tips for removing a sticky V5 compressor shaft seal

govan22 on Tue June 08, 2010 8:10 PM User is offline

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

I am replacing my V5's compressor shaft seal. I have the Mastercool Seal Removal Tool.
The Mastercool Seal Removal Tool goes into the top of the seal pocket area...I can get
the Seal Removal Tool fairly tight in this seal pocket area...but the tool will not grab the seal
and eventually spins...

Note, I did tap down on the seal to help get the snap ring out...probably should not have
done that...

Any ideas/tips for removing a V5 compressor shaft seal that is kinda stuck...or hard to
remove ?

Must be a bad tool-- I have a seal puller that I've used on a couple of thousand shaft seals- never had to worry- just get it in good and tight- the use a slight twisting motion and it pops right out- Does your tool have the knurled edge on the gripping surface?


I don't know the source of my tool- probably hand made by a local tool shop.

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......

You probably twisted it when you hit it now it's wedged in their,try a pick type tool to get in there and hook it,

I've pressurized the compressor on the bench before- to blow them out- but can be dangerous..

I also once drilled a hole in either side of (180 deg apart) one- and used drywall screws to pull one out

I think the problem is that I tapped down on the seal when trying to remove the oring.
.
One of the things I noted about the new Mastercool Seal removal tool was that it was very difficult to turn the
inside portion of the tool...I placed the seal removal tool into the seal and then tried to turn the top piece of
the tool (which expands the bottom piece outwards)...I was having a real hard time trying to turn the
tool...I was having to press the tool in..while trying to turn... turning the inside portion of the tool expands the
tool...as the tool expands it fits up tight against the seal inside lip..

Anyway, what I eventually did was put a bit of oil on the tool thread and then proceeded to work the threads
in a bit...for 2-3 minutes..so that I could eventually turn the top piece of the seal removal tool by hand...and
the bottom piece would expand...

After doing this with the tool...I tried a seal removal tool on a few practice V5 compressors and the Mastercool seal tool
worked fine to remove the shaft seal on these compressors...now I understand how the seal removal tool works on a V5 compressor


I will post a few pics that might help someone that is also doing this for the first time...

Yep i always add a few drops of oil to the threads and inside shaft of the tool helps it turn easier.
