marina crankshaft pulley

Post by **picky** » Fri Nov 17, 2006 7:22 pm

i bought a marina crankshaft pulley on ebay, it has a rubber insert that looks knackered, is there anyone that sells just the rubber bit? im fitting it to my 1098 as i assume the rubber acts as a crank damper?

cheers,

i eleive esm sell them, but it may be the whole pulley and not just the rubber damper bit

The rubber is bonded in - if it's really knackered then that's it. However - I have never seen one that's so bad it can't be used - can you put up a picture ? I 'think' the ESM pulley is solid steel - and so won't have any 'damping' effect. It will be a nice strong pulley which won't fall to bits when the rivets work loose!

it is useable, but i think that if the rubber gets any worse over time then the pulley will not run true and will throw the fan belt off... ill put it on and see what happens. cant get the old one off though ...

But the pulley bit should not be rubber mounted - just the outer ring. Is it the bolt (starter dog) that won't come undone - or the pulley that won't move on the crank ?

managed to loosen the nut but cant remove the pulley. last time it took me ages, its difficult to use a lever behind it without squashing the timing cover. ive soaked it in WD40 shud help..

Aye - two tyre levers one each side but the casing is always vulnerable. wd40 is not a release oil. You may need to heat it - and you will be fitting a new crank seal to the timing case anyway - i expect!

ive always found wd40 useful for pulling things apart. only got one tyre lever so i will have to improvise.. annoying that i will probably have to take the radiator out just to get to this thing..

Yes but nowhere near as good as a proper penetrating oil.

Fortunately it's only a 5 minute job to pop the rad out - well worth it for the improved access - and minimising risk of damage to the rad!

got the rad out and fitted the marina pulley, the belt doesnt come off anymore but it gets twisted round somehow but still stays on. I have only started the engine and had a look, have not tried driving it anywhere. How is the belt getting twisted??

Are the pulleys aligned? If they're not, it can cause the belt to come off.

Pulleys must be quite seriously out of line - usually the water pump and crank pulley will be in line ok - just need to adjust the alternator with washers. Just sometimes the water pump may need attacking with a file to move the alternator back slightly.

well thats interesting because this fan belt problem only started after i fitted the alternator (had dynamo before) but the bottom pulley looke really bent anyway so i replaced it. best way of checking they are in line? i was thinking holding a metal ruler along the edge of one of the pulleys or something..

That's just how they say to in the manual

i must be a natural engineer

or maybe ive read it in the manual before

Psst its called a straight edge

ive realized my fan belt is too long... so much for being a natural engineer

looking at the dynamo pulley it is larger than the alternator one. so that explains why the belt fitted ok before replacing the dynamo with the alternator. although the pulleys might not be on exactly the same plane, im going to get a correct length belt first and see if that solves the problem. ESM list several belts, but i assume the standard one for a 1098 will be too long?

825 mm if I remember correctly. And it's too cold and nasty outside for me to go and check!

Yes just ask ESM which is the correct one for your set up.
