What does this bit do.

roycruse · 17 March 2006, 13:35

Whilst putting my new stainless prop on I got up close and personal with the prop washer that goes between the castle nut and the prop.

It seems to have a raised section which would appear to have no purpose what so ever. (see red circle on attached picture).

I hate not knowing the purpose of things so if anyone knows what this bit does I would love to know.

I dont know, but would guess at balance , same as a car wheel

roycruse · 17 March 2006, 14:14

That had crossed my mind - but if that's the case how the feck do you know which way it should be - i have no way of knowing if my prop needs balancing and even if it did how the hell would i know which direction to point it in to have the desired effect...

It looks like a key to me.

Was it the other way round with the stock prop, and locate into a keyway?

It's a trick washer...it appears to be working.

No it was like that on the old prop too - im assuming everyones Suzuki's have a washer with this same raised bit - somebody must know what its purpose is !!!

Mine doesn't......

Jimbob · 17 March 2006, 15:28

it still might be for balance, if you think about it its exactly the same principle as a car wheel. so maybe it should be in a certain position..........i may be talking bollocks as i often do.

Its a DP Lug

roycruse · 17 March 2006, 15:38

balance is the logical answer as i cant see what else it could be for - but how do you know what position to face it in then ???

at the moment its in a random position and could very well be making any imbalance worse...

Edit :: Just checked the manual the component is referred to in the manual as a "spacer" but there is no mention of needing to align it with anything or the raised section having to key to anything...

I'm still frustrated - no conclusive answers yet

Now you've brought it to peoples attention " Eveyone will Want one"

Jimbob · 17 March 2006, 16:41

Maybe for your old prop it was for balance, as you say there is no other logical reason to have an offset peice of metal

On the new prop it may not needed it as it may be balanced, it still needs a wash

Give it a spin, see if she wiggles, the engine that is

roycruse · 17 March 2006, 17:32

A wash

cheeky bugger - its a brand new prop and that there be fresh greese...

roycruse · 17 March 2006, 17:36

The old prop was just as symmetrical etc as the new one - if it needed that raised piece i would have had the same issue as i have now - which way to orientate it.

I am pretty sure that its too close to the centre to have to much of an effect on balance anyway.

I have just been out and spun the thing up in my driveway looking for any vibration - but i cant feel any up to about 3k RPM - didn't fancy running it dry at any higher revs than that.

I guess it will remain one of the mysteries of the universe...

Jimbob · 17 March 2006, 17:40

seems that way,somebody must know, just knowing who, good luck an interesting post

jyasaki · 17 March 2006, 18:53

My guess would be that it is a block for a locking star type washer, which is apparently not used anymore. Just a guess, though.

There's no way that little bit of metal so close to the centre is going to noticeably shake your engine.

Get out the fekin angle grinder and then you'll be rid of the worry....
