I got on Onanparts.com and parts are sketchy at best. Could get real pricey if I have to do valves and guides. Might be able to fudge some of it? Not sure I want to tear into it?

I used to frequent that site. Two pistons/rings won't be too bad. Machine work these days is not cheap. My friends shop where I get all my stuff done will help in costs. I rebuilt a 10hp Kohler in my old Cub cadet for basically nothing but piston/rod. They even balanced it for me and ground the valve seats for new valves. I suppose I could check prices on parts and go from there. Only real wear part is the points and they don't have electronic conversions for the older BF models. I just put points in it this past fall. Like $50? Geez. Need to check slip ring also. Makes good power but you never know if it is near the last leg. Ive always wanted to find a diesel version so I could just run off truck tanks. Buddy build me a 12 gal gas tank to hang on truck.

I've got an Onan 4k rv unit hanging on the B for trailer power. I never have got a cord made up to backfeed the house for the day I might need it. I wouldn't mind finding something a bit larger for permanent house duty. The 4k does well enough for the trailer a/c or microwave. The motor runs okay, but being a 1978 model, it does use oil a touch. Love to rebuild it but likely too costly and better off getting a cheapie Harbor fraud model like everyone else?

It never hurts to ask. That's how I got my B. Owner been asked plenty of times but it was my lucky day and I got it. He threw me a reasonable price and I agreed to it.

Rear axle, swap it( add air ride too). The front will take more effort, depending on what axle it has. Like my axle(FA517) has no budd hub that can swap to it. Been there, tried that. Not sure about the lighter front axles. Finding a B model budd front axle is slim pickings unless you get lucky.

Hard to see the picture. Maybe the nut is there but the sleeve was broken off. Should be able to unscrew the threaded nut easy enough.

Zooming in you can see the notch for the tab on the cable. Likley the cable broke and was just taken off?

Tach drive. I aasume the tach on the dash does not work. What is the black tube hanging in the front of the picture? Looks like a tach cable.

My thread is 1.125. the nut is about 1 7/8" hex. Here is the whole drag link assembly hanging on a spare box I have. It is the same as what is on my truck. I had to swap everything to get the air assist bolted up. Apparently the air set up came from a lighter front axle and the joint at the spindle was not correct. I have the FA517 axle.

Ya, bit nip here last week in NE Ohio. Be 55 on Friday! Watched a YouTube channel the other day. He showed the thermometer at -50*. Yowza. Took some finesse and lots of heat to get the ol highboy running! I remember back in the mid 80s, my 70 f100 and the slow start running 20w50 oil and the transmission having 85w140 in it and would stall the engine if you engaged the clutch. Fun days!

I have the pitman arm off my B when I converted to air assist. I don't know if they used different splines? Diameters?

Easiest way to post a video is use Youtube and paste a link. This forum does not handle large downloaded video files easily.

Translation: "I have a Mack F763ST truck from the year 1972. I need a technical sheet for this vehicle. If someone can help me." Are you looking for engine specs? Chassis? Transmission?

NE ohio is supposed to get it early tomorrow morning. Owner gave us the extra day off so don't have to deal with getting in through the supposed mess that is coming. Then off til Jan 3rd.

Ya. All back to "abnormal" LOL! Got to sleep til 6am. Wahoo!

I've been through a few times. I do travel randomly for work. Pretty painless trip this time other then having to get up at 3 am for two days to get to the airport.

Morning Dan. I'm currently sitting in Atlanta airport waiting on my connection flight back home. Up at 3am again this morning. Ugh, can't wait to get back to normal schedule tomorrow.

Prerty sure that is all Dans handywork! "High binder".......biggest understatement EVER! I get a nose bleed just looking up at that cab. Lol.

Gregs is Blue and silver

Looks fantastic!

LOL.....

My mother tried to plan her death down to the letter. Too bad it doesn't work that way. 3 yrs in nursing home, she was miserable and just wanted to be done. It was a relief for all of us on that final day.

Ya, Greg is still running that old MH. Met up at Harrisonburg, VA convention. Saw him after you saw me over the fence Brocky! He was parked down the aisle from me, towards the campgrounds. Ya, he gave up on the old Mack powerplant after it failed the second time. It's now a CattyMack.....LOL.

I met him in jr high. He went to different high school, then he joined the marines and didn't keep track of him until I saw him here. We chatted a few times through the years and I would run into him at the Dover steam show in Aug.
