Can you greese #4 speedmaster hinge pins with out disassembly? Mine are popping when I raise and lower my drives . I think this is contributing to my drives being lazy also .

I Rebuilt Mine No Grease Fitting Their. If The Pin Is Popping The Helmet Is Probably Worn Also.

whats the rebuild , remove clean and reinstall?

That All Depends On How Worn It Is. Mine Had To Be Heated With A Torch To Get Apart. The Helmet Pin Hole Where Oblong. Sent Then Out To Be Oversized And Bushings Installed. Its Not Easy To Get Apart, The Hindge Pins Have Little Pins That Go In With The Little Set Screws That Hold Them In .

I removed the allen bolts and filled with liquid wrench . One drive is free , the other side will require removing the pin . Tomorrows task .I must create a slide hammer from all thread . All I need is a little movement and I think all will be good .
