A C magnetic clutch removal

[dphatch]

Having difficulty removing ac clutch/pully to replace bad pully bearing .  Have removed bolt securing the clutch to pully but can not remove it.  AC is functional and is switched off- negative battery terminal removed. Am confused as to why, if the clutch will engage and disengage, when actuated why it will not come off the ac compressor shaft ? Any suggestions would be appreciated.

That is because it is pressed on.  You will need the correct pully puller to get it off, and another tool to get it back on.

Thanks for responding. All the YouTube videos, while limited, I watched of guy's  removing the clutch from Denso units on Porsches showed it coming right off,  almost falling off as a matter of fact.  Being pressed on  would explain why nothing I tried would budge it. Local Autozone did not have anything in the way removal tools that would fit the threads of the clutch but found one set  on Amazon that claims to work on Denso units. Will order one up and  see.

 

While I've got you, I found 2  specs for bearing …  30  x 52 x 20  and 35 x 52 x 20. Can you confirm which is correct ?

Could be either one, we wait till it's apart and see what is in there.

As an update, could not source the tool  to remove the clutch so replaced compressor that included new clutch and pully assembly.  Given the price of just the  replacement clutch/pully assembly, the cost for a new compressor  ( $325 tax and shipping included for an identical DENSO replacement from the OEM manufacturer ) and the fact that the existing compressor was  12 yrs old , it did not make sense to continue the mess with replacing the clutch on a 12 yr old compressor.
