clay based grease

I ordered 2 tubes of clay based grease from MOT, and received mobiltemp SHC32 red grease from MOT with attached note that said this is what they are using instead of clay based grease.
My question is has anyone on the forum used this grease or have contacted meritor and got their approval.
I am not questioning MOT but have read numerous posts that stress to use clay based grease ONLY?
Any help is appreciated as always.

I insisted on the clay-based grease a few months ago when we had our brakes overhauled (new rotors, pads, helper springs) and my truck shop had to order it from, I think, Meritor directly.  Came from Illinois, as I recall.  Anyway, I insisted on the clay due to the warnings here on the Forum.  I had to buy way more than we needed, and have some tubes in storage.

After checking into the Meritor specs specifically relating to viscosity, high temp requiremet and low temp requirement, many Grade 2 lubes available today meet the Meritor specs that are NOT clay based.  I would contact Meritor direct and ask if the lube you were sent meets their spec. and call MOT to verify that it meets ALL grade 1 requirements, then you will know for sure.  The Meritor tech bulletin that applies to our year coaches has been superseded by a new revision.  I did not download the new specs from their publication section.

Scot, MOT is the one that sold me this grease saying it is all they use. Now I am definitely perplexed. I sent a email to Meritor, but no reply so far.
Will keep you posted on what I find out.

I had MOT do my coach a couple years ago. They also used Mobil one synthetic aircraft grease 28.

If 32 is the next iteration it would be fine.  I have had no issues with it.  I know a number of other FT owners used the same thing. It is red grease.

Silly question, but not being technically inclined, I have to ask. What is this grease used for? Does it have a specific purpose, or is it more general usage in nature? Apologies in advance if I am being dense, but I appreciate the knowledge.

WaltH - The grease that Meritor specs is NLGI Grade 1 and is used to lube the brake calipers.  It has specific High Temp and Low Temp Spec that are outside the "normal" parameters.  I understand most chassis lube used today is a generic product that will not meet the Meritor Grade 1 Spec.  Many synthetic greases produced today conform to the  MeritorTemp Specs.  The Grade 1 grease also has a thinner viscosity, like tomato paste.  When we had our Brake calipers purged a month ago because it was lubed with grade 2 at a Cummins shop,  I asked the Peterbuilt shop to get me product that conforms to the Meritor specs.  The clay based grease/lube was originally specified for use in the brake calipers by Meritor as well as certain synthetics.

I am somewhat anal and sometimes I must go to the horses mouth, in this case Meritor, to first verify the actual spec and then to confirm that what I intended to use meets their specification.  I can now sleep at night knowing I got the right stuff.  ;D

I also use Mobil SCH 32, it is a red and clay based. I talked to Meritor, a while back it seemed like their prime concern is the max high and low temp ratings of the grease.

 Mobiltemp SHC™ Series
Grease
Product Description

Mobiltemp SHC™ Series products are supreme performance antiwear greases primarily intended for high temperature applications. They combine the unique features of polyalphaolefin (PAO) synthetic base fluids with those of an organo-clay, non-soap thickener. The excellent resistance to thermal/oxidative degradation provided by the PAO base, coupled with the excellent high temperature structural stability and high dropping point of the clay thickener result in outstanding high temperature greases. The wax-free nature of the synthetic base fluid and its high viscosity index also provide superior low temperature lubrication as well as excellent film protection at high temperatures.

Because the PAO base oil has low traction properties (compared to mineral oil), Mobiltemp SHC Series also offer the potential for energy savings through reduced friction and lower torque, and reduced temperatures in the load zone of rolling element bearings. The Mobiltemp SHC Series is available as three products: Mobiltemp SHC 32 is an NLGI 1 1/2 grade with ISO VG 32 base oil; Mobiltemp SHC 100 is an NLGI 2 grade with ISO VG 100 base oil; Mobiltemp SHC 460 Special is an NLGI 1 grade with ISO VG 460 base oil, plus molybdenum disulphide for extra wear protection.

The Mobiltemp SHC Series of greases is used in numerous high temperature applications, as well as applications where low temperature start-up or running torque is important. They provide excellent grease life at high temperatures and offer extended relubrication periods and energy savings potential.

Mobiltemp SHC Series greases have become the products of choice for many users, in many industries worldwide. Their reputation is based on very wide application temperature range, and their excellent overall performance.
 
Features and Benefits

The Mobil SHC brand of oils and greases are recognised and appreciated around the world for their innovation and outstanding performance. These molecular design PAO synthetic products, pioneered by ExxonMobil research scientists, symbolise the continuing commitment to using advanced technology to provide outstanding products. A key factor in the development of Mobiltemp SHC Series was the close contact between our scientists and application specialists with key Original Equipment Manufacturers (OEMs) to ensure that our product offerings would provide exceptional performance in the continually evolving industrial equipment designs.

Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of the Mobiltemp SHC Series lubricants. These benefits include superb high temperature performance including thickener integrity and oxidation life with enhanced bearing protection and bearing life.

To combat high thermal exposure of the oil our product formulation scientists chose PAO synthetic base oils for Mobiltemp SHC Series oils because of their exceptional thermal/oxidative resistance potential. Our formulators used a special clay thickener to provide excellent structural stability and high dropping point. Mobiltemp SHC Series greases offer the following benefits:
Features   Advantages and Potential Benefits
Outstanding high and low temperature performance   Reduced downtime and lower maintenance costs
Excellent resistance to oxidation and maintenance of grease structure at high temperatures   Extended service life with longer intervals between relubrication
Low coefficient of traction   Reduced energy consumption potential
Outstanding low temperature pumpability   Easier low temperature start-up and lower running torque
Very good antiwear protection   Extended bearing life, reduced unanticipated downtime
 
Applications

Mobiltemp SHC greases offer excellent high temperature grease life, bearing protection and grease integrity along with excellent low temperature capability and good wear protection. Specific applications include:

    For Mobiltemp SHC 32
    Sealed or re-packable ball and roller bearings
    Splines, screws and some enclosed gearing
    Extreme temperature applications with a recommended operating temperature range of -50º C to 180º C (with appropriate relubrication intervals).
    For Mobiltemp SHC 100
    High speed bearings and thrust bearings where a wide temperature range is desired
    It is particularly suitable for use in electric motor bearings where operating conditions demand reduced friction, low wear and long service life
    Extreme temperature applications with a recommended operating temperature range of -50º C to 200º C (with appropriate relubrication intervals).
    For Mobiltemp SHC 460 Special
    The presence of molybdenum disulphide makes it particularly suitable for the lubrication of sliding machine elements such as cams and ways, which are subject to long relubrication intervals, limited motion or shock loading.
    Oven conveyor or kiln bearings which are subject to high temperatures or cycling between high and normal temperatures
    Extreme temperature applications with a recommended operating temperature range of -40º C to 180º C (with appropriate relubrication intervals).

More of the same, from my son who works for Exxon Mobil ...

"Hey – This is the correct grease for this application.  In fact, this is clay-thickener type of grease so the recommendation is right.  Mobiltemp SHC32 is one of our highest performing greases and is primarily intended for high temperature applications (like brakes).
 
From our Product Data Book ...
 
Mobiltemp SHC 32 is an organo-clay-thickened antiwear grease containing a synthetic hydrocarbon base fluid. The exceptional resistance to thermal and oxidative degradation provided by the base fluid, coupled with the excellent high-temperature structural stability and high dropping point of the clay thickener results in an outstanding high-temperature grease. The wax-free nature of the synthetic base fluid and its high-viscosity index also provide superior low-temperature lubrication, particularly in applications where low-temperature startup or running torque is important. Mobiltemp SHC 32 is recommended for the lubrication of sealed or repackable ball and rolling-element bearings, splines, screws and some enclosed gearing. It has an operating temperature
range of -50°C to 180°C.
 
Good luck with it xoxo G"

Well, ok then.  If anyone wants any of the Meritor clay-based stuff just let me know!  I should have trusted my shop, I guess, who told me I really didn't need to spend the big bucks for it.
