1/2” chain & 9/16” pads

Post by Mr. John » Thu Jun 02, 2022 12:54 pm

I was able to find a 1/2” chain for my 450d, but it looks like my current pads are 9/16. Any chance I can run the 9/16” pads if the bolts are good and tight?

Doubtful. I don’t believe you can torque the bolts tight enough to hold and make up the bolt - hole difference.

I would echo what Bruce, said, I highly doubt it.

The pads would be loose in the first 1.000 feet.

We have extra large hole 450 pads but nothing good in 1/2”.

Hi,

Sounds like a lot of spacer rings to make up to me....

But that would be faster than drilling and tapping the holes....

From my experience, 9/16" bolt holes on your old pads would indicate you have SALT chain on there right now and the chain you're looking at with 1/2" bolt holes suggests DRY chain. Just thought I'd bring up the fact that you'd be downgrading your tracks. Not that it would really matter but from what I know, the SALT chain separation is much easier with a detachable master link (alligator style) and DRY chain has the dreaded master pin that you'll need to beat out.

My thoughts exactly!! SALT tracks cost more but last twice as long. Plus being easier to install or take apart.

Can you have Salt tracks without the alligator style master? Everyone of my pins has a dimple which I thought was also a sign of Salt tracks but I do not have the 2 piece master link.

Thanks for the replies guys. I have decided to pass on the 1/2 chain and will look for 9/16.

Another question: If I replace my track pads with new ones, but only do one side of the dozer, will this screw up my operation of the dozer. Will it continuously pull to one side?

The may make them but I've never seen it. The vast majority of crawlers I've encountered have had DRY chain , mainly because they are cheaper and that's what your regular guy is going to go with for his farm or whatever. I think you'd likely find a lot more SALT chain if you went to a construction site.

I say this because if your crawler was owned by a construction company or something, there is a chance they are SALT, especially with all the pins having recesses/dimples and 9/16" bolt holes.

i have Trek rails on my 450C dozer that are supposed to be SALT according to the part number with alligator connection. There is no alligator link and every pin is dimpled. I need to split tracks to reseal a tension cylinder and not sure how to proceed

My understanding is SALT pins are actually drilled for filling with oil, not just dimpled. They will have a poly type plug in the drilled hole where they were oil filled. Lubricated tracks (not sealed and lubricated like SALT) use grease, and the pins don't need to be drilled to fill the internal area with oil. If a regular type of master pin is used, filling can be done it the field with the right equipment to install lubricant at assembly, it is not common. The alligator link allows all the pins to be oil filled at assembly in the plant. A lubricated master pin can be field grease lubed and pressed in. Since the pitch, rail height, width, bushing diameters, etc. need to be the same to fit, the link rails themselves can be visually the same for dry, lubed, or SALT as the difference is in the sealing of the pins and bushings. I wonder if you have lubricated tracks, not SALT, if the pins are just dimpled and no alligator link. Just my understanding at present, someone may have better info for you.

Best way to remove a pin is a track pin press. Otherwise, helper(s), drive pin (with a handle), a big hammer(s), heat and determination. Set up back up for the link you are driving the pin from to make your hammer blows more meaningful.
