Don't try it without removing the tandem pump. It's not that hard, make sure you have a new tandem pump gasket and all new bolts for the bearing caps.

It can be done

Replacing the camshaft without removing the tandem pump can be done, as that is the way I did it with mine. Search this forum for posts by Frank06 and others for a great deal of useful information about cams.

Briefly, what you have to do is first position the engine at TDC, remove the belt, rotate the crankshaft backwards 90 degrees to keep all the pistons out of the way of the valves, then rotate the camshaft 90 degrees clockwise so the tandem pump slot is oriented vertically and there is minimal valve spring upward force on the #4 cylinder. This will mean that both #1 cylinder cam lobes point to the front of the car. The camshaft can be both removed and installed safely without damaging anything if it is in this position.

I think they whole procedure is on the board here in a post somewhere, but I cannot locate it right now. I have the complete, detailed instructions from Franko6 because I bought all the parts for the job from him, but as it is his written work and not mine, I do not feel at liberty to post them.

Hi thank u does this work for any 1.9tdi engine?

Mine is a BRM engine. I think it might be the same for a BEW, but I really have no idea. I am not a professional mechanic. I just studied my BRM Jetta enough to do the work myself, and can report from first hand experience on only that.

I did mine without removing the TP


- set the engine to TDC using crank index tool
- moved crank counterclockwise 90 deg so all pistons are in the middle of their strokes.
- removed belt
- spun camshaft until "slot" joining it to the TP was vertical (no piston impact because all pistons are mid way in the cylinders right?)
- removed all fastners holding cam
- cam should be free by pulling from the top

Install is pretty much reverse of the steps.

I have the Cam tools and timing belt tools that I will give you a good deal on if you need them. I don't have my car anymore so I don't need them.

BEW, BRM and BHW are all the same. Personally, I would remove the tandem pump to 1. make the job easier and 2. the TP gaskets are probe to leak and in turn take out the temp sensor housing. Also, I would replace the timing belt and water pump while in there. It's not a lot of money for the parts and you basically get to reset everything to 0 at the same time.

Also, if it is a BRM, and you are tempted to go with the cheaper BEW cam, just know that there will be a noticeable power drop from the BRM to the BEW cam

I going to replace cambelt and waterpump along camshaft the question is do I have to do the camshaft first then put new belt or do the belt fist then then camshaft or it doesn't matter

Correct me if I am wrong
Place the crank on Tdc lock it
Take the belt off then
Remove the crank lock
Then turn the crank counterclockwise quarter turn... While the belts off
Or set the crank and camshaft into Tdc then turn the crank quarter turn counterclockwise so the position of the crank and camshaft not Tdc any more
In that position remove the belt and everything else then fit the camshaft in the same position as it was on removal and fit everything back...
Can I do the injector adjustment by turning the camshaft clockwise and anticlockwise while the belt not fitted and crank is not in Tdc?
Or I have to refit the belt first then make sure of Tdc position then adjust the injector by turning the crank?

Here is a link for cam replacement over at myturbodiesel, complete with videos.

https://www.myturbodiesel.com/wiki/c...tdi-pd-engine/

Replace the cambelt otherwise you’ll be back in 40k miles doing a belt job, and you already have the engine apart.

I would remove the tandem pump. On a BEW engine there are 3 13mm bolts holding it on. I replaced mine without removing the pump and it only increases the complication factor, and I had a leaking pump gasket afterwords so after I had the job completely done I still had to remove the pump and replace the gasket.

For the $10 or so it’s worth it to become a premium member at myturbodiesel so you can see the second part of the write up.

It should not make a difference, because the belt removal process its just a matter of loosening the tensioner and pulling the belt. There should be no need to spin the crank.

Positioning the crank 90 deg ccw allows you to spin the cam at your convenience such as when setting inj lash.

I also recommend replacing t-belt and associated hardware while there.

As for the remove/do not remove the tp, if you go for not removing it, make sure the gasket is not leaking oil into the driver side of the engine. Otherway its a good timw to replace it.

If its your first time replacing the cam, grab an extra cam seal. They are easy to damage when inserting in the cam snout.

Please observe the general guidelines
* if tbelt is mounted and torqued and need to spin the cam/crank ALWAYS spin BY THE CRANK.
* once the belt is removed and the pistons parked midway (by the 90 deg ccw) you can spin the cam by its hub.
* please observe all torque sequences and specs for the different fasteners.

The myturbodiesel videls are golden and i also recommend paying the full membership. They are worth gold for the non professional mechanic.

Thanks my engine is bxe... Do they are different as it looks the same the1 in video? Another question while belts off and turn the crank quarter turn ccw to do injector adjustment by turning the cam with hub.. Does tandom pump have to fitted b4 adjustment or can fitted after the adjust the injector?

The tandem pump is not in time with anything on the engine. So it can be done afterward. BXE,BEW, BRM I think are all similar so it shouldn't make a difference. I saw you were from the UK so I was wondering what engine you might have.


However I have never seen a BXE engine so maybe someone with more knowledge will chime in on that part of your question.
