Ferret Fluid Flywheel rebuild

The news will delayed by a bit more than a week, maybe even a month, no I am not pregnant, despite rumours. I'm just fat.

You will just have to wait Sam.

Thanks greatly for the wealth of info you shared on the flywheel!! I need your help though. I purchased two new drain plugs and washers. In replacing one, I failed to notice that the initial threads were molded improperly and I stripped 1/4" of the threads on the flywheel. I retapped the remaining threads and recut the plug so both are good now... except that I am missing first 1/4" of threads on the female side. Question, can I use a slightly longer drain plug (will replace both for balance) so that I can get a full grab of good threads? Is there enough open space in the flywheel to allow for such an idea or do I need to consider drilling out the remaining threads and using a helicoil to give me new ones? THANKS!!

By the way, for info sharing... the threads on the drain plugs are 1/2" x 14 British Parallel Pipe threads (commonly referenced as BSP and/or BPP). Just thought I would share if anyone is ever in my predicament!

Tim,

I am unable to answer your question as I do not have enough technical knowledge on the subject. I don't have one handy to reference. It will be a while until I do as things are packed away somewhat at the moment.

I would heartily suggest posting this same question on the HMVF that has many technical folks and also speak or email with James Hill at the REME Depot in Texas, he is a good egg and very very technical. He has a day job. If you would like his email then ping my email and I will give it by return.

I look forward to hearing the results.

I would say that like algebra the fluid flywheel should have done to one side what you do to the other for the sake of balance, as upon close inspection these things are very finely balanced.

Back to the caged nut. Isn't that lip supposed to go into the hole, to center it for welding?
