All was going well. I removed the dump body (it was in poor shape) and then I was going to install the fifth wheel. Well then I decided that I should address that frame crack and as long I was there I should...... I think I blacked out then, when I came to this is where I was. I think the cat had somethig to do with it. Hopefully picture will attach. I will try to add others to my gallery. Chuck

When I find evidence of them visiting a area. I ussually leave them a little antifreeze in a old jar lid in case they get thirsty after chewing my stuff. Seems to do the trick for me. Chuck

Rod, I think I have found enough for my needs. Thanks for the reply though. Chuck

The 4.00 ratio was very popular in the single axle R and U models from 1965 production on. I'm not sure on gear set interchange with a older carrier. But a newer carrier should go into the older axle housing OK. Chuck

Hi folks, I thought I would tell you a brief story about my adventure with CT DMV the other day. I needed to register a dump trailer that I had purchased. This trailer is a 1979. I had been looking for something old enough to qualify for antique registration that was in decent condition. So off to DMV I went. After explaining my intent to a few people there they gave me the forms to fill out. Then came my turn at the counter. There seemed to be a little confusion about what I wanted to do. Then there were several trips the clerk had to make to ask the supervisor questions. Then the answer came back "we don't make antique plates for trailers". But hey said if it was not commercial and for my own use I could register it as a "Camp Trailer". So I walked out of DMV with a strange smile and registration for a 80,000lb camp trailer. I wonder what the police will think? Chuck

10.00 x 20 are 500 rev mile tires , your trans is direct in high. Divide 500 into 2100 and you will get ratio needed for 60 MPH. 4.00 ratio is very availible but low HP on a 673 may not pull a full load at speed. Chuck

David, I was thinking it might be a 510 but I can't find the stamped numbers. The only info I have found for B60 says it should have a 465. Also I''m in CT, that may be too far for you but I'll give it a good check over as far a compression and oil press anyway. Chuck

JJ yes that is a duplex. Do you know which one you need? I have several of them around here. Chuck

Luckily it followed me home. Hyd fifth wheel sure will be handy. Chuck

Can anyone help me identify this engine? The only info I have says ID# should be on rt frt eng leg? I do know it has 12 headbolts per head and it uses D-14 plugs. It is currently on a B-60 chassis. It does run if anyone needs it. Thanks Chuck

Axles have had several changes. Sometime mid to late 80's full floating axles went away on 44's in favor of flat flange type. Shortly after that iron housings dissappeared in favor of welded steel. Chuck

I could be wrong but I seem to remember the new style seals also need new style springs. It gets to be an expensive update. You might want to check with a machine shop and see what is availible aftermarket. Let us know how you make out. Chuck

Hi folks, I'm looking for some ideas on what to do with a set of single axle springs for one of my B models. I've got a nice matched set of springs but they are kind of rusty. I plan to take them apart but how should I clean them. I thought of sand blast but will the surface be left too rough? I'm thinking of my needle scaler it leaves a better surface and seals the pores in the metal. Then the paint. Paint the entire leaf, mask off the center 6" or so for good U-bolt torque, only paint after assy. And then what about powder coat? So many decisions, help. What have you folks had success with? Thanks Chuck

j.j. The B60 doesn't have the 707 eng it's the smaller one. I pulled the plug out yesterday and a few were very ugly. They had lots of rust on them. Engine is complete though if anyone needs parts. Chuck

Rob Most light to med duty dump bodies have 1/8 - 3/16 mild steel floors. 5/16 shouldn't be nesessary unless you haul shot rock or concrete rubble on a regular basis. Chuck

Well folks a quick update on this pair. The B60 looks the best but isn't. The cab and sheetmetal is poor ( I think they put the bondo on with a snow shovel) The engine is also very tight. Lots of good hard parts and small misc. The B422 has been worked very hard and then raped. Front end very worn out, broken rear springs ugly old welds ect. All small items have been removed (dash cluster, glove box, def vents, emblems. lights ect) On a positive note though after much convincing (mostly with a hammer )the 5 stuck delivery valve plungers are loose and the engine runs! So don't think I'm just in it to cut them up. I've got 5 other old Macks that need some attention. So these organ doners will live on. Chuck

John The oil capacity for the engine and the filter need to be added together. If you remove the plug from the top of the filter housing you can prefill the filter somewhat. Depending on how much you get into the filter if there is only a few quarts left to it's capacity you could put it in the engine. Once the engine and filter have oil in them start the engine and let it idle. Loosen the plug on the filter and let the air out. Once air is out shut down engine and recheck oil level. That is how I was shown to do it if I'm wrong someone correct me. But I been taking care of my trucks that way. Chuck
