Well i did exactly what the video said not to do when installing the new IP. (finding TDC) (top dead center)

I turned the motor over counter clockwise without realizing and now the IP gear keyway slot is in the 9 o'clock postion and i need it about 7 o'clock to line up with the key on the injection pump i gots.

I don't understand this whole or deal....the video said if you try to find TDC by rotating engine CCW that it'd mess timing up, Is that because of gear lash?? How do i correct this once i get it to go clockwise?? pull the timing case cover ?

Is the engine at TDC everytime you shut it off?? i don't understand how you can do this without turning the INJECTION PUMP shaft to get the keyway to line up.


Thanks for any help,
Brandon

The only thing I can offer is if you can't muscle the engine in the correct direction with the belt you can drop the starter and with a large screw driver or bar, CAREFULLY, rotate the engine by engaging the ring gear with the bar. You can rotate it in this fashion but you'll need a person on top to advise you that you're moving in the correct direction and also to tell you when to stop.

Remember to pull the battery connections first!

It's metric Brandon...

Im thinkin 15mm. When i started tearing my engine down for rebuild.

I got it turning clockwise, via 15mm socket on the crank. w/ratchet

But do i still need to get it at TDC ? What happens when its at TDC and the IP gear keyway doesn't line up with the position of the key on the injection pump shaft...thats what i don't understnad

What i'm getting at is, in the video the IP is BRAND NEW and is locked in the position where its at TDC and everything lines up perfect. My IP is not, its used and engine was not at TDC when it was removed

So i should just rotate the engine clockwise until the IP gear keyway is lined up where the IP will go on???

Not a problem Brandon, just rotate the pump shaft. As long as the gear isn't moved (and can't if the front case is on), just rotate the pump's key untill it's right or close (you can rotate it in the slots once it's engaged to line up your timing )and throw it on. Thats what I did. Don't worry about TDC and all that. If the gear stays in the gear train, there is nothing to screw up... it IS nice to have the keyway facing up so it doesn't fall out, but maybe a drop of Loctite on the woodruff key in the pump, let it dry, then put it in if the keyway is facing down. Make sure to angle the keyway a little so it starts in without getting hung up though!

Thats what i needed....but the IP gear DOES TURN when you turn the engine over... just turns at a slower rate then your turning it with the ratchet.

So you think by turning the engine over counter clockwise SLIGHTLY on accident, that i messed up timing? or are you saying IT CAN'T as long as the IP gear is touching whatever gear it touches...the video makes it sound like its gonna jump a tooth if i turn the engine over counter clockwise.

Guess i'll just put it back together like you said and if it don't run right (which it won't because i messed up throttle indexing too and took a guess)....I'll pull the case cover, kill the KDP and see how i messed up timing if its possible.

My dad said it could be because of how the gear lash is, but i was pretty sure the gears are all straight.

Thanks so much for a clear answer

I doubt you messed up the time, I assume VE Pumps are similar to a VP. If they are you have nothing to work about.

brandon let me know how you make out...

Do you have an engine barring tool? There is an access point to the flywheel behind the downpipe of the exhaust for turning the motor over.

If the gear is turning and didn't jump a tooth your ok.

From what I gather the only reason to have the pump set to tdc and locked is so when the engine is tdc you can take a punch and mark the new pump. ( to make new timming marks )

Thats the way i understand it too..but wasnt sure because i was going by that video and the article on dodgram.org

I think i got it... i loctited the key in the shaft...let it sit overnight done for the night. (even though i have the ip gear key way at 12 o'clock)

go back at it tomorrow.

I'm positive the IP gear did not jump a tooth, the video was just confusing the crap outta me.

Thanks !!

Crossy's son

i understand now. the engine doesn't have to be at TDC to put a used IP on...

can't wait till i go to adjust the valves

i was just going to tell you that. if the gear hasn't been jumped a tooth, just rotate the engine (clockwise, which is standard rotation) til the notch on the gear is in the position it needs to be in for install. if the pump was locked prior to removal, you shouldn't have any timing issues. now, throttle shaft indexing... that's gonna be trial and error
