A few years ago I had a C30 with a 454 and 4 speed always had a lean issue it had a holly electronic adjustable throttle body the control was mounted under the dash like a CB you could adjust it while driving but even on max fuel setting it still had the problem take the air cleaner off I could actually see large amounts of fuel being sprayed down the throttle I switched to high quality non ethanol fuel and that helped a lot never did find any other problems and ran pretty good that way

1960 B-73 radiator shutters
D-Day replied to chillywilly's topic in Exterior, Cab, Accessories and Detailing
I have both types of shutters and they were attached the same way three fasteners across the top and three across the bottom the small brackets are bolted to each radiator tank and have U clip spring nuts they are an odd shape maybe just caught under the center bottom bracket

We have a 450 G that was a great little machine until one of our crew decided to use it to push a road through rock and broke a final drive and I need to look for parts again they are hard to find, if it hadn’t been abused we would still have it to use
-
I have the same problem

I need a 12 volt starter for my '48 KB-7
D-Day replied to Joey Mack's topic in Electrical, Electronics and Lighting
Best to keep your thumb on the same side of the crank handle with your hand if you grasp it like a beer you will appreciate the timing advance difference and a little backfire when things are not perfect -
Looks like 6Qj417A maybe hard to find possibly used on early R or F models as well
-
That truck was west coast had budd hubs all around 1965 yes no brakes up front I found studs for the aluminum wheels still available I will try to get a casting number or something for you axle is a FA 5071 should be the same spindle and bearings for 507 west coast is where to look that is the only one I have
-
Very nice B 61 I have a friend with a B 61 and I think he still has an extra air cleaner I will check with him tomorrow if time permits
-
No easy answer in the past I have redrilled the frame to relocate the rear mounts but sometimes that is not possible if there are other holes to close I have also fabricated mounts for the bell housing making an offset to move a small distance and then shorten the driveline its getting difficult to find the right combination of parts that you need for engine swaps
-
A lot of the early B models had a single plate push type clutch later the twin disc push type clutch came out then the twin disc pull type clutch took over different bell housings flywheels and input shaft for the transmission were used as well as all of the clutch linkage and other related parts
-
This is where the magic happens the rocker arm adjusters have 2 oil reservoirs and pistons that apply the retarding action by opening the valve on the longer profile at the rocker arm not the cam lobe when the small parts inside the rocker arm adjuster get worn that is where the problem starts with dynatard
-
I was able to get a measurement from the B73 mounts the green one on the transmission side from the bottom they are actually offset about 3/4 of an inch so you could gain that way possibly could not find part number yet
-
Same thing with the front mount not only in a different location but different bolt pattern maybe a B61 mounts would move it back but you have to measure everything carefully
-
The transmission mounts look similar but are not the same from a B755 and a B73 also the frame side has a different bolt pattern but not the transmission side also you can see the location as compared to the cab mount on the other side of the frame 11 inches in difference probably similar difference in the B62-B61
-
I have some out that I can look at maybe tomorrow I did notice the B755 I am working on the location of the frame side of the mount in relationship to the cab mount is a lot different than the B 73 I am removing the transmission from that is in the shop now they are relatively the same they both appear to come off the transmission at a 90 degree angle as opposed to being angled forward or aft I will get some pictures as soon as possible

Mt st Helen’s eruption was may 1980 it was a huge event in Washington state the ash was everywhere before you cut a tree you had to ax cut the bark off first or you’re saw chain was instantly dulled also everyone put pantyhose over the intake on the air cleaner to clean as much of it as possible or it would clog the air filter
-
Another picture from camp baker at mt st helens one of the few that were found maybe a off road kenworth hard to tell
-
Finally got the 865 to the shop for the B755 project got a lot of work to do before I start a thread on this but I’m working on it
