If I remember correctly the natural aspirated Mack engines did not have the tubes and all the ones I rebuilt had the tubes because after you got done with the new liners, you would check the orientation of the tubes with a plexiglass plate the tubes shot oil up into the underside of the pistons for more cooling when using a turbo. I remember the early 3406 engines had replaceable tubes and Cat recommended them to be replaced at a milage or hours I now can't remember also you rolled in new bearings at some point recommended by Cat. I had a freightliner with a 3406 that the pisser tube broke off and it scored the piston so bad I had to do an in the frame job

Larry maybe next winter you will rig up a power steering box on your B.

I like Macks and currently own a B model but the last place I worked there were two Kw's with c12 engines two Macks with 350's and Western star with a c12 a freightliner with a 400 DD an old Volvo with an old 350 Cummins another Mack yard tractor a Sterling with a c12 an Autocar with a Cummins two single axle garbage trucks with smaller cat engines a Ford rear load with a cat engine and a front load Mack with an mp8 this truck was the most unreliable in the fleet and one of the newest. A cat wheel loader with one of those English engines JD 410 backhoe and a JD 450 dozer and five walking floor trailers and brand-new Case frontend loader that was a nice machine to run. Every week there was something wrong with the pollution crap that was on the MP engine

Larry looking good it looks like the air compressor has a place for a power steering pump on the original 673 in my Mack I put on an air compressor like yours and added a pump it was a job and a half if I remember correctly, it involved me using my one lathe and milling machine and a lot of figuring. So far you gained over 40 hp. on me that should pull your race car very well that same engine was in a Mack cabover that I would pull 100,000 plus gross of bedding for riprap in a steel dump trailer. I wish I went through the aggravation of getting a twin disc clutch but the triplex was set up for a single and I'm usually only hauling a nine-hundred-pound bale of hay for my goats.

Larry I found a triplex and installed it in my B it is double over and you don't split 5th either so in reality it is just a 13 speed

When I was in 9'th grade the school that I attended pushed for collage and people like me were thought of as loser's by not wishing to go to college I decided to attend the local tech school and it was the one reason I did graduate plus I learned some life skills that I have been using for 53 years. Before I was out of school, I lined up a job as a Honda motorcycle mechanic for the day after I graduated and, in the fall, I took a job as a heavy equipment mechanic

Those prechambers on old cat heads were just a nightmare to get out sometimes and yes the injectors on the Mack heads were more times them not a real battle. I used to mess around with the old hit and miss engines and getting a stuck piston out was always great fun.

My one Grandmother and Grandfather came over from Italy and he worked in the mines she was a house wife I never saw any Italian speaking signs up around Pittston if I wanted to talk to gram I had to carry on in Italian everyone spoke Italian in the house but always American off the property no special stuff was expected from them like what is going on today and I bet my Grandfather had a tough time working in the mines not like todays piss poor excuse of humanity today

those bulldogs pulled good money I may have to dig out the one I have stuck away on a shelf and get it in my show case

Mark T what was the pump guy's name that had the pump shop in Dunmore I took the pump off my 673 and he said there was no parts to fix it. On the later engine pump I had an injection pump repair shop out on old RT 15 in Williamsport dropped it off in the morning and went out a day latter for it. Years ago, I worked on a 675 and sent the pump to a shop in Hazelton.

I owned a bunch of old Toyota Land Cruzers the newest was a 1980 fj40 I had a 65 fj45 pickup that I installed a 292 chevy 6 that was heavily modified and a later 4 speed cruzer trans power steering and an air ride seat out of a freightliner I owned an old scout and a jeep station wagon also and an all-wheel drive International 1200 pickup. I now have a ford that you twist a knob for your 4 wheel drive but it does have an electric activated possi rear. For quite a long time I had an M151 army issue jeep the one with all wheel independent suspension it was made by ford if I remember correctly.

When I went to Caterpillar engine school the instructor told us to always hold the liners down just as a precaution those o ring liner seals on 3406's were soaked in motor oil and then you put them on the liner and get the liner in place right away before the seal swelled up I don't think I soaked the o rings for the 1693 engines but that was a long time ago and my memory is not that good any more. I cut a lot of blocks for shimming the liners for liner projection height.

When Fetterman got elected I figured what we just need another democrat, but he has surprised me with the way he thinks I bet he isn't a favorite member of his party he does look like a hoodlum in some of his photos

I bought one of those clear top stoves and later on I replaced it with a Viking gas range I like the gas stove better I have a collection of Griswold cast iron frying pans I cook with about every day I use a number five to cook my eggs every morning

I think all the weird drugs that get shipped in and what they do to people's minds have a definite impact on how society acts so I don't see any problem blasting the drug boats anyway posable. The welfare situation is out of hand anymore with the attitude with some people have a bunch of kids and set on your ass and get paid.
