The Merchant Automotive 10001 Transfer Case Pump Upgrade Kit for your 01-07 GM 6.6L Duramax is the best upgrade you can make to your GM transfer case (model 136, 146, 246, 261, 261HD, 263HD, 263XHD, 261XHD) to prevent the ever increasing problem of pump rub.What is pump rub?
The GM transfer cases use a gear pump inside the case that is driven off the mainshaft. The pump forces oil to the planetary as well as the drive sprocket sleeve. Because the pump is driven by the shaft, the housing of the pump must 'float' in the rear housing. There are 5 tabs around the housing that fit into spots in the rear housing to position the pump. Over time, the pump can start to wear on the rear housing. GM installed a spring steel clip in the housing intended to prevent wear but the clip can break and render useless
Being that the pump housing is aluminum and is a harder material then the magnesium rear housing, it can wear a hole in the rear housing and cause a very small leak. This leak is high enough in the case that it typically will not leak when vehicle is not moving and therefore not leaving any drops on the ground. Typically the condition is not found until there is transfer case damage from running the case out of fluid.With installation of this kit, you will have a LIMITED LIFETIME WARRANTY against pump rub.
Included Components:
- Merchant Automotive billet transfer case pump housing
- Transfer case adapter gasket at trans
- RTV Silicone
- Blue Threadlock
- Merchant Automotive sticker
If you already have a hole in your case, its recommended to install a new rear housing for a proper repair. Lifetime warranty will only apply to installations with a new rear housing.

Frequently Asked Questions:
What do I do with the OEM anti rattle clip when installing this upgrade?
You can discard the factory clip during installation of this kit. Its been designed to work with the clip removed.
What other parts will I need to install this upgrade kit?
We tried to make the kit all inclusive for a basic installation. This is taking into consideration of course that its being installed as preventative measures. If its being installed as part of a repair or after pump rub has occurred, there is no real way to know the extent of the damage inside the case until it is torn down. Most times, as long as the case has not run out of fluid, it can usually be repaired with a new rear housing and seal and prevented from ever happening again using the upgrade kit. Regardless of the reason for installing this upgrade, you will need to refill the transfer case with oil. We recommend our Performance Transfer Case Oil for use in ALL transfer cases.

Very nice product
Size: 30 Count (Pack of 4)
I absolutely love these facial wipes. I used the Pore Refining pack first and noticed a change in my pores after about a week of use. I'm over 60 and as we age our pores start to get a little bigger and this wipe closed them up. I'm very pleased with this facial wipe. They are small, so I use a different facial wipe to get make up off then use the Pore Refining wipe to go over my face again. I haven't used the other three types of wipes you get in this 4-pack, but look forward to see any results from them.

Indispensable!
Scent: Unscented, Size: 25 Count (Pack of 4)
I love these so much that they are part of my monthly subscribe-and-save program. They have absolutely no scent, which is great, because too many products are over-perfumed. They take off all of my makeup gently. There is no stinging or drying sensation. The cloths are well-sized and the package stays shut when not in use- the cloths do not dry out. After I use a couple of these each night to take my makeup off, I follow up with a gentle, moisturizing facial cleanser. My skin is soft, clean, and happy. I highly recommend these!

A Staple in my Skincare Routine
Scent: Unscented, Size: 25 Count (Pack of 3), Scent: Unscented, Size: 25 Count (Pack of 3)
I've been a huge fan of micellar products ever since they came onto the US market and these Simple Micellar Makeup Remover Wipes are no exception! Simple products are known to be gentle and easy on the skin. These wipes stay true to the brand and feel great on the skin!
I have combination, sensitive skin and over the years, I've become quite diligent in taking my makeup off before bed. Although I have tried countless popular brands in the past, these Simple Micellar Makeup Remover Wipes are the ones I keep coming back to time and time again. These wipes are my first step of action in removing my makeup and they do a pretty great job of taking off everything. I usually hold the wipe over my eye area for a few seconds to allow the makeup to break down and come off onto the wipe--I've found that this does a good job of removing my mascara, eye liner and shadow. These wipes do not cause any irritation to the eye area and are great to use on the sensitive skin of the face. To take off stubborn or waterproof makeup, I just apply a liquid eye makeup remover directly onto the wipe and have found this to be the easiest and least wasteful method. I usually wash my face afterwards with a gentle cleanser and continue on with my skincare routine. However, on the nights I'm really tired, I rely on these wipes to remove all of my makeup. These wipes do not leave any type of chemical residue behind and make my face feel fresh and clean.
The Simple Micellar Makeup Remover Wipes are a staple in my skincare routine. I keep one pack in my bedside table for easy access on the nights I'm too lazy to wash my face, one in my vanity, and another in my gym bag--I clearly like to stock up! I highly recommend these wipes; they are a must try for everyone!
