Re: Mark VII Idler Shaft Damage

Wow! Can’t wait to get my parts out to you Mike!

JPG, what were the eclips you sent him? I have two different sizes which doesn’t exactly make sense and one is beat up.

Re: Mark VII Idler Shaft Damage

The control sheave bearing seems to have some wobble in it with the part that comes out the end. Is it normal? Bearing seems to spin fine besides that. Probably a non-issue since it’s held in place by the nylon speed controller part. I’ll check with Motion with the info provided to see what they can...

Re: Mark VII Idler Shaft Damage

I need to order new bearings to go into the eccentric so I can send Mike the parts he needs and the ones in there now are KOYO S375Z bearings. These appear to be no longer made. Does anyone know a suitable substitution? While I'm at it, I'm going to try and replace all my bearings because... why not...

Re: Mark VII Idler Shaft Damage

The threads seem skippable if you can retain everything like the Mark V does. Not sure what the secret is (if there is any). I'm in talks now with Mike to give this a go.

Re: Mark VII Idler Shaft Damage

Miken, if you think it'd be easier to simply remake this shaft, I do think it's the better option. Sounds like you have the tools necessary to make this happen. I'll send you a PM.

Re: Mark VII Idler Shaft Damage

Yeah, adapting it to a Mark V speed controller setup crossed my mind when I found that post. I'll have to pull the idler shaft out of my Mark V and see just how different they are. It seems like a new (used) Mark VII idler shaft would be ideal but I've not found a source for one yet. If I had a meta...

Mark VII Idler Shaft Damage

I'm rehabbing a Mark VII unit I purchased recently and one of the issues I found was that the idler shaft that holds the eccentric bearing had a lot of play in it. Disassembling it I found the shaft has worn away from where the bearing is supposed to ride. Idler Shaft Bearing Surface.jpg Does anyone...

Re: Mark VII Motor Hums in Reverse

Oh, I’m working on the Forward/Stop/Reverse switch at the moment. Though I think the bearings in the motor could use a replacement. I’ll post a video here when I have a chance to get y’all’s opinion on that. I could be overthinking that one. I carefully pulled the cover off the switch and was able t...

Re: Mark VII Motor Hums in Reverse

Okay, so the case and the male connectors aren’t attached to each other directly? It looked like the connectors were sort of pressed into the case. I have not noticed any screws that can be removed besides the one that holds the lightbulb post. I was thinking about graphite or something similar too ...

Re: Mark VII Motor Hums in Reverse

Alright, so I got a chance to continue troubleshooting and noted how tough it was to press the reverse button. I tested the connections and everything passed. I decided to try cleaning it up a little anyways and then the buttons got harder to press. I decided to do the drill and spray procedure and ...
