This simple ram rebuild bit us in the ass.
We're repacking all the rams on our 446b and left the extendahoe ram rill last. One pin came out fairly easy but the second pin on the top gave us hell all day.
Heat, oil, cool, hammer repeat.
Then we broke out the 100 ton ram and welded on a press frame.
Got it to 80 tons and got the heat on it and still not a budge. Bent our puller blocks and blew our welds off.
We gave in and just torched the pin and got the ram out and figured press one side at a time.
With the ram on a single side and 80 tons and heat not a budge!
So I split the bushings with the torch and gave it a go again and still nothing.
Broke down and cut the whole bushings out.
Gonna have to machine up a new pin and new weld in bushings.
Anyone else experience this? It's only around a inch in diameter to.
