Winch Pulleys

[101RRS]

I was working on putting my winch cable back on and noticed that the chassis pulleys have seized. As usual what looked like a straight forward job to pull them out and regrease etc is not straight forward.

Basically I cannot get the pulley off the bolt and I cannot pull the whole mounting off to get a good go at it on the bench because Landrover in their wisdom decided to put the exhaust manifolds in the way.

So, can someone tell me if the pulleys turn on the bolt or is the pulley threaded onto the bolt and the pulley and bolt turn as one unit - this is how it is turning at the moment.

Thanks

OK - so how am I going to get the pulley off the bolt - either rusted or screwed on when I cannot bash it, cut it, or oil it in place - and I cannot remove it unless I unbolt the engine from its mounts and move it sideways so that I can pull the entire pulley mounting out.

Garry .
I think all the pulleys are the same and have a ball race in the middle of them.
Mine if not used for a while and the vehicle being used in wet weather and mud tend to seize a bit.
I either work them by hand a little bit until they spin again or soak the top middle of the pulley where the bearing is with WD40.
Doesn'T the pulley near the exhaust manifold unbolt from the chassis ? with two bolts.

Note the two chassis mounting bolts on the left pulley and how the top of the bearing can be filled with WD40 or light oil...........it is also why they seize as they fill with water too.

The chassis pulleys should be the same as the fairhead pulleys with internal bearing and if no paint and rust is around should pull off the bolt , just like the fairhead.
It is all new terriory for me as I have never had to remove them , other than the fairhead pulleys and I suspect the bearing themselves may be retained by cir clips.

I have unbolted them but they will not come out because the exhaust manifold stops them .

Mine is so seized that the bolt will not move with the pulley locked and a rattle gun on the bolt - or even a 2' breaker bar with a 2 foot pipe extension.

Maybe some time for some heat or unbolt the engine mounts.

Garry,

I replaced my bearings while the engine was out. It has a standard sealed ball bearing with 20mm ID and a shouldered collet pushed in from either side. The M16 bolt sits inside the collet.
It is the same setup as the twp pulleys on the swivel assembly. I have to get new bearings for these so I pulled the collet out this arvo. Hope this helps

I ground the head off the bolt and as expected the pulley mount on the outside of the chassis fell away and with that removed, the inner mounting could clear the exhaust and come out.

A surprise was that my pulley does not have a bearing - the pulley just turns on the bolt and it had rusted on through lack of use. I will get a new bolt, clean up the hole in the pulley and lubricate with never seize grease and re-instal.

The second pulley came straight out and it too did not have a bearing but turns on the bolt.

Thanks to everyone for your help.

I wonder if you should have the pulley machined out and have a synthetic bearing inserted, or drill a grease-way and put a grease nipple on the pulleys?

That way you can lubricate the metal on metal surface without having to disassemble the carrier, or better still have the synthetic bearing that doesn't require lubricant. Although I prefer having both the synthetic bearing and grease nipples as well.

I did think the same but when it is not seized it is a two second job to take out the pulleys. So I will just put it on the maintenance schedule. It would different if it were something that was being used all the time or at high speed but it only turns at low rpm as the cable runs on it.

However now that I know how it all goes together, if it does play up in future I will make the hole large enough to take a small sealed for life bearing.

Cheers
