F'Train, I will try to post a picture if I can. Looks like it will not be the easiest thing given diameter of spring packs vs what is on there now. Bob

Any ideas out there? My 61 B has an RAD 111 35,000 lb rear axle. The brake chambers are those big cans that are about 5" in dia. and about 6" long and they are on the front side of the axle. On the back side, there is a bar that connects the right and left slack adjuster. Existing parkig brake is the manual Orschlen lever connected to the drive shaft- not much for a single axle with a 46,000 lb gvw! My question is, what would the best way be to convert this to maxi chambers? Bob

Model B Radiator Fins
Red Horse replied to BigRedMack's topic in Electrical, Electronics and Lighting
Duh! why did'nt I think of that. I have what was a B-68X that someone converted to a 673- left what I assume is original radiator in that did not have shutters. I just bought a 61 (for the cab and the 673 quad box) and the shutters and the shutterstat assembly looks good. Common sense would have told me that if I looked at it long enough. I also salvaged the radiator shutters and shell off of a junkyard B-42 -just before the shears got to it. and I have that complete assembly. Is the shutterstat rebuildable to any degree? Any info would be appreciated. Bob -

Guys, How does the shutterstat get its temp info telling the shutterstat to open or close? -
B-61 Door Alignment

Guys, speaking of door seals, what is a good replacement product for the seals? -
10-4 Freightrain- My problem then will be the guy wont sell the carrier plus the axles blah-blah. I'm afraid I' going to be going down the road at 45 MPH with my 9.05 CRD 62!
-
Freighttrain, Thx for the response. Looks like I'm gonna have to study this!
-
I have a CRD 62 carrier and I am told that a CRD 118 is a replacement. The only issue is the CRD 118 spec sheet says the axles have "involute" splines. What are involute splines. the CRD 62 I have has straight splines on both ends. Can anyone help me out.?
-
So Fred, would you have a CRD 118 in say a 5.52?

24" rubber with 8.24 rears and an OD quad box (.74 ) wiill give you (2100 X 60)/442X.74 X 8.24= 46.75mph This makes the assumption that 5th hi is .74 If it wasn't an OD and was direct, same combination would give 34.59 mph I am going through same exercise.. I have what was a B-68X. It has a 9.05 rear and when built was a gas job with a quad box. somewhere in its 47 years, someone dropped a 673 with a duplex in it. I have not had it on the road but was told by the last guy who drove it on the road (he plowed with it) he said it would do 35! bottom line when yu give away 400 RPM's going from gas to diesel you pay the price.

I have an RAD 111 rear axle which has a 35,000 lb. rating and a CRD 62 carrier with a 9.05 ratio. The truck was originally a 540 gas/TR720 (B-68X) and at some point, someone put a 673 and Duplex in it. That gave away 300 RPMS gas to diesel and I believe the crrent Duplex is direct. Anyone have an idea where I might find a CRD 62 with a higher gear? Mack Museum (Don Schumaker) advises that a CRD 118 was a running change for the 62 so that is another option if I can find one with a higher gear. Appreciate any thoughts anyone might have on a potential source.

How about it. Anyone have an experiencing with having a rad shell chromed?
-
RC-51, Where in Mass? I just registered as well- Bolton B-68X Some helpful guys here!
-
Guys, thank you all for the feedback- No doubt the gas engine (3000 RPM) made a big difference vs a 2100 rpm diesel. It does have big rubber (11:00-24) but 9.05 is a killer. B61Fred, emailme at fd68brnco@aol.com with what yo have for gears. Rear is an RAD 111. Bob

My B-68X was built with TRQ 720 quadbox and 9.05 rears. At some point, someone put a 673 and a duplex in it. I have not driven it on the road but I tracked it down to the last guy who had it registered and he said it did about 35! I have the opportunity to get a quad box out of a B-42X but I'm assuming the quadbox in a gas job had a much lower torque rating and is a different animal. I will get the vin out of the B-42 but just curious if anyone had any ideas?? I have to believe that getting a quad will be a lot easier then finding a gear set for a RAD 111 rear. Bob

F-Mack, Thanks for the quick response.Bob

I was in a yard yesterday getting some items off a B-42. One thing I needed was the glove box door. I was running out of time and couldn't get the hinges loose, so I took the easy route and grabbed the door. In looking at my truck, the lip of the box opening has been bent- so whoever robbed my original door looks like they ripped it out. Were those hinges spot welded to the dash assembly? Bob
-
Rob, Actually I meant the frame from the door and I really hadn't looked at it before I posted the question. Someone gave me a better set off of a vehicle that has about 100 hornets living in it! The glass is good - a little "smoked" in a few spots-(both of mine are cracked) and the frames appear serviceable and even have the locks on them. Mine don't have locks and much of the channel is just about rusted out. Bob

Well nothing "smart ass" about your answer, Thx for the info.

Guys, Any particular trick to quick removal and reinstallation of the vent window assemblies? Bob

New Harness Or Rebuild
Red Horse replied to Red Horse's topic in Electrical, Electronics and Lighting
Guys, thanks for your replies. I'm just getting into this and am trying to come up with a game plan- and a budget. Idid have 1300 bucks in mind as harness number but Paul I note you comment on Top o"the Hill. I will check them out. I have buddies who say- "no big deal". It won't be if I can get them to do it! -
Guys, I have a 1960 B-68X (converted to 673 with 12 volt) that has been off the road for probably 10 years. the wiring is virtually non existant. It appears that there are various places to order complete harnesses but a buddy of mine says.."why bother- its simple" . this thing was built as a dump and that is what it will be. Is the time savings offered by going the harness route worth the $$$?? Any thoughts?
-
Joe and Paul, thx for your responses. Trust me I won't be bashfull! I've actually only seen the truck once about a month ago and hope to get it hauled in during the week. Then I'll be getting into it - with the help of some knowledgeable buddies- and we will see what we have to work with. Bob

Hi everyone from Bolton MA. After a lot of hand wringing I wrote the check last week for a 1960 B-68X. The 46,000 lb GVW and the 11:00- 24's made me do it! "68" is a misnomer as somewhere in its life, someone took out the gas motor and the quad box and stuck a 673 and a Duplex in it. Be looking for a lot of dumb questions and thanks in advance for your help.
