Do thimbles usually get the same torque as their hex nut outers? I've seen my 5 ton thimbles permanently distort when torquing them down and that doesn't seem right.

Finally finished flushing and flushing and flushing my radiator and replaced all straight hoses. Only found a "little bit" of scale inside...

So nice and shiny! Looks like Christmas come early this year :)

Where can the SCA be found outside of truck shops? My NAPA doesn't have it.

Will, thanks for that info. So this NAPA stuff is a pinkish color and does mention an extended life of sorts so I think I'll steer clear of it. The Cummins stuff sounds nice but is a bit on the spendy side.

Found the culprit to the rear head not shutting off right away; broken inner control valve spring on cylinder 6. New spring | old spring (cyl. 5) | outer spring Cylinder 5 spring | cylinder 6 spring

Just to confirm: we should be AVOIDING the low silicate, wet liner formulas? I'm about to start by coolant system flush and I was eye-balling this stuff: @simp5782

I think there are 3 bolts that you loosen to loosen the fan hub and then there is another bolt kind of between the alternator and the block below the water pump that points in toward the block and has a large jamb nut on it. Back off the jamb nut and then tighten that bolt and as it tightens it...

I've been reviewing the video of my test trip and I notice that the jakes shut off properly when the RPMs are 1500 or above, but when the RPMs are less than 1500 I get the hesitation for the rear head to shut off. The manual button on the solenoid never stuck in the down position so I'm leaning...

Thanks for the compliments - much appreciated. I know before the surgery on the hood was a big deterrent to quite a few folks but the hack & whack on a valve cover is far less scary. I imagine M818s are more likely to need jakes than cargo variants like mine, but my jakes are mostly for fun...

So on my setup LO is front and rear heads and HI is all 3 heads. Since I wanted to use a rotary switch that limited me to 2 circuits versus the 3 circuits that a jake specific toggle switch would give you. Since others have said 1 jake head doesn't do much I didn't feel bad skipping that one...

I took my Jake-equipped M813 out for a test run yesterday and it was sweet! The LO and HI work very well and it's not too loud with my H-161 headset on :) My issue with the rear head not shutting off immediately has returned so I'm going to look at the inner springs on the control valves for...

I turned on the power (12V) and I took the test light to each power junction in sequence to make sure each leg of the circuit was sound before I let the voltage flow to the next point: battery ‐>relay->clutch switch->throttle switch->rotary switch->LO circuit->HI circuit. No smoke escaped and...

Well, the jake brakes are now wired up and ready to get tested. To see the full wiring details go to my other thread here: https://www.steelsoldiers.com/threads/trick-functional-jake-brake-grenade-shifter.189934/page-3#post-2274120 For now, here are some finished pics!

The wye connector handles the LO setting (front & rear heads) so one wire loops back around and joins up with one of the HI wires and same with the front head. I'm really impressed how the male rubber cover worked out! Looks very clean and pretty close to what factory wiring could've looked...

I finished the wiring from the firewall to the jake heads today! I made some 10 ga. standoff brackets welded to 1/4" thick spacers to hold the wiring along 4 valve cover bolts and used flange head bolts to attach. Under the first bracket is a 3/4" and 5/16" p-clamps to hold the wye connector...

Actually, when bleeding them I noticed the center one sounded different than the front or rear (higher pitched). I figured it was to do with the firing order but with 1-5-3-6-2-4 it looks like the 1st head (1 & 2) have three cylinders firing between them, the 2nd head (3 & 4) have two...

I would like to have a spare solenoid if you round one up sometime. I was able to get the rest of the air purged out and now all 3 Jakes function as advertised :) All 3 valve covers are bolted on and I just need to reattach the draft tube, the filler cap chain, and the wiring brackets I made...

That's good to know. Do you tend to turn them on after sitting and get them primed so that they're ready when you really need them?
