Just keep experimenting.  Unless you really like shifting?  LOL!  I used to play a lot with mine for no reason...then after 10-15 yrs I only use enough gears to get the job done.

That's good advice, thanks.  It's time to get in the saddle and try out some of these options.  This discussion has been very valuable in one particular way: I've realized that  I've been spending too much time in the lower gears getting going, and maybe even splitting in the higher gears as well.  Going to forget about LO-LO, and get into the higher gear shifting sequence at about 2nd HI or 3 LO, and take it from there.  

The nice thing about this particular quad is that it's so easy to shift the compound, at least after it's warmed up.  

Appreciate the advice.

Drove it around on the weekend.  I was pretty happy with 2nd Direct, 2nd HI, 3 HI, 4HI, 5 HI.  However, did notice a) had to use clutch on shifts; b) it was a significant jump in these 3-4-5 HI range shifts.  I googled the effective range of the 237 that I have in this truck, and learned you can safely wind it up to 2100, so I believe I'll wind it up a bit more when I try this again.

Also noticed that, when I put brakes on (such as at a stoplight) air pressure leaked out and tank pressure dropped from about 118 max to below 60.  Truck then started sliding backwards, which was heart-stopping, until I kicked in the spring brake and sat and let pressure build again.

Something to fix underneath, I believe.

chock the wheels and slide under while somebody touches brakes, could be a multitude of things, from front to rear!!    terry:MackLogo:

Best thing I liked driving a B was the look people give you when you run through a few gears backing up.  :)

Yes, you can run that 237 up to 2100.   Though some I've heard don't seem to pull strong up there.  Mine seems to do fine?

If you want to not use the clutch, remember to ease off the throttle just before you want to shift.  That eases the torque off the gears and will allow you to pull it out of gear.  If you have it pulled tight, you won't be able to shift without the clutch.  You'll feel it want to slide out of gear when you find that sweet spot. Steep hills, likely  not, as you might loose too much speed to catch the next gear.  It's a learning curve.  It took me all summer to get used to shifting my 237 compared to the old 673.  The shifts were much slower, as the motor doesn't drop in rpm as fast.


Shifting in Reverse?  Simple.  Start in LO, get it moving, ease off throttle, slip into Direct.  Run up RPM, ease off and slip into OD.  Works really slick actually.  I do it every time I put mine away as I back up my driveway into the garage.

 

Air leak?  Check air chambers(broken diaphram) or even a line/fitting.

If it’s leaking that fast you should be able to easily hear it and locate it with someone else applying the brakes while it’s chocked.

Problem with brakes was easy to find.  Apparently aliens came out and removed the line from the quick release valve to the right front brake.  Reinstalled it, everything okey-dokey.

Tried winding up the 237 to close to 2100 to facilitate shifts from 2 HI-3 HI-4 HI-5 HI but I didn't think the engine liked it much.  Sounded like the valves were floating, or what I imagined to be floating valves.  Perhaps more accurate to say that the power in the engine dropped dramatically at about 2000.  In any case, I think the whole sequence worked well from 2 LO-2 DIRECT-2 HI-3 DIRECT-3 HI-4 DIRECT-4 HI-5 HI.  In other words, splitting in 2, 3, & 4 across DIRECT & HI.  

I must say that the truck runs like a champ, although I don't know that I'd care to make my living in it, or drive cross country, but plenty of guys did quite nicely.

The shifts in the compound of course are dead easy without clutch.  To shift both boxes, have to use clutch, as follows.  Upshift is Main box first, compound 2nd.  Downshift is the reverse.

Does this sound reasonable?

Thanks
