1.9l n/a industrial engine/motor

[fck]

So my bottom end on my motor needs to be rebuilt.
while i've been asking around getting quotes and opinions locally,
someone mentioned they've got an industrial motor already rebuilt just laying around, for a decent price.
knowing that generator/forklift motors are designed to work at a much smaller rpm range of use,
what will i need to do to ensure a motor like this would work well with a car?

I'm assuming something needs to be adjusted on the Injection pump to ensure that the rpms don't hang in one place.  different throttle springs?

I'm also assuming that the motor mounts are in the same place, and i can reuse the brand new mounts i just bought for my 1.6?

any resources for these unusual motors?

The engine itself will be pretty much the same as any other VW IDI engine.  Not sure if it would have the oil squirters and everything that other AAZ's had.

Injection pump will most likely not be suitable for automotive use without modification if the engine was being used in a constant RPM application (generator, pump, hydraulic system, etc) - those governors are designed to hold the engine at a constant speed with as little variation as possible, not really what you want for on road use. Generally they're all set up for somewhere around 2000-2500 RPM too, so absolutely no fun in a car.

How's your current pump and injectors?  Assuming they're fine you should be able to bolt up your current pump / mounting bracket / lines / injectors even if they're from a 1.6L, you just need to keep all the pieces together (IE the 1.9L lines don't fit properly on the 1.6L injectors, the mounting brackets for the pumps are different, etc, but those parts will attach to either engine)

[fck]

I've read somewhere (didn't save the thread)
that some sort of return spring or bracket can be swapped from the 1.6 id pump to the 1.9 id pump to make the throttle act as normal?

does this seem logical?

The engine will work fine. I have what used to be an ADG so it has squirters and TDI style crank and pulley.As far as i could tell the difference  in the IP was the governor and 8mm [!] head. I obviously didn't use that pump in my transporter.

[fck]

what pump size did you end up using?
i'm not sure of the size of my own ip.

I might have two of these comming, so please keep the info going.

Everything I've read so far is that these engines are just N.A. AAZs with a load sensing gov. vs a speed gov.

Also I read in a few different spots that there is some out there that have "made in mexico" cast into the blocks. They say that these have different internals, longer rods, longer stroke crank, and pistons with a different rist pin height. (like putting 6'' rods in a 350 chevy). I have a bunch of info saved about them, Think one would be cool to have turboed.

There is no such thing as NA AAZ. 1,9 NA engines have indeed longer (150mm) rods than turbo engines (144mm) Pistons are same 6mm shorter. All 1,9 diesels have oil squirters and stroke is same. Some later NA's have same crank as TDI.

Hey Caveman, was that you I saw gunning a green Transporter onto Curé-Labelle in Ste-Rose
on my way to work the other day? I was kind of nodding off in my car a the light and when
I spotted you I think you turned your head to scope out my black rustfree MKII 1.6D jetta
Still work at the Unimog place ?
This is in my yard on Berlier in the Ind. park.
Gas tank and 1.8 coming out this weekend.
Going to be an AAZ GTI !!

I didn't get my engines yet, didn't even see them. But when asked if I wanted them I said @#$% yea. I was told they were aaz's.

The following Info is what I found on these engines that I thought was interesting so far. This was just copied and pasted to my notebook since I have too many sites saved on the computer already, so I can't give any links. I don't know if it's all correct or not. It would be great to get any info I can on these :

I have an 91 Jetta that came with what is termed an AAZ (industrial) 1.9TD VW engine
( made in Mexico - how do I know? I looked and looked for anything "German" but only found Mexico on the most
upper outer passenger firewall side of engine block right there where the head meets and close to the timing belt ).
 It is the industrial engine because I took the rods (( which are longer ) and pistons ( which are shorter )
 compared to the German AAZ non industrial - engine rods and pistons) out and measured them.
 Now initially the Jetta was an ECO Diesel so the PO just swapped everything over from the 1.6TD onto 1.9TD
 long block. The Jetta seemed to rap out quickly with industrial components - and had modest amount of power with
seemingly a fair amount of torque.
The rods that I want measure out to be 113mm in length between lowest point on wrist pin bearning and upper most
point on rod end cap bearing these come from the Mexican 1.9TD while the German AAZ rod measures 106mm in length.
 The longer rods create a greater stroke making more low end torque and are perfect for like VW pickups.
Also the wrist pins from the Mexican block measure out to be 24mm in diameter a bit smaller than their German
 counter part at 26mm in diameter. The part number on the Mexican engine rods and the one's I am looking for
have UK2 E1 75 SL0 on the rod end cap where as the German ones read UK2 K 24 SL0. Even thought the total
 piston/rod combination is the exact same on both the Mexican engine with the Mahle pistons are shorter to
compensate for their longer rods and them selves read A11 on one skirt and 79V97 on the other skirt where as the
 German Mahle pistons read A301 and 79V101 respectively. As depicted in the pics the Mexican engine rods also have
 in the center running the length a ridge type stiffener/strengthener.

How do you know it was made in Mexico and how do you know it is a 1Y?
My industrial motor made in Mexico has the 24mm wrist pin - 113mm length rods which are not the ones used
in the 1Y engines which have the 26mm WP - 106mm length rods. If yours is a 1Y block then it is a
German industrial engine and this engine code will be on the flat boss spot there just under # 3 glow plug.
 If there is no code on flat boss spot and Mexico is casted onto the back side of block up at the top by the TB
 then it is a Mexican industrial 1.9 - and I cannot say for others but mine had the longer stoke piston set which
equates to more than 10HP over like say the 1Y motors - now since all 1.9 blocks have oil squirters in them - they
are turbo friendly which mine is a TD.

Good to know! I do know that alot of these engines will be avalible do to the emission standards being strict. Any that operate equipment on trucks are being removed and updated. That is were mine came from.

Yeah man, that was me. I'm still there, but not for too much longer. That shop is a constant mess, ridiculous considering it's also a Porsche, BMW etc shop. I can't believe people bring their big $$$ cars there.

[Laurentian]

Caveman, have any extra AAZ parts that could be useful for my
swap for sale ?
Hugh

[fck]

looks like some very good info in this thread

i'm going to go take a look at the motor this weekend (it's a friend of mine's dad's motor, and he's not sure if he wants to sell it or not), what should i do to make sure it's up to snuff? turn it over by hand? how does one accomplish that?

motor is complete with belts and accessories and such, alternator, etc.  woop!
hope the cost is good

I just may be buying a 96 golf for parts, what do you need?

[Laurentian]

Caveman, I'll PM you.
OT : Are the parts sold by TDI-Parts.com any good ?
The AAZ std. piston kit price seems too good to be true..
