Hey ya'll, Hope you can help me with a speedo Gear and Governor question.

New owner here, I can't tell you how useful this information is on this
list and facebook. I'll be driving home a 26 foot 77 for about 800 miles
next weekend. I've watched the video, read the new owner checklists,
blacklist, and I am about as prepared as I can afford to be right now, but
this one seems easily avoided so I wanted to sound it out with the crew
here.

As i understand it, the plastic governor gear can strip when speedo or
speedo cable friction becomes too great and jams or otherwise breaks
causing an inability to shift gears up from 1st.

Is there any harm in running without a cable connected to the transmission
and simply putting a dust cap on the cable port (transmission side) and
giving up using the mechanical speedo and cruise if installed?
I have on order a GPS speedometer with odometer that requires no connection
mechanically. I just want to rationalize that it's mechanically safe to run
with that transmission side port capped.

If the speedometer cable is such a disabling problem, I want to remove the
possibility of this failure on my first journey and potentially long term.

Thanks for your advice.

Jeff,

Your "no speedo" plan is sound -- 'though probably unnecessary if the
speedometer isn't jumping or otherwise sluggish. Stripping the gear isn't
as common a problem as you've apparently been lead to believe.

Welcome aboard, and good luck on your maiden "voyage".

As long as you don't have an original cruise control, capping the cable won't hurt a thing except the speedo, which simply won't read. If you have the OEM cruise, or an aftermarket with a speed sensor in the cable, the cruise won't work with the cable removed. For 800 miles, if I got a cruise control I'll use it.

Jeff,

Welcome to the group, family, cult, asylum......

Nothing personal, but be cautious of advice on FB, I have seen at least two good coaches end up going to scrap because the new owners got and took wrong advice there. There are a few of us that do write there, but I no longer try to redirect bad advice. I got worn out. We have several here with extreme mileage and decade level experience to draw on. You can take what they write to the bank.

Your worry about the governor gear is well founded. The failure is very frequently the cruise control. The easy check is to disconnect the cable first at the cruise control box right where you are kneeing when the engine hatch is up. Then note the length of the cable core that is extended. Pull it out another inch and spin it. If it binds at all, leave it pulled. This cable runs very close to the exhaust and it is easily damaged by the heat. If you push it back, be sure it goes all the way back as the square on the other end has to mate.

You can run like that, just be sure to tie the cable up securely.

With the cruise transducer disconnected from both the speedometer and the governor, now you can put a small screwdriver in either cable port and make sure the transducer is free. I have seen these lock up. You can also try to spin the core of the cable to the speedometer and see if it is free.

Can you tell that some of us have had too much experience with this?? (Not just with coaches.)

Now, you found your way here and that is a really good thing. You will soon discover that the coach is more then just a big new toy and that its real value is the community that it can connect you to. This is a very supporting community. We are all eager to see that see that you get to enjoy both the coach herself and what it can do for you. Motorhome travel is like nothing else. But the community is truly the special thing. We all have Black's list stories both ways. To this end, please build a sigfile to use here. It should have your real name (yes, you are using that already - great) a short about your coach (year, model and any major mods - it can all matter) and finally a better geographic reference than MA (Williamstown to Chatham is about 200 miles) and you best chance maybe someone in another state.

As a final thought, this amazing community is a very rare bird. The only other that I know of like it is that of the watermen that are my world. For that reason, I like to welcome new owners much as any new owner or vessel is welcomed there. So,

May the Good Lord bless this coach and all those that set forth within her.

The gear on the Governor is a type of compound that the heat deteriorates
and not a bad Idea to replace.
Better to replace now than on the side of the road.

I capped the cable port, discarded all the excess hardware and recently bought a low cost GPS based digital speedo/odometer/altimeter/clock etc etc.

https://tinyurl.com/y26shcf9

It works just fine but the one button/dial control is a PITA. Using it as a HUD requires physically attaching it to the windshield like a rear view mirror.

Eventually I'll add an electronically driven cruise control.

Thanks all for the welcome and technical responses. I know what and how to
check to mitigate this problem now. :-)

Coach arriving soon ;-)
