correct. That's exactly what was done to a m818 in the thread link. I had been planning to do the same thing to my m816 but the tcase pto is different on the T1138 than my T138 and those PTO outputs are pricey.

T1138 is .73:1 in high range. The Allison auto is 1:1 in the m939 series giving a final top gear of .73:1. Spicer 6453 in the m809 series is .78:1 5th gear, 1:1 high range tcase giving a final top gear of .78:1. Not including axle gears. Thats why with the same size tires and same engine the...

Most of the Eaton Fuller 13 speeds have a 12:1 first gear, which is deeper than the 'ultra deep' 10:1 reverse gear that your Allison MT654 has. For reference the 5 speed Spicer 6453 in the m809 series is a roughly 6:1 first gear. Video of my m816 going up a hill at 600-800rpm, 1st gear low so...

I'll have to look at it closer.

Sweet. Will have to replace the end, my current one is bent (double blocked at some point before I got the wrecker). Not sure if I need this one http://products.esmet.com/viewitems/extruded-jacket-kevlar-rope-fittings/clevis-socket-extruded-jacket-kevlar-rope-fittings Or this one...

Hahaha not my property, just where I store the big stuff. The m816, m51a2 remains, m103a2, and generator are mine but nothing else is.

I'm going with Amsteel Blue, different manufacturer but same materials. Not using their top of the line braiding, the second best because even with that it's still much stronger than the stock steel cable. There's a couple companies around here that run the synthetic cable on their cranes and...

Agreed. Between the box and the fact that the 8.3 (in stock form) has no guts until the higher RPM's where the turbo has spooled up then this sounds normal power wise. If the first lap was the same as later driving.

Supposed to clean up and smooth the pulleys whenever new cable is installed, it's more important with synthetic to do this than with steel. So I'll be taking my buffer wheels to polish up the pulleys and a pressure washer to clean everything up first. The 2 downsides to synthetic cable are the...

The future trailer had to be moved forward and my friend wanted to test out the new winch on his land cruiser. Will be happy once this wrecker is mobile again.

Breaking strength on the stock 6x19 fiber core cable is 20-22k pounds. Working load is lower figuring either a 3, 4, or 5 :1 WLL. I'm going to synthetic on mine (yes it's approved for cranes, even available direct from the manufacturer with synthetic for the past few years) with a breaking...

Interesting, mine is setup as 3 part also. Not changing the setup on mine because the cable is old and could use replacement soon.

The standard wreckers m543/816/936 did not have a trolly valve originally. The previous owner installing one and plumbing it into the trucks service brakes makes sense as a 'winch brake'. I agree that the 2 items on the left of the pallet look like a built towbar setup, making it where the...

Pics of the weight ratings on the crane

Picture of the brake hose that I'm using And the grease that I've been using on the truck. Cut the hoses to length and figured out the routing for the plumbing going from the QR1 valve out to the frame studs for the front brakes yesterday. Removed the original T fitting that went from...

Fuel pressure should be checked in 2 spots. First is at the fuel tank, needs to be about 5psi. Second spot is after the final fuel filter with the engine turning over, needs to be 32+psi. It can start/run with only 20psi after the final filter but the engine is under powered at that point and is...

With the fuel making it to the pump, and not out of the hydraulic head (where the 6 metal fuel lines lead out of the injection pump to the injectors) then it is usually because the button came off or the fuel cutoff plunger is sticking inside the pump. Checking the cutoff is quick. Remove the...

When the seals in injection pumps go out the fuel will leak either outside the pump or into the engine oil, but it is never a complete loss of flow through the pump. So yes the word NEVER is accurate in this regard. A mechanical failure yes but seals no. The button falling off is a very common...

Common problem, I think it has to do with the CARC paint since they go for these vehicles much more than vehicles with regular paint. Following to see what you find out.

Reason most of the replacement injection pumps do not have the fuel density compensator is because it is not needed and is prone to leaking fuel into the engine oil. It does not affect the engines ability to run on other fuels (oil, veggy oil, gasoline, etc). All it does is adjust how much fuel...
