Engine Rebuild.

Post by **wanderinstar** » Sun Jul 20, 2008 11:23 am

I am rebuilding a 1098 and have bought a locking washer kit from ESM. There is a dished washer in it that I presume is the oil thrower for going on the front of the crank. Question is, does it go on after the timing gear and does the dish face into the engine or away from it?
Also with thrust washers in how much movement should there be?

The dished washer is actually the lock washer for the crankshaft pulley bolt. No, I don't know how it's supposed to work either...

Hopefully you still have the thrower from when you dismantled the engine. It's a flat plate with a slight indentation in the middle. You put it on after the sprocket with the face that has an 'F' stamped on it to the front.

No I can't understand how it works as a lockwasher. Must admit I thought they had forgot to put crank nut lockwasher in.
So next question is if this dished washer is crank nut lockwasher, as Alex says. how does it lock onto crank itself and why is it dished?

No idea, but it's the only washer in the duplex timing chain kit that is the correct size for the bolt. The thrower has a larger hole and a keyway slot. I think if you do it up tight enough it's not going to come undone but if you're worried you could use some threadlock.

Well just been up to garage now to have a closer look. The front of the crank pulley has two indentations that look like they are for knocking part of washer into and then when nut is done up the outer edge can be knocked up over that. Still cant see why it is dished though.

Could be. I didn't notice the pulley indentations but I did use some threadlock and do the bolt up very tight. I suppose the dish shape makes it easier to get a chisel under to bend it over.

Hmm, possibly.

i bought one years ago, ended up using the original

it pays to bend it up slightly before putting on, well that goes for any locking tab

|Yes - two sides should be bent 'into' the pulley indentations - and one other side levered up to sit snugly against the side of the starter dog. Threadlock is a really good idea - clean/degrease the threads (inside and out) before assembly.
