I find it interesting that the steering shaft slip joint that is under the dash in an American R Model, is at the steering box. Although, I dont see the steering box, just assuming..
the shaft is install backwards to what I'm use to???

Don't be afraid to put some brakes on while driving it hard ! Road dyno it ! Put boost gauge and pyro in and drive by them!

There is oil getting to the heads, but it is the rocker tips that seem to be marginal at best. A few have oil drooling out of the rocker tip. Most basically nothing. Granted there is not much spring pressure, valve lift or RPM that would wear the rocker faces. I always question it because on a gas engine if you have the valve covers off....you are getting soaked even at idle.
I would personally run it for a bit before getting carried away! Get the engine in the truck and work it hard the best you can I understand its a toy but you don't want to baby a new set of liners and rings You need to warm it to operating temp then and work its ass for the first bit preferably loaded! Nothing ruins a rebuild faster than idling to long!
Just sayin!

Is it a sheppard steering box. I think you can leave it mounted, and pull the sector shaft out to replace the rear seal. Its been a while for me..
on a Shepperd there is a also a weep hole on the cover ! you can tap it out 1/8 pipe tap and put a plug there it would hurt any thing ! If that's where the oil is coming from!

Dunno about the valves and the amount of oil
Joey or Geoff will know, I just set the valves and send it, yeah I'm not super anal
Paul
You should be ok with the oiling in my estimation ! have you tried the jakes? that will tell the tail if enough oil is getting up there! push the solnoid down see if they fire off!

I have been told the Volvo cabs are very comfortable and spacious, so there is a plus to the redesign. I haven't really been inside one to form my own opinion, only parroting what I've been told by my techs!

Closing off the back end will help as well as keeping debris from blow in. Cables in an X with turnbuckles to tension will do a good job as well. Closed back end with X cables would be the best.
short of building a real wooden structure ! this is the best option in my book!

😂 no tin foil, but I had a CH that looked similar to the blazing away pictures. I was lucky and got it out though.
We had a bunch of trucks they sent out a bunch of bandaid kits out ! What a joke! that it only happened for a short time! THENI think some one told them to fix it Or ESLE ! NO BANDAIDS! Guess they found a new line supply ! They also tried to blame us wrench Guys! Makeing us do a fuel line tightening coarse ! I was super piss about that! Just my take on the fiasco! Just Behind the blinds drama!

On the four Valve in true Mack fashion they started transitioning the engine to E7 block by practicing with the e6 changing the front cover to aluminum and adding a front mount that had pads instead of the trunnion mount set up! there were other subtle changes but that was the most noticeable! That dimensions are the same mount to mount !
Joey I Can't imagine you embellishing anything😅 Simply stating what you believe to be true just like the rest of us!🙏

That was usually the result of a broken injector line.

Mark were you ever involved in the fuel line bandaid putting the tin foil sheild on the lines? What a joke!

Front mount is the real only issue!

Minimal! If you have an e6 4 valve the mounting is identical!

Yes, that is the reason I posted that example.. it is more forgiving then the solid types..
most folks don’t understand the use of the clutch brake so yup I agree with that choice! Myself I would use a two piece eaton brake but the set has to be perfect! If you don’t set and use techniques correctly you can ruin them with one poke to the floor! Don’t ask me how I know!😡

Seems like mack and John Deere are about the only 2 companies I can think of that really didn’t have their engines in anything besides what they built. Kind of a shame since it seems the L10 Cummins was a flop from what I’ve heard and think the e6/e7 could have been a good fit for an alternative. Just a thought I had. I enjoy reading about management history of these companies and deals that happened behind closed doors
the e9 was used in tanks at one point From what I have heard!
