Default oil pump timing question

I bought Eric the Car guys video for the timing belt change...I've done all the seals, replaced both tensioners, the water pump, and I am about to put the belts on, but have a question.

Does the oil pump really need to be set to time? The car Eric was working on had the oil pump out of time...pretty sure my pump was out of time....just wondering...

thanks in advance.

Hmm I am not sure I understand what you are asking, the oil pump itself doesn't have to be in any sort of "time" whatsoever.
To install the oil pump the flat surfaces of the inner rotor must line up with the flat edges on the crankshaft but that has nothing to do with engine timing or the belts.

Now there is a pointer on the oil pump housing that is used to align the lower timing gear at TDC, is that what you are referring to?
There is no way that this mark can move though as it is part of the cast oil pump housing.

there is a round dot on the gear itself. According to ase certified mechanic, and the haynes manual, the oil pump is set to time in relation to TDC. My haynes does a very poor job of showing how the two marks line up.

here is a video - my gear was grossly off this mark...wondering if anyone has any input.

Correct, that mark on the lower timing gear corresponds to the key way and when aligned to the mark on the oil pump housing the crankshaft is at its TDC position.

no, no, no, no....not the timing gear, the oil pump gear - watch this video

http://www.youtube.com/watch?v=KtJQvZ8UcAQ

go to roughly 5:28...by at least two sources (ase cert mechanic, haynes manual), the oil pump should be in time. The question isn't should it be timed, but rather, what happens if it's not.

LOL, no wonder why you had me so confused.
Thats not the oil pump, that is the rear balance shaft.
Disregard any marks to align the rear balance shaft sprocket and instead use a 4x100mm bolt pushed through the rear service port, its covered by a bolt, and through the balance shaft itself.
This locks it in place so you can install the balance shaft belt.

that gear doesn't drive the oil pump?

my balance shaft is in time

My crank is in time

my cam is in time

My oil pump gear is not in time - can someone tell me what could result from the oil pump gear being out of time.

Thanks

yes, I'm swallowing a little crow - it's not you, it's me. I was led to believe that rear gear drive the oil pump in addition to being the rear balance.


Sorry for the confusion...100% my ignorance.

lol, no worries man I'm just glad you know what everything is now, should make your task ahead much simpler.
You should check out the timing belt/balance shaft write-up in our FAQ section, it covers this procedure in detail.

great advice - it helps knowing the proper terminology...I was searching for oil pump timing instead of rear balance shaft timing.

here it is for future generations:

https://honda-tech.com/forums/honda-accord-1990-2002-2/timing-balance-shafts-96-accord-2-2l-2249804/

I marked the timing on the gear before I removed the belt - be interesting to see if it was off (pretty sure it is)...

thanks again for your help and patience, dglassmyer

As the guy in the video said, the rear balance shaft is geared, so the mark you made won't necessarily be the same spot. As I remember there were three or four different spots where the external gear could end up being clocked to when the balance shaft was in time.

I removed the rear plug behind the gear last night...looks like there is only one way this will go on with the 6mm "holder" in place.

I made this video yesterday....hopefully it will help someone else. The top marking is very hard to see, I think the screw driver ensures the shaft is in the right place.

Also, if you spin the shaft, you'll notice it will settle "close to" where it should be...hopefully that makes sense.

Yes. And make sure that the dimples are aligned to their marks on the oil pump housing like the vid had shown.

Just wanted to give everyone an update on the above. The engine is in the vehicle, and running smoothly - no odd vibrations, no leaks. I believe the way I described doing the pump in the video(with the screw driver) is 100% correct, but I also think honda sells a specific tool for this alignment (I bet it looks a lot like a screw driver).

Thanks again for everyones help from above.
