Tensioner Pulley rebuild?

The bearings on my tensioner pulleys might be due for renewal. It appears that they are press fit into the arm and the pulley is pressed onto the bearing. has anyone evr tried to fix these things? New ones are about $200 compared to 70 for the bearing. 4.2 serp belt loob

if it is the same as the tdi unit (it probably is) I got my bearing for $12 at a local supply. was able to worry the reatining ring out with a small screwdriver and knock the bearing out and back in with a socket. piece o' cake.

Agreed you should be able to find a bearing cheap locally. Take it to NAPA once you have it out and they can match it up to something in stock.

Hi Bill,

If the 4.2 serp is similar to the 3.9 and the later 4.0, the pulley / wheel should slide off of the shaft.

There is at least one circlip (I can't rememver if they're on both sides or not) holding the little bearing in the pulley.

On my '94 Disco, this was a normal everyday circlip with holes in it. Get the pliers, pop it out replace the bearing unit and that's it.

On the '97 D90, the circlip had no holes!? Judicious use of a small drill bit and repeat the above instructions...zip-a-dee-doo-dah....quiet pulley.

I took the bearing to the local NAPA and found replacements for something like $8. Yes, I have extras on the shelf.

Cheers,

KAA

Dayco is a decent brand and is OEM for the belts on my rovers. Not sure if it is any good for tensioners though.

I'd fix the o.e. pulley and toss an extra bearing in the cubby, that way you know how to do it if you really need to.

Literally might take 10 minutes longer that remove and replace with a new one.

Blast. I read this as indicating 4.2 w/ a serpentine set up.

Yes well 4.2 is a mashup of v belts and one seep. Easy to mistake

As in my sig, 93 lawib. Not 95. If I have confused anyone, my apologies. Pulley in question is the v belt tensioner. There are two on this engine. The other flat ribbed belt is tensioned with an adjustable arm on the alternator.

Out of curiosity, how did you know that it was time to replace the bearings? I'm getting an occasional squealing from that area and I suspected the pulleys but wasn't sure.

replace bearing

This is a real easy job. Bearing at NAPA is $9.00 and it should take 30 min start to finish. No special tools needed, snap ring pliers, hammer and socket to drive out the bearing. Bench vise to fit it in. Easy DYI project. Save your $200.

Do you have a part number for the bearing by chance?

Bearing is a 6203 on Tdi engine, i guess it's the same on v8.

Just think it's time. these are OE and seem OK, I'd like to do it for peace of mind.

Ur, not exactly. Maybe if you are referring to the Tdi engine. The one on the RRC has no snap ring or any other obvious means of taking it apart:

Bill--the bearing you are referring too is a more specialized bearing as it has an integral shaft/strange configuration. I believe there was a post on this board that referenced this bearing in particular if you can find it. I know a couple people have made there own by turning their own adapter and using a timkien bearing--I'll see if I can find it, but it may take some searching... I may have saved it in one of my archieves, but those are now really big and poorly labeled on my machine...
