Are all of these Euro only models?
-
to my knowledge yes. there is probably some grey market ones around here though?
Note the rover, not a bmw, but has the bmw engine, and right crank.
-
Does anyone know the BMW part number(s) for the crank that will work with M42's?
-
Why the m47n crank isn't correct?
-
i dont know if you guys know this but Metric Mechanic has a "kit" M47 crank (at88mm stroke) for like $1200. they machine it and everything for you, all you have to do is install it.
by the way, i love this reference guide, very helpful.
-
you can use the m47N crank you just need anotehr piece machined. its also a little longer stroke.
You can get the crank for cheaper then 1,200 else where but yeah, you can go that route as its an easy way to go.

the cheapest i have found in the states was like $780 (plus you would have to get it machined). correct me if im wrong, please tell me if there is somewhere where you can get them cheaper, because i need one eventually when i do my build.

i found mine in Austria. I have an extra 1...
-
I bought my m47n crank from here Finland 450 euros.
The crank is from 2004 320d
-

are you selling it?
-
mhmm
-
is it correct ?

Thanks for the reference mate!
BTW, on BMW TIS 2007, I found out that E46 318d M47N has 90mm stroke without flywheel balancer and looked similar to E46 318d M47 crankshaft with 88mm stroke
The price of both crankshafts are similar, according to this site:
http://bmwfans.info/original/E46/Lim/318d-M47N/ECE/R/N/2004/10/mg-11/ill-11_3513/
If it can be used with E36 S50 B30 US M3 piston which has 86mm diameter and 32.8mm compression distance plus 135mm conrod length, the resulting displacement is 2,091cc (86mm x 90mm) with 1,5 conrod ratio. Off course you need to enlarge the bore to 86mm (2mm larger for m42 or 1mm larger for M44)
The total deck height will 211.80mm or it will sits 0.35mm lower than M42/M44 standard deck height.
What do you think?
-
In the link above, thrust bearings are shown to be on the block and also on main bearing cap. The specs offer different sized journals and a second measurement which is for different sized thrust measurements. The M42 only has provision for a thrust bearing on the upper half of the journal. The main bearing cap is like all of the others. As a result, this is a weak spot on the M42. Is the main bearing cap modified for the diesel bearing or is the crank just bolted as is?

pretty much spot on. thats interesting about the 90mm stroke though, good find. link isn't working for me though...

Price in USD or Euro??

Price is in Euro (880 Euro) according to http://www.bmwfans.info
However, further comparison on ETK 2007 between the 90mm stroke crankshaft of E46 318d M47N (BMW p/n 11217790928) and the 88mm stroke crankshaft of E36 318d M47 (BMW p/n 11212247515) shows the difference in guide bearing shell and bearing shell used on the crankshaft (different BMW part number).
The guide bearing shell and bearing shell used on the crankshaft of E36 318d M47 and M42, M43, M44, M50 and M52 engines are all similar
So this is inline with the reference guide from Mike Kowalski in the beginning of this thread.
In other words, the 88mm crankshaft of 318d M47 seems the best fit to use as a stroker crank on M42 M44 engine.
Or, can a little bit machining on the block will accommodate 90mm stroke crankshaft of E46 318d M47N ?? Any idea?
-
is the m47 crank forged or cast? Oh, can we sticky this post for easy reference?
-
its forged.
-
Does anyone know that the engine was also fitted to the Rover 75 (UK Brand) and is engine code M47R. I am trying to get more information, anyone know if it is usable?
D'oh just re-read above that it is listed, has anyone used one?
-
Reading wiki they say that the Land Rover Freelander TD4 model has a m47 engine in it. Would have to be the early years of the Freelander. However Im pretty sure we have those in north america. So could this be a way of getting this crank?
-
I'm looking into a m42 stroker, found this m47r crank, does someone know if it will fit?
Its from a Rover 75 2litre 2002 16v Type D4D M47R

as comparison:
Here is the M42 left, M44 middle, M47 right.

It looks like the nose is to short like a m47n, someone can confirm this?
thanks

Note the rover, not a bmw, but has the bmw engine, and right crank.
If the Rover is the right crank, is this the crank ?
This guy has over 10 brand new cranks available, for 95 sterling.

If we shipped a few over together, then the shipping would be fairly reasonable.
So is this the right crank ? Anyone ??????

-
does anyone have any better information as far as which Freelanders and which Rover 75s the crank we need came out of? I can't find any specific info on what engine those two cars had, whether it was the m47d or the m47n. also, some people are selling m47r crankshafts. since getting one of these crankshafts involves overseas shipping of a very heavy part, i really don't want to pay to have one shipped only to find it's the wrong one (and therefore completely useless because the m47 was never offered here so I would never be able to resell it).
-
anyone?
-
I wish I knew. I'd love to stroke the M42 & add a few goodies, but I've never found the correct info. I'd get them to take a lot of pictures...
-
Hey Guys, I'm also interested in built a 2.1l M42. But I'm confused which crank is the right way and what exactly has to be machined.
M47D18 or D20?
Just give me some infos, a friend of mine could do the job here in Germany.
If i tell him what to do exactly what to do on which crank he can give me a price.
To bore the block up to 86.5mm for example he's asking 200€ (one block)
I will try to arrange some cheap cranks, but need to know which one is the best.
Thx in advance
-
The correct crank is m47d20 with 88 mm stroke, I believe that m47d18 uses the same crank.
The incorrect cranks are m47tud20, m47tu2d20, and m47r as they have a short snout and require a fair amount of work to lengthen. But doable and they have a stroke of 90 mm.
You can spot the difference easily by the fact that the incorrect cranks have a short snout and a large timing wheel just in front of where the flywheel bolts on.
Cheers

The crank pulley bolt and washer for the M47 is a euro market only. Stock is a M18x1.5x102 bolt. A readily available alternative is the N20 crank pulley bolt which is M18x1.5x108mm. The parts list do not list any dimensions of any of the washers. For the Australian market at least, the E90 320D M47N2 washer is a possible option. Part numbers highlighted below in red.
The bolt and washer is with the engine builder and if there are any issues with them, I update. Part numbers and specs are:
M47
Hex bolt 11232248268 M18x1.5x102 M47
Washer 11232247260
M44
Hex bolt 11211721100 M16x1.5x120 M44
Washer 11231709977
E90 320D
Hex bolt 11237790922 M18x1.5x85.5 320D * too short
Washer 11237787326
N20
Collar screw. 11217614270 M18x1.5x108 N20

Hello Guys!
I've bought M47n crankshaft. My fault.
I've heard that possible modify the nose of the camshaft for install to M40 - M44. But I can't find pictures or drawing how to do that. Could You help me?
-
I bought a crankshaft with a piston stroke of 88mm
The connecting rod I used is H type 135mm long
Follow-up piston adopts 86MM forged piston
But at present I need the conversion table of the original BMW crankshaft bearing
60MM bearings are divided into three types
I don't know the thickness difference on the parts list.
Does anyone have a bearing specification table for E36?
Share with me
I will thank you very much
