New diesel owner, swapping a 1.5 into my rabbit GTI.

[vdubspeed]

Well I made a little progress today.

First of all, this car has no HVAC at all (I used to race it), and it has no power brakes. For this reason I do not need and type of vacuum signal. So...for this segment I deleted the vacuum pump and here's how it went.

I pulled the vacuum pump out like every other 8V or 16V there needs to be a gear there to turn the oil pump off of the intermediate shaft. Great I thought...I have an old 1.8 16V out back...I'll just steal the gear and cap and be done with it. Negative.

First off all the 16V pump shaft is splined. The diesel oil pump is slotted. So I thought....I just switch out the pumps. No can do...the intermediate shaft gear is cut opposite of the diesel so I would have had to switch that to. At that point...I needed a new plan.

Now I had thought about cutting the vac pump but didn't want to because it worked good. Oh well...f-it. Pulled out the chop saw and cut it right above gear BUT leaving the center shaft still pinned in there. This will allow the intermediate shaft gear to still turn the oil pump.

Next I had the 16V cap which needed lathed down. A quick trip down to the machine shop and I was good to go. Taking the overall distance from the 16V cap and gear....the diesel gear was machined to a nice flat surface and the 16V cap was machined down too.

Here's a before shot. Cut vacuum pump gear/shaft on left. 16V gear in the middle. 16V cap on the right.


Here's the finished product.


As you can see the diesel gear was machined to a nice flat surface and meat was taken off the cap. When I got home I bolted it down and as I torqued down the cap the intermediate shaft binded. Damn it....didn't take enough meat off. Well...using a shim from an type 1 generator, I tucked it under the cap and cranked the cap/bolt down. no binding.

Vacuum delete a success.

Thanks for viewing,
