R32 Oil Pump

[stingray]

My oil pump is on the way out and I need to change it. What are my options with the oil pump? Do I get a new one from Nissan or aftermarket? Should I source a second hand one or get it repaired? What can I do and what are the rough costs involved?

Thankyou

BTW forgot to mention it's for an RB20DET engine.

Anyone know anywhere in Melbourne where I can take my oil pump to get it inpected and repaired if possible?

How do you know that your pump is on the way out?

The factory oil pressure gauges are often dodgy.

If the oil pressure is low on a proper gauge it could be loose oil pump bolts or worn big end and main bearings.

My mechanic has taken it out and he says there's a hairline crack in the pump. He couldn't get the front crank shaft gear off so he cut that. Now I need to source crank gear as well as a slinger.

What could cause the pump to crack, old age, high millage??

I know the R32 RB26 sometimes has oil pump drive problems that destroy the pump and crank if not fixed soon enough.

I'm not 100% sure of the cause or if the problem applies to the RB20 but both have problems with the bolts coming loose.

The R33 RB26 has a stronger oilpump drive.

Jun make an adapter so you can use R33 pump on the R32 crank but I think that is only for the RB26.

A new timing gear is $49 from Nissan Spares.

Thanks, I will ring Nissan spares tomorrow. Do you have their contact details? Does the pump usually crack by itself because I have a feeling that my mechanic might have cracked it attemting to take off the crank gear.

[RB30-POWER]

Yeah, i would say your mech, stuffed it getting the gear off.

I always just cut/split the timing gear, its too hard to get a puller behind it without damaging the oil pump.

Nissan part No. 13021 42L11

RRP $47.89

Just ring whoever your local Nissan dealer is, most have a spare parts department.

Do you know what the slinger is? My mechanic said that is stuffed aswell. Its some kind of metal disc and I think it goes between the gear and pump. Is there a part number for this?

[RB30-POWER]

Its called a timing sprocket plate according to Nissan.

Nissan Part No. 13022 42L00

Its just a small metal disc to stop the belt sliding off. Should only be a couple of bucks.

Sounds as though he stuffed it, when trying to remove the timing gear.

Just confirm the part no. with Nissan before ordering.

Hi RB30-POWER, how do you go about splitting / cutting the timing gear off with-out f'ing the crank and pump? Do you use an angle grinder or a chisel or what? This has been quite a pain for me!

The reason I want it off is to change the front seal on my 4WD RB20. I am told that I will not be able to get the pump off due to the bolt not clearing the sump. Advan (Silverwater) tell me that they slide the seal out with-out taking the pump out, then slide the new seal in. Does that sound fair to you? Any healp would be GREEEEAAAAT!
