Pulley Noise -with pics - help

[occasionaluse]

Finally found where the strange scraping noice is coming from - it is the pulley at the top nearside of engine (where PAS pump would be). Sounds like the bearings - i tried to get a replacement but to no avail - here are the pics of the part -









I think this is a part made by TVR - the only number i can find is on the bearing ring - RSR 6305 - so maybe i can buy that and hope to get it out of the housing.

My other thought is to run a shorter v-belt and miss out that pulley altogether - i.e. around the crank - water pump - alternator - tensioner - (i think there should be enough friction to turn the water pump - standard belt is 1850 i think - and i can get a 1288 belt which i believe is perfect if i miss out the pulley in question).

Advice appreciated....

6305 is a standard 25mm bore (i think) "popular metric" bearing. It will be off the shelf at any bearing distributor for a couple of quid. Get a 2RS version with rubber seals as this will keep the dust etc out.

Unless it is installed with a circlip, it will push out with a bit of care.

edited to add: the centre punch marks on the front of the housing have been made to stop the bearing falling out. Push it through these and use bearing lock when you put the new one in.

thanks for that - i had a look for the 6305 but there were lots of versions with letters following them - so i will take your advice and get the one you suggest.

If you get stuck,try that number as a motorcycle wheel bearing(poss rear) it will have seals and grease packed standard(just what you need)

THanks for the help - i think i will try to go in and get one from a motorcycle spares shop (internet ordering is great but i am never in when they deliver). So i guess i find something to get the old bearing out and when i put the new one in "bearing lock" was mentioned - i have not heard of this before - can anyone give me a heads up?

RSR just refers to 1 rubber seal. Should be dead easy to find from local supplier or online..

It's a Range Rover part. pretty straightforward to get hold off from a TVR or Rover V8 parts specialist.

I went to a Land Rover dealer on Saturday - and spent one hour going through all the diagrams of every part they have. The mounting bracket is Range Rover for a power steering pump, but there was nothing at all that was just a bearing in a carrier - I took the part with me - even showed them the number o n the bearing - but they came up with nothing. I get a bearing and hope i can get the old on out and the new one in. I will keep you posted.

Thanks for all your help - once again amazed with the info on here.

"bearing lock"

Its a special adhesive used to retain bearings in their housings - dont worry, the bearing can still be removed in the future if you need to.

The place where you buy the bearing will also sell you a bottle of it.

I did say a TVR or Rover V8 specialist as the bit you want is normally supplied with the engine when the engine is shipped from the engine plant. Land Rover replace it with a PAS pump.
John Eales at JE Developments would also be another guy to contact as he as a barn full of such spares.

Quick Update, I have the bearing and now need to remove the old one, pu thte new on in. However just in case anyone else has a similar problem i used a 1288 7 groove belt and missed out the offending pulley altogether - i was worried that the water pump might not have enough friction but it works an absolute treat - no slippage at all. So now i do not have to rush to get the job done. Just thought it might be useful to know.
