Tools for pressing on coil and pulley on V5 compressor

govan22 on Sun June 20, 2010 1:23 PM User is offline

Year: 1998
Make: Buick
Model: Century
Engine Size: 3.1
Refrigerant Type: R134A

I replaced the case (belly) o-rings and shaft seal on my GM V5 compressor. During disassembly, I used the Mastercool tool to remove the clutch plate. I removed the compressor
pulley and the coil using a couple of large screwdrivers...and slowly pried...Now, I am going to reinstall and the coil and pullley. From reading a bit...I can see there is a tool for
installing the pressing the coil back on...and there is another tool for pressing/installing the pulley...

Is it possible to install the coil and/or pulley without the special tools ?...Could I use a wooden/brass hammer and tap the coil on...or maybe even a brass/wooden hammer
and a small punch..and lightly tap coil or pulley...or even some other method to install the coil and/or pulley?

If this is not advised...does anyone have any recommendations on inexpensive coil/pulley installer tools? I would not want to spend too much...and ideally would like to
be able to get the tools from a local supplier (like NAPA, Sears etc.).

I use an old coil i had laying around and set that on the good coil and tap it down in place,then the pulley tap that carefully and evenly till you can get the clip on.

Yeah, the old coil method works great- never had a problem-- or you can use a punch on the ID of the coil- and keep tapping in a circular pattern--

The pukkey- I use a pulley tool-- or you can just use a large pipe or big socket- to tap it down= as long as you are tapping on the ID of the bearing- the same race that is being pressed on.....

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

I used an old coil to tap on the coil - agree that is a great way..coil went on pretty easy...thx for tip.

Put on the pulley and used a 32mm deep socket...tapped down on the bearing race..worked pretty good
until I got right near the bottom (socket was just slightly too small to go over the shaft), used a punch
and tapped the pully down for last 1/4" or so

One thing that I realized is that the coil has to tapped down tight..right against the compressor collar?...
first time I put the coil on I guess I did not have it tapped down tight (was a slight? gap)...this made
putting the pulley on a bit harder...and could not get the pulley down far enough to put on the retaining
clip...after getting the coil flush with compressor...pulley was able to be tapped down last 1/4" or so..
and clip went on pretty easy
