Starting problems. RH 160 and RB 145. When starting the dashboard lights stay on but no solenoid sound at back.
This could be several faults.
The safety solenoid fitted on the left wall of the electronics box can be faulty or there could be a fault in the alternator or the solenoid under the dashboard is faulty.
Disconnect the plug from safety solenoid connect multimeter black white stripe positive, black earth.
When you turn the key it should show current.
It turned out to be a fault in the safety solenoid. The circuit board showed
signs of severe overheating.
When it is a fault in the safety circuit just cutting the white red stripe wire
will fix this.
This means you can engage the starter motor while the motor is running.
When the safety solenoid is faulty it might be possible to buy a replacement
from Hino. It is the same one as the one fitted in the RB145. Any serial
number very close to the one you have will do as they fitted solenoids
which look the same on the outside with slightly different numbers.
I fitted a standard solenoid which works as well without the safety features.
The RB 145 has the same solenoid.

Springs RH 145 Lawrie Little had a bit of a concern with the front springs on his RH. 145
I have been to Carrolls Suspension Solutions 10 Industrial Ave Wacol Qld Ph: 3723 9504 and saw Jim Armstrong.
He recommended putting an extra leaf in the front springs to give more support to the existing springs.
He had had this done and it makes quite a difference to the ride and the bus no longer dips into corners and feels more stable overall.
More on RH145 swaying problems.
Stan Screwko of Springs and Blacksmithing in Cairns. He fixes the problem by adding one leaf to each spring and heavy duty shock absorbers. Stan can be contacted on 07 40512073. 1 Newell Str. Cairns. N.Q

A lot of parts are the same as Hino FD3H or FD3W trucks.
More RH 145 swaying.
Mal and Narelle Brand had trouble with the bus swaying. They replaced the front springs with 5 leaves. Mal believes that they are Mitsubishi Canter ones and that made a big improvement to the sway -
However, it was still not really good, so had the rear done as well with 7 leaves. That improved it about 20% more. It sways a little when it hit a depression, but does not continue to sway like before.
That is understandable as there has been a fair bit of weight added up high. I am yet to give it a really good trial run on some "woopy" roads. The ride is still good. Cost around $2000
Losing air pressure RH 160 I lost air pressure within a few hours. In my case the solution was to overhaul the safety valve. It is situated just above the drain valve on the air tank closest to the left rear wheel. It comes apart easily and a small rubber washer did not seal properly. I made a new one. Because it is a safety valve it has to be opening up at 7.5 Kg/CM This should be your normal operating cut off point. When assembled turn the adjusting screw outward till it just starts to leak. Tighten locknut. Instead of a few hours now it takes a few weeks to go down.
Fans not operating.
I had this problem. Disconnected every joint I could find and squirted some CRC in it. This solved the problem. The manual says to check the fuses but could not find them. Now I know. In my case they were OK. They sit in the electronics box and when overloaded disconnect.
All you have to do push a pin through the hole and it will make contact again. The problem is that the fans are controlled by a computer. If the intercooler fan does not work the other fans won't operate. The computer is located at the top of the electronics box.

Fuel cut off problems.
A few people contacted me with the problem that the motor would keep on running after the ignition was cut.
Most likely the fuel cut off solenoid not operating.
The solenoid on the 160 is on the right hand side of the motor inside a metal box which is fixed to the wall.
Accessible through the right rear door at the top.
For 145 owners follow the cable from the fuel cut off lever.
Turn the ignition key and have someone check if the lever moves smoothly. If it does it might not travel far enough.
There is an adjustment near the cut off lever.
If nothing moves the problem could be in the three pin connector. Check that the blue cable with white stripe has power.
If it does unscrew the side of the box and remove and test the solenoid.
Front fans faulty.
The front fans are two 12 volt units wired in series. To remove them is possible but awkward. The two on the top are M10s and the ones at the bottom are M12 bolt.
After I removed them both, connected it to a 12V barrery and they did not go.
To open them up bend the tabs on one end and remove end. In my case there was enough of the brushes left but they were stuck. Reposition the spring holder and remove brush. File or sand till it moves freely. Assemble.
Here the brushes stuck in place This is the way it supposed to be
Now I have the bus for 11 years more air leaks developed.
When you squirt soapy water here are a few places where this does not work. Remove the rubber booth from air governor valve and spray. Put a balloon around the purge valve at the bottom of the air dryer. Mine fills up a balloon in around 10 minutes. Not fixed yet.

To get to the purge valve remove air dryer. From base remove circlip and valve assembly. You do not have to open the dryer.

RH 160 Engine mounts.
Both my engine mounts were half broken. I had difficulties finding replacements as you do with the 160. Mounts which looked the same on the internet picture would have cost me $175 each with no guarantee that they would be the same. I found mounts for the Toyota 2H motor which did not looked the same but fitted perfectly for $60 for the pair.
