radiopaulie Posted June 7, 2015 Report Share Posted June 7, 2015 Picked up this 1973 recently in Tucson, Arizona. Appears to be a one-owner truck, with 90K miles. Runs, drives, and stops, but is very tired. Immediate plans are to go through the motor, new shocks, tires, windshield, and lots of other things. I'm not sure if there is more play in the steering, or in the gearshift! Original color appears to be red, with a metallic blue re-spray at some point. Looking forward to learning as much as I can from the forum! https://www.flickr.com/photos/133764436@N05/shares/rt6627 2 Quote Link to comment
datzenmike Posted June 7, 2015 Report Share Posted June 7, 2015 Hi Paul and welcome to Ratsun. 620 speedos only go to 99,999 before 'rolling over' to zero. It's not unheard of for a maintained L series engine to go 190,000 miles though. The transmission shifter looseness is well known and aptly named the 'Monkey Motion' shifter. It just means the rubber cone bushings are worn or the linkage below it needs a washer... usually both. Steering ratio on the 620 steering box is about 19 to one so if all the parts... wheel bearings, (4) tie-rod ends (4) cross link (2) steering box... have a combined looseness of just 1/4" the wheel will have almost 5" of aide to side slack. One of the first things is to get all the fluids changed. Usually after the third or fourth owner the vehicle is old and second hand enough the current owner just ignores the maintenance. 1 Quote Link to comment
radiopaulie Posted June 8, 2015 Author Report Share Posted June 8, 2015 Thanks for the info, King Rat! The link on my post will take you to some photos. You'll notice my ignition switch hanging under the dash. That's definitely a priority fix - though the truck fires up fine. I'm also thinking 2 or 3 inch blocks in the rear, re-indexing torsion bars, and maybe some 195 65 14 tires. We're fortunate here in AZ, with no snow or salt. There's a bit of surface rust, but that's it. 1 Quote Link to comment

Charlie69 Posted June 9, 2015 Report Share Posted June 9, 2015 Welcome. Contact Gene Knight in SW Phoenix. He bought all My 620s and parts. He has a bit of a hoard of parts. http://community.ratsun.net/user/588-gene-knight/ Quote Link to comment
radiopaulie Posted June 22, 2015 Author Report Share Posted June 22, 2015 Notice in the photos that the PO installed an electric fuel pump. Is going back to mechanical as simple as replacing it, and disconnecting the electric one? 1 Quote Link to comment
