Not really a river crossing, and seemed a lot deeper at the time however here's some good times in the Blue Mountains :-) Compared to the others it looks like I wasn't trying....  |

Not many rivers that run here in Queensland  but i did drown my MU. Lucky it was the petrol one just puled the spark plugs out so i could get all the water out of the cylinders   |

Some times your lucky sometimes you aint. The engine speed and vehical speed would have an effect on the damage done because both of these effect how hard the piston hits the water in the cylinder which is like running into a brick wall. vehicles have died permanantly at idle speed though so dont push your luck more than you have to. Second hand 4jb1 engines are getting $1500 on trademe.
Ive seen 6 vehicle drownings 3 didnt survive and one of these was petrol.

I hit the water at about 4000-5000 rpm in low second I did not think it was that deep 2.6 petrol motors are cheap $600 over here The hardest part of getting it going was taking the dizzy cap of and putting it back on |

some times you are lucky Petrol engines can be more forgiveing because the electrics normaly stop before the lungfull of water but not always.

Hi pig75 Still a great effort though?, least you gave it a red hot go machine against mother nature (you lost) unchecked depth in murky water is hard to do at the best of times? It's like a kinder surprise!!. Even i dont like err-ing on the side of caution but go in with guns blazing & sometimes paying the price he-he-he.. Nice $600 pic if thats what it costed for a new motor. btw did the cab fill with water to? cheers muvit  |

But all I needed to do was pull the plugs and dry the dizzy cap  and wring out the air filter. The same motor is still going strong ;D Got some water in the cab  |

just got back from the river after getting stuck in the middle of a crossing this is the first time ive been to the river with the mtrs and i must say im not to thrilled with them i think that our old buckshots worked better in this situation, any way heres the pic ;D  i was just about through but got deep just before the bank to climb out after been stuck for a while and the cab filling up with water i let some air out of the tyers and gave it a bit more death and wolla it came out. ;D so now im off to take the locking hub to see if it got flooded too does anyone have any tips on removing the wheel bearing seal with out damaging it, or a part number and place to by new ones i take it there cheap, think im gana have to regrease them  |

The seal should come off the stub axle fairly safely and easily as it stays inside the hub. Ive always driven it out at the same time as the bearing ring with no damage but if you are only repacking the grease you wont want to dislodge this.

ok pulled the locking hubs off the other day, they had puddles in them:( so i stripped them and reassembled them, also had a look at the bearings but they were mint still heaps of grease and no water, now my question is, is it normal after been stuck in a river for 30 odd mins for the hubs to let water through. im guessing so but just wanted to see what others think?
theyre all greesed up and ready to go now, used some really good expensive greese i got from work haha

3 possibilities
1 if hubs were very hot due to lots of heavy braking they will cool rapidly sucking water in Only answer to this one is if you have been braking lots let them cool before wading (not always possible)
2 the gaskets in the free wheel hub (2 paper gaskets and a seal around the operating control) are faulty. A lot of people through the gaskets away and use good flexible sealant instead.
3 At the back of the stub axle where the half shaft goes though there is a seal and needle bearing.Also there is a thrust washer as well. These wear out quite frequently. Seal is isuzu only as is the thrust washer bearing much the same price as after market. To get at them means removing the stub axle completly and driving them out the back

ok, i had sealed them up with a rtv sealant before so its not that.
so you think if it wasnt hot then it should have been dry inside still, even tho it was submerged for quite some time in a small current?
i was thinking of maybe the seal were the nob to lock the hubs is letting it through as its just a o ring that dosnt seem to be very tight, would it be possible to get a slightly fatter o ring
other wise im gana have to pull off that dam hub again! do you have part numbers? i take it they come from holden?

What can also happen is the hubs are sealed good with RTV, the back seal is good but the little needle roller is duff and allows the shaft to slop and deflect the otherwise good seal... and then it will leak. I would look at that angle before the hubs o-ring sealing.... A good test is climb underneath and grab the shaft near the outer CV boot. Wriggle it up and down. If there is much play the little needle roller bearing is probably duff. Then try wriggling the shaft in and out. If there is much the end float (the amount of play in shaft) is not properly set and the inner back of hub seal (yes there are two seals we are talking about) will not seal. Set the end float with shims behind the CV shaft C clip... but not normally necessary. Your local holden dealer should pull out a nice thick parts book with diagrams to help you understand, and for him to get part numbers from... ask for a photo copy of the page...
I have a scan of the required page somewhere.....
Don't worry, soon you will be able to do the whole thing in an hour flat like some of us on here who have been there a couple times :-)

on both sides there is 1-2mm play each way you discribed, is this normal? i take it the only way to check the seal it by pulling the hole thing apart.
im getting there, down to about 1.5 hours a side just a pain in the arse as ive just re greased both sides.

and wring out the air filter. The same motor is still going strong ;D
