I have a Cat 941 and the bushings for the tilt links and bucket are shot/gone. We are acquiring another 941 with a good bushings all around. We are going to swap the boom and I was looking at the pins, they have threaded holes where the grease fittings are. My question is, does anyone know what size bolt would fit that hole? and do I need a special puller to remove those pins? any help would be great. Thanks Grason Here is the best picture I have at the moment. I can get some close up shots if need be.
If you look at my Thread Using a bit of Muscal you will see me stripping out a frame or 2 on CAT shovels, the thread is ANF and a hollow ram helps some, if you needed the exact size use a vernier measure or ask and I will tell you, after the bucket is removed crib up the frame of the rad top area to remove the pins easily.
I saw your pics, hopefully I can make a puller of some sort to yank them out. My only other task is trying to determine what size bolt I need to fit inside the pin.
You often find Cat use UNS threads in those pulling holes. Makes it a little harder when you just need to grab a spare UNF bolt
You will need a 1 1/4-12 rod to pull those pins.
Roger, I appreciate the info guys.
You might also need an 1" x 14 ANF rod to pull a few plus if they are stuck a 50 ton cylinder to stuff into them.
I made some good progress this past Saturday and thought id share some more pictures.
