more supercharger talk

[truckinwagen]

well, I got a bunch more done today.

injection pump on and engine timed.
alternator mounted(just need to get two bolts to finish attaching it)
oil pump on
IM shaft bearings replaced and IM shaft installed
belt routing mocked up.

here are some pics.

my IM bearing tool(thanks to the Home Depot)


the IM shaft installed


this is cool, the 1.8T serp pulley has a notch that lines up with the IM shaft pulley at TDC.
this will make engine timing sooo much easier!


adapter being made to account for the offset difference on the alternator
(it has been completely welded, and reinforced with some plate now)


initial belt mockup


as you can see here, it did not allow for much belt contact with the water pump pulley.
I will fix this by adding a timing belt tensioner at the lower alternator bolt, this will get more contact with the water pump, and allows for tensioning the belt without moving the alternator.



this is how I left the motor today




I need to get a couple bolts to finish installing the alternator, and then measure for the length of the serp belt.
other than that, all I need to do is add oil, hook up the glow plugs and give it fuel.
but I think I will wait on that until it is sitting in the engine bay.

Pretty impressive dude!

[truckinwagen]

its getting there.

[vanbcguy]

Is there a water pump impeller out there for reverse rotation?  Seems like wrapping the outside of the belt around the top of the water pump pulley would work PERFECT, but that would require a water pump that spun the other way...

Aren't you going to have a timing belt cover? That would get in the way unless you poke a little hole in it.

Good work

[Dirtrag2]

great work!! real top notch stuff

[truckinwagen]

about the timing belt cover, I cant find anywhere to get a lower one, and the local dealer says that they are NLA.

I would like a lower cover, but dnt have one to put on it.

as for the upper cover, I have never had anything but problems with them, if I could find one of the later ones with the backing plate that bolts to the engine and the cover that clips on I would run it, but I hate the early style ones, and will probably just run without it.

[truckinwagen]

thanks for that, I'll grab one of those!

this would be the way I would prefer to do it, but I have never found a counter rotating water pump to use.

so for now I will use the TB tensioner.

if you find a counter rotating water pump, let me know!

there is a pump that spins the other way, i forget what it comes off of, but people putting serpentine belts on there gassers use them

[truckinwagen]

that would be cool, but from where?

I'll just say that I thought I had read the exact same thing. Sorry I can't recall what it was from though.

Have you verified that the notch is in fact TDC?

[burn_your_money]

It's too bad about the sounds in the video tindias.

I'm impressed with your engineering.

[truckinwagen]

Have you verified that the notch is in fact TDC?

yes I have, although I will still use the pointer in the bellhousing for actual timing, having something on the same side of the motor as the crank pulley will make turning the motor to TDC alot easier(as I dont have long enough arms to turn the crank and look into the bellhousing hole at the same time)

[burn_your_money]

What I do is put the engine in 4th gear and jack up the drivers side wheel. Then I just rotate the wheel while looking at the pointer.
