Author Topic: LDA pump cover rebuild (Read 2888 times)

Luckypabst · « **on:** March 01, 2008, 05:20:32 pm »

I'm looking for a little direction here -

The short story is that I had to replace my leaky turbo IP a bit over a year ago. The pump they sent me was non-turbo and I was in a bind, had to use it. Luckily I kept the core and have it kicking around still. Now I'm ready to swap the LDA on and be back to my astounding power levels of yore.

The whole reason I even replaced the pump (already made a successful re-seal) was the cover started leaking around the throttle lever - disassembly revealed a heavily worn shaft and egg'd out bore.

I need to find a place that can repair the damaged bore - I plan on using the throttle shaft (levers, too) from the existing good, rebuilt pump. I am aware of the "stop pin mod" needed with the NA pump. Hopefully I can get around that with the pump installed.

Any recommendations on where to start to have just the LDA cover tidied up?

Thanks
Chris

I dont think there is much to wear out in the LDA.

You can visually inspect the diaphram or vacuum pump it and see if it holds.

There are replacement accelerator lever shaft bushings available. You could check it by wiggling it to see if its sloppy.

The shaft bore is egg shaped. When I was looking it over, there appeared to be no replaceable bushing. Seems that it needs to be bored and bushed, something I'm not capable of right now.

I would like to find a shop that can do this for me.

Thanks
Chris

Im sure that the shaft bushing is a separate available part

:oops: OK in my defense, I was probably most way through a 12pack when I inspected the pump cover many moons ago. That clarity problem has been corrected long ago and after re-inspecting the pump cover, I do see the bushing. It looks far "rounder" than I remember and the throttle shaft only has some wear, not near what I remember.

Maybe it took beer to convince myself that I needed a new pump at the time...

Is it possible to get just the bushing? I don't really feel like chasing down another pump kit right now just for the one part.

I also see the stop pin in place on the old pump (US vanagon pump body with LDA cover mix-n-match). I guess it probably wasn't performing quite how I remember - oh foggy times of yore.

I have learned much in my short time on these techy boards, more so than the general and not-diesel specific (but still wonderful in its own way) Samba forum.

The moral of my story is that beer is bad, but convenient to blame stuff on. Moral.B is where to find the throttle shaft bushing?

Thanks
Chris

This guy is a member here on this board and sells on ebay as "Prothe".

Might be chinese part but the price is right.

There's a pic 1/2way down or so, but no pic on the page after you click on the pic.

Dang -

I knew someone was gonna suggest him. I've had to check him off my "buy from" list due to a bad Ebay sale. I will say that his IP kit looks to be a dead ringer for the Bosch kit (chinese copy, I assume) and his turbo kit seems nice, though I haven't installed it yet - I'm optimistically cautious on the materials spec'd for his kits.

In a search on the site I came up with a number 068-130-718 that comes back as a "bushing" on worldimpex, no picture to confirm this though. Maybe I'll take a gamble on the $22 price if nothing comes up otherwise.

Tell us about your bad experience. Maybe you can same us some hassle.

huh - I had some pictures to illustrate this but I must have deleted them when payment was refunded.

I guess you can just chalk it up to poor customer service, which I seem to be getting a lot of lately from all over the place and I'm not willing to put up with it any more. Mis-treat your customers and you'll soon have no business.

I bought a used IP sprocket off Ebay from Pete. I didn't expect anything perfect, just useable. The one he sent had been removed using a hammer, causing the sprocket teeth to mushroom on the pump side of the sprocket for at least 1/3 the diameter. Due to the sensitive nature of the timing belt, there's no way I'm going to install a questionable part (this is why I had to buy the sprocket in the first place).

Possibly I came across as rude when I stated that the part was defective and he needed to send a good replacement part in its place. I find it astounding that anyone (especially a business owner) who's familiar with these engines would send something so potentially damaging. Pete expected me to pay to return the sprocket before taking any action. It's insulting that I now have to pay half the original cost to return a part that never should have been sent in the first place.

Lucky for Pete, Paypal issued a "courtesy" credit to cover the shipping charge - their policy is that buyer is responsible for return shipping, effectively protecting shady sellers that ship defective products.

And that's about it - nothing major but annoying enough to have lost any future business from me. I should have known from the start when I couldn't find any contact info on his website other than an email link.
