Engine Dimensions
 

A request for a couple of engine dimensions:

For the M104, the height from the centerline of the crankshaft to the highest point on the cam cover, and from the crank center to the lowest point on the sump.
These two measurements may be the same or very close for the OM606.

If a M103 were at hand for comparison, those measurements would be of interest also.

I have an M103 on a stand. I'll get the measurements this weekend. Shoot me a PM to remind me if needed ;)

I can only help out with half way house information.

M102 engine measured in the car

Measurements probably good within a centimeter (well I hope so I did put in a bit of effort to get them!)

Width of engine =>

Measured from side of valve cover next to the alternator (so standing in front of engine that's on the left - but is actually on the right hand side of the car) to where I think the side of the block stops - difficult to see because of all of the CIS crap in the way

37cm - this is the worst measurement I made!

Engine height =>

Measured from top of (front) anti-rollbar to top of valve cover + measurement from top of anti-rollbar to bottom of sump (lowest point of the sump)

58.5 cm - probably a pretty reliable measurement

Length of engine =>


Measured from where I know the back of the block extends past the back of the valve cover - where the block joins the gearbox to just behind the front pulleys (so you have fans and **** in front of this measurement before you get to the radiator)

60 cm

Bear in mind M102 was fitted to W201 and W124 models as well as the M103. I assume the length of the M103 is gonna be close to the M102. I assume the height of the M103 is gonna be close to the M103.

If I've done it all wrong and I'm 'ucking hopeless - I'll give it another go under strict direction!

Thanks for the effort; more than I anticipated.
M102 & M103 should be the same height and width; the M103 is two cylinders longer.

Sorry I didn't explain that bit of my thinking.

The M102 is pretty tight in the W201 chassis - the M103 can't be much more than 5cm longer. The M103 does need the cross member for the bonnet / hood catch to be removed to get the engine in and out. We'll have for gatorblue but I'd be surprised if it was much more than about 65 to 70cm.

(And don't forget the cylinders are smaller albeit more numerous!)

32 1/2 inches as far as I can tell. Its not easy to get an exact measurement since the engine and stand is buried in the corner of my garage. Once I get some cabinets hung and out of the way I can get an exact measurement. The figure I posted is from around the bell housing bolts to the front of the fan.

Thanks for taking the time; if you will re-read my original post, you will see that what I requested were heights, using the crankshaft as the datum. That is, the height (vertical distance) from the crankshaft to the highest point on the cam cover, and likewise, the distance from the crankshaft down to the lowest point of the sump.

Sorry Frank that's probably down to me confusing things and then you joining in with the six cylinder comment!

If you want the heights from the centre crank position of a M102 up and down please say.

Stretch:

At your convenience, those vertical measurements would be appreciated.

Drat it is already dark here - I'll do it tomorrow.

For the sake of completeness (and I know you don't want this but I guess someone will see it and ask some time in the future!) the length of my M102 to the end of the pulley section of the fan is 66cm - 69cm for fan blade clearance.

Right now that's done

The centre of the crankshaft pulley to top of the engine measurement isn't so easy to do in a car with a radiator in place but I'm pretty sure that it is 41 cm (with an error of about 0.5cm)

Comparing that with my previous measurement of 58.5 cm for the total height the bottom of the sump is 17.5 cm lower than the centre of the crankshaft pulley.

(On a dry day I'm prepared to check that!)

Anyone have the sizes of the M113K?

Thanks,
Dave

This is a nine year old thread, so you would be wise to start a new one with a title such as "Request for M113K external dimensions."
