Inlet Camshaft for 73 280C
 

Hello, I have a 1973 (LHD) Mercedes W114 280C. I am 15 months into restoring.
engine number: M110 921 12011896.
I need a inlet camshaft to fit, part number: 1100519101
I have seen similar ones that state they fit with part number: 1100517401 so i am unsure and no one can give clear answer...
Seems a very rare engine as its the carb not injection version so only around 5000 made. I found that a 280CE exhaust cam and housing seemed to fit but can't solve the inlet cam issue... ah, help!
Any advice? Im in the UK.

I am a bit confused regarding exactly what it is you are looking for.

The picture you provide shows the intake cam. Is this just a picture you found on the web or your actual engine?

Okay, after having a second cuppa and re-reading your post I have a better understanding of what you are looking for.

The cam from the 280SE is not a good fit. It is made for a higher compression engine, and you will actually lose power on the carb'ed version. Overlap, valve timing, etc.

You need to find a matched set, or at least the same version of camshafts.

You could try these guys:

Or failing that, buy a set from Ebay and maybe send them to Delta Camshaft in the U.S. or try:

O:

That engine (and the whole car for that matter) are US spec. 1973 all USA, and 1974 all except California.
If you will disassemble the camshaft part # it reads thus: 110 051 91 01. The 91 is the cam profile code and is stamped into the rear face of the rear journal of the camshaft. A camshaft with a 33 code can also be used in the .921 engine.
All of the M110 camshafts will physically interchange, although the profiles differ.

Thanks Mike and Frank.
Yes that's the actual engine.
I bought a cam from Germany for the M110 engine but it didn't fit.
Now im trying to find a compatible one in the UK or Germany or USA but way slower and more expensive.

Didn't fit? How didn't it fit? That's a new one on me. You do know the cam journals are sized and the M110 cam is installed from the rear, yes?

O:

The picture you posted shows an inlet camshaft in the cam box.
1) What is the code # of that camshaft (stamped into rear of shaft)?
2) Do you have an exhaust camshaft, and if so, what is the code #?

Well the mechanic showed me, he put the cam in and it didn't line up, so wasn't held in place.

I will upload the photo of the old housing and cam (inlet) we want to replace.

Then after will upload the new one with the 280CE exhaust cam fitted.

Hopefully that will explain it.

and exhaust

The exhaust cam has this code on it: 110 051 1601

Two peoples, separated by a common language.


The first of these two pictures is simply another view of the inlet cam, not an exhaust as claimed.
The second of these two pictures is of a casting number, not a code #.
For the third time: The code # is stamped into the rear face of the camshaft!!


These errors are likely attributable to the consumption of warm beer.

Hi Frank, Not sure if i have it wrong or my mechanic (which seems unlikely). Must be me. Can I email you all the photos I have to make sensei of this?

PS no code on the camshaft...

These are the stamped numbers (codes) to which Frank is referring. Found on the rear of the camshaft.

Code on intake cam:

Number on intake cam:

Code on exhaust cam:

Number on exhaust cam:

This is from a 1973 /8 280 U.S. version (carbureted). It appears the exhaust cam has been replaced with an aftermarket cam. The intake is an original Mercedes. Note the differences in cam numbers and stamping.

Thanks so far for advice. Sorry for delay, mechanic away on holiday and me working.
