Hello Australian Friends.

One of the gang here who lerks on M3forums had ordered some rod bearings for his S54. Short story is the owners in the USA have been looking into how to prevent or slow the spun rod bearing issue. So we all banded together, did some research and found WPC which treats and hardens the metal. We also made a account for the BMW community to use.

As this is a USA based company we deal it works better for the gang here to buy as a group. As there is one member already ordering I am seeing if there is anyone else who might be interested.

Here is some info from the posts

three separate patents 1. Surface Finish Heat Treatment 2. Wear Prevention of Sliding Parts of the Metal Products 3. Diffusion at Normal Temperature Penetration Coating This has been around for over 30 years, is used in F1, and has a patent.

A example of the same bearing kit from say bimmerworld is 500. As we did a collective effort we are doing this at cost.

-------------------------------------

Here is the S54 Kit.

S54 Bearing Kit -
$226.44 -- 6 Upper / 6 Lower bearings
$10.91 --- Group rate shipping to WPC
$39.00 --- WPC cost with 20% discount
$20.30 --- Shipping from WPC to me then to you
$296.65 -- Total for GB each
$5.00 ---- Just in case shipping is incorrect
$301.65 -- Total to be paid


WPC treated OEM bolt pricing would be as follows -

Rod Bolts
$42.90 ----- x12 Rod Bolts at $3.41 each

Shipping to you guys was $50.00 so if you get others you can spread the cost.

Currently a owner in jamisontown has ordered a set. I am placing the bearing order for him and other on 3/31.

PM me for questions or if you want to order.

Cheers

Is this a common issue for the S54 in the Z4M?

It is a common issue for any S54. That means M3, Z4M and Z3 M.

Also the S65 motor has been having this issue.

Myself and others with the S54 have been buying a set to replace the bearings even if the recall was done. Also the S62 and S65 owners are buying them just to be safe.

ok thanks, if i were to purchase these bearings who would you recommend do the install? BMW? do you have the part numbers and what brand are they?

Do you have a independent shop you trust? BMW will charge you more than a indy shop.

The part numbers are as follows. Remember if you are a 2001-2002 motor you do not need bolts. If you are 2003 - newer you need new bolts. Some people like ARP but in our long discussions on other forums we found the cost and tourque procedures to install them SUCK. So OE is fine.

Upper (blue)

Lower (red)

2003+ Rod Bolts

Here is the LONG community discussion on the process.

2. Wear Prevention of Sliding Parts of the Metal Products
On sliding parts of metal products, a lubricant is usually used. Under certain conditions, a lubricant dries up and friction occurs. By spraying abrasive, the surface structure becomes surface pressure resistant, creating small indents to make it difficult for lubricant to dry up, and making a near no-contact state, reducing the oil temperature and preventing the friction. When WPC treatment is applied on engine parts and other sliding parts, slide resistance is lower, increasing the power and providing higher fuel efficiency, and shortening the initial engine running-in period. It also prevents burns and scratches.

3. Diffusion at Normal Temperature Penetration Coating
There is a limitation in physical property of a metal material. By spraying metal particles, its component element is diffused over the material surface and the diffused coating, and the surface gets alloyed, to strengthen the material. The treatment is used for pre-treatment of the plating and coating to increase the adhesiveness. By spraying metal particles of low melting point and low hardness, room temperature dry plating is possible.



************************************************** *************************************


...and #1 (which wasn't used in our application) for reference only

1. Surface Finish Heat Treatment
Surface temperature of powder metallurgy alloy increases by fine particles peening, and metal binder in the powder metallurgy alloy will get soft, and each grain will combine solidly. Structure around the surface will be changed to be smooth and high hardness and adhesion of grains will be enhanced. Therefore, it is possible to increase wear resistance and durability of powder metallurgy alloy. Using this technique for cutting tool made of powder metallurgy alloy, we can obtain the cutting tool having the good wear resistance, durability, and increasing mechanical characteristic such as resistance to chipping.

Thanks for the information. Would you know approximately how many hours this will take to do?

Honestly that is the best DIY thread out there. If you have a lift or some good jack stands you can do it in a weekend.
