bogie wheel locking the brakes

Did you go and weigh that bogie on a scale?

All this angst and no confirmed reality?

Flat spotting tires that cost how many hundreds, vs a multi-axle scale ticket at the Cat scale?

Give in to the Dark Side..?

Happy coaching!

Humm.. I did have my bus weighed at a CAT weigh station at a truck stop. I was able to get a front and rear weighing. Honestly, I can't remember the arrangement of the scales and if I got both front and back weighed at the same time or had to move and get second weigh.

again, get it weighed instead of all the fretin. Also if bogie received more agressive brake lining or less agressive on drive axle can add to the mix.

Some DOT inspectors carry portable scales in their car. They can weigh one wheel at a time. Don't ask how I know, lol.

Not a easy job David some people just drop the rears a 1/4 or a 1/2 inch to add weight to the bogies ,it's still a job and the jacks are accurate most of the time they are with in a few pound of the scales used for Eagles,there is no way to read the bogie weight on Cat scales,Wayne has a set of Eagle scales call him and go for a visit some week end

Some FBO'S at your locsl airports will have portable scales, might want to check there.

I put a gauge on each R8 relay on the service output fittings for the drive brake and bogie brake and both read 60psi with a treadle brake application. That eliminates an air relay issue.

It sure appears I need to adjust the torsion spring 1 spline each and add 500 lbs of force. Ugh. That will put it just above 4000 lbs each. Dan Lentz doesn't recommend that weight.

Not sure what to do.

Just above 4000 is the maximum that he recommends, 5000 lbs is the rating for the bogie torsion. This is assuming that the ride height is correct on the front and rears, otherwise the bogie will be off. It's a lot of work, but the bogie tires will appreciate it.

Careful with the bogies David last thing you want is to screw one up those haven't been available for years

Yea, I've read that. I guess I could drop the ride height a bit since I'm and 13.75 now. That will add weight to them for sure.
I have a trip to Oklahoma. I will fool with it when I get back. How about a supplemental air bag. Any place to mount it on the axle arm? Bracketing looks like a real challenge.
