Hi Randy.

Thanks for that but struggling to access your account at zeeasylum.com

Is James hosting these on the EAC site somewhere?

How is the fixing of these links going? Anyone have any idea where I can find them...

Until someone hosts the OP's PDFs, these might help.

Hi all.

I hope this lasts for a while. It would be nice to be able to upload these directly onto the site though.
Very special thanks to Jeff for creating and compiling these.

Thanks for posting the links. I've downloaded the files and will work on getting them hosted here.

Great! Last week I bit the bullit and paid a reputable shop to replace all four and the water pump and 3 tensioners 2500 bucks. That included oil change, new plugs, valve cover gaskets etc.. question. Would you treat the car as a new break in? allow things to seat before playing hard with it. its a 99 540i sport 6 spd. with 96k on the clock.

M62 Vanos Timing Chain Guide Replacement Parts List

Vanos timing adjustment instructions

Replacement of Chainguides on M62

[E30User]

I'm looking at the pdf (http://www.bimmerforums.com/wp-conte...uidesonM62.pdf). Something that confuses me about the process is the timing after the guides are replaced. I will have the timing tool kit for this job. If I lock the crank and the cams down before removing the chains, wouldn't that make it so I don't have to worry about the timing, since nothing is shifting? I'm pretty sure I'm misunderstanding something obvious, but clarification would help.

My initial thought on the process was(I'm extremely generalizing here):
-loosen crank(jesus) bolt, but don't fully remove yet
-put crank pulley back on just enough to see TDC marking and turn to TDC
-insert crank locking pin
-remove crank bolt and timing covers
-put on cam lock blocks
At this point, I thought I'd be able to remove chains and replace the guide rails without disturbing the timing. After reading some guides, I seem to be misunderstanding this. Does the timing get compromised when the chains are removed? In the context of this project, I guess I was thinking the tool kit keeps timing in check during the procedure, as opposed to getting things back to spec after the procedure. Still, I'm not too worried about this since the guides are straight forward and I will have the proper tools.

I do plan to do the vanos seals(beisansystems), so I do plan do make use of all the tools regardless. I just wanted to get a better picture in my mind of what's going on. Also, does anyone have any alternative methods for setting the chain tensioner tool to 6in/lb without that special tool? I saw someone using some cans of soda in another diy, but anything other ideas would be appreciated as well.

Yes the timing is compromised you must remove the gears on each cam in order to replace the chain this requires the engine to be re timed with the special BMW tools its not that hard. take your time you do need a continuity tester in order to do this

Thanks for clarifying. Yup, got my multimeter ready.

I have a couple questions:

First, does anyone offer that parts list as a kit?

Second, has anyone managed to change the guides without having to re-time the motor? Local dealer isn't interested in helping and I'm having a hell of a time finding the tools to lend. I'd really rather not spend the money to buy them.

Third, has anyone made a video of this process? It's hard to follow what parts being talked about in some of the pictures.

[CABimmer]

There are lists published on bfc.com, you can rent all the tools you need. It is impossible to do the guides and not time the motor. If you follow the directions, you can do this job. It is very time consuming, but not that hard. I dont know if a video, as the job takes 20+ hours

[makenzie71]

No I have the list of parts...what I mean is there anyone who carries the list as a single part number. Handing over a list of 15 twelve-digit part numbers there's a lot of opportunity for you to not get all your parts or possibly get the wrong parts.

I suppose if there is no video, there will be when I'm done.

Just a heads up:

I had quite a few malicious programs installed on my PC last night after having downloaded the PDF's from this thread. Just an FYI. It was easy to deal with but make sure your spyware/virus software is up to date. I'm not sure yet which file came with the hitch hikers yet.

- - - Updated - - -

One more thing I wish to clarify...what I meant by "without timing the engine" wasn't that I want to just slap it all together and hope for the best. With other engines I have simply marked and locked the cam and crank positions and reassembled with them in the same locations. As we can only go one way or another a link in the chain I thought it might be much the same situation here, but I can see it not being so simple. I was just curious.

[rf900rkw]

People have tried to do it by marking the parts. I suppose it would be possible *IF* you can get the chain off without loosening the cam sprocket bolts. There is no indexing from sprocket to cam, bolt tension only holds things together. And the intake cam flops around 40 degrees inside the vanos unit, so you can not reference the cam only.

But.... if I was going through the trouble of chain rails, I would be replacing the chain itself and rebuilding the vanos units. Retiming would be an absolute must.

[makenzie71]

What prevents getting the chain off without loosening the sprockets? Is there not enough slack in it to do it with the tensioner removed?

Not that I'm set on making the attempt...I simply like knowing all of the options.

[rf900rkw]

That I can't answer, having never tried it. The left and center rails are designed such that the chain has to be removed before the rail. But the right rail, the tensioning side, may give enough slack when pivoted over.

[240sxguy]

You can get the chain off without removing the cam pulleys, but you sure as heck can't get it back on... I tried.

I jacked around with some cheap knockoff timing tool set from ebay for a few days before I gave up and rented from OEMbimmertools. I wish I had done this to begin with.

[CABimmer]

They dont cost that much to rent, just rent them and do it right.
