He was listening to a Walkman player and took down two freeway signs before someone caught his attention to stop. Needless to say the company banned headphones after that. If you have a stereo cranked up it would have the same effect. They do the same thing with dump beds and excavator booms. I have seen it.

Popular Post 66dc75 Posted April 30 Author Popular Post Share Posted April 30 So after 5 years I'm going to get back at this (can't rush these things). Started to cut off the ugliness on the back. Not a lot of frame beyond the rear spring hanger and the pintle hitch is pretty awful. I've been thinking of getting an air ride cutoff and upgrading to hub pilot although then I'll have to do something with the front to match.. it would be nice to get the gearing to around 3.70 to get more highway friendly. Got a couple of toolboxes on the shelf that will fit behind the cab nice. Also time to ditch the air assist and put on the power steering that's been sitting in the toolbox since I bought it 7 years ago. 4 1 Quote Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-574811 Share on other sites More sharing options...
mrsmackpaul Posted April 30 Share Posted April 30 I would of thought a spoked/spider axle would be easy to come across with a good ratio A rear axle off a bogie drive I would think would be a give away type of deal just about Paul 2 Quote Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-574820 Share on other sites More sharing options...

I actually would like to keep the spokes. It would be a whole lot cheaper and I am a cheap bastard. It would be nice to have airride though. 4 Quote Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-574830 Share on other sites More sharing options...

Brocky Posted April 30 Share Posted April 30 I like your idea of upgrading the pintle hitch area.. Will you need to add air glad hands?? You will probably have to attach your light bar / mud flap hangers to the end of the frame.. That Goose neck ball looks a little far back for good weight distribution??? 1 Quote Brocky Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-574861 Share on other sites More sharing options...

Gooseneck ball is going away, it's set up for electric .brakes which is OK since all my tag trailers are Electric. Gonna bend up some diamond plate fenders and wi incorporate the lights and mudflap hangers into the fenders. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-574880 Share on other sites More sharing options...
66dc75 Posted April 30 Author Share Posted April 30 When I bought this from Tom Amaducci he gave me a power steering setup for it. Anybody know lf the pump bolts onto any air compressor? The pump came bolted to an old compressor but the one in the truck looks like a fairly recent replacement. Also looks like the dipstick tube is occupying the same space as the pump but I think it can be reshaped.

66dc75 Posted yesterday at 07:12 PM Author Share Posted yesterday at 07:12 PM Whoever built this toolbox / deck plate/ dance floor had to be a sociopath or an utter maniac. C channels welded to the frame flanges then the whole thing was built on the truck so getting it off means cutting it up into little pieces. Actually happy it's coming off the more I look at it the worse it looks to me. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-575233 Share on other sites More sharing options...

Freightrain Posted 3 hours ago Share Posted 3 hours ago A short wheelbase doesn't get much help with air ride. When I lengthened mine 5 ft, it really took the short, bucky ride out of it. With no trailer, mine still rides rough with no weight over the rear. Quote Larry 1959 B61 Liv'n Large......................

66dc75 Posted 2 hours ago Author Share Posted 2 hours ago I'm probably going to leave well enough alone with the rear suspension. I know a guy who filled a tray under his deck plate with concrete, may I can come up with some plate steel for weight Quote Link to comment https://www.bigmacktrucks.com/topic/60610-time-to-fix-up-the-r600/page/3/#findComment-575330 Share on other sites More sharing options...
