Picture of the camshaft sensor pick up point on M60 at TDC

[naika]

Hi Guys,

I would need to see a picture of the position of the sprocket holding the camshaft sensor pick up point at TDC.
Does anyone have it on hand to share?

I am going through the OBD1 conversion on the M62, but I don't have an M60 on hand to compare the pick up point position and duplicate on the multi point pick up of the M62.

If anyone can help, that would be greatly appreciated.

thanks in advance

Franck

Did you search and read the thread that was put up about the M60 to M62 conversion, Moroza?

Edit - heres a handout....

Thanks,
I've seen those 2 threads, they actually helped me get the conversion done.
But right now I only need to know the pick up location on the M60 at TDC, and can't find any pictures :(
Even the picture of the M62 would be useful.
Anyone?

This photo may help, I took it when I was timing the cams after a head gasket change. The drive plate pin was in place and obviously the cam tool is in place at TDC No.1 cylinder.

Thanks a lot, that picture is of great help.
So it seems that the pick up point on the sprocket is right in front of the sensor at TDC?
If so, then it goes against my assumption... That's a problem.

This is becoming a headache :(

On my M62, I had to modify the multi-point pick up wheel in order to convert it to OBD1 and based on information I received and found on the site, the pick up point should be at noon and not 6 o clock.

I'm confused.

sorry to hijack but where is the pick up for TDC on the M62? I took the pick up wheel off last year and then the snow came and stupid me didn't mark where it went so now I have no idea how to figure out TDC using the cam sprocket with out the pick up ring there.

Where are you getting the other information? Who says it should be at 12 at TDC?

I don't know, but am curious as I am on my way to go get an M62 and do the same thing tomorrow morning.

Well, Stevie C who documented the conversion on another thread modified the wheel (m62 wheel that is) and when my engine was at TDC with the wheel on the lobe he left on was at 12 o clock.
He confirmed that he duplicated the position of the pick up from an m60, but I'm getting two different info, therefore I'm stuck.

Sorry, I don't have a picture of m62 pick up wheel at TDC, I was actually looking for one to put it back as it was.

Honestly, at this point I'm lost, on one end I see that the pick up point is in front of the sensor on the M60, and the info I'm getting from Stevie C who managed to make this run is confirming to modify the wheel as he did and put it back in place, as it came out, which locates the lobe for the sensor in a different location, at least on my engine.

here is how mine is modified

here is stevie C's

On this picture, you clearly see the pick up point the m60 (red circle) but mine, modified the same way as Stevie C did, I had the pick up point where the yellow circle is, at TDC

If somebody figures this out and can provide pics, I'd greatly appreciate because at this point, I'm clueless.

Thanks guys!

I was able to find a few pictures of an M62 at TDC :) my buddy took his appart for me.

Here they are, with a pic of the Camshaft position, to make sure.

The camshaft location, at TDC :)

Hi 530i,

thanks for your picture.

I have a question. Are you 100% sure that it was at TDC?
The reason I ask this is because when I compare the camshaft lobe locations it seems they don't match mine at TDC.
I don't have my engine right by me so I can't double check on mine but I want to be sure since the pick up for the Camshaft sensor is located in s spot that is going against the other info I found.

If you have any other pics or close ups to make sure, that would be great.

Thanks

Thanks a bunch for the pics.

Question. Do you know what the little nub/dot is on the M62 cam sprocket? I was wondering if that is representative of TDC on the M62 :dunno :help

[TGreene]

These pics will be a huge help as people start doing more M62 swaps.

I still don't totally understand, but I think with the engine in front of me and these pics, I would be able to figure it out.

[naika]

The only concern I currently have about finishing the modification on the M62 wheel is that the pick up point on the M60 wheel seems to be in front of the sensor and if I mod the M62 wheel as it was done in the "M60 to M62 conversion" thread and put it back in place as it came out, the pick up point doesn't seem to be at the same spot.

If anybody has another picture of an M60 wheel at TDC, that may help confirm

Hi naika, yes the crankshaft is at TDC No. 1 cylinder. The cam timing tools are in place, the pin is in the drive plate and as you can see the cam lobes are off the cam followers. Torqued the cam drive sprockets in place and then rotated the crank 720 degrees to check valve to piston clearance. Car has done 46k km since then, 2 years ago.

Thanks 530i for the confirmation.
I did check on the TIS and you're right (sure you already knew that :) )

Then, I think I have all info to put my M62 back together with the M60 engine management.
I'll try to put up pics once it's done, that may be helpful for others converting the M62 to OBD1

hey im dropping a prevanos m62 into my 95 740i (m60). i to had to modify the cam pickup and wanted to just double check, all i have to do i suse the bmw timing tool to make sure cams are at tdc and when they are, just reattach modified pickup plate to gear with the tab corresponding to the pickup hole, is that correct???????

Hey did you ever get those pictures? Did the trigger end up being before, on, or after the camsshaft postion sensor?

[bemmerguy714]

any one?
