master link

[Catdaddi]

Can you install a master link like a dozer (gator) on an excavator?

 

[mitch504]

Yes

Its a lot of stress on them, the wider the pad the worse it is.

That's why excavators have pressed-pin master links rather than a croc joint. The wider the shoe, the worse the job of trying to keep the master link bolts tight.

It's a lot of stress just because of pad width? So a lot of stress on an LGP dozr,. too?

 

[Catdaddi]

Yes

How do you decide which gator to use?

I've never seen a split master on a lubed chain, always on SALT chain. Also never seen SALT chain on an excavator so it may take some research to find something off a dozer that matches up. Best bet is to call your local aftermarket u/c supplier. They will have specs on your chain and should be able to tell you if they can make it happen. Just for clarity, why do you want a split master on an excavator? Do you remove the track a lot?

I got a customer up in West Vagina and he is in the field and wanting it to help with the install. probably don't have access to a press and tired of swinging that 20lb. lol.

Depends on the chain spec, some are dimensionally identical to dozer chain but usually with much softer and more flexible links and pins. These you can sometimes substitute dozer split master links in place of the pinned links. Many of the excavators use metric pitch tracks though and as such will not have any matching dozer master links to use. Tell him to grind the master pin down a bit and weld both ends, after all if he's taking the tracks apart every other week it must be a real patched up machine anyway......

Welding the ends won't keep the pin in. It just cracks the steel off the pin and the edges of the links. Most of what I have been seeing are not pressed in anymore. A Tee head and a big cotter pin on the back. I've heard of people trying the split links but never heard of anyone being successful with using it on excavators. Excavator chains have a lot less press fit than dozers. That's the big reason the links spread on the pins and the chains get real snaky and like to come off. I have chucked new master pins in a lathe and used a grinder to make the press about a thousandth inch instead of seven thousandth of an inch.

Depends on what you weld it with. Eutectic 680 usually holds if you tension the track before welding. The headed master pins went out of style in the early 90's, don't tell me they're bringing them back?

 

[Deeretracks]

I've had good luck welding pins in on old sh*tty rails. I pre/post heat and use my scaler to peen the crap out of it.

Tell him to throw pin in freezer overnight. Goes in a lot easier.
