    Forgive me for asking something that many of you may know but I have search here and online and can't seem to find an answer.

    I am putting together a list of parts I need to do all the maintenance and some repairs to my new to me cat 426 backhoe. I bought the parts manual as a PDF from Cat and am a bit confused on one thing.

    In the maintenance section they list two different part numbers for oil filter. One has a description of "AS" next to it. What does the "AS" stand for or denote?

    While I look at other items they use "GP" next to some descriptions. What does "GP" denote?

    Thanks for helping out a newbie.

    7W2327 is the spin on engine oil filter, at least on my 3.

    4T7948 is the spin on hydraulic filter.

    119-4740 is transmission filter for either style transmission.

    The "AS" is for "assembly", like the air filter has element AS listed.

    I am pretty sure AS - Stands for assembly. GP- general purpose.

    GP definitely denotes general purpose when relating to buckets. In Cat parts though I guess it could be either depending on what part (no pun intended) of the machine you are working on.

    Thanks so much. GP=Group and AS=assembly. This is excellent. I was drawing a blank. Now it seems so silly that I even had to ask.

    Never be sorry for asking. It's how we all learn.
