The rear pilot of the recent production GP-30 was not flush with the chassis. Here is a picture:



GP30 Rear



For this vantage point it can be seen how the rear pilot extends out from the back and the steps of the pilot are not in line with the chassis.



Now that my unit is about one year old and the warranty is kaput, I feel comfortable with a simple modification. This is really simple modification to make the rear pilot line up with the chassis.



First, the pilot was removed and the posts were drilled away and the surface filed down until smooth and shiny. This was done on both sides of the pilot where the screw holes were.

Next, bisphenol-A epoxy resin was was added to the truck posts and the pilot. Here is a picture of the truck and pilot where the pilot is fixed into place with bisphenol-A epoxy resin.

The locomotive is then assembled back. The liontruck design makes all this very easy. Here is the bottom view of the truck where the truck brake shoes extend behind the pilot steps:

Here is the side view now where the pilot and pilot steps now line up with the chassis:

Here is a full side view of the GP-30 with the "corrected" pilot

Lastly, here is a prototype view of the locomotive



Where it can be seen how the brake shoes of the rear truck extend behind the rear pilot.



A simple fix to the cosmetic problem that is inherent to the legacy GP-30's made over the past year. Hope this helps.

Very nice job. There was an article a year or so ago about doing this modification, but it was quite extensive. I've had my eye on a Lionel Illinois Central GP-30 for sometime, but thought the corrective process was too involved. Your process has me rethinking my decision.

Is the epoxy the only thing securing the steps or did you drill new screw holes also?

I did the thread a year ago but mine was a 3RS conversion with a fixed pilot and Kadee couplers, that's why it was so extensive. When mounting the pilots to a fixed position, the rear trucks will not rotate because the rear brakeshoes hit the steps.

 

If you're keeping the truck mounted pilot and claw coupler, WBC's way is a very quick and simple solution to the offset pilot.

Here is the fixed pilot conversion topic link:

I did not have time for such an extensive fix to the pilot, though the conversion from the swinging pilot to a fixed pilot turned out great.

 

I did not use screws to fix the pilot in place. I did tap the surface of the pilot from the top where a recessed screw could work. I filled the tap with epoxy to make the bond stronger; there is continuous cured epoxy from the top to the bottom of the pilot through the small screw hole. The pilot would most likely need to be screwed in from the top as the posts have to be removed to move the pilot forward.
