big problem?
Turbo Mini Forums

no quite sure if i have hit a big problem

went down the garage today to do a bit of work on the mini, i started it up and it made a strange noise like if the water pump bearing had gone so i turned it off.

looked around and seen that there was oil coming from the bottom pulley!!!!! i think the pulley has come loose. would any damage have been done???? i hope not

i hope not investigate further pronto!
my monies on the altinaler is siezed check that out also

Sounds like the pulley bolt has come loose. If its only just started then you might be lucky.

It happend to me, and wrecked my key,pulley and threads on the bolt.

alternator is not seized and is charging fine

Investigate,

if the pulley is coming loose you run the risk of shearing the key that holds the timing gear on, in which case you could trash the engine.

Pull it all of and check the the key (and replace if it looks iffy) I''ll be suprised if the source of the noise and leak dosent become obvious as you pull stuff off.

would it have caused any damage if it was running for less than a minute.?

not unless it stopped

good good hope its going to be ok
when i get time ill strip it down and sort it

i had one come loose once and it cracked the pully where the seal sits, so id check that when you get there

Same happend to mine, the pulley split on the keyway. I must of done a fair few miles on mine though before I realised.

had a look at the pully today, stripped the rad etc off and got to the pully bolt.
got my big socket and bar but i cant undo or tighten it up?
now im home i thought, do u use something on the flywheel to stop the pully from moving???

Take the starter motor out then you can insert an old bearing shell in the flywheel to lock it into place.

Dazed and Confused....

Just stick a screwdriver in the teeth of the fly, nut should be torqued to about 75ft lbs iirc.

nice one cheers

impact gun helps a lot too !

Bought myself an electric one last year, best 60 euros I ever spend on electric tools !

Rusty by nature

right going to have a look at this this weekend, will i need a new bottom pulley or should it just tighten up?

check it over for cracks if all looks well bolt it up

been a while, i cant move in my garage as i have avw camper in there aswell.
i just tightened the nut today but its still makes a noise and oil still comes out from behind the pully

You need to replace the oil seal then

will the seal just fit without removeing anything other than the pully

no, you need to remove the timing case cover to get at it as its knocked in from the back.

This will give a good chance to have a look to see if the oil thrower ring has been fittd the correct way round and whether the bulge has ben knocked out in the cover if you have fitted a duplex chain. These two issues will give a similar noise to what you describe.

when you fit the timing case cover back on the engine, before you nip the bolts down, fit the crank pulley to centralise the seal, then gently nip the bolts down each a little at a time. Also make sure that you use the correct length screws with washers so that they themselves do not push the front plate away from the block, thus creating a leak that appears incurable, and phantom like.

its been a while!!! lol

the engine is out and i have removed the timing chain cover and the seal was knackered

the lock key looks fine but will change this

anything else i can do to ensure it dont happen again?
will this stop the knocking noise?

thanks

Depends where the knocking has come from. You state that the oil light came on so that suggests ur bottom end bearings/ oil pump are shot...

As for the pulley not coming loose, torque it up properly, use locktite and knock the lock tabs over
