Hello everyone, just noticed a little squeak when starting up the Rover this morning, narrowed it down to the idler pulley on top closer to drivers side. Is there a replacement bearing for this or do you just replace the pulley as a unit? If there's a replacement bearing, what is the part number and where do I get it? If I must replace the idler pulley unit at once, where do I go to get one? Best price? Where from? I have found them but pretty steep for a stupid idler pulley!! ($85.95) I'll pay it if I have to, just hoping someone out there knows of a bearing or cheaper replacement part. Thank you guys very much, lately I seem to have a lot of stupid, picky little problems! Getting through it though! Thank God I do all my own work, or I'd be broke!!

 

You can find bearings for the 3 pulleys so if you want to save money go that route but do all 3. Rover has had issues with those 2 idler pulleys and the tensioner, the have been a few TSB's from Rover on replacing them, so inspect the pulley well before rebuilding.

 

Tensionner: #6203
small idler: #6203
Large idler: #6304
All with double seals

 

Thanks Frankieoboy.

Anything special we need to know do to swap them out?

Thanks again. RS

 

Snap ring pliers, a socket to push the bearing out, and a bench vise, was what it took to replace my idler bearing.

 

Thank you everyone, that's exactly what I wanted to know. Thank you for the part #'s Frankieoboy, lordmorpheus for the tools needed info. and to Disco Mike for the info. on the 3 bearings. I probably would have just done the large idler and not the tensioner and small idler, I will definitely do all three and save myself the future trouble. Actually, I'm not even so sure the others are any good either, I can hear a distinct squeak coming from the large idler but, the others may be ready to go too.

I think I may even have some or all of the bearings already but if I need any of them where is the best place to go? Local auto parts store? Hardware store? Online?

 

Does anyone have a good source on high quality high speed bearings?

 

Most any auto parts store should have the bearings as they are fairly common. You are going to have to give them the part numbers, because there is no application. If the counter guy says the number is no good, look him in the eye, and tell him to get his interchange catalog. At least in the Federal Mogul line of bearings, the last 3 numbers are the base number, with either a prefix of suffix for specifics.
#6203 would be a BCA/Federal Mogul 203SS (stainless steel), 203FF (full face), and I forget the other several types. I have probably spent at least 24 solid hours looking through the bearing catalogs from all of my years in the parts stores.

 

Thanks, I've added these to my interchange list for the DII.
Have you used these yourself?

 

I have not used them yet but it should come up in the priority list. I prefer the SKF brand. To get two-sided rubber seals you need to add the suffix "2RS" to the 4 digit numbers.
