Supercharger Maintenance

I've jotted down some info I found Googling around for a couple of hours. Please do not treat what I post here as gospel! Use as a reference only.

TRD Supercharger
The TRD supercharger(intercooled roots-type Eaton M90) is considered a sealed non-serviceable unit with a maintenance free service life of 100,000 miles. As such, your dealer will have no procedures to follow for doing regular maintenance, so you are on your own.

From what I've read, there are a few things you can do to help extend the life of your supercharger well beyond it's expected 100K life.

NEW: 06/02/2014
TRD S/C Maintenance How-To from the Tacoma World forums. This is a how-to for the nose drive oil change, impeller bearing re-grease, drive coupler replacement, and drive belt replacement.

1)Belt inspection/replacement
Make it a habit to inspect your SC belt and replace it when it's worn. I've read the expected life time of a SC belt is approximately 10K miles. It is recommended to always carry a replacement belt with you and know how to change it out. You never know when it will break. Also, worn/loose belts can slip, robbing boost.

Replacement SC belts:
TRD PTR30-35070 Dayco 5PK1790
Goodyear Poly-V Gatorback 4050705 5PK1790

Belt tools: (not required, but makes the job a little easier)
Serpentine Belt Tool Kit

DIY:

2)Check your coolant reservoir fluid levels.
The coolant reservoir should look like this when working properly. Do not overfill the reservoir. You can check this by turning the key to on without starting the engine. Check for leaks if you have to keep topping it off.
Toyota Coolant, radiator and supercharger:
Toyota Super Long Life Coolant, #00272-SLLC2 (the pink stuff)

3)Check that your coolant reservoir pump is still working.
Check your reservoir pump on occasion to make sure it hasn't quit working. This check is done when you check your reservoir fluid levels and test the coolant flow.

Replacement pumps:
Johnson CM30P7-1 pump. Stronger, more reliable pump. Check eBay, ~$140
Ford Racing LIGHTNING Intercooler Pump. A direct replacement. Check eBay, ~$110
TRD Intercooler Pump part# PTR29-35062

4) Changing nose(snout) oil
The next thing you can do is change the nose oil out every 30,000 miles. The nose bearings will wear over time and start to shed metal. That metal gets into the oil and then makes it way into the main impeller bearings. This can cause the main impeller bearings to wear and now we are talking a SC rebuild($$). Changing the nose oil out every 30K will help keep that nasty metal away from the expensive impeller bearings. You will need 6 ounces of oil. The GM oil comes in 4oz tubes, so you will need 2 bottles.

5) Coupler replacement
The most common part to wear out first(besides the belt) is the coupler bearing. The holes in the coupler get worn and it sounds like rocks rattling around when at idle.

6) Nose rebuild/replacement
As the nose bearing wear, the normal rattling sound the SC makes will get much louder and more pronounced. It can get pretty bad and indicates that the SC is overdue for at least a nose drive overhaul.

7) Inter-cooler cleaning
When you have the SC pulled for the 30K nose oil maintenance, it is also a good idea to clean up any crap/oil accumulation on your inter-cooler core. This will help the SC be more efficient at cooling.

Consider adding an oil catch can to keep the blow-by from collecting on the inter-cooler.

Re: Supercharger Owners Thread!

You guys would get beter performance if you helped that forced induction flow better. I am thinking high flow rate intake, long tube headers, y-pipes or straight dual, and high performance large diameter exhaust.

Re: Supercharger Owners Thread!

I'm not unhappy with the performance I get right now. I would love to add a aFe CAI, APR X-One, and NST Overdrive kit, but these would kill my warranty. So it's not going to happen... at least for a while.

Pretty sure this system was designed to work without any off that stuff.. I like my warranty and have a sports car and one of these which runs in the 9's.. Notice the Plate.. Oh and why can't a FAT PIG be fast on a Dirt rutted road where a sports car, motorcycle would be really slow.. Why does everyone compare power to speed on pavement? I'll put my FJ or TJ against any Nascar in the desert.

Re: Supercharger Owners Thread!

Does the addition of the SC make it "Tactical"? LMAO. I love my SC and what it did for the FJ. Now I have to go dig out the paperwork and post up the info or face "Flaming Troll Syndrome".

It's not that simple. As soon as you open up the exhaust like you've described, you will create issues with building boost pressure in the intake manifold. Not sure about our applications, but on the V8's I've done we'll lose 2-4lbs of boost.

You can offset this by increasing boost pressure, as long as the supercharger,engine and fuel system can handle.

We've run into this problem on the GT500 Mustangs. We installed the 2.6 blower pulley, intake and a proper tune and made 540rwhp. Then added long tube headers and a cat-back, re-tuned and picked up 5 more hp. But we lost 25lb/ft of torque right in the middle of power band.

So we upped the boost some more to compensate by changing out the crank pulley and got back to 15lbs. But intake temps spiked indicating that we had maxed out the blower.

Re: Supercharger Owners Thread!

I have updated the original post with the start of a "Supercharger Maintenance Guide". Understand that I am not a supercharger expert and am "learning as I do".
