gaskets valve cover for 673
davehummell replied to davehummell's topic in Antique and Classic Mack Trucks General Discussion
I got things taken apart and the lower gaskets that go between the block and jake spacer plate were good. I glued the rubber gasket on the spacer with the green cat cement. Both rubber gaskets that went between the jake spacer and the original valve cover were split lengthwise that was were the oil was coming out. I think there is too much pressure on the top gasket and it is splitting them. I'm going to do an experiment and try a different way of sealing the top cover. -
Rob thanks for posting that bit with that little girl acting like she needs more Valium. I understand her pleas but is it genuine? or a paid put-up job? I really enjoyed that commentator setting things straight. I watch the cars hauling one kid at a time out to the school right behind the bus that we all pay for so the kids can ride to school. There is a semi private park out at the end of my road and on the weekends there is three or four soccer games and they are from down in the city I was told most of the kids don't play outside during the week and I guess they can't play anymore without the parent's telling them how to play. Boy are things different than when I was young I was always building a tree house or crawling around the rock ledges in my back yard or playing with my matchbox trucks. we played army, cowboys and indians and made rubber guns and slingshots we all lived and made our own fun. Everyone that I hung around with didn't know jacksh-t about the green earth we just wanted to be kids. I may be an old sh-t to young people now but I bet we had alot more fun back then.

B-73 Restoration
davehummell replied to mattb73lt's topic in Antique and Classic Mack Trucks General Discussion
If I was close I would come over and have a good time helping you bolt all those nice clean parts on a nice clean frame way better than trying to repair a part on a truck or machine with five inches of grease and dirt covering everything. -
Back in the dark ages Detroit diesel made use of two part pistons if I remember correctly they were for city bus usage.

I have had the pleasure of working on the same model tractor with the sh-t bucket loader frame and the front mount dist. is a real pain to adjust the points. I had a 52 it had a side mount dist. way easier to mess with the points.

I am retired now and I don't think I could work for anyone anymore I think retirement was the best thing that I did for myself in a long time. I hope you find happiness in your retirement Other Dog. -
I remember back in the 70's a company was advertising spring shackles with roller bearings in theory that design was not an ideal setup roller bearings are made for 360 rotation think like the bottom end of a harley. That clutch shaft should do quite well with the bushings and good grease and if you want to get carried away you could cut some grooves for the grease to get out in the bushes if you get a tight fit on the shaft. Remember true 660 aluminum bronze is very hard and tough.
-
If someone would bring that assm. to my shop I see two different repairs weld up the worn shaft with my 110 lincoln mig and throw the shaft in the lathe and turn it down it would work for years if you greased it or get some 660 bronze bushings made up and leave the shaft alone and grease the crap out of it if you were really fussy after you cut down the shaft you could caseinate the outside it would be hard for the rollers.

I had a good friend that would preach get us out of the un and that was 15 years ago I did wonder about his thought prosses then but I now realize he was wiser than many others I knew then and now.

davehummell replied to SkippyMack's topic in Antique and Classic Mack Trucks General Discussion
I am happy to see your son in the shop with you I didn't get that opportunity in my youth my step dad was all about sports and I was all about anything with an engine. -
Larry did you get the wrench out and back of the nut on the pump? I am thinking of letting a little more fuel in I have a pyrometer in the dash to watch.
-
Larry after reading about your truck I slid in a rear out of a freightliner air ride I wish my truck was a little longer wheel base I think it would help. Is your tranny a 15 or 13 I ended up with a double over triplex and a 3.90 rear I could of lived with the 4.64 rear I had.

You were lucky I went to two different injection repair shops and called all over the place and I found no help on my old 673 pump and injectors. I finally tracked down Keven All and I bought good parts from him. Your truck is looking very good. -
Briggs & Stratton files chapter 11 bankruptcy
davehummell replied to kscarbel2's topic in Odds and Ends
I wonder how much the wages were in the top floor offices? It seems ceo wages and stock options have a way of altering company's bottom line along with the retirements that were given out when the economy was more stable but now? Briggs use to be a good engine but my cousin and a very good friend both ran small engine repair shops and they agreed any Briggs didn't have the longevity like Honda or Kawasaki. -
Engine colour

Every 675 engines were I worked at years ago were mack gold. I found my local napa dealer had the early d.d. green on the shelf in spray bombs'. -
I had to put down my skippy two months ago. I had him for 14 years and he rode with me every ware all the parts places my truck dealer had treats for him. Really tough job for me to deal with. I know first hand the heart break.

Larry I just looked at your video on facebook nice job. I was setting at my desk and I was reaching for the hot stick.

I worked at a truck company and they had 37 f's and r's and one b for the yard. There were mack 675's torn apart every week never had to repair a maxi 5 speed and I never repaired any mack rears just changed springs and bushes for the suspensions. My boss clamed they got only 100,000 miles out of the mains and rods. I don't know but I changed a lot of bearings at that garage. One guy did coast to coast with a f model with a juced up 237 5 speed. That was so long ago I wish I could remember all the stuff bosso did to those engines to get more out of them. A year after I left the owner bought a bunch of freightshakers with 3406's and began retiring the macks.

I got lucky and ended up with a 260 hp. engine and I put a double over triplex behind it with a 3.90 rear it runs pretty good.
-
I'm no expert but if you didn't use the intercooler I think you would loose some hp. I don't think you would have to redo the pump settings for a truck just for shows. I was hot to buy a 285hp. out of a r model but it turned out the engine was stiff from setting so I got a different engine I knew I would have fun running the second air intake. One of the easiest engine swaps I ever did was installing the later engine in my b.

That 4300 look like the same model I had to keep running for my boss 350 cummins 13 sp. back in the dark ages the truck would of been a good one but it was run to death and put away wet by the time I got to it. If I remember they had a good size cab.

Aussie Truckin' Pics..
davehummell replied to Hayseed's topic in Antique and Classic Mack Trucks General Discussion
That looks like me when I was told to back in a persons side yard with a dump trailer full meaning over weight load of rock dust bedding and the tandems sunk down over the axles on my trailer I used the 580 and the 930 to get the stuff out of the box so we could get the trailer out of the guys yard. I told the boss that it was going to sink but he knew better. I only made one load that day. The other triaxle driver was told watch out for the guys septic on another yard and the first time in he hit the lid and put the wheel in the tank. We had real beauty's back in the day too.
