ZD30 CRD Belt tensioner pulley.

[10G]

What's the thinking with these pulleys?

Do you replace the entire unit, pulley & mount or just the pulley?

Do you use genuine or after market?

[the evil twin]

IMHO... replace the assy (pulley and tensioner)

I used genuine so don't know if the aftermarket are any good or not.

There's a H U G E difference in price between genuine & aftermarket.

The price for genuine makes lithium batteries look reasonably priced.

Do you need to replace the pulley or is it just the bearing gone. A new bearing is around $20 to buy. The number is (NTN) 87503. Press the old one out with a vice & large socket & press the new one in.

The bearing should measure 40 x 14 mm & have a 17 mm centre.

I find its the bushes in the little spring tensioner that goes in them. as above replace the bearing is easy and cheap.

Thanks guys I'll look into it all.

The bushes flog out and the shockie thingo loses its tension. The genuine bearing in those are double row and a stupid width too, you can't buy the exact same bearing. The aftermarket tensioners use a single row bearing, they work but wont last. Been down this road many times before. The best thing is to buy an OEM tensioner, and an aftermarket as a spare and keep this under the passenger seat.

mudski is spot on use genuine and only after market for a short time. alot of things on the patrol love to be only genuine such as tentioner, belt, fuel filter. ive tried non gen and always end up back to genuine poor man pays twice
better to just buy genuine and you will only cry once.

This fits in with what I'm thinking. It's an annoying small unsophisticated part, but it's job is pretty darn important.

Yeah when I had my Grenade I always had a spare MAF, belt and tensioner under the passenger seat.

I have had and aftermarket set of front belts from SeatSafe https://www.seatsafe.com.au/ for around 10 years and they work perfectly (like any normal seat belt should). I have aimed a number of people in their direction and all are happy. Only problem I had was their data base shows Patrols have belts with pre tensioners. Mine does not - so I called them and just asked for a normal non pre tension belt for a Patrol and it works great. Only difference is between wagons and utes. Search this site for previous threads.

Genuine assembly. Genuine assembly.

3 year ownership of a crd zd30 and I've chewed through 2 of them units.
Yes ,many river crossings and high country dust might have contributed ...

Don't get me wrong - the bearing from WC87503 NTN is devinitly just a one row bearing, according to their homepage and drawings. Dimensions are ID 17 mm, OD 40 mm, total width 14.288 mm.
