Hi
I'm looking at a G-800 which has some very unusual corrosion inside the body. It is a 10mm thick and had bent the bodt casting and pushed the wheels over. Anyone seen this before and any suggestions as the repair.

That looks liek it could well be the good old zinkpest that hasn't been stopped, but allowed to go for a couple of decades.

Personally unless you have another chassis for which you need a body i wouldn't touch it. Once you get the body off that the chassis will disintegrate into a heap of powder.

This looks like only the separate ballast piece is damaged.
You should try to remove it, and check that the rest is OK.
I may have a spare somewhere if you can establish that it is indeed the problem.
Keep us posted.

I just took my G800 boiler off and I think you are correct that it is the lead weight that has corroded. This is not zink pest I believe unless they added zinc into the lead. Thanks for the offer of a replacement part. I will keep you in touch if I decide to buy the engine.

Ok, no sweat.
When I come across that part, I'll let you know (yes, you guessed right, my place is a convoluted mess BigGrin BigGrin )

Hi
I did eventually buy the engine as I thought it was worth the risk. In the case of me unable to get the engine working it had the original box and instructions. I bought it from the US and it arrived last week. The owner was right about the white corrosion just falling off in powder and lumps. I managed to get the boiler off and the rest of the loco was intact apart from one side of the boiler bowed. The lead counterweight was heavily corroded but with the assistance of a hammer and chisel I got it out. I was pretty sure the part was unsalvageable but once again with a wire brush and file the weight cleaned up. Then a quick coat of black paint. Not quite like new but good enough. I then gave it a good clean and oiling. I set up a small 1950's circuit and powered it up. No movement what so ever. I then got 2 separate wires from the transformer and gave it some direct power and off it went. So back on the track still no good. Cleaned up the 2 pick up shoes and off it slowly went. I let it build up speed and completed 20 circuits. Then the nervous bit trying the reverser which can be very problematic. Once again one push down of the control knob and it went in neutral and one more into reverse. It's a fantastic model and I think one of the best from that era. 65 years old and did not miss a beat. I bet Marklin are kicking themselves for building them so well. I've got a video if there is any interest.

Great piece of work! It's nice when an old lady like this can be brought back to life. I hope she gives you many hours of joy.

That's a good solution with the lead weight. What did you prime the surface with before you painted the top coat?

Excellent job.
this is a good find with original box , wooden insert, original store label from Wiesbaden. etc.
Probably made the trip to the US in the bowels of a C-54 or C-124 MATS aircraft!
Very nice and laced with a little history.

Agreed - and it has the original solid centre rail pickup shoes as well, which are in reasonable condition ... ThumpUp ThumpUp ThumpUp

Nice save Roger. ThumpUp

If I would have saw that mess I would have most likely passed it up. Glad you had the guts to go for it.

Congrats!

It's good you've managed to salvaged it, I thought it had deformed the loco body, your first photo must have some lens distorsion.
I bought the same loco a long time ago, I disassembled it to see the internal construction but the lead weight was so tight I thought this couldn't be normal and figure out that it might be swelling and could damage the body. I did take some slices of the lead -might have used a very sharp retracting knife but I don't remember for certain- then I put it back -that was may be 10 years ago- a few months ago still seemed to be ok. No dust on mine except a tiny bit where the coal goes in the tender which is the most common problem I've seen with this model.

This is only the mold; You can remove it with lemon juice.

Good luck.
