Caterpillar thread size

Ted Allen ยท 2022-10-23 19:29

I have a 2003 Cat D5N xl, AGG01698 Serial Number, rebuilding undercarriage and broke a bolt in the roller carrier that bolts the rollers to the roller carrier. Need to tap the hole out and I can't find a tap locally. Can anyone tell me the tap details I need so I can order one. Local cat guy is no help. Thanks

    Probably 16mm x 1.5. But, order the bolts first, then double check thread size.

    Measure the one of the other bolts you took out?

    M16x2.0 for all the upside-down bolts.

    16x2.0x70mmx10.9 bolts part#8T0357, order locally not from Cat.
