Hi Day,

Nice truck - B-model wreckers are always good looking rigs.

Would you like to have your truck listed on the B-Model Registry - a place to try to document all the B-models still showing signs of life?

If so, you can send me your VIN via PM, or you can go to the registry website and fill in the data form, and I'll get you listed.  If you're not comfortable listing your personal info, that's fine, but it would at least allow us to know that your truck is still out there....

Here's a link to the site if you'd like to check it out:  http://www.mackb-modelregistry.com

 

Thanks!

Mike

If the back box shifts stiff look at the linage on top of the trans for the rear box.There is some grease zerts that the two rails go thru and they may need clean and regreased.

Guys:

Terry, your procedure had occurred to me, and I'll give it a try right off.  Thanks for the advice.

Mike, I'm anxious to get on the registry, and will complete that procedures.

Appreciate the help.

Hadn't thought of those zerks on top of the tranny.  I'll give them some grease.  They probably haven't seen grease in years.

my triplex back box shifts hard til its warm to. usually takes 15-30 minutes to get some smooth shifting out of it. greasing the fittings and rods wont hurt either

I'll certainly post some pix when I get her painted this spring.  Roughly what's left is:

--install some of those rubber fender flares on the fender cutouts we did

--paint it

--hook up another air tank

--hook up pto

--for you wrecker dudes, I have to move the control handles which were originally on the side of the truck.  I ran out of fender space, and will install the control handles on the surface of the wrecker bed.  The geometry of these control handles should work the same, just shifted in position 90 deg.  This control rod mechanism is a nightmare anyway, and explains why hydraulics caught on so fast.

Should have it on the road by the beginning of the spring season.  By the way, this B81 is running a 237.

Just test drove Terry's suggestions above and it worked fine, good enough to get me out on the road where I could really warm it up.  Appreciate the suggestion.

I always start mine and let the boxes run while building air.  With my added aux, I run it in neutral and let the the front boxes run to loosen up.

Neat project.
