I had the pump off my 617 and now I dunno if I am putting it back right.


I set the crankshaft to what I think is 24 ATDC
then turn the pump so that skip tooth matches the timing mark
then stick the pump on where the pump and block are marked.
then prime it all up and run the lines.

crank the starter and I got no joy, what gives?


I must be setting this crank wrong.
So as you are turning the motor clockwise you start to see marks on the balancer, right.
first you come to like 40, 30, 20, 10 ,0 , 10 , 20 , 24 is where I'm at

Is that right?
wtf
getting pretty tired of lifting that sob in and out of there and spilling diesel and oil all over the driveway.

so what's the deal then? Set it to 24 atdc? Did I measure that right on the crank?
When I turned the motor to start there was no smoke at all and no signs of life. But, fuel sure was pumping up to the injectors.

You should at least get white smoke no matter how wrong you put it on. No smoke means no fuel is being injected, I'd think there's still air in the system.

So, if there's some air in the system then none of the injectors will pop? I cracked some lines open at the injector side and diesel came out. Some bubbles too but I at least expected smoke.
Even if fuel is going in on the wrong stroke, right?
I dunno, should I just keep trying to crank that air out?

Well, I fucking stuck the pump on matching all the markings up at the 24btdc. I haven't even tried to drip the timing. I just thought if you matched that shit up at the marks when the motor was cranked to 24 btdc you could at least start the bitch.
I guess I need to look at this stupid ass drip shit.
What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?


Maybe I have the motor cranked around wrong? I thought every fucking time you turned the motor around to 24 btdc that meant the front most cylinder was at 24btdc, right?

I always get confused by this shit. I thought some diesels were ATDC and the combustion chamber was already super fucking hot.
Then people talk about advancing or retarding timing and I get confused again.
Are they always saying advance as in like more advanced in relation to the rotation of the motor or
retarded as in like latter in the rotation.
IDFK I need shit explained to me like I am retard. Takes like 20 fucking times till it is known.

ok,
so I did all this drip shit.
15. Pump the hand pump until fuel is dripping out of the tube at a rate of 1 drop per second. Turn the IP towards or away from the engine to adjust the drip rate. Have a clock next to you to help time the drips.

when I pump the primer I first get a stream of fuel then it subsides to about 1 per sec. Prolly actually quite faster.
So, wtf is the timing near or what?
Maybe I should make a video of what I'm saying.
I still don't under stand this full revolution shit. The crank is turning 360 degrees while the cam turns 360x2? The balancer only has the markings at one spot not 2. As in it is marked off on a 360 scale not a 180 degree scale twice.

The pump spins at half the speed of the engine, so one engine turn is equal to half of a pump turn.

I spaced on this before, you have an '85 engine right? Rack position sensor on the side of the pump? Find the lock port on the side of the pump, turn the pump until you see the little nub in the center of the hole. Then turn the engine to 15 degrees ATDC and install the pump.

Nah, I am using an older pump. I don't really know what the fuck to do right now. I guess I need to pull that bitch out again and look at the timing mark then make sure the motor is turned to 24 btdc and the cam lobes for cylinder are pointing upwards?

I dunno. I thought I set the pump to 24 btdc this morning. And then I did the drip shit which looked to me like 1 drip/sec but this the first I've ever done that.
I just cannot believe there is not a puff of smoke at all. With the motor turning for like 30 sec there should have been quite enough fuel in the cylinders to see some of it burn up. Right? I dunno. I guess it's a rest for today and maybe I can try again tomorrow. This makes like 3 or better days I have fucked with it and prolly like 15-20hrs of getting nothing but frustration and shit.
Hopefully soon I will be learning and running my fucking car cause this shit is played out.

TAKE THE PUMP OFF. ROTATE THE ENGINE 1 REVOLUTION FURTHER. INSTALL PUMP AT 24 DEG. PRIME. RUN. YOU ARE 180 DEG OUT OF TIME. THE ENGINE DOES 2 FULL REVOLUTIONS COMPARED TO TO 1 REVOLUTION OF THE CAM & INJECTION PUMP.

Ed
4 strokes.... Suck, Squeeze, Bang, Boom.... Intake (sucks air in **piston going down), Compression (as the piston comes up to 24 degrees before TDC, you are injecting fuel **piston comming up), expansion (TDC & after otherwise known as the "Power stroke" **piston going down AGAIN), Exhaust (exhaust valve opens & expells gasses **piston going up AGAIN)... So, it takes 2 full revolutions to account for 1 revolution of cam, IP & tachometer. I suspect you are timed 24 BTDC of the EXHAUST stroke.

Ok, like I said I am retard. And you may well be right. You say 1 revolution of the crank shaft is 180 or 360 degrees? The thing I'm saying is that the crankshaft markings are only on there in one place out of 360 degrees. So how in the fuck do I turn 180 degrees to some place were there is no marks at all?
Sorry like I said I am retard and am definitely not trying to start up any fights, just pissed about all the soot I am getting all in my nails and bloody knuckles et cet,
I will take the pump off and be sure the marks are all lined up.
Then I guess the drip timing thing will do some good. Right now I am injecting 24 degrees ABDC is what we think huh.

That's it for right now. We'll just be ready for the ah-ha and success tomorrow.

OK, 1 full crankshaft rotation is 180 degrees of the engine revolution. 2 full rotations of the crankshaft equals 360 degrees of (cam/IP/tach) a revolution. You (I suspect) are 1 rotation(180 degrees of a full revolution) off & injecting during the exhaust upstroke. No worky like that... You must be on the Compression upstroke.

You need to open up the oil filler to check whether #1 piston is on compression or exhaust stroke, when both of the lobes on the cam for #1 piston are "up", as in not pressing down on the valves, it is on the compression stroke.

You need to open up the oil filler to check whether #1 piston is on compression or exhaust stroke, when both of the lobes on the cam for #1 piston are "up", as in not pressing down on the valves, it is on the compression stroke. Then adjust to whatever degrees before tdc you want, (I adjusted mine to 26* btdc, as suggested by Hercules) and you should be good to go.

Well, I swear I am doing it all right but it still won't fire. At least I can smell fuel, I think. I looked at the fucking cam lobes and they were up. Set the crankshaft at the 24 BTDC mark and then aligned the timing markings on the pump and matched the pump to the block.
And this morning ran down the battery again without even a sputter.

I do not fucking get what seems to be wrong.

How fast is it cranking? You may want to charge both battery and use some jumper cables and use both battery's at the same time! I have an air leak on my euro wagon and it wont start unless I pump the primer pump while I'm cranking it over!

4 strokes engine means 2 full turns of the crank to back at a compression stroke

180* out is one full turn of the crank or 360deg! one stroke = 2 full 360deg turns confusing right?

Haha I'm glad it was you not me </kidding!> --really, I feel your pain. I've just spent three hours trying to get the driver's side console electric window switch back together after cleaning a 27-year accumulation of grime out. No matter how I assemble it, it always works flawlessly on both the front and rear windows when it's out of the console, but the rear window fails to open once I put the switch, ashtray, and console all back together. No matter what combination of ball bearings, copper contacts, orientation of the copper contacts, and rocker I use. I just gave up for the night after about the fiftieth try. A miniature version of your same frustration drama.

My car really only gets attention to things that are relatively critical to operation and safety. Or things that will cause no frustration.

Well now I need to fix the exhaust. My turn down just ripped off. So the pipe is just cradled by my last few feet of rusty steel wire right by the diff.

All that hot air needs to get further back.

Mine is like literally straight. after the downpipe there is a connector with 2 bolts. That's where I cut off the resonator, bends, and muffler and then inserted 4 ft pipe. Had a turn down but like I said it's gone. I think though it might be even cooler without that turn. Just need to get those hot gasses back a little more. As it is now they are pointing right at that tub where the spare tire is. Pretty soon it will melt that under coating. Need to get on this repair and find a better way to hang the whole rig.

Yeah I don't understand why there are so many turns and stuff there in the first place. If I could find some pipe long enough I might consider doing the same thing, even just keeping the stock diameter. It definitely runs much better now though. The turn down tip mostly just helps with sound and smoke I think, I've read without it the back of the car can get all sooty and stuff, but in your case you might need one. Or maybe just make the pipe longer so it sticks all the way out the back haha

I saw some pipe on fleabay in either 4ft or 5ft for pretty cheap. That's where I got my 4ft piece. But I think you'd need like 6ft+ to make it straight all the way to the bumper.
I wish i had a shorty exhaust I could switch on for off roading. A bunch of gravel is what pulled the old rig apart. Had a dude in the back seat, like 2-300lbs tools in the trunk and trimmed rear springs.

A diesel doesn't fire by compressing fuel, it fires by injecting fuel into the hot air! thats why its ATDC when youre doing it by locking the pump
