Re: Repowering old brass - can motors?
Mabuchi and Minneabea four magnet,? six slot motors listed on Ebay in the $3 range are the best.?

Re: Mystery repowered Athearn F-7's
开云体育My recollection is that the HOLLAND motors were offered in the mid 80's as repower options.? They were reputed to have been surplus from computer tape drive.? You know - when computers were buildings, not telephones.? They were mostly suggested as replacements for the comtemorary MODEL POWER FA's and Sharks which had a similar size OEM power.? They were smooth, strong and HEAVY so the longer trains getting popular could be handled.? These converts could pull. I recall reading that they may have fallen out of favor because
they had a somewhat lower RPM and Clubs found them too slow and
not good for mixed consists.? I think that would be an asset
myself.? I try to get them if I see them.? On 7/25/2021 7:57 PM, Jason P wrote:

Re: Mystery repowered Athearn F-7's
I have one powered by an A-line chassis.? It uses an Athearn frame and there is a lead cradle purred in place to hold the motor.? Sounds like what you have.

Re: Broken Bachmann Drivers
Thanks for your help. I followed the link and ordered the wheelset. As soon as I get it I will install it and let you know how it works.?

Broken Bachmann Drivers
? ?I know this is a common problem, and I just wonder if anybody has come up with a solution. I have a vintage Bachmann Plus 2-8-0 with drivers that have cracked nylon axles. I have tried super glue to no avail, and replacement axles are, to the best of my knowledge, unavailable. This is about the third set of axles that have cracked on me. Just what kind of crap is this? The rest of the loco seems OK. Any tips ?? Thanks?

Re: Mantua Power Drive parts
William, list, Option one (direct replacement) follows. One source of the silicone/plastic tubing is model airplane fuel line. ?I was lucky enough to have a general purpose hobby shop near me that had several diameters I could choose from. A sample of the model airplane fuel line is at the web address below; there are several different sizes out there. You may need to copy and paste the web address below to get it to work. Alternatively, using Google to search for model airplane fuel line brings a lot of results. Option two follows. ? Replacing the motor-to-gearbox connection with universal joints is more complicated, but results in less machine friction. ?You also need to know the size of the shaft on the gearbox and the size of the motor shaft (I learned the two are not necessarily the same on at least two projects). ?Two purveyors of universal joints are Hobbytown of Boston and Northwest Short Line (www.nwsl.com). ? I ordered a bunch of universals from Nick of Hobbytown of Boston in 2020.? Doug Kisala
