Mc; you will need to run your rack and adjust your governor setting for the switch you need the Jake gauge it works better than a regular feeler gauge.You guys are wrong about the old guys being the only one to work on 2 stroke the military has hundreds of these young men and women working on the engine and fwiw they are taught run the rack in the night time and with a dial indicator when a gauge is not available try that guys

Go to the Jacobs engine brakes web site. They have an instalation manual in pdf. You just install them, then adjust them so they open the valves the right amount for your engine.

Mc; go by the manual for sure there is more to it than just installing the brakes you have the buffer switch to deal with , the fuel lines and the oil tubes   have a great  day

We should get some of these old mechanics to give us a seminar on how to tune up a 2 stoke. Now there is an idea for a bus rally...

I would be tickled to just see it done on Youtube. Anyone up for it the next time you have your rack run?

How much time is normally used to run a rack on an 8v71?

Having a seminar at a rally sounds like a super duper idea. Cool

I'm thinking about that for TBR next year...I know scary thought huh? Wink

I'm sure we could find a experienced mechanic that would like to share his knowledge.

A talk and demo on the complete tune up would be best, starting with setting the governor, to running the rack, to adjusting the valves, timing the injectors, setting the gap on the Jakes and setting the iddle and max no load speeds. A good presenter could do it in a couple of hours. Or 2 hrs in the morning and 2 hrs in the afternoon. These are just preliminary ideas. Of course finding the mechanic/lecturer would be the start. I'm hosting the spring BC Bus Nuts rally in the spring, so I'll ask if there would be any interest, and look for someone to do it. I know some mechanics I could ask, who know others maybe...

It will be in Invermere, BC on the May long week-end. I am currently working on confirming the location and time and details. Invermere is in South Eastern BC, half way between Cranbrook and Golden, directly North of the Idaho Panhandle. We just had our fall rally in Spokane, Wa. a couple weeks ago. There were 23 coaches and a great time was had by all.

JC keep me in mind, I have done it all except for the jakes, thats what I did for most of my 33 years on the buses. Most were 6V71's. some 8's.

Sure wish I would have know about the rally, it was about 10 miles from me.  Saw a bit in the newspaper about it.

Maybe next time.  Be sure to  let us know about the spring rally.

Thanks

This is also a good idea for a series in the magazine, hint, hint, then all can see if we can't be at the rally.

Dreamscape S&S is not just in Texas the CO is in 6 countries and 11 states not all have engine shops but Houston or Dallas would work best for me and believe me some of the young guns from the military are a whiz on these engines  have a good evening
