parts list and tools required for replacing compressor shaft seal on a V5

govan22 on Wed May 26, 2010 4:24 AM User is offline

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

I am going to replace the compressor shaft seal in my 1998 Buick Century.
The compressor is the Delphi V5. The compressor ran pretty good (quiet)
and had cool air for a number of years. But, it started losing refrigerant last year.
I put a bit of dye in the refrig and I am pretty sure the compressor front shaft seal
is leaking. I took the compressor out. It is very easy and quick to remove on 1998 Buick Century.

I noticed there was also a bit of oil leaking near one of the front bolts (6 front
bolts that are behind the pulley). Not sure if there are o-rings behind these 6 front bolts?
I thought it might be a good idea to replace these o-rings.

I also thought it might be a good idea to replace the body casing o-rings (called 'belly o-rings'
or body o-rings, I think). I thought it might be better to just change these body/belly o-rings
while the compressor was out and hopefully avoid any future leaks.

I have done some reading on these forums (great info). I read Chick's great
thread "Changing GM R4-V5-HR-HD-HT and DA6 compressor front shaft seals".
I would like to try and save this V5 compressor, with new seal/o-rings as I
think it still runs good.



It appears I need the following:


new V5 shaft seal
---------------
SHAFT SEAL KIT V5 HR6 HT6 DOUBLE LIP SEAL (ackits part # 21-34659 )


shaft seal removal
------------------
GM Ceramic Seal Set Removal - Installer (ackits part 90486)
GM Seal Protector (ackits part # 90484)


misc parts
----------
4 ounces of PAG 125
Nylog (Blue) Gasket Thread Sealant (ackits part # RT201B)
Accumulator - Drier (ackits part # 37-23404)



It does not appear that ackits supplies just a clutch plate remover/installer
tool for the V5. I can see kits that include a tool for the V5. But, I
think I am likely going to try and borrow a Clutch Plate Remover Kit from local autostore.



Questions
============
1. Does that parts list/part #'s look correct for what I need from ackits for a V5 shaft seal replacement?
2. Does ackits sell a separate clutch plate remover/installer tool for the V5 (that is not part of a kit)?
3. Are there o-rings behind the 6 front bolts on the V5?
3a. If yes, what is the ackits part # or kit # for these 6 front o-rings (on the V5)?
4. what is the ackits part # or kit # for the V5 body/belly o-rings?
5. Is there any way to tell if the V5 Compressor that I have is rebuilt?
My V5 has a sticker that states 'delphi-5145', Part 1135145, Code 060581938C.
6. Does ackits sell PAG 125 oil (in 2-4 ounce cans) ?

Any other advice/tips are appreciated.

3. Are there o-rings behind the 6 front bolts on the V5?
No- they are sealed by the heads of the bolts on a soft aluminum sealed surface- bolt torques are 12-14 Nm-- oldermodels had washers behind them-- newer ones do not.

3a. If yes, what is the ackits part # or kit # for these 6 front o-rings (on the V5)?
N/A


5. Is there any way to tell if the V5 Compressor that I have is rebuilt?
Yes- look for a painted pump-- rebuilders generally paint them-- but yours is OEM.


My V5 has a sticker that states 'delphi-5145', Part 1135145 Code 060581938C.

based on your label code- your compressor was built on June 5th, 1998 at 19:38 (7:38pm) on production line C-- so compressors are in general two weeks older than the cars they go on-- so your 1998 Century was probably built in June of 1998-- check driver's door date stamp to be sure....so your compressor that has a Blue background is the OEM compressor--- if it had an orange background it would be a replacement compressor (service unit supplied by Delphi)

-------------------------
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 looked up ackits #21-24683 (Gasket Kit -GM Noise Buster V5). I will add #21-24683 to my order. It looks like this kit #21-24683 includes the V5 body/belly o-rings plus a few other o-rings/gaskets.
Any idea what other o-rings/gaskets are included in ackits #21-24683 ? Gmtech, thx for info on front bolts. When I pulled the V5 compressor I had left it sitting vertically on the ground (with pulley
on ground)...that was when I noticed a bit of oil around one of the front bolts. I looked at the front bolts and dont see a washer..though the bolts dont appear to be sitting entirely flush either.
.
Regarding the V5's body/belly o-rings..I thought it would be a good idea to replace these while compressor is out...anyone have any tips/advice for replacing the
V5's body/belly o-rings ? After replacing the V5's body/belly o-rings what is recommended way to bench test for leaks?

When replacing the accumulator, I would like to replace the o-rings on the fittings. I would also like to replace the steel/rubber washers that sit in the compressor where the lines attach.
Any idea what ackits # includes the o-rings on the accumulator fittings and the compressor steel/rubber washers?

I am also thinking of replacing the Orifice Tube. I read this thread http://www.autoacforum.com/messageview.cfm?catid=2.&threadid=19680
It looks like the OT is located near the power brake vacuum booster. It appears GM started using a newer style OT in 1999?
My Buick is a 1998, so I think I have the older style OT? Any idea what is correct ackits # for a 1998 Buick Century OT ?
Do I need a tool to remove the OT or can i remove with very thin needle nose pliers (have a several tiny pairs of very long needle nose pliers).

No need to even look at the OT--- not worth the effort to remove the brake module----

I ended up ordering an OT...I think I will likely try and replace it...though not 100% sure..if too tough may not put it in.
I also ordered the 'CP3010 - 1989-2005 General Motors System O-ring Kit' and the 'CP3016 - 2005 & Prior - GM Sealing Washer Assortment'.
These kits should have all the o-rings/washers that I need (and likely some extras).
.
I ordered the '21-24683 - GM Noise Buster V5 -Gasket Kit'..this kit appears to have V5 body casing/belly o-rings.

I am thinking about doing the same repair on my 2000 Grand Am, V6 3400. What was you total for the order? Trying to compare to replacing with a reman unit. Thanks

govan22 on Thu May 27, 2010 12:45 AM User is offline

My order was $103 plus shipping...shipping was a $25 to NY...here the parts with the prices from ackits

SHAFT SEAL KIT V5 HR6 HT6 DOUBLE LIP SEAL (ackits part # 21-34659 ) $9.68
GM Ceramic Seal Set Removal - Installer (ackits part 90486) $20.88
GM Seal Protector (ackits part # 90484) $5.12
P125-8TSI - DEC PAG - Blue (8 Ounce Bottle) $8.94
Nylog (Blue) Gasket Thread Sealant (ackits part # RT201B) - $9.49
Accumulator - Drier (ackits part # 37-23404) - Price: $19.42
1989-2005 General Motors System O-ring Kit (ackits # CP3010) $11.22
2005 & Prior - GM Sealing Washer Assortment (ackits # CP3016) $10.51
White Orifice Tube (ackits part # 31-50001 ) $1.27
GM Noise Buster V5 - Gasket Kit (ackits # 21-24683) $7.43

It was a little more than I wanted to spend...but have to say support was very good...Tim answered a number of questions for me via email
and Adam called me to let me know about shipping the order...

A reman'd V5 from ackits is $197 for my car...plus I'd still need about $60 more in parts...accumulator ($19.42), PAG125 oil ($8.94), Nylog Sealant ($9.49)..
GM o-ring kit ($11.22), GM Washer kit ($10.51), OT ($1.27),...but, I am pretty sure my V5 compressor is still good and hopefully just needs to be resealed...
plus I kinda like trying to fix it...

I've probably re-sealed 50 or more V-5s- actually are easier than the H-6s IMO. You'll need to separate the cylinder from the front and rear heads- I use a slight twisting motion and a good wide vice...
