Bit Missing (Pump Timing)E D I T

Post by peteabbott »

My appologies if I am asking in the wrong place BUT I am short of a Injection Pump Pulley for my 1Y, just the pulley as the driveplate is bolted to the pumpshaft but I am short of the toothed pulley that bolts to this with 3 bolts. Thankyou

Hi Pete sorry to hear about your woes mate dont have a spare pulley but my only sugestion is find your nearest Seat dealer and if they are anything like mine you will find them very helpfull, on no accounts go to VW (dont want to know) only other option is go looking in a breakers yard, look for a Seat Cordoba, an Ibiza or the golf Mk3, But the biggest problem you will have is if the centre bolt has been undone or loosened if it has your pump timming has gone, Then the pump will have to be setup by a diesel specialist centre, dont really matter were the pulley locates on the three bolts when fitting. any problems or questions just e-mail me or pm me----------- :ok

thread resurection because i think i've made a boo boo reason below if it makes sence to anyone, the thread i have put on brickyard

http://www.brick-yard.co.uk/forum/diese ... 63046.html" onclick="window.open(this.href);return false;

the same question

chaps had some issues with my 1.9 1y motor which ended up with my headgasket blowing

anyway fitted that lot but...................what i did before stripping the head off etc was a bit dumb of me, pressure of it being my daily rushing a job when i should have, what i did was line up my marks on my timing belt & engine block but forgot that the crank pulley should be at TDC (dumb "bar-steward")
anyhoo, got that all sorted but i think my diesel pump is now out of sync if that makes sence?????

my engine wont now fire up

now the diesel pump, should that be set in a specific postion? i know you can fiddle with the pump timing by loosening the 3 nuts on the diesel pump pulley but............

what i mean if it makes any sence to anyone is the actual mechanism of the pump itself, should that be in a specificly set position when the crank, cam & flywheel are in their rightfull position

or am i completely of the boil, i remeber reading somewhere that someone had a pump issue where they needed a new pump & the place/chap that reconditioned the pump had to "RE-INDEX" the pumpthen when the person fitted the new pump it was the 3 nuts on the pulley wheel they had to fiddle with to get thie bus to run correctly

hope you chaps can help, i need to get my daily crewcab running again desparately!!!!!!!
All 5ft1" of me lol, big man lil bus lol or the other way around lol :O/ :OP lol

if your in the redline lol ya having a good time! lol ;P

This may help mate
http://forum.club8090.co.uk/viewtopic.php?f=12&t=78122" onclick="window.open(this.href);return false;

Just to refresh....
No.1 piston TDC
Camshaft "locked" at the far end with ya bit of flat bar,(both No.1 valves closed ie both cam lobes sticking up)
Aligning hole through injection pump pulley.
Belt on, tensioned, remove all locking pins and bars.
Spanner the engine over a few times and recheck all your marks.

OR if you want to retime from scratch look at my previous posts.
Seemples !

good luck mate, summer is coming.

i think i'm gonna have to re-time the pump from scratch as i messed with the pump pulley wheel big nut that holds the pulley on!!!!

all is aligned as per your post & i've spannered it over & nothing is catching!

i've been trying to sort this issue since that cold snap we had a few weeks back but the cold/damp & getting soaked doe'nt help with concentration!

i believe i've bolloxed the position of the diesel pump spindle position so need to start from scratch as though the pump & pulley have been apart!!!!!

hope that makes sence!

i have leanrt somthing though, when the pump has been running nicely, leave it the fck alone!!!!! :ok

i have my bentley manual,a golf diesel haynes manual, mostly for the diesel part!

& threads on here & brickyrd to read, damn i'm kicking myself in one way & learning for my own benefit in another-thats called KARMA or somthing is'nt it lol

its ok cause i already know i'm an idiot :idea

You can get the proper job with a purpose made DTI, but all you need to do is clamp your DTI post to something solid, I removed my magnetic base (threaded) and I think I then used the threaded bit to bolt through the throttle bracket.
Anyway here comes a refresher..................
Camshaft locked
No.1 piston TDC
Now you say you moved your pump pulley, have you got the setup where to alter your timing you have to move your whole pump on three slotted bolt holes OR the pulley moves on the pump backplate with three slotted bolt holes.
Anyway with your DTI firmly secured and in the center hole of the injector pipes as you turn the pulley you will see the needle rise and fall (will do this four times on one revolution) NOW YOU WILL NEED TO USE the existing timimg mark as although it is not timed correctly this is the best start point. You dont want to time your engine on the wrong pump position as you could be quarter or half turn out i.e "squirting the wrong injector on the wrong piston" As you turn your pump pulley you will see the needle rise as you approach your timing mark NOW turn the pulley backwards and just where the needle stops rising or falling set your guage to zero. now turn your pulley carefully clockwise until the guage reads 0.98mm.Be very fussy over this and MARK EVERYTHING HERE !
Now you can fit your belt............spanner over the engine a couple of times and recheck all your marks. You can at this point with your guage still rigged up and your belt on check that at TDC your guage reads 0.98mm and also that your camshaft is in the correct position too. You can then if you dont have 0.98mm at TDC adjust your pump or pulley.....and I say again check and recheck as it is not nearly right it has to be right.
Hope I have explained it clearly enough, just take your time, check and recheck........ good luck.

so i dont nee the adaptor pete? i can just my dial guage touching whatever that thing is in the centre of the pump,i'mgoing to check double check & triplecheck all the parametersthat need to be checked beforeputting the dial gauge on tomorrow! ie tdc etc etc
allways appreciated pete!!!!

just managed to get roun to attempt fixing this prob on my diesel anyhoo

where i'm at!

my pump on my diesel is the type that you adjust with the 3 bolts on the slotted pump pulley wheel!!!!!

cam is setup spot on with feeler gauges either side under the feet of the cam locking tool!

piston number one is dead on TDC - checked properly cause i took the cylinder head off for a look, overkill maybe but i know for defo


right then onto the pump

so with the gauge fitted do i get the initial 0.98 setting with the belt off?????


i've been fiddling & got it to 0.92 with the belt fitted, what i dont understand is can i???? or can i not make adjustments to the pump timing with the belt fitted???? if so how do i turn it???

& do put the pump locking tool in to make my adjustments or not - what i mean sort of :? is its a toothed belt so when you looosen the 3 bolts it dont blummin move without the crank moving!!! the cam i can loosen the pulley so it just spins to make adjustments

also i'm confusing myself all the time which way i turn the pump pulley to advance the timing or retard the timing when i loosen the 3 bolts :oops:

so as the motor stands at the moment its at:

crank/piston number 1 at TDC
cam- spot on with use of feeler gauges under the locking tool feet
current pump reading 0.92

i would like to get 0.98!!! :ok

also i dont actually know what the factory setting is or is it meant to be 0.98, i've heard aslong as its in the 0.83-1.07 range but that could be complete bolllox lol

calm down, calm down. You are doing really well mate. I thought the pump setting was between 0.85 and 1.00mm ideally 0.98 so it sounds as though you are there. If you have your pump set right with all the other "bits" in the right place why do you still need to adjust your pump pulley ? If you do need to adjust it, it will be only by half a tooth when you go to fit the belt and at this point as long as things are still locked, moving the pulley on the three bolts and leaving the pump locked where it is should not be a problem. Advance and Retard...........why do you need to know this ?
Top dead center...........check
Camshaft correct.........check
Pump set...................check
If you cannot find the marks on the flywheel then you accurately marked the pulley at TDC yes ?

Everything is in the right place then yes ?
Belt on and tensioned.
Now with your pump guage still attatched spanner the engine over with all the locking bits off.
Bring the engine over to TDC......check the camshaft position is correct........check the guage reads 0.85 - 1.00mm
You might find that you are a tooth out on your belt so an adjustment may be needed .........
At this point with your belt on, tensioned, camshaft correct, TDC No.1 you can slacken the three bolts and move the pump shaft independently to the pulley and there should be enough room in the slots to get the guage to read correctly. Spanner over a few more times and check, check, check. You don,t really want to look into the advance and retard thing because it is either correct or not correct.

right, got that pete, it was staring me in the face really was'nt it :ok

adjusting the pump is the same method as the cam really, ie set it to the corect place with the pulley loose then lock it up & check alls is where it should be whilst at TDC on numbber 1


only other thing is how do i know if the pump is squirting to number one piston????? or is that basicly what i'm actually setting on the pump when the crank/piston is at TDC number one & cam in correct place?

cheers again

the ball--ache of bleeding the pump again :cry: she will run again & this week it blummin has too

Right, you have a valid point there. As long as you have used the locking pin hole as a starting point you should be OK. The timing hole is on the backplate that the pulley bolts on to and the backplate is keyed to the pumpshaft and therfor will not let you time the pump on the wrong cylinder. Just to be really sure I take it you still have all the injector pipes off and all your timing set and belt on......get ya spanner out again and spanner her over and as long as your pump is still primed you should see not a squirt but a dribble coming out of one of the injector pipe connections on your pump as the engine comes up and over TDC No.1 and you can then see that the injector pipe for No.1 goes to that union. Be very carefull though mate as when you do this check you will need to have the fuel solenoid powered up (open). Nearly there.......check and recheck OR measure twice and cut once, if you see what I mean.
If any member reading this can see a fault in my description please speak up because at 59 and a half I do seem to get things wrong lately oops, must go I need another bloomin wee now :oops:

And oh yeah, priming your pump............rightly or wrongly the way I do it is to remove the top banjo fitting and fill the pump from there.

what i've done is the the keywayonthe pump shaft is lined up with a line that is on the casting on the pump, simular to the line thats on the older type pumps

then on the pump pulley there is the grey colored part with the slot in it where the locking pin go's that bolts to the pump spindle, i lined up the slot on that inner grey part of the pulley with the keyway in the pump spindle

then put the toothed part of the pulley on that grey inner part & bolted it down with the 3 bolts

i'm priming the pump tomorrow & maybe get to the point of turning it over i hope i can make it start!

my injector pipes are on but i'm taking them off tomorrow to try to get that 0.98 timing figure :ok & i'll see if some diesel will dribble out of the damn thing :)

fingers n toes crossed for good news tomorrow i hope
