I usually go to NAPA for seals, bushings, bearings and such as the nearest Cat dealer is another 48 miles away. Measure the shaft(s) and bores if the seals were destroyed when you took 'em out, they can cross reference 'em to more common numbers.
From my notes:
The small dia. seal is a CR #5662
The large dia. seal is a CR #11223
The outer shaft can be saved with a SS99112 speedy sleeve but positioning is critical as it's ony 0.313 wide. It's possible to stack two.
The inner shaft is still available from Cat...$126.63 last time I bought.
Bushings are steel and don't wear all that much....also can be interchanged from top to bottom.
7W278 is an oldy and uses the (cheap) filter, same as fuel filter element.
Here is a parts breakdown for the control valve, little later serial number but same parts. (had on file)
HA! you guys are the stuff. Are those cross reference seal numbers from Napa? Will i have to get the large 27? bolt hyd. case pan gasket from Caterpillar?
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
