D2Denny Posted October 31, 2021 Author Share Posted October 31, 2021 h67st Hope you get your H done by next spring and bring it to the BVH spring show. I'm looking forward to seeing it. I thoroughly enjoyed driving my H. It ran and drove well, the original seat was quite comfortable and with the vent open in front, not at all uncomfortable in warm weather while underway. Not so sure on the driving experience in this G. Its more like large Spam can on a truck frame. Reminds me of the White 1550's of the 60's and 70's. No creature comforts at all.

D2Denny Posted November 5, 2021 Author Share Posted November 5, 2021 Got a question. Have to pull the radiator on the G and have the core replaced. It only lasted 60 years darn... The cab only tilts about 40 degrees so it isn't coming out from above. Does it come out the front after removing the bumper and the grill. Can anybody confirm this? Thx Dennis Quote Link to comment https://www.bigmacktrucks.com/topic/68540-back-in-a-mack-g/page/2/#findComment-482505 Share on other sites More sharing options...
mowerman Posted November 6, 2021 Share Posted November 6, 2021 Sorry I can’t help you without looking at it but that’s what it sounds like possibly just remove the grill and pull it up and out good luck partner.

I would also add a "come along" type winch from the bottom rear of the cab to a crossmember so you can go gently after it overcenters and not rely entirely on the hydraulic system. 1 Quote Brocky Link to comment https://www.bigmacktrucks.com/topic/68540-back-in-a-mack-g/page/2/#findComment-482554 Share on other sites More sharing options...
h67st Posted November 10, 2021 Share Posted November 10, 2021 What you're saying about the one-way jack sounds right...you'd have no way to pull the cab back past the "over center" point if you did take it 90 degrees.

Will need a few other bodies to get it back in though. Will need an upper water inlet neck before going back in. Got an inquiry into Watts on this. Any other suggestions?? 2 1/4" hose inlet, 45 degree angle, 3 1/2 inch bolt spacing I've got 2 G radiators out,ill see if either has the same piece.

Freightrain Posted November 13, 2021 Share Posted November 13, 2021 (edited) Possible to fabricate a new one if need be. Some 1/4" plate and a piece of radius tubing. I had to make a thermostat housing for my Galaxie with the blower on it. No one makes one the way I needed it to fit.

D2Denny Posted November 14, 2021 Author Share Posted November 14, 2021 Larry. Making one is my plan B. Already found the proper size and degree aluminum elbow with a bead rolled in one end. but perhaps Mike will have one.

Lol. About 10 yrs ago(when I still had dark hair), while on a business trip to Mexico.... I'm in the plant office and a couple workers in the corner point at me and mumble something. Come to find out, while I was dressed in my usual attire of jeans, boots and leather coat they said I looked like Chuck Norris. Lol. Now since I'm old and grey my gf says I look like Sam Elliot when I roll up on my harley(like in the movie Roadhouse). Quote Larry 1959 B61 Liv'n Large......................

theakerstwo Posted November 20, 2021 Share Posted November 20, 2021 On the early engine and that maybe old enough to have one the oil passage from the cam brg boss in the block up to the top of the head supping oil to the heads for the rockers was a cast passage about 3/4 of a inche in diameter.This casting would crack sometines and leak oil out and the rockers would get dry.I have seen this done with the out side oil supply to oil the rockers.The newer 673 engines had a different casting and i think it was steel pipe coming up.

Joey Mack Posted November 20, 2021 Share Posted November 20, 2021 Glenn,,, I am currently building my first ENDT 673... Ive built a few E-7's and a bunch of E-tech's of all series'... I will use this post for info, because if I remember right, the push rods do not have oil holes in the ends.. so it makes sense to me, if someone would add an oiling system to keep the top lubed with an extra flow of oil... I may add this to the engine... was there any issues with too much oil being delivered to the heads, and it pushed out of the breather?

Brocky Posted November 20, 2021 Share Posted November 20, 2021 It must have had a smaller orifice in the valve cover to maintain oil pressure in the engine????

theakerstwo Posted November 20, 2021 Share Posted November 20, 2021 The oil on the valve cover goes thru it and connects to the rocker arms inside.If you remember a Y block ford had the came problems and a out side oil supply was done the same way.The factory oil supply to the top of the block could be seen by removing the side plates on the engine. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/68540-back-in-a-mack-g/page/2/#findComment-483173 Share on other sites More sharing options...

theakerstwo Posted November 21, 2021 Share Posted November 21, 2021 The factory procedure for this repair was to remove heads and they supplied a thin metal tube that you would push down in the oil hole in top of block till it bottom out and a tool was inserted into the tube to roll it out and that would seal the crack in the cast oil galley.I was involved in maybe two jobs like that. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/68540-back-in-a-mack-g/page/2/#findComment-483211 Share on other sites More sharing options...
