w202 C36 AMG m104 engine piston rings part numbers
- Thread starter yao500e
- Start date
A0020309324 / A0030303124
Not sure why EPC is showing the same pistons rings as the M104 3.2! (91 mm Vs 89.9mm)
Can someone confirm this?
This might not be an easy task, 2 sources state the same issue with OE piston rings and mention the Piston rings dimensions:
------------------------------
"These are the rings that were in the engine (measured by my mechanic).
1.2 x 3.3
1.5 x 3.7
2.5 x 2.2"
--------------------------------
One solution mentioned was buying aftermarket piston rings (CP Pistons, Total Seal). There is one seller in Germany selling sets of piston rings for the 3.6 M104.
But I thought of another solution which needs to be VERIFIED: Ssangyong Chairman H pistons ring !? It allegedly uses a 3.6L M104 engine.
Eventually It would be possible to find them, because a few Chinese factories are also manufacturing forged 3.6L pistons sets for like $600!!

Great find and info. so, it seems piston rings only come in the set with the piston itself.
I know total seal has supplied the rings. i emailed them and its so odd that they want me to provide bore and size information. I stated to them they produced it already. are the specs not on their records and computer systems?
I also reached out to a china factory. which ones do you know about? the one factory told me they need a large quantity order to produce the 3.6L piston and rings.
thank you.
sadly. only Total Seal inc. seems to custom make them. you got a C36?
sadly, i dont know the price. give them a call. Total Seal® Piston Rings | Performance Piston Ring Manufacturer
I know a guy in France who recently had Total Seal M104 3.6 rings made.
I got new rings from a specialist near Stuttgart for my 6L M119, M117 and custom M104.

You have to tell them the exact cylinder diameter, material and ring height etc.

M104 3.6 ring sizes are follows:
1) 1.2mm top ring,
2) 1.5mm second ring,
3) 2.5mm oil ring. oil ring is an odd size.
the Cylinder bore is still 91mm
thank you

I don't remember so it wasn't significant...
Or significant for that step of work involved.
You need to inquire with them.... Important as said to share the exact (measured) cylinder diameter - not what is written in the book.
If you see from factory there are tolerance steps which are not communicated in the regular documentation as well as this applies for any reconditioning.

Hello GSXR, what does this 100.035 number signify? thank you.
I see ok. Since they made custon 3.6 M104 piston rings previously, hopefully, they should have it on record in their database to custom make it again. thank you.
hello @gsxr .
I assume if this is purchased from Mercedes its a set of 6 pistons as part of a set?
thanks again
The piston/ring assemblies are sold individually. Note the EPC quantity required is 6.
Doesn't matter though... they are NLA.
