Thread: Isuzu MSA Gearbox to LT230

85, see previous entries in this thread for link to my build. I elected to buy a kit.

My photos will no doubt give competent machinists some idea of machining required. If that's you then knock one up and I'm sure others will be knocking on your door...but I suspect you may have to make it real cheap cost wise, but with high quality

Anyone had any thoughts on how to keep water out of the gearbox? In particular to the clutch fork boot.

What are you worried about? Clutch slipping when wet?

Lack of drain. Filling up whilst doing river crossings. Wear and tear from water ingress. Thats it

The bellhousing isn't anywhere near water-tight, so it self-drains of water and oil quite well. The only place water can get into the gearbox itself is the poppet breather on the top cover. I replaced mine with a barb fitting to breather tube.

This of course leaves the clutch plate/diaphragm and throw-out bearing susceptible to water. I suspect you'd have to get them wet often to cause a problem. The clutch plate/diaphragm will throw water out just with engine rpm.

Sorry re read my post, meant the clutch area not the gearbox

Vern Water in the bell housing wont be a problem The only time it may be is if you do a deep water crossing then not use it for a couple of days.Organic clutch plates tend to grow onto the flywheelForky stick to hold clutch down overnight does the trick

More thinking of thrust race bearing and spigot. I'm sure bugger all will get in, was just curious
