Timmyb Posted July 15, 2014 Share Posted July 15, 2014 There were a few sections of the chassis that had a bit of growth so we thought we would attack it and try clean it up while we are doing it up. It didn't look so bad, but when we pulled it apart looks a bit worse then I thought. Anyway, I've been working on this for the past 2 days, I'll keep the pics coming as I continue. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/36362-cleaning-rust-out-of-double-chassis/ Share on other sites More sharing options...

j hancock Posted July 15, 2014 Share Posted July 15, 2014 Compared to some double frame rust in the northeast US, what you have is a walk in the park!You are doing it right. To kill it off, you need to take it all down. 1 Quote JimIt doesn't cost anything to pay attention.

Freightrain Posted July 15, 2014 Share Posted July 15, 2014 I remember way back cutting the double rails off my B model. Same thing, rust spreading. Didn't need the additional support anymore anyway. Lucky they started just under cab and came off easily, once everything was unbolted off the frame. Quote Larry 1959 B61 Liv'n Large......................

mrsmackpaul Posted July 15, 2014 Share Posted July 15, 2014 I always find it amusing how depending on what part of the world your from depends on how bad something can look all a matter of what you are used to I guess ?In Australia on cattle trucks they would fit grease lines and nipples (zerks I think you Yanks call them) on blocks some were convienient to force grease in between chassis rails as cattle trailers were normal trailers with crates built on them and all pi$$ and $hit would leak through and get between the rails and rust them reel bad it amazes me when you lot in the states do these rails no one ever fits these grease lines to stop it happening againDid Mack paint between these rails when new ? fair bit of work ahead of you there TimPaul Quote Link to comment https://www.bigmacktrucks.com/topic/36362-cleaning-rust-out-of-double-chassis/#findComment-253021 Share on other sites More sharing options...
Timmyb Posted July 16, 2014 Author Share Posted July 16, 2014 Paul, it doesn't look like there was any paint in between the rails. I'm gonna use some rust kill epoxy paint to prevent it from happening again. I know what you guys are on about, I've seen some pics in here where they have cut them off and welded new rails on. I guess mine is more like a prevention job. What do people use to fill the pitts left from rust? I know it's purely for cosmetics, but I was thinking of using body filler on them.

doubleclutchinweasel Posted July 16, 2014 Share Posted July 16, 2014 What I was told by Mack, is that the rails were primed, bolted together, then painted as a unit. So, no, there would not be any real paint between the rails...which does aggravate the rust problem. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Timmyb Posted July 19, 2014 Author Share Posted July 19, 2014 This is it after it had been chiseled, grinded, wire brushed and sanded.This is after some rust converter.And applying some paint. I'm using white knight rust kill epoxy. Should be better than nothing... 2 Quote Link to comment https://www.bigmacktrucks.com/topic/36362-cleaning-rust-out-of-double-chassis/#findComment-253310 Share on other sites More sharing options...
mrsmackpaul Posted July 19, 2014 Share Posted July 19, 2014 moving right along there Timmyb I would think any bit of rust proofing would be better than none Paul Quote Link to comment https://www.bigmacktrucks.com/topic/36362-cleaning-rust-out-of-double-chassis/#findComment-253313 Share on other sites More sharing options...
Timmyb Posted July 19, 2014 Author Share Posted July 19, 2014 Thanks Paul. Quiet times allow for a bit more work in the shed. I'm actually really enjoying it, although I've taken my time and there is no dead line. I've also discovered a few tools along the way to make the left hand side a lot easier. Having said that, I wouldn't wanna do this sorta job too often.

Vladislav Posted July 19, 2014 Share Posted July 19, 2014 Looks done well.I hope it will work for you longer than original unpained rails.There was written on here about grease fittings before.It seems to me as not a bad idea.Vlad Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/36362-cleaning-rust-out-of-double-chassis/#findComment-253317 Share on other sites More sharing options...
