Zerk fitting replacement?

wrench and may be a little hard sometimes,,, if so get vice grips.

Harbor Freight sells a assortment of zerk fittings.

 

Is it just pumping the grease out the connection or does the gun pressure up and seize? Easiest thing to do is to remove the fitting and clean out whatever is behind it and install new fitting. If that doesn't work you could try some heat depending on what it is that won't take grease.

 

What are you greasing making the gun seize? King pins? Front spring pins?

 

Yeah..It happens- About a month ago I re-zerked #3 U-Joint- actually the Zerk Broke in 2. Used a Pick to get the broken piece outta the joint- It Happens.

 

I would keep the heat away from any steering or axle parts. Cams would probably be fine as long as you don't torch any airlines or wiring near them (or melt the bushings).

 

Can try and turn the steering wheel back and forth and try to grease it at different angles. Could try and chock wheels and try to grease the cam with brakes released too.

This is one of the reasons I don't care for extended service intervals. Grease hardens over time and with exposure to heat, dust etc. Can cause things not to take grease if the grease gets too hard.
