Waterpump change

[selly]

I had a leak from the waterpump on my 2001 172, I had a look underneath and thought I would only have to remove the aux belt when I removed the 18mm bolt off the bottom pully I noticed the crank/cambelt pully had no woodruff key holding it on to the crank. I continued and replaced the pump, refitted the pully's and belt. I came to start it and it doesn't run. Sounds like the timeing is out. Can any one tell me if I can time it back up on the bottom pully?
Any advice would be appreciated.​

DONT try to start it. the timing is fully floating and you need the full set of locking tools. Where are you?

Whupz.

Where are you?

Up a creek without a paddle would be my guess !

well I'm trying to be positive and imagine there's no bent valves. I can't see it though. I'm gonna take 6 in the sweepstake

Bit far for me to nip over and have a look really. I think you're going to have to get it recovered somewhere to a specialist and have it checked out. Personally I'd re time it, then do a compression test, and stick the bore scope in to have a look

Oh dear, lets hope no damage has been done.

wot do you you mean when you say the timeing is fully floating? is ther eny timeing marks on the bottem pully??

 

[sideways danny]

no marks, no woodruff keys. 100% cannot be done without the correct locking tools

 

[rosskerr]

not someting to be fucked about with definatly be recovered imo

 

[Fred@BTM]

how did you refit the pulley? just tighten the bolt back up?

that'll be fucked

Not entirely true Danny, there is a timing mark on the crank. There is a notch for a woodruff key and when 1/4 are at TDC it lines up with a casting mark. To be fair though its more of a "Confirmation you've got the crank pin inserted correctly" mark than an actual timing mark.

It does 100% need the use of a crank lock pin and the camshaft setting bar to get the timing back to zero though.

I'll travel to York for you but It won't be until Wednesday i'm afraid.
