I have a Nippondenso 10P15C compressor and I just replaced the shaft seal.
I was wondering if anyone knows how tight the five casing bolts need to be?
If it were not for ACkits.com I would have never found the shaft seal.
Thank you,
Nathan
NIPPONDENSO 10-CYLINDER SHAFT SEAL
NOTE: Check compressor refrigerant oil level when replacing seals. See the A/C COMPRESSOR OIL CHECKING article in this section.
Removal
Hold clutch hub stationary and remove center nut. Screw remover into center of hub. Turn center bolt to remove pressure plate.
Remove shims from shaft. Remove snap ring from inside of pulley. Tap pulley off of shaft with plastic mallet. Be careful not to distort pulley while removing.
Disconnect clutch coil wires from compressor housing. Remove snap ring inside coil and lift coil off compressor. Pry dust seal out from around compressor shaft (if equipped).
Place shaft key remover on shaft and turn to remove key. Remove drain plug (if equipped). Remove bolts holding service valves to body of compressor and remove valves. Discard "O" rings. Drain oil out of compressor.
Remove
6 through bolts from front head of compressor and discard washers. Tap head loose from compressor, being careful not to scratch sealing surfaces. Remove snap ring (if equipped) from front housing. Press seal plate out. Remove seal from shaft.
Installation
Lubricate shaft seal with clean refrigerant oil. Place on compressor shaft. Lubricate seal plate (and "O" ring, if equipped) and install in front housing. Install snap ring (if equipped).
Place front housing on compressor body. Using new washers, install through bolts. Tighten bolts evenly and alternately to 18 ft. lbs. (24 N.m). Install shaft key with installer and plastic mallet. Insert dust seal into front of compressor.
Install drain plug using new gasket. Add correct amount of refrigerant oil to compressor. If service valves were removed, coat new "O" rings with refrigerant oil and install service valves.
Place clutch coil on compressor and install snap ring. Install shims on shaft to adjust clearance between pressure plate and rotor to .016-.028" (.41-.71 mm). Tighten shaft retaining nut to 12 ft. lbs. (16 N.m).

Thank you very much!!!
Where did you source that info? I would love to read more.

A program I paid thousands of dollars to have access to.

Thank you!!!
I have a problem.
My compressor has no suction or discharge after installing the shaft seal.
What should I look for inside the compressor to diagnose this problem?
I have not installed the compressor.
Can I apply compressed air (130psi) to the suction port to check for a leak or
will that cause damage?

I prefer nitrogen. If no oil is in the compressor you could use shop air but try to filter it to remove moisture.
-------------------------
I attached the clutch hub and spun the compressor CC while adding 130psi and the compressor still won't suck or blow.
A very small amount of air exited the discharge port. Maybe 5psi. I could seal it with my thumb.
There is no leakage past the shaft seal, or case seals, so something internal is amiss.
Any suggestions as to what could be wrong?
How do I test the dual pressure switch on this system.
I checked for continuity on the poles with the plug removed and got a wide open reading (no resistance).
The system has 90psi in it.
Thanks,
Nathan
