Crankshaft Pulley

1

Does anyone currently have a crankshaft pulley removed from an engine?

I need the diameter over the flanges of the innermost (alternator belt) pulley.

I want to set up a 350 mark for timing at 3000 RPM.  A search of the Internet suggests that this is a far more reliable point for timing with a strobe than the idle RPM point and moreover much more easily read.

Thanks

Les

Les the easy way is to measure two inches exactly from the 5 degree "V" notch clockwise. This will give you 40 degrees all in at 3k rpm. I have done this and checked back to back with the VW way and it gives EXACTLY the same reading. Greg E

Les. and All, am at Narromine, went first with doka when it refused to go, limped home after 65 km. every 5 mins or so I had to switch the ignition off and on that way it got me home. Could it be the ecu?
Yes I have a pulley off but. will be home by Friday only. I can help you then. 
Btw I had to take Elkes Polo to get here
What a delight to travel 700 km on a bit over half a tank diesel .....

Done it the same Greg and checked with Snap On digital t light , gave me
39 deg happy with that

Greg,

I got the 35 degree figure from here: http://www.gowesty.com/library_article.php?id=1607

Would you have a look at that and tell me what you think.  Since I don’t have an ECU timing plot, I have no way of knowing if the 35 degree figure is accurate for 3000 RPM and an additional 5 degrees of advance could be significant.

Nothing wrong with what they are saying Les. The spec for the MV is 35 degrees +/-5 degrees @ 3k. In my experience going the full forty will give you a bit more pep and with the low comp ratio (mv) and running high octane fuel the likelihood of detonation is non existent.
Spec is on 28.41 Bentley.

Greg,

Thanks for that.  I will have to install a tacho – been going to do it for years! – so that I can establish the 3000 RPM point.

Les you only have to be above 3000rpm (engine hot). So you should be able to slowly increase the engine speed and see your new mark getting closer to the case halves. From 3000rpm your new timing mark will go "stationary" and hopefully line up with the case halves. I always then double check using the vw method.

Les,
Maybe you missed seeing the GoWesty ignition timing decal for MV T3s, it gives the distance around the pulley for 35 degree position. Click on the pic and it will enlarge for easier viewing.

Perhaps a bulk purchase of this decal is in order!? Looks a handy permanent reminder for DIYers and/or mechanics.
Cheers.

Its simple if you've got a timing light where you dial in the amount of advance required , but should also be as simple as splitting the pulley into 5 or 10deg increments . Remember high school maths? Or maybe a little plastic protractor. Eddie.

Ken,

Very well spotted!!

This is a diagrammatic representation of what Greg posted.

I am glad to see that Go-Westy is as scathing of the Bentleys ‘manual’ as I am. Bentleys is, in many instances, a horrible mishmash of illogic; this is a very good example of it.

If anyone thinks that I am being critical, I certainly am but from a rather strong base. I spent five years as an engineer author, mainly writing missions systems manuals for the RAAF; the required standards were high the Bentleys standard would be a long way off the low end of the scale. (Since I am bound by the Official Secrets Act, I can’t be more specific about what I did.)

From Greg’s information, I could see that each 50 equalled ¼ inch and I will be marking my pulley accordingly. I am quite pissed off that Bentleys didn’t mention the 3000 RPM setting. As Greg pointed out, the ECU is hunting at the +5 point and the strobe therefore shows dithering, whilst it is stable at 3000 RPM.

Anomalies!!

On reviewing the new information, I find that there is a serious anomaly in the GoWesty information. 

In the text, they say that the notch in the inner flange of the fan pulley is NOT TDC; TDC is the shallow depression on the outer flange of the alternator pulley and to the left of the notch.

In the illustration of the sticker, they show the notch as TDC.  This contradicts the text!

Throughout Bentleys, the notch is described as a “timing mark”, not TDC.  On page 28.41, the depression on the outer flange is shown in the illustration but not identified.

It is probably safe to accept that the depression is in fact TDC but I would like some confirmation from someone who has direct experience.

Hi Les,
Looks like GoWesty needs to do a makeover of their description AND their decal ... it's all somewhat ambiguous/unclear.
Still, having this pointed out and now the wiser, we can hopefully all move on with a clearer understanding.

Les, I've yet to check my ignition timing, something I've been wanting to do but not felt confident about the procedure. I do own a standard timing light with built-in tacho but not a later model with the dialer. If after completing your ignition timing adjustment using the 35 degree @ 3000rpm method, I'd appreciate your posting to this forum any thoughts on your procedural steps and pitfalls, if any. Thanks.

Ken,

I have emailed GoWesty to draw their attention to the conflict of information.

My timing light is just plain vanilla and I don’t have a tacho so I will buy one and set it up before I get back to the timing.

Before that, I will permanently mark the fan pulley at 350.

Les and all,
So, I've had a go at adjusting my ignition timing as per GoWesty decal spec - (warmed up motor, newly marked 35 degree setting @ 3000rpm), then using a timing light, adjusted distributor body clockwise to achieve new pulley mark steady at TDC). Then took van for a test run. Found the motor responsiveness to now be quite gutless. So back to the drawing board. Not at all sure how to proceed/experiment further other than returning the distributor body back to or near its original setting.
Anyone else had a similar experience? Or did I go wrong somewhere with this procedure?
Cheers.
Ken

if you've lost respsoniveness and power by changing the timing, and no other changes...
the timing is not advanced enough.
( for the fun of it, you should make sure your timing advances when you rev it. The ECU controls that so it's highly likely to be advancing when you rev it. )

Unless 'other things' are messed up ...
this basically works.
Advance the timing ( turn dist counter-clockwise ) ..in this case I'd start with 1/4th of an inch at the dist outer edge..
drive it.
try to make it ping by giving it a lot of throttle at lowish rpm.
if you can make it ping ...the timing is too advanced.
when you get to where it responds well and you can't make it ping ..
back off the timing just a little and you'll be close.

there is another back yard method that can work ..
BUT ....idle factors MUST be working ...
which are ..
throttle switch must be making contact at idle ( can't begin to express how many dozens , hundreds even, I've found not working )
thottle body has to be working right.
if you idle rpm does not change in a fairly linear manner when you turn that large air screw ( a little less than 1/2 inch in diameter ) ..in is slower ..
if it does not repsond there .....for whatever reason ....throttle body itself, air leaks, Air Idle Control Valve not working ..
control unit for it not working < common > ..
then you can't do this back yard timing adjustment, which works amazingly well.

if it's warmed up and idles right ..
with engine running turn dist counterclockwise advancing timing ..it'll idle faster and faster as you turn ..
when you get to where it doesn't speed up the idle ..stop turning it any further that direction...
that's probably 40 degree advance or something extreme like that ..

then turn it the other way until it almost stalls ...where it's very retarded.
turn back and forth a few times between 'that's way advanced and that's way retarded' ..
then put the dist right in the middle of those two extremes.

adjust idle, go for a test drive.
Again ..basically 'everything' has to be working right to do this effectively ..
good injectors, good Temp Sensor II ..
good Air Flow Meter ...good fuel pressure and FP regulator
etc. etc.
and good plugs and wires. If plug wires are old or cheap, they are suspect.

have fun !

Hi Scott,
Thanks a lot for these trialling procedures described ... definitely worth a go, even if for no other reason than getting some hands-on distributor function experimental time.

A couple of other queries to make on this topic please.

I know the pulley TDC mark is correct because its "groove" is at centre split case position when rotor is pointing at No.1 cylinder so ....
Have you ever seen a T3 (Vanagon) triple drive pulley that only has the TDC "groove"? If not, that's how mine is. No sign at all of the "notch" for 5 degrees BTDC. Is such a pulley with a missing 5 degree "notch" unusual?

If for say just experimental reasons I swap out my present distributor for the "rebuilt by Bosch" spare I now have ... see same at http://www.van-cafe.com/home/van_1223689737929/page_612_1153/distributor-bosch.html, is this a simple straightforward swap procedure, ensuring first the rotor is pointing in the same direction as the old distributor removed, to help engage the distributor clutch into the offset keyway of the driveshaft? If it's that simple, then I assume I can then continue on with trialling the setup procedures you described. Or have I missed something else with this changeover? Thankyou.
Cheers.
Ken

if you've lost respsoniveness and power by changing the timing, and no other changes...
the timing is not advanced enough.
( for the fun of it, you should make sure your timing advances when you rev it. The ECU controls that so it's highly likely to be advancing when you rev it. )

Unless 'other things' are messed up ...
this basically works.
Advance the timing ( turn dist counter-clockwise ) ..in this case I'd start with 1/4th of an inch at the dist outer edge..
drive it.
try to make it ping by giving it a lot of throttle at lowish rpm.
if you can make it ping ...the timing is too advanced.
when you get to where it responds well and you can't make it ping ..
back off the timing just a little and you'll be close.

there is another back yard method that can work ..
BUT ....idle factors MUST be working ...
which are ..
throttle switch must be making contact at idle ( can't begin to express how many dozens , hundreds even, I've found not working )
thottle body has to be working right.
if you idle rpm does not change in a fairly linear manner when you turn that large air screw ( a little less than 1/2 inch in diameter ) ..in is slower ..
if it does not repsond there .....for whatever reason ....throttle body itself, air leaks, Air Idle Control Valve not working ..
control unit for it not working < common > ..
then you can't do this back yard timing adjustment, which works amazingly well.

if it's warmed up and idles right ..
with engine running turn dist counterclockwise advancing timing ..it'll idle faster and faster as you turn ..
when you get to where it doesn't speed up the idle ..stop turning it any further that direction...
that's probably 40 degree advance or something extreme like that ..

then turn it the other way until it almost stalls ...where it's very retarded.
turn back and forth a few times between 'that's way advanced and that's way retarded' ..
then put the dist right in the middle of those two extremes.

adjust idle, go for a test drive.
Again ..basically 'everything' has to be working right to do this effectively ..
good injectors, good Temp Sensor II ..
good Air Flow Meter ...good fuel pressure and FP regulator
etc. etc.
and good plugs and wires. If plug wires are old or cheap, they are suspect.

have fun !

Les and all,
So, I've had a go at adjusting my ignition timing as per GoWesty decal spec - (warmed up motor, newly marked 35 degree setting @ 3000rpm), then using a timing light, adjusted distributor body clockwise to achieve new pulley mark steady at TDC). Then took van for a test run. Found the motor responsiveness to now be quite gutless. So back to the drawing board. Not at all sure how to proceed/experiment further other than returning the distributor body back to or near its original setting.
Anyone else had a similar experience? Or did I go wrong somewhere with this procedure?
Cheers.

Ken,

I have emailed GoWesty to draw their attention to the conflict of information.

My timing light is just plain vanilla and I don’t have a tacho so I will buy one and set it up before I get back to the timing.

Before that, I will permanently mark the fan pulley at 350.

Hi Les,

Looks like GoWesty needs to do a makeover of their description AND their decal ... it's all somewhat ambiguous/unclear.

Still, having this pointed out and now the wiser, we can hopefully all move on with a clearer understanding.

 

Les, I've yet to check my ignition timing, something I've been wanting to do but not felt confident about the procedure. I do own a standard timing light with built-in tacho but not a later model with the dialer. If after completing your ignition timing adjustment using the 35 degree @ 3000rpm method, I'd appreciate your posting to this forum any thoughts on your procedural steps and pitfalls, if any. Thanks.

Ken,

If you don't want your old dizzy - I need one - I bought a 2wd Caravelle last weekend and its missing the following:

Drivers side head

Air box + AFM

Distributor

Alternator

Otherwise complete but apparently has a problem with the drivers side connecting rod bearing as it was noisy when running over 5 years ago.

Motor still turns over and has good compression to the passenger side head.

If anyone has any spare bits - let me know - I would love to get this thing running.

Thanks and cheers,

Skot

Hi Scott,
Thanks a lot for these trialling procedures described ... definitely worth a go, even if for no other reason than getting some hands-on distributor function experimental time.

A couple of other queries to make on this topic please.

I know the pulley TDC mark is correct because its "groove" is at centre split case position when rotor is pointing at No.1 cylinder so ....
Have you ever seen a T3 (Vanagon) triple drive pulley that only has the TDC "groove"? If not, that's how mine is. No sign at all of the "notch" for 5 degrees BTDC. Is such a pulley with a missing 5 degree "notch" unusual?

If for say just experimental reasons I swap out my present distributor for the "rebuilt by Bosch" spare I now have ... see same at http://www.van-cafe.com/home/van_1223689737929/page_612_1153/distributor-bosch.html, is this a simple straightforward swap procedure, ensuring first the rotor is pointing in the same direction as the old distributor removed, to help engage the distributor clutch into the offset keyway of the driveshaft? If it's that simple, then I assume I can then continue on with trialling the setup procedures you described. Or have I missed something else with this changeover? Thankyou.
Cheers.
Ken

on the crank pulleys ..3 triple groove cast iron ones ..
there are two types...( shown in Bentley I believe ) .one for 1.9 waterboxer engines ( in the US anyway ) and the one for the 2.1.
Been a while since I laid my eyes on one....but all that I have seen have two marks.
the inner mark is to the right of the outer one on a 2.1 crank pulley , about 3/8ths of an inch.

that's the right dist at Van Cafe .

just position the engine on # 1 TDC ,,,
mark or note the relative position of the distributor body, then,
remove the distributor carefully.
*never* rotate the engine over with dist removed * !

if you have to rotate the dist left/right a little to remove it ..no big deal.

install the new dist with your fingers turning the rotor slightly ..
it will 'almost sort of' fit in 180 degrees out .

when it's right ..it'll drop down in solidly.
