I tried to grease bogies today and 3 of the 4 pins would not flow new grease out the pin ends. I grease them every year or at 1000 mi. These were greased last September 2013. I only put 1056 miles on it since last greased. They have the double zerts on each pin and have always taken grease easily. Any thoughts what is going on?

Jack the bogies up to take the load off the axles. Get a shovel and put it under the mid bogy and have someone move the tire up and down while you add grease, do the rest. The person that sold us the first coach told us about doing it this way and it worked for us. It unloads the bogy pins so they will take grease.

JR and Dan I forgot to mention the unloading and lifting with shovel. I did this today and in the past the pins would take grease even when the wheels were not moved up and down. I have not done any work on the bogies or tightened the pins that is what is puzzling.

Did you check the check ball in the zerk fitting using a small pick or similar tool? Sometimes they corrode just the slightest bit that you won't even see (because it's between the ball and the fitting body) and the ball sticks and stops the flow.

Is it the bogie pins or just the grease fittings that will not take grease? With that many failing to take grease, I'll bet you have some stuck grease fittings.

Thanks for replys.
All zerts took maybe one half to 3 squeezes and then the squeezing became VERY, VERY stiff and some took maybe 2 to 5 more squeezes but it really didn't feel like grease was moving and no grease showing at ends except for one. This gun uses a one hand squeeze handle so I put a pipe cheater on it and used 2 hands and nothing broke loose. I removed 2 of the double zert tubes and the gun easily pumped grease thru them. I am really surprised by the lack of flow. I always pumped a lot thru and out the ends to put as much new grease in pins as what seemed good preventive maintenance. Grease is a lot cheaper than new pins. I will drive it to top off tanks and try to grease pins before I park it for winter. It may be spring or never before the problem is resolved.

Larry,
I had one fitting like that on My John Deere last winter. It was on the hydrostatic drive pedals and was binding badly. I pumped the fitting up with as much pressure as I could and then went out and plowed snow. The grease under pressure did not leak back through check ball in the fitting but did get distributed through the correct area. That night I did the same greasing thing again and two days later plowed more snow. After that second plowing I tried to grease it a third time it took grease normally.
I have a couple more fittings on the lower pivots of front loader bucket that occasionally refuse to take grease. They are subject to a lot water, ice, snow, dirt, etc. I do the same greasing thing with them. I pump them up with as much pressure as possible and exercise the bucket multiple times until it frees up again. After that they take grease normally.
I think that you are doing the right thing. Grease it and drive it. Then grease it again.
