Any info on CV's with grease zerks!!!! (video)

[sl1111]

Does anyone here know if these are DIY, or what it takes to build them?

Or, can I buy CV's already done and where?

Looks like a very cool idea. I wonder how it affects your current axle length, if at all?

On Jeff Quinn's Class 1 we added Zerk Fittings the CV Joint. When we stopped for gas or a tire change we would add a pump or three of grease into the CV Joint. Call Mckenzie's and see if they can help you out.

That Is An Awsome Invention I Wonder If You Can Make Your Own For Less Money? Im Definatly Going To Get These One Day!

I want that.

with all good also comes bad. The problem arises when something hits one of the zerks and knocks it off, the cv grease which is about 150 degrees hotter all comes out of the newly formed hole, dirt, mud, and water all take it's place. Needless to say you end up changing out a cv in the desert, ruining your high dollar custom driving suit and a chance for the win, and 10 min trying to put out the brush fire the grease started. I know, you are going to say it will almost never happen, but it does. Make sure they are protected, and you don't half ass the install with cheap parts.

make a flange with a counterbore so it cant be broken off...problem solved.

[JAM 1600]

After greasing remove plug and then install an allen plug ! Problem solved again. But as it was stated earlier with good comes bad, now that you do not have to remove cv's to grease you will not be inspecting cv's as much either and when the star or cage fails you have just bought an axle along with a cv so what is your time worth ?

[partybarge_pilot]

Flush mount zerks that take the needle fitting. Also, if your drive flange are thick enough, you could drill and tap holes in the and not need the plates.

[Jack]

Make the plate a little thicker and counter sink the zerk.

I expect that if you need to add grease during a race you have a damaged boot or there is something else going wrong (creating heat) to require grease mid race. As far as in the shop... Take the CV apart, clean it, inspect it and grease by hand. If everything was done right in prep and a boot hasn't torn you don't need a zerk on your CV.

I just called IMCO and spoke to Greg. He addressed a few issues......

The Zerk whole is machined into the flange, so it can be removed and replaced with a 90 degree fitting or swivel fitting. This will allow greasing when mounted inside the trailing arm flange if your outer CV is recessed into the trailing arm.

They also come with a set screw that plugs the grease hole. You can remove the Zerk after greasing and place the set screw in the hole if you don't want the fitting left in place.

It is a standard grease Zerk so any standard pitch thread fitting should fit.

The flange's are 1\2 inch thick. He said they did not have to change axles and have had no customers needing to change so far. I guess the jury is still out on that one. From what he said, your axle ends are in the same location relative to the output and axle cups, just the star is slid a little more inward on the spline. I would assume it would however change the angle a little.

Contact Greg or David at IMCO for more info.....

I am not wanting these to just add grease and never take apart my CV's again. Rather, I have always liked to assemble my CV's and axles dry. Bolt them up with thread-locker and safety wire, and then add the grease with a needle. The needle is time consuming and often break. I would use 3 or 4 needles on a set. This just makes it possible to eliminate the needle portion and also add a few pumps once in a while.

We drill all our cv's for zert fittings. just as they mentioned above, we usually have someone do a couple pumps at fuel stops. we had porter do two sets for us.

Well put.

We will be doing a set of the new Gear One grease able 934 CV's on our prerunner.(LS7/Albins) We will see how the hold up and the ease of maintenance. We are told that this is the first set out from them. Time will tell.

[wheezy]

Man, I got a good laugh thinking about my first time building / greasing / installing CVs. What a goopy gewey greasy mess that was.

+1 on the dry install, loctite, safteywire THEN grease method. No loose CV bolts due to grease!

[Steve0]

The zerks looks like a good idea if protected. It looked like they where pumping multi-purpose bearing grease into thos things, that not a good idea.

post how they hold up we run 934 ls6/albins as well, would like to know what the turn out is on those are, and are you running duel cv boots on your cvs or a single boot?

I did buy there grease caddy for my 934's and it works awesome. I used it this last weekend for the first time. I don't think I have ever been able to get that much grease in them that clean.

[goofballracer]

would it be a total pain to drill and tap a hole in the cv itself where there is no parts that touch the spot

How many miles did u put on them that weekend? Did u pull them apart after and look at them? Any info would be great thanks

They make a tool that is used to pack the CV's during prep. This is what I was talking about. It worked awesome. I am trying a new grease for the vegas to reno prerun that I will be reporting on.

What kind of grease are you going to be running for the race and what were u running before if you don't mind me asking

Is that the tool in the McKenzies catalog?

[D-rek]

I got the tool that is listed on the Imco website listed on the first page. It is two plates with a shaft the same size as the axle spline and a zerk fitting. The grease I have been using is the standard Bel Ray/Neo mix which works okay but I am sick of spending $200 in grease every time I prep CV's. The stuff we are trying is a Moly based industrial grease that seems to have very similar chemical properties as the Neo and Belray mix. I will post results after this weekend.

I have a tool to pack CVs.Like someone said above. I use 1 tube of Valvoline HD w/moly (cheep) and i do all 4 with a tube. 44 pumps of a H/F air greese gun(9.99 on sale only way to go) and they are full . Shoot a little in the drive flange and stub axle and red lock-tight at 50 lbs. torque. Have never had a failed CV(16years). Knock on wood !! A little baby powder on the out side of the boots good to go.
On an other note whats the maximum angle you use on you cv/axles ?
