shanes Posted September 21, 2012 Share Posted September 21, 2012 HiI'm looking at buying an old Superliner, but it has a bit of frame rust.I didn't think it looked too bad, and intend to pretty much completely strip it down and sand blast it.Should I split the inner and outer rails ?What do you guys reckon ? Too much work ?Thanks for any advice Quote Link to comment https://www.bigmacktrucks.com/topic/27445-superliner-frame-rust/ Share on other sites More sharing options...
MACKS Posted September 21, 2012 Share Posted September 21, 2012 From what I can see in the pictures it looks pretty good,no spreading between the rails,if it's just surface rust it's no big deal,you'll be able to clean it up and paint it.

Lmackattack Posted September 21, 2012 Share Posted September 21, 2012 yea its the spreading of the rails thats the big concern and hard to fix. surface rust is easy. However if its seeing rust on the surface I will bet that its started inbetween. it would be smart to put some POR15 in and let it soak inbetween to slow the rusts progress.Just my .02 Quote Link to comment https://www.bigmacktrucks.com/topic/27445-superliner-frame-rust/#findComment-138665 Share on other sites More sharing options...

phildirt Posted September 22, 2012 Share Posted September 22, 2012 Slathering POR 15 between the rails will just make it harder to do right.The only way to fix it right is the hard way- separate them-- Quote Link to comment https://www.bigmacktrucks.com/topic/27445-superliner-frame-rust/#findComment-138863 Share on other sites More sharing options...
Dlock13 Posted September 22, 2012 Share Posted September 22, 2012 You can clear up a lot of the rust between the rails by using an air hammer. You'll be surprised how much rust will come out between the rails. Get some good ear and eye protection and have at it.

rsb502 Posted September 23, 2012 Share Posted September 23, 2012 I am on my second RW double frame and both had surface rust however I never have spread the rails to get it taken care of inside. I plan to paint the one I have now in the next couple years and will probably take the frame apart and do it right at that point but a big part of keeping the double rust at bay is to just keep it dry, park it under cover or use a tarp over it and you can slow it way down.

phildirt Posted September 23, 2012 Share Posted September 23, 2012 I have seen 2 double frame trucks with a row of zerk grease fittings down the center of the frame rail about 18" apart. Pump the grease in and slime the rust.Sloppy but seems to work.

Vladislav Posted September 23, 2012 Share Posted September 23, 2012 I also meant about grease fittings, maybe not so bed idea.

Dlock13 Posted September 25, 2012 Share Posted September 25, 2012 When we built our triple frame wrecker chassis we drilled the outer and inner frame rails and tapped it for grease fittings about every 12" or so depending on the location of brackets, suspension hangers, etc.. It has been on the road for 5 years with zero rust build up that we can see between the frame. Once a year we push fresh grease through the rails. On our recent rollback build, out of a 79 R model, I split the rails one side at a time while supporting the cab and engine/ trans. Used Eastwood rust convertor and rust encapsulator then top coated with a good high solids paint. I drilled the outer rails for grease fittings as well. It works great for us.
