Cat D4GXL blade info

If you haven’t already figured it out, post some pictures would be helpful.

"I'd say to new for this crew"

I'll try to put up some pictures....................I thought surely somebody on here would have knowledge on this. I have a service manual, but I can't find anything in it about removing the two main pins on the blade. They look like a press fit to me.........[attachment=57333]2302-092218.jpg[/attachment][attachment=57334]2302-092232.jpg[/attachment][attachment=57332]2302-092113.jpg[/attachment][attachment=57331]2302-092157.jpg[/attachment]

That looks like the type where you remove those two bolts and the pin keeper plate, then the pin "just slides out". In practice, you probably have to pound it out from the inside, or, if Cat were very helpful : ), you could just drive it all the way through to the inside and it would drop on to the ground. That keeper plate might be reversible and if so, turn it around when you fit the new pins so that the pin retention is solid. Any movement and it'll flog out rapidly. It also looks like the bores for the pins might be worn - if so, you'll need to get someone to come out, bush the holes or even build them back up to std and then line-bore and ream them to size for new pins. That's at least what it all looks like from my armchair.

The body of the machine won't let the pin go thru to the inside. It also looks like the roller frame might keep it from coming all the way out to the outside. The pin may look loose in the picture, but I've never seen any movement even when the machine is in motion. Both pins have a threaded hole in the center of them. I wonder what that's for. Hard to believe the service manual doesn't make any mention about it. Would there be a separate manual for the blade?
