Thread: Gav's 101.

You have the same size tank in the same position as mine.
You may as well place the horn in the same spot.
Placing the horn under the air tank keeps the hose short and you just feed the horn air solenoid straight from the normal horn which is not far away as well keeps things simple.
You will find it is a good spot for the long length of the horn too.

As you may be aware I now feel inadequate so I have now fitted a steam whistle to my 101 , but operates on air.
I feel having a whistle will still give me a edge in the show off stakes.

I wonder where I got the idea for the tank location...

I will be mounting the horn under the passenger wheel arch though - I did look at mounting it under the tank, but I didn't like that you could see it from the front of the vehicle. Air line will only be a few feet long, and the solenoid is mounted on the horn, so it has air pressure right to it so there should be no lag hopefully.

Here's a pic of all the air stuff mounted - all done except for a couple of hose clamps on the main line from the tank to the manifold and a few zip ties to tidy it up. The manifold has 4 outlets on the top, from the back they are the horn line, pressure switch (120 off, 90 on), a 145PSI relief valve that flows 10CFM, then the gauge at the front. There is an outlet at the back which is currently plugged that I can use if I ever put a front air locker in.

The braided line is from the compressor - I was advised by the air guy that the standard line wouldn't cope long term with the temp of the air coming out the compressor - it is only rated to 80 degrees - the braided is rated to 180. The main air fitting worked out perfectly with a 45 degree elbow in it. Just need to get a rubber boot for that so it doesn't get full of muck and insects.

I had to use high temp hose.
I also keep engine revs under 2000rpm when using mine.
Some pics for you.

My installation doesn't look pretty anymore as it has been in use now for more than 6 years.
Gav when are you fitting the front vents????????

Hmmm, started the mechanical installation but have given up tonight and had a G&T instead. Looks like there is plenty of room for the big arse York compressor to go in now the alternator is gone - I'll be sticking a 65 amp Bosch unit in on the other side, but while removing the gear stick bracket - the big ally one, I find that it appears LR in their infinite wisdom installed this bracket BEFORE fitting the front cover on the engine....

One bolt fouls the back of the water pump - not a huge issue, I have undone it far enough that I can cut it with a hacksaw blade and get it out, but that was enough for me to pull the pin tonight...

A shorter bolt replaces it on the compressor bracket which can be got in and out easily.

Hopefully it will be making some nice truck horn noises by this time tomorrow....

On my 'to do' list - I was going to do them this week, but I got carried away with the air instead. I'll drop in at my local marine shop in my travels and find the vents - installing them is the easy bit.

What's the risk of running the engine past 2000RPM with a setup like this?

I had to pull this of the disco engine that mine came with, and refit it to Bojans borrowed 3.9... I know the bolt you are talking about.. Seem to remember with the Viscous Fan removed (LH thread and strike spanner with hammer to undo before removing pulleys)and the pulleys removed you can refit it easily using a slightly shorter bolt.
