I can't see where it might have been altered to that extent, but not having seen one before it is difficult to judge. The spare that arrived seems the same and hte parts Guy ordered it from the VIN number so if that is correct then something else must be different. I am getting to the stage where I need another FL7 to look at. Not sure what else to do. I am pretty sure the cab has either been off and painted completely, or is a new cab. The paint is jst too good and there are bolts all over that are either not matching or new, and telltale paint areas where washewrs are in different places etc. The bit I don't understand is that I got it to lift just once with the original ram and never again, which is why I went wit a crook ram. Maybe I just have two crook rams or they are F10 rams.... This is driving me nuts.

Managed to do a couple other things in the middle of cabamania. Put in the little reversing switch plunger and Hey Presto... nothing, so the dome inside the gearbox must have come off. Have moved the additional switch so it now works, just have to re-dril a screw hole and tighten it all up.
Also, it has 4 tanks... must have had a Blokes look... ;). I sat in the cab and watched the needles and let them build up and waited some more and eventually the Broms button was able to stay in, so I guess you must be right, the valves are in need of replacement.
Also looked a little more at the exhaust brake. When actuated, air just gushes out of the alloy bit on the front of the turbo. Without the cab tilted I can't get it apart, but I guess the actuator part of it is stuffed somehow. It seems to be comng out the side of the alloy fins so I have a nasty feeling that it is cracked.
All in all not a good day for the truck. I think I will work on the boat tomorrow for some light relief.

I have decided that something should be lifting the cab up a few inches when the hooks release, that is the only way it will be able to lift. If you use a lever and lift it manually while somebody is pumping, away it goes. I am thinking it must have the wrong springs in it or something. Maybe the cab is the wrong one for it and the geometry is slightly different. I need another one to compare....

Exhaust brake - otherwise known as "exhaust pressure regulator" - it's main function is to provide back pressure to keep the motor warm at idle and start up. With extra pressure it works like a snake brake (all hiss, not much action.) The finned ally part has a piston in it which runs dry and you might get away with just replacing the piston seal. At times there will be some exhaust coming through the vent holes in the side of it.

The original F86 never had the broms or check valve. It was put in to stop runaways on start up if the hand brake is inadvertently left in the off position (remember it's Euro and the handbrake works on pressure and maxis only operate when the last skeric of air has gone.) If it goes in when you have full pressure and stays in while you go through driving cycle then it is doing it's job. Something to came back to later when you have another to compare with.

Mate , My old Hino FS was exactly the same,had to lever it up the first bit . Maybe wear in the cab mounts ??? . We have a Volvo F7 {handpump only } ,it goes straight up without any problems .

Thanks ianoz. Can you please answer me a question, when you turn the lever to the up position and start to pump, does the cab jump up a bit as soon as the hooks retract?
Thanks,

Thanks. That'll be the hooks being pressurised until they let go of the cab and up she goes. Something very definitely wrong here then. Have to get the Volvo bloke out to see if he can spot what is wrong.
