4age oil pump part number.

[too_quick]

Hey hey,

I'm rebuilding a 4age smallport bottom end to stick under a bigport head in my ae82 twincam and i need a new oil pump. The pump i took off the engine doesn't have a part number on it so i was wondering if other people had a number and how many variations are out there ?

i have the ae101 4agze part number at work, if no one finds it for ya but im sure someone here will have it.

Well the smallport 16v oil pump part no. is 15100-19036.

There are a few different part no.s for the bigports so there must be some variation, although you'll probably find all the 16v ones fit.

15100-19036. thats for smallport but i think its the same for ae101 GZE aswell??

EDIT101: Golberg already had it.

there are 3 types of oil pumps available for the 4A engines.

here are photos of the inner workings of the early model...... 15100-19025 which supercedded too.....


......... 15100-19026... GUESSING HERE..... it likely equals the finer tooth model pump Bill was talking about


as well as what Bill refered to as the "squarer" tooth model.....15100-19036

I believe the 20V oil pump is a better design and supposed to stop cavitation at higher rpm over the earlier pump. I haven't had them side by side to compare but may be the difference as shown above.
