Grease Zerk

[GreatWhite]

Noticed while greasing my newly acquired 96 Conquest today that it is missing a few grease zerks. Tried screwing a new one in but it doesn't seem to want to go. Are the zerks threaded or are they a push in type? Didn't look like there were threads inside the hole. Hard to tell though.

Are greasing these machines a real pain. Seemed like there were a few that I couldn't get the grease gun on. Any advice?

did the old grease zerks fall out or get broken off? If they are broken off, you will have to use an easy out to get them out. good luck!

You'll need a 90 Deg fitting for the front two

Update: They do indeed use a drive in grease zerk. Tapped them in with a hammer and done. Just make sure you use a nut or something similar to protect the zerk from any damage from the hammer.

These macines are a bit of a pain to grease, by that I mean that it's impossible to get at some of the grease zirks. You may want to run remote lines to some of the grease points in the future, like the ones behind the battery or the ones on the trans side of the Idler Shafts.
And yes, they are interference fit zirks. If you run remote lines, you can tap the Bearing covers and thread fittings into them, but I would recomend brazing the fitting as well for a stronger conection.

Any zerk fitting you want on page 2174 Mc Master online catalogue.

Thanks for the info guys. How often do you grease? The fellow I purchased the machine from said grease every time you use it. Makes sense to me. Pushes out any dirt/water and keeps everything lubricated. Is there any downside to greasing to often? I believe the manual says to grease the inner bearings every 10hrs and the outer every 100hrs because they are packed with grease at the factory. Do you guys grease the zerks in behind the tires as often as the inner ones?

I don't think you can overgrease, any extra will find it's way out.
My experience is that the outer bearings need grease more often than the inner. Maybe not everytime I go out, but close to it. Inner bearings last up to 5 times longer than outers

It is possible to overgrease. 30-60% grease fill is ideal. If you have ever pulled apart a bearing and the grease pours out like oil, it is because it was overfilled. When filled full, the grease has no where to go as the bearing turns and it churns it and breaks it down. This happens the worst on fast spinning shafts. I think the benifits of making sure the water is purged from the outside bearings override the grease breakdown issue. But something like the bearings on the torque converter output shaft(if it has a fitting????) I would not grease every time.

LOL, OK I retract my statement. It IS possible to overgrease a brearing, however, on a Conquest, there are no greasable bearings that can be overgreased. They are all on the slow spinning side, and any extra grease ooozes out pretty easily (unless you have upgraded to HDI outer axle bearings, overgreasing those can push the outer shield off the bearing).

can you use a electric grease gun to do this or must you use the hand pump grease gun?
Thanks
