Engine Size: 3.1
Refrigerant Type: R134A
For a 1998 GM V5 Compressor, I am removing the internal snap ring that holds the shaft seal in place.
I just tried to remove the internal snap ring using my snap ring pliers...but my pliers are too short and a bit too bulky..to get into the
bottom of the shaft seal. The shaft seal snap ring looks like a fairly heavy duty snap ring...with size of holes around .070-.080"??
I read in Chick's post that you can also use an awl to remove.
I am looking for snap ring pliers that can compress/remove this snap ring. I am looking for a decent tool...though I wont be doing
this much....so, dont want to spend a lot of money. I know there are many options with snap ring pliers (ie. tip size, fixed/interchangeable tips,
internal/external pliers, etc). I can see that Mastercool offers snap ring pliers...any other recommendations for a decent value pair of
internal snap ring pliers ?

Most auto parts stores will carry a nice snap ring plier. Lowe's and Sears should also have it in their auto tool section. Mastercool offers them but are special order items.
Thx, I was looking for some specific recommendations...I have a pair of snap ring pliers but my pliers are too short and a bit too bulky..to get into the
bottom of the shaft seal. Any other recommendations for a decent value pair of internal snap ring pliers ?
This was some time ago, found a nice pair Made in the USA at my Tru-Value store, Master Mechanic brand, 8" long. Has a thumb screw on it so you can change it from internal to external type snap rings.
Can't be that old, says to wear safety goggles on the handle. But everything you buy today says to wear safety glasses. My son made fun of my old safety goggles, so he bought me a new pair, it said to wear safety goggles when putting these on.
Haven't check lately at Tru-value to see if they still sell them, probably made in China with a plastic handle on it that can cause cancer in rats in California.
I use an awl to remove and standard snap ring pliers to install- much easier and faster- To install, all you have to do is compress snap ring- get it in the bore then press it in with the proper sized socket- or other round pipe- you don't need to reach all the way down in there with snap ring pliers- The awl will most generally ruin the old snap ring- but I install new one anyway..
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 to buy a lot of Truarc snap rings, so if I ever needed a pair of pliers, would get them for free for personal use. Never got one for AC work, so had to pay cold hard cash for that, that hurt.
Needle nose snap ring pliers have always worked the best for me. I have a few different sizes for the different depths.
Thx for replies...
These type of snap ring pliers wont work
Craftsman Professional Retaining Ring Pliers, Internal/External ($24.99)
Craftsman Professional Snap Ring Pliers
Napa Part Number: SER 3150 (I think these are made by KD Tools)
Napa snap ring pliers
As the head of the plier is too large to fit into the shaft seal area...went by my local NAPA
store and tested SER 3150...did not work ..too short and bulky...
Craftsman Professional appear to be similar design..so pretty sure these would not work either...
There are a number of low quality snap ring pliers available..
interchangeable tips...these will not work either...too bulky
and light duty...a number of places sell this same basic low quality snap ring plier
Napa low quality pliers
Harbor Freight low quality pliers
(Harbor Freight often has them on sale for $2.99)
I bought this one
Craftsman Qtr-TurnÃÂ® Convertible Retaining Ring Pliers ($12.99) - Part Number on tool 47384
Notice the narrow tip of the Craftsman Qtr-TurnÃÂ® Convertible Retaining Ring Pliers ($12.99)
...i used these pliers to remove the snap ring...
the Craftsman Qtr-TurnÃÂ® Convertible Retaining Ring Pliers I used had ($12.99) had .070" tips...
which is nice as the snap ring hole on the factory ring appears to be approx .080-.082"..
(The factory snap ring is just under 1 3/4" in diameter and the ring holes are approx .080"-082")
so I .070" tip helps...I am sure a .049" tip would slip a bit...but if the plier was good quality..
it might be ok...
I checked online and there are a number of other good snap ring pliers...
I really liked these Knipex snap ring pliers...
There are many companies that make good quality snap ring pliers...NAPA
seems to have many snap ring pliers...I think a pair like this
Napa pliers (are these KD Tools?)
would also work...tips are .070"..and seem to have a narrow nose...
I just rip them out like GM Tech does. Install the same way.
I usually replace most snap rings with a Spirolox ring anyway, then all you ever need is an awl...

Like I said before, I just use the Mastercool snap ring pliers and have no issues. I have many sets and just grab what works for each compressor.
MAC or SNAP ON, i use MAC great tool,precision made no slip offs.
