Popular Post Rob Posted December 22, 2019 Popular Post Share Posted December 22, 2019 Going to reinstall the end sheet metal panels back onto my air compressor and the hardware is pretty crusty. Just prior to going into the basket: Into the basket: 15 minutes later: Lots nicer to not need to fight the rust and dirt that accumulates on 58 year old hardware. While these were being blasted I ran a tap through all the holes these bolts will go into so should zip right together. Compressor is going a few miles down the road next week to depaint a truck/tractor frame and steel demolition trailer. It should get a good workout running two men with each requiring about 100cfm. 4 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Timmyb Posted December 24, 2019 Share Posted December 24, 2019 Will anti seize stop the threads rusting once it’s all assembled? Quote Link to comment https://www.bigmacktrucks.com/topic/60275-15-minutes-in-the-tumble-blaster/#findComment-438737 Share on other sites More sharing options...
Rob Posted December 24, 2019 Author Share Posted December 24, 2019 Timmy, I can't say for certain but that is what I did before running them in this morning. Some of the bolts I did not reuse as they were pitted quite deep meaning about 1/2 through. I replaced them with new hardware. Many of the flat washers were also replaced as they were "dished" from over torquing sometime in their life. All of the hardware was sprayed with cold galvanizing compound prior to assembly to hopefully preclude rust. These panels come off for routine cleaning and filter service so I don't want the fasteners rusting in place. I had to drill and tap several broken ones when taking it apart. This will be painted Mack green with black fenders to match the B-673 when all done but before going much further I need a good functional checkout which it should get next week: Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Timmyb Posted December 24, 2019 Share Posted December 24, 2019 Cool, I did the same on the bolts on the back of my truck last year. Anti seize on them all, glad to see I was on the right track. We have a sulair 185 but it’s not on a trailer. Definitely something I want to build for it eventually. That should look pretty classy once all dressed up.

Rob Posted December 24, 2019 Author Share Posted December 24, 2019 Thanks. It is a 1962 built air compressor as is the B-673, so they should look good together. Hopefully we'll get through this "test" over the next few days and I can move forward with the project. I pulled all the aluminum nameplates off the machine which are embossed "Worthington, Blue Brute, Monorotor 250", and have sent them to a lady whom restores old signage to see what she can do with them. None damaged or pitted but covered in layers of paint. I also sent her a print of the color scheme originally used, so hopefully she'll dress them up quite nicely.

So far really liking it but again it needs a full functional checkout. I make no acceptance of performance degradation citing age on anything as I believe something was built to perform 100% till it's in the grave. I removed the radiator and sent it into the the shop for a new lower tank. They old school "rodded" the core as it was dirty and custom made the lower tank. Thought I had a photo but the lower was split from freezing. Core was fine: Sent the aftercooler in also at the same time for boiling: Continental B-427 engine which runs like a top with a good tuning, carb rebuild, electronic distributor: Lots easier to work on with the sheet metal removed: Had made a jig to lift off the hood which is 16ga. steel sheet and right at eight feet in length: All kinds of busted fasteners getting the sheet metal off too: \ Poor thing probably hasn't seen a day inside it's entire life till my acquistion.

eddeere Posted December 24, 2019 Share Posted December 24, 2019 Nice work. I had an Ingersol Rand compressor on trailer. The compressor worked fine but the continental engine was worn out. I located the same engine at a swap meet in Iowa. The engine was rebuilt by Valley Engine Rebuilders in Cin, OH with all the paperwork and a tag riveted on the block. The price was right and I thought I really lucked out on this. Installed the engine put antifreeze in it started it up and saw antifreeze on the floor. There was a freeze crack in the rear of the block. At this point gave up and sold every thing.

Thanks, Sad to hear that as a lot of frustration and work there. I've repaired Continental blocks in the past that were out of forklifts in both six and four cylinder variants. The coolant passage at the rear is a common place to crack as the castings are very thin in the area. Seen them cracked from both freezing, and overheating in the same spot. I knew this air end was good and the compressor was offered in both this engine, and a Detroit Diesel 4-53 series and have access to one of those if needed.

mackey58 Posted December 24, 2019 Share Posted December 24, 2019 Hell I bet parts are hard to find for a continental engine Quote Link to comment https://www.bigmacktrucks.com/topic/60275-15-minutes-in-the-tumble-blaster/#findComment-438778 Share on other sites More sharing options...
Rob Posted December 24, 2019 Author Share Posted December 24, 2019 Many hard parts are for certain. Best not blow one up or going to be less $$$ to retrofit something. Monte's Equipment in Chicagoland still has a pretty good supply of water pumps, gaskets, and overhaul kits I'm told but I'm sure that is a limited availability type thing. They are getting to be like Hercules Motors parts however for bearings and such. Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
