I may of imagined reading this in the past but is it true its cheaper to buy land rover service parts for the xfr? Filters, cam chain tensioners, guides and super charger coupler.

And... is there a jag guide on changing just the Tensioners and guides ( and not doing the chains)? I don't have chain rattle or any codes , so as preventative maintenance I was thinking of just replacing the guides and tensioners.

and is there a particularly good place to get ZF service kit, long life bix oil and diff oil.

Thanks in advance. 😎

 

Where is the vehicle located?

How many kilometres/miles does it have?

What is the MY?

What symptoms or DTCs are present to suggest the timing chain tensioners need to be replaced?

 

Hi NBcat
Shes done 78,000miles. No symptoms or problems... as said above, I'd like to do it as Preventative Maintenance...2011 facelift car

 

Which engine is fitted to the vehicle?

 

5.0 V8 Supercharged XFR

 

Depending on the timing chain arrangement fitted at the factory, some of the parts for the earlier cars are not available, so the primary and secondary timing chains, tensioners and guides must be replaced as a set.

Due to the extensive amount of work required to inspect the chains and tensioners, it may be best to wait until the engine exhibits symptoms before removing the cam covers to inspect.

The ZF gearbox should be serviced every 100,000 km/60,000 miles with a new pan/filter and fluid installed. Kits are available online from various vendors:

I didn't find that LR parts were any cheaper. I had to kind of compile my own guide for just changing the tensioners, guides, and blades, rather than also doing the chains, etc., as I used a variation of the zip-tie method and wasn't sure what all I could avoid doing which varied from the Workshop Manual. There were a lot of questions which I had, and I found a video on YouTube which answered a lot of the questions, but the comments section is where I REALLY got the most important answers. I put screenshots of the relevant YouTube comments section into a PowerPoint which ended up being about 77 pages long (I basically threw everything I could find into it). It was definitely overkill, but enabled me to successfully replace my tensioners, guides, and blades without any trouble - the anxiety about messing something up was the hardest part. If you want my PPT, fee free to PM me. Additionally, feel free to ask me any questions about how I did it, as I just finished it a few weeks ago.

Here's the link to the video, though...

 

Thank you so much Reaxions. Good to hear from someone who has actually only changed tensioners and guides. Did it make yours quiet ? And yes please 🙏 on the power point guide

 

Sent you the deck. Haven't driven it yet, since I'm doing SO much other stuff, but the chains definitely didn't jump any teeth, etc. So, if the timing was good before, it should still be good. I bought the aftermarket timing tools and used them, but I'm not sure they were necessary for just the tensioners, blades, and guides (except maybe locking the crankshaft, but I could've cheaply fabricated something to keep it from rotating).

 

For any and all ZF work I have recommended and used The CTSC a number of times.
They carry all of the ZF parts and OEM fluid for decent prices. He does not like to answer the phone but the owner Clause is a stone cold expert on all things ZF!

BUT there are a number of problems with the 6 and 8 speed ZF transmissions so I also recommend to take a look at Sonnax and their upgraded/uprated/problem solver kits.
Sonnax "ZIP" Kits

Since the 8 speed is also used on the Hellcat there is an unbelievable amount of aftermarket stuff for this transmission. I mean crazy stuff like billet main shafts and other hard parts.
