Well the GQ went up on the hoist today and the gearbox came out.

The engine was pressure tested and the oil dripped out of the rear seal.

This is the third seal replacement in 12 months. It turns out that all other seals were aftermarket ones. This time we have fitted a genuine Nissan seal. This seal is quite different to the aftermarket seals.

There is no scouring or no groove on the crankshaft end and after consultation with a Nissan Engineer we were advised that fitting a speedi-sleeve may be counter productive.

So the GQ will be on the road tomorrow again and hopefully our leak troubles will be over

BTW the crankshaft was also tested for loose play but there was none.

The workshop is picking up the tab for this work. The seal alone cost $50 trade.

Willem,

I told you to put wing nuts on the gear box. It save a lot of time when the box is in and out as often as a 3lt Nissan blows up :-))

The mechanic took the box out with his eyes closed.

Good work Willem, and do hope that is the end of that leak. Nothing more anoying than a crankshaft leak, front or rear.
Did you check the flywheel runout, I recall you installed a new flywheel so I assume you are now within tolerance limits?
Happy outbacking

Willem,

Always ALWAYS make sure they use genuine parts specially seals.

You will find that the difference in price is not that big anyway.

I am sure that unless they stuff it up on assembly it will be OK.

They also have to make sure they lubricate the seal with good quality grease on assembly otherwise the seal lip which is very tight and soft burns on start up and then leaks again a few months later.

I'm glad that you added the last line as I was thinking "well that's another few thousand k that he won't be able to afford now :)))
My mech will only fit genuine ($$) stuff. I got my knuckles rapped for having a non genuine oil filter in the engine last time. It was easier to raid the spares box than do a 50K round trip to buy a filter. But I was going to change it after around 1000k anyway, as I dont trust non genuine.

Hi Willem
Good luck with the new seal.
My question is why they thought the speedi sleeve was counter productive?
I have used them for years and found them to be very good but one needs to lube the seal before installation as some one has already mentioned that a dry seal lip can burn on start up

When I bought my campervan it had a leak from the transfer case rear seal. The mechanic had one look and said it looked like it had had a rebuld kit put through it which use non genuine seals. 1 10 dollar genuine seal later plus labour it never leaked again
