Craig N Posted August 8, 2023 Author Share Posted August 8, 2023 Figured out the speedometer wiring last night. It’s a Stewart Warner so the instructions were online. I have to find the port on the back of the transmission tonight. I might wire up a reverse light switch off the dash just to have for inspections and what not. Have to figure out why my directionals don’t work when my lights are on now haha. Looks like it’s going to be a pain to get the compressor out. I wish I had the foresight to do this when I had the motor out haha. Looks like the exhaust and oil dipstick tube will have to come out at the least. I have that motor sitting on the ground so at least I have an idea of what needs to be done. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/22/#findComment-536577 Share on other sites More sharing options...

HarryS Posted August 9, 2023 Share Posted August 9, 2023 I just finished replacing the compressor. I had to take the dip stick out but not the exhaust. I did take the fender off. Made it a lot easier. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/22/#findComment-536699 Share on other sites More sharing options...

Power Brake Sales in California will rebuild mine, but they don’t have one to sell me. I’m on the other coast too, so wouldn’t mind finding someone closer to rebuild mine if possible.

Had drained it prior to leaving too is the compressor on it now from original engine or was on donor engine from start? with the system COMPLETLY drained down, open all tank drains overnight . some cases larger drain if you remove drains completely from tanks, take off the feedline from compressor at the tank end. secure the end so it doesn't go whipping and hurt some one ;; and start engine . see how much crap comes out . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/22/#findComment-536709 Share on other sites More sharing options...

I’ll take the line off tomorrow and let it pump out. This is the compressor that was on the donor engine. Was built in 1989. The one on the original engine is from 1960. Can’t even find replacement numbers for the 1960 one. The 1989’s numbers still exist. Both TU-Flo 500’s, but the old one is obviously an older model.

I was lucky Power Brake in CA had one on the shelf for $900 which included shipping to VA and a $200 core charge. Shipping the core back ate up about half the credit. This place in Pittsburgh, PA rebuilds them: https://www.powerbrakex-change.com/productdetail.php?id=4257. There is also a place in far SW VA which was recommended by Power Brake in CA but there rebuild time was kind of open ended. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/22/#findComment-536727 Share on other sites More sharing options...

So, I just pulled the line off before the air cans coming out of the compressor and there’s no oil coming out of it at all. A little bit of moisture, but no oil. I still have the donor truck and there is no signs of oil in the air lines or in the air tanks, so that’s a good sign. The truck that I’m driving had the original brake chambers chock full of oil, so I’m going with the old compressor (1960) on the old motor was shot and leaking oil by. I think I just need to work the oil out of the complete system on the green one and will hopefully be good to go. It builds air quickly and brings it right up to 120 before the governor kicks in. Good news for sure! 4 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/22/#findComment-536733 Share on other sites More sharing options...
Craig N Posted August 11, 2023 Author Share Posted August 11, 2023 So, my old oil gauge (Stewart Warner) was filling up with oil and I replaced it today with a new one. Now the same thing happened with the brand new one. Filled right up. What the hell am I doing wrong? The fitting screws right on the back of the gauge. No leaks from the fitting, but the oil actually starts filling up the face of the gauge. Can dump it out the light socket.

mrsmackpaul Posted August 11, 2023 Share Posted August 11, 2023 Maybe your doing the gauges up to tight and cracking them inside You could wash out the air tanks but I wouldn't worry about it, the mushroom sauce is in the system now and has been for many decades So if any rubber ware is gunna be stuffed from the oil it's well on it's way I would just drain the tanks regularly at first, every few hours to begin with, or every time you take it out, which should be done anyway at the end of each day you drive it Paul 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/22/#findComment-536779 Share on other sites More sharing options...
