JoeH Posted January 28 Share Posted January 28 What causes the steering wheels to crack? Is it UV? Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-545722 Share on other sites More sharing options...

mowerman Posted January 29 Share Posted January 29 Yeah I don’t know what it is either. I had one crack on me. I just happened to have my hand right on it turning a corner and it cracked right under my hand. It wasn’t even that hot out it was a white 9000 way way back long time ago.

Freightrain Posted January 29 Share Posted January 29 Raneys has some retro steering wheels available. I've been contemplating getting one for my B. Likely better then trying to restore my old wheel. Once the steel core starts to rust, it will distort again and crack.

mattb73lt Posted January 30 Share Posted January 30 Age mostly. As plastic ages it becomes brittle and actually shrinks. Then add the UV's, solar heating, hot and cold cycles and someone wrenching on it all day, cracks will form. If you watch some, you'll see gaps opening up where it's cracked. Plastic is a petroleum product and "off gasses" as it dries and cures. Hence the PVC smog that forms on the inside of you cars windows and the New Car smell it has when new. Then it smells like sweaty man ass, fuel, oils and exhaust after a while. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-545855 Share on other sites More sharing options...

Popular Post JBushneck Posted January 30 Author Popular Post Share Posted January 30 Was able to get the cab in position. Still much to do but on track to finish by May. Waiting on cross members and fuel tanks to come back from sand blasting shop. Plenty of small things to stay busy on. 5 Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-545871 Share on other sites More sharing options...

Popular Post JBushneck Posted February 6 Author Popular Post Share Posted February 6 Went to Florida for the weekend so didn’t work on the project until after work today. Was happy my crossmembers were finished when I got home so I was able to install them and remount the spring hangers and springs. Finished the day with some paint on the back of the frame. Next step will to pull the rear back under and remount and then if weather is decent over the weekend put some paint on the cab. 5 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-546177 Share on other sites More sharing options...

mowerman Posted February 12 Share Posted February 12 I was kind of wondering that myself why he had the rims on it??????? Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-546530 Share on other sites More sharing options...
Popular Post JBushneck Posted February 12 Author Popular Post Share Posted February 12 This Mack is not going to be a slammed rat rod. I have it on rims so I will be able to get It out of the garage. When finished I will put the 11R-22.5 tires back on. The disadvantage of only having an 8’ door is I’m limited to project size and have to get creative. To skydawgs question-I’m by myself. No other help on this project. 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-546531 Share on other sites More sharing options...
mowerman Posted February 12 Share Posted February 12 Oh gotcha I guess none of us thought of that. Looks like you’re gonna have the fastest truck restoration in US history you could start your own TV show like those mechanical rock stars ha ha.

mowerman Posted February 24 Share Posted February 24 We must’ve missed something. Why was the engine in New York? Is it a different one than what was in there thanks for the update….

Popular Post JBushneck Posted February 24 Author Popular Post Share Posted February 24 2 part answer to your question. The truck was in NY at my fathers and I have been bringing it down piece by piece as I assemble it. I have decided to put a newer engine in it with a Jake Brake. 4 Quote Link to comment https://www.bigmacktrucks.com/topic/73700-74-mack-rmodel-project/page/3/#findComment-547073 Share on other sites More sharing options...
