NSW manual cam belt tensioner

Camshaft Belt Tensioner (16V, '86-'9 [109 056] - $35.00 : Techtonics Tuning, VW and Audi Performance Tuning and Repair Parts

I'm after one of these with the 10-8mm stud/washer/nut so that I can convert to manual tensioner on my BJX 1.8T 20V. If anyone knows where to source these domestically or has one themselves, please let me know.

thanks

Try Bursons, Dayco makes the timing belt kit for these engines as well and the tensioner looks exactly like the one in the picture.

Really! Man I tried VW but they put me onto a VW vintage supplier. I've tried a few other older VW suppliers around sydney with no luck (was told these engines were never sold in dubs in Australia) , and they may just have them at bursons. jeez.. thanks mate. I'll be down there tomorrow.

are the 1.8 16V engines the 'KR' engines and the ABF is the 2.0? What cars were they in? not good on VW history pre 9N3 Polo I'm afraid.

[Umai Naa!!]

Early or late ABF?

Based on the mention of the 10-8 stud, I'm assuming late.

Apparently, part numbers are as follows:

Tensioner: 051109243A
Stud: N0145931 M10 x M8 x 58mm (discontinued)
Washer: N0122293 8mm x 15mm x 0.5mm (discontinued)
Nut: N01100830 M8 (discontinued)

Probably easier to source a late ABF complete timing belt kit, and take what you need from it.

I'm relying on my memory here. The KR was the 1.8 16V that was in the first Mk2 16V. I'm pretty sure it was never sold in any VW here in Australia. I had one in my imported South African Mk2 16V. It was a very revvy engine with about 138hp but not a lot of torque down low. I replaced it with a 9A which was the US version of the 2.0 16V and was known as the bubble block. If you saw one you would understand why. Due to less aggressive camshaft profiles it only had around the same horsepower as the 1.8 (136hp I think) but a truckload more torque. I believe you could put the KR cams into the 9A head and that gave you the 150hp that the 2.0 litre 16V engines had in the UK and in the later versions in South Africa and also in the 2.0 16V versions of the early Mk3's.

The ABF was a newer version of the 2.0 16V engine and appeared in a very limited run of Passats and also in the Seat Ibiza Cupra
Sport 2.0 16 Valve to give it's full name. It had a longer (taller) block and also had 150hp and also was very torquey. I've had 2 of them.

Umai Naa sorry I should clarify. I was going to change the stud as good practice and incorrectly thought that it was 10mm within the head of my 1.8T 20V BJX. Its in fact an 8mm stud inside and out. The other people who I have seen do this conversion must have all had big port heads and so needed the 10 to 8mm stud

[sambb]

So assuming I can source the tensioner roller (from somewhere other than the states where they want stupid money to post it here), will it just fit straight onto my existing 8mm stud/washer/nut that my BJX already has?
I have a stock timing belt kit ready to go but I have a leaking water pump so I'm fitting a Cat Cams adjustable timing pulley and figured its the right time to convert to manual tensioning while I'm at it.

[Umai Naa!!]

The tensioners look to be in abundance on Ebay out of the UK for around $45 shipped.

[sambb]

will the tensioner be that part number that you mentioned above or different because maybe I actually need the KR and early ABF tensioner? hmmm are ebay brands trustable for this kind of thing??

[Umai Naa!!]

There's only so many bearing manufacturers in the world.

The part number is the same for both, except for the later one having the A suffix.

Any Dayco timing belt kit for mk1 mk2 has manual tensioner KT70. It should fit your engine. You can also check it at the Bursons before you buy it. Easy enough when you have the sample with you. As for stud, I’m sure that can be also sourced locally, if it’s not included in the Dayco kit.

[sambb]

Alright thanks fellas. Really appreciate the help. I'll get down to Bursons today and see what they've got otherwise its ebay.
thanks

yep Burson had the dayco KT70 tensioner for 45 bucks so I grabbed it. They didn't carry the stud, washer and nut though so its just fingers crossed that the 8mm stud in my BJX head will be the right length.
I have the IE spacer that is meant to prevent the tensioner crushing when its torqued up which I guess will take up a bit more length on the 8mm stud.....we'll see I guess.
