I have read that the 8 pin board on the older doodle bugs is miss wired
is this true ?

i finally got an answer from
Cynthia about 1 hour ago 
but the sad news is they are still awaiting the part to arrive
from the mfg
terry

I've sent 2 emails and heard nothing
also sent a service request and heard nothing
I can't call because i am mute due to throat cancer

Ideas any one ?
Terry

I found no broken or cracked gears however one wheelset had a short
I'm wondering if the insulator in the center of the wheel fell out and caused the wheel to be out of round   

It Worked
swapping the front truck with the one i bought on ebay stopped the thumping noise

i wrote to the parts dept but have not gotten a reply 

i bought it on ebay and ran it once 2 years ago all i remember was that it had gear noise
i put it on the shelf for two years and just did the install

i just bought a second one on ebay for 35$ and will run it and if it has no thump i plan to swap front trucks

just wish i could buy the replacement truck only
terry

Yes i have but the drive shaft is out of sight andcan only be viewed from the bottom
heres a video and if you listen close you can hear the thumping

Well sounds like you got a real mystery on your hands.

Yes i do
The only other thing i can think of is the drive shaft is causing the
thumping

Ok...go to this link.    http://cs.trains.com/mrr/f/88/t/157193.aspx.       and check posts #6 and 7.....maybe this loose clip thingy is your problem if the gears aren't cracked

Thanks for the link but the clip is not the problem
it actually makes a thumping noise like it has a flat wheel
i'm wondering if the whole housing may be warped since i can find no cracked gears

Quote from: genetk44 on August 24, 2012, 07:02:55 PM
yeah but you can get the gears for $10. or the gears on the axles for $25

Yes but the whole front truck assembly is listed here for

Fr. Power Truck (New-Doodle Bug)(HO Scale) $12.00

and after taking it apart i found no cracked gears so i'm wondering if its
the housing its self causing the thumping noise

I was hoping one of the staff would answer the question of when that part would be available

can't you just change the gear? or axle?

Gears and axels are not sold seperately
Sadly
I didn't find any in the parts list   

Does any one know when the front power truck will be available for purchase ase a replacement part
I have an older doodlebug that thumps when it runs and i suspect a
cracked gear

I think there was at one time. Search the general and HO forums.
