Popular Post r686st Posted August 8, 2013 Popular Post Share Posted August 8, 2013 Back in April bought the truck and a 1972 Palmer dump trailer to use in my construction business. Since then it's only left the shop once to steam clean it and do some test driving. I've got a small fortune tied up in it but I keep telling myself it's going to be worth it. So far the parts I've purchased: trunnion bushings, fifth wheel bushings, upper and lower isolators, side spacer, torque rods, rear shocks and frame studs with hardware, cab shocks, front shocks, exhaust elbow, stack, exhaust brackets, front axle bumpstop, battery retaining rod, clutch pad, floormats, aluminum foot rest, cb and antenna, 8 recap drive tires, 2 virgin steer tires, 4 aluminum rims for the rear two axles, rebuilt the back axle, fresh fluid and filters throughout, turbo, heads, throttle cable, kill cable, clearance light, steering boot for the firewall, 4 brake drums, 8 brake shoes, 4 spring kits, all new bearings and seals at the rear axles, longer inner nuts, two slack adjusters, 4 S-cams, aluminum half fenders, aluminum hydraulic tank, chrome front bumper, hydraulic pump and plenty more to come. Is there anything else you'll recommend to check before I put it on the road?BTW: The green Mack is my dad's 1987 R686ST. 8 Quote Link to comment Share on other sites More sharing options...
2stacksuperdog Posted August 8, 2013 Share Posted August 8, 2013 Looks good. Cant go wrong with an old R-model! Quote Matt Link to comment Share on other sites More sharing options...
r686st Posted August 8, 2013 Author Share Posted August 8, 2013 Forgot to add that I purchased new spotting mirrors(circle) and new Mack mirrors(rectangle). Also got mudflap brackets for the rear and two Mack mudflaps. I'm sure there is more and I'll add when I think of it or do more work.

Popular Post r686st Posted August 8, 2013 Author Popular Post Share Posted August 8, 2013 Thanks for the advice! The truck had a tough life off road the last few years building pond levees so I'm paying for it now. It's kind of a funny story on the trip home with it... I had no seatbelts, couldn't get the seat aired up, had a long shifter(gorilla shifter), red offroad diesel, no insurance, atleast one canister wasn't connected to a slack adjuster and come to find out the owner had signed his other R model over to me on accident. LOL! 3 Quote Link to comment Share on other sites More sharing options...

r686st Posted August 8, 2013 Author Share Posted August 8, 2013 Ha, funny you should say that... I bought the truck in North Louisiana(Winnsboro) and drove it south home. I was passing through the Natchez, Mississippi area and DOT had a tanker pulled over. As I passed by he strained his neck watching me the whole time:) Quote Link to comment Share on other sites More sharing options...
jakebrake86 Posted August 8, 2013 Share Posted August 8, 2013 That's a sweet ride. When I was 21 I bought my first old r model and rebuilt it. It took me 3 years to put it on the road but it paid off. You're doing right! I've had to do my share of outlawing, too. Must be a southern thing.

r686st Posted August 8, 2013 Author Share Posted August 8, 2013 Thanks for the kind words. Can anyone tell me what the last year of the round headlight R models was? I think it's either '91 or '92 right? Quote Link to comment Share on other sites More sharing options...
jakebrake86 Posted August 8, 2013 Share Posted August 8, 2013 I believe it was '91. If I'm not mistaken the sloped hood RD started in '92. Quote Jake Link to comment Share on other sites More sharing options...
r686st Posted August 8, 2013 Author Share Posted August 8, 2013 That's what I thought. I'm pretty lucky to have found one of the last yr models then. It's frame and cab are in solid shape which is rare but mechanically it'd had a rough life. I'd been looking for a R with a 300 or bigger and camelback so when I found this one I jumped on it.

Green Dash Posted August 8, 2013 Share Posted August 8, 2013 The truck looks great and is definitely worth what you put into it.Thanks for the advice!

r686st Posted August 9, 2013 Author Share Posted August 9, 2013 Looks like atleast new drums and slack adjusters are needed on the front axle. Out the door more money goes.... Quote Link to comment Share on other sites More sharing options...
thomastractorsvc Posted August 9, 2013 Share Posted August 9, 2013 Why did you only replace two on the rear slack adjusters when you did the rear axle brakes? If you replaced everything else but those two I would replace them, then everything would be new back there. Have you looked at front bumpers yet? Mine has a painted bumper vs the chrome, if they get wrinkled they don't look so bad.BTW where did you get the wet kit pump from? I am looking for one Quote Robert"I reject your reality and substitute my own." Link to comment Share on other sites More sharing options...
r686st Posted August 10, 2013 Author Share Posted August 10, 2013 All the other rear slack adjusters were fine so didn't need to change them. I already bought and installed my bumper it's the first picture I posted. The pump came from my dad when he had 10 Petercar's so I don't know where he got it. He told me I was welcome to anything I could use but not a whole lot swaps over to a Mack. Quote Link to comment Share on other sites More sharing options...

NoClueJoe66 Posted August 10, 2013 Share Posted August 10, 2013 That r model will still be going strong while these newer ones are in the junk yardDon't they all?....With all the new stuff done to this one I do believe you should be good for awhile. Don't forget the chrome hubcaps and lugnut covers though Quote This message was brought to you by Hargraves Potted Meat Product.

Just a couple cosmetic add ons I could think of round fender mirrors(very helpful at times) and bumper guide poles with bulldogs on top and maybe a chrome breast plate to go with your chrome bumper .

r686st Posted August 10, 2013 Author Share Posted August 10, 2013 It had round fender mirrors at one time but someone took them off. I haven't made up my mind whether I want to put them back or not. I would like bumper guides and the chrome grill guard when I get the funds. Quote Link to comment Share on other sites More sharing options...
rsb502 Posted August 10, 2013 Share Posted August 10, 2013 Im just wondering why its not working already, it should do fine and you can work on it little by little, let the truck make some money to pay for those parts.

r686st Posted August 10, 2013 Author Share Posted August 10, 2013 The brakes, tires, rearend, motor and rear suspension needed immediate attention so I decided to do everything while it was down. I thought that would be better than trying to get it on and off the road to fix a little at a time. Quote Link to comment Share on other sites More sharing options...
Brandt Posted August 13, 2013 Share Posted August 13, 2013 (edited) Wasn't sure if a '91 was considered a "classic" or modern. Glad it falls into the classic area. I also have a 91 RD 690 S. I found this site while looking for parts. I'm not attempting to hi-jack this thread but I need the headlight assy/bezel/mounting brackets. Blew a steer tire yesterday and when a big floater lets go it does some damage. I never did any fiberglass work but it looks like I'm gonna learn!! If there are some good parts suppliers out there - I'm all ears. Edited August 13, 2013 by Brandt Quote Link to comment Share on other sites More sharing options...
r686st Posted August 14, 2013 Author Share Posted August 14, 2013 Looks like two new front drums, s-cams, slack adjusters, 4 shoes, bearings and seals are in order for the front axle. I found out I'll need kingpins and bushings as well as spring hangers on the rear side of the front axle. Quote Link to comment Share on other sites More sharing options...
2stacksuperdog Posted August 14, 2013 Share Posted August 14, 2013 Look at it this way, youll have a new truck when your done with less headaches then a new one Quote Matt Link to comment Share on other sites More sharing options...
