell the seal? How is that even acceptable? Would you change your car if you broke the windshield on it?

No problem if you cannot supply it - People can buy the seal from elsewhere (e.g. outside of Pakistan). Very easily too.

btw - if your firm is advertising itself as all and mighty for Sanden in Pakistan then please also cater to the small parts supply - I personally have not found even a replacement pigtail wiring harness for your compressors. I believe you would advise to buy a replacement at that time too.

The rest of the world DOES replace that seal. The compressor is only replaced when its truly worn out or damaged, there are proper tests for determining a compressors efficiency.

another similar example is diesel injector nozzles, you determine their working by testing it on a test bench, if faulty the nozzle tips are replaced - The manufacturer does sell the tips and also a complete rebuilt unit - They dont fully rely on just selling rebuilts - there market will quickly close.

This guy is saying that no-one knows the life of their compressors (including themselves I think) - hence the decision not to sell field service parts.

there was one thing i wanted to ask. how can i check the actual cooling of my car. that is the cooling is there in full scale. measure kaisa kru ? i want to see that weather my car is doing or performing its cooling job perfectly. the vent is throwing cold air duh. the pipe i dont know which one is that is icy cold. and i installed a fan but due to lack of space at the front i installed it at the back. infront of engine bay. but i want to check the performance of my ac i hope you are getting what i am trying to say.

test gauges, thermometer on the vent, fresh intake and line temperature too (use an infrared thermometer for this)

The entirety also depends on climate temperature where the vehicle is being tested.

i know the cooling is awesome but still there remains a doubt that weather the ac is performing its cooling at it best.. can you tell me what is fresh intake and line ??

to fully test the A/C - measure high and low pressure while reading the thermometer placed on evaporator vent, also measure the temperature of the evaporator air intake. So you know your delta.

Thats a start.

Surprised to see that in 3 years nobody responded to your post. It seems in Pakistan we don't have many keen car enthusiasts who know what they are driving, inside out. Hence ustaad-shagird nexus is happy and flourishing like mushrooms in a jungle.
