Ahhh, but it does get better! Sitting outside with a light shirt on, under clear blue sky, not quite 60 degrees but close, green mountains, and best of all?..... very few people around. Smiley

Remove the wires at the head as 12 volts could be shorted to the wire somewhere. Other than that you will have to rebuild the Jakes. Kits are available.

Interesting problem.  Here is my conjecture:  Jake brake comes on when two things happen - solenoid that controls oil flow is open, and there is sufficient oil pressure to activate the cylinders that press down on the valve bridge.  If it's happening at start up, oil pressure will be really high until oil starts to heat up, could be forcing the solenoid open, leaking past the solenoid to the cylinders (apologies if that's not the correct term), or something like that.

There are several new "gravity propane heaters" on the market, or so a cursory glance at Mr. Google shows.  I would personally call them convection heaters, gravity has nothing (directly) to do with it.  Simple, use no electricity (except some have a spark igniter), nice idea.  If the heatbox passes a corrosion/crack inspection, there is about nothing else to go wrong.

If there is no electrical power to the Jakes and the are coming on, then one or more of the Jakes is mechanically sticking.  The side that is sticking needs the valve cover removed to see what is going on when starting

This situation is not good if the piston comes up and hits the valves.

My 6v92 has a 2 stage Jake Brake that doesn't work; however. when I start the coach cold, one side of the Jake Brake is on. After it runs 40 seconds to 1 minute (depending on how cold it is), Jake goes off and engine runs fine. The only test I have done is to remove 1 wire from the buffer switch to see if that made any difference. It didn't. I have tried starting with Jake switch off, on LO, and on HI, and that made no difference either. The Allison trans has a retarder and a switch for JAKE, OFF, & RETARD. That makes no difference either.

Any ideas?

@Mike - One of the reasons for getting the bus, pretty low on the list, was as a mobile second domicile, free to move where desired in case of natural disaster or doomsday event. I certainly am not a card carrying prepper or survivalist but conditions and events just make me more uneasy that some big shiiite could go down. It is highly comforting to know that as long as we can escape the bay area and get to the bus, we can survive a whole lot better than most folks.

Clifford and Mike, the effect of the CARB rules on older two strokes has pretty much run its course through the commercial truck industry in CA, at least from what I know. Any that has not had the PM conversion is virtually off the road for any commercial use now as the last of the extensions have run out January 2016. That was allowing some to remain in fleets based on the percentage of the fleet being otherwise compliant and current. There is one other exemption allowing some minimal use, like under 5,000 miles a year. I think that one still is in force.

Agree with you on the coming glut of old buses for sale. The way I read the regulation (3rd link) is just before 2020 there may be a great buy opportunity for mid-late 90's 4 stroke like a MCI 102 Series 60 motor. It seems that by 2020, heavy trucks/buses with 1996-1999 motors will need to have at least a 2010 or newer motor. Operators will surely be dumping them cheap and getting new ones. Time to buy stock in the large truck companies.

As long as the motorhome conversion rules remain intact then we can still use the loophole to buy an old commercial non-compliant bus, convert it, and register it as a motorhome, bypassing the regulation. Much like how we run the old two strokes on the road today.

Until they get rid of diesel vehicles altogether it seems to me that we old busnuts will still be able to run down the road. But as we already experience getting supplies and parts will continue to diminish; take getting low ash straight 40 weight oil for example.

The thing with California, specifically the SF Bay Area, is people put up with all the BS, extreme costs and regulations, due to one thing. It is in the top ten most beautiful and enriched, culturally, socially, and geographically, weather, economically, etc locations in the world. Dec 9, sitting outside with a light shirt on, under clear blue skies, 60 degrees, overlooking the green rolling hills. Does not get any better. Now, don't ask once I have to leave to house and go anywhere. LOL

@Neodaddy - LetGo - the problem isn't finding ways to get rid of stuff. The problem is my wife accuses me of being a hoarder. I seen them shows and I am no hoarder but I'll admit it is hard to let go of anything that seems like it can be repurposed or reused down the road. Hey, my insurance covers seeing a shrink; maybe, I can get hypnotized to get rid of all the stuff. LOL

How many Crowns sold in total as schoolies?  Dunno.  Crown also made special weird stuff including weirds, fire apparatus, mobile libraries, medical vans, military, etc..  Each practically hand built.

In total?  You will get different numbers.  I was told around 5500 but that might be wrong.  Started around 1949?  Ended 1991.  There are many websites discussing Crown Supercoaches. ... 



Try a Google search?
