I have a 86 Samurai 1.3, thats leaking oil at the front, so I'm going to replace the crank seal also the timing belt and tensioner, should I replace the camshaft seal , water pump?? Anything else i'm missing that should be replaced while i'm in there? I've never done it on a Samurai engine. I have several ASE certs. so doing it is not a problem, just want to have everything on hand when I start.  Thanks

may as well do WP; I think it shares hardware w/the tensioner anyways...

The tensioner bolts onto the pump.

It appears to be "conventional wisdom" to replace the water pump, the timing belt and the tensioner at the same time - and you'll often see advice to this effect, accompanied by such gems of wisdom, as you might as well do it whilst you're in there.

Personally - I've never understood why - given the fact that it's my time (to replace the parts) & my money (to purchase the parts), I would rather consider the pump as one entity, and the belt & tensioner, as another - and replace the one that is bad - I don't exactly see the point in replacing functional parts.

The last time I changed a belt, I didn't bother to touch the pump, and a year and a half later, it was still going strong.  I did replace the pump at that point, along with the belt & tensioner - but that was done as a part of a "full rebuild" - and all of them could have been reused, had I so chosen.

Just my $0.02

more of murphys law. once your done with installation of the belt, the waterpump would go. and everything you just installed will have to be ripped back off.

One of the key items that you need to be aware of is the crank bolt.

It is a very common occurance in Samurais (and TracKicks, too!) that the person working on the front end of the engine (usually changing the timing belt...)  will remove the crank bolt and not:

1) Replace it just to be safe

2) Re-install it without properly applying appropriate threadlock and the factory-specified torque.

The end result from not doing the above is - invariably - a wallowed crankshaft keyway.

I mention this because "assuming" that you would be aware of this situation is a bad thing to do to a fellow Zuker...

I hope that this helps! 

Just to throw my 2 cents in- If the crankshaft has a groove in it from the seal, you can put a speedy sleeve on the crankshaft or the new seal will leak just as bad as the old seal. They are not cheap (about 25-30 bucks) but it will be better than a new leaking seal. If it is the cam seal, I found the new seal made contact in a different spot so I didn't need a sleeve on it. This took care of my leaks on my 86.
Good Luck

I think I'll just replace it all while it's apart. Thanks for the info.

Personally - I've never understood why

Because I hate pulling the front of the engine apart, and a water pump is worth less then my time if I have to pull the stupid thing apart again. 

One thing I do recommend is taking some sandpaper to the tensioner pulley when replacing the timing belt.  Sometimes it will have a bit of rubber on it from the old belt and it will cause the new belt to want to slide off.

Has any one bought one of the kits off of Ebay that has the timing belt, tensioner, seals, water pump ? Just wondering if there any good or just cheap junk.

I found Rock Auto had prices I can live with and not worry about
quality, but if the vendor has a good reputation for those parts
you could try them

Thanks, Wild

Interesting - you're willing to pay for a new pump, but not a new tensioner -

I didn't need one.  On BRD HNTR's 8 valve we had to pull everything apart two months after replacing the timing belt because the water pump went bad.  We noticed that the belt had slid forward and started chewing into the timing belt cover.  Instead of waiting a few days to get a new pulley he decided to just sand it down and see if it worked, and it did.
