300TDi Timing Belt procedure

So, I've got a few projects that will result in removing the entire breakfast and I/C and radiator setup.

While I'm there and have easy access to the timing belt, I'm going to replace it.
I was told it was replaced in 2007 (about 20,000 miles ago), but who can be sure.

Anyway, I did the "search" and found many many threads on 300TDi timing belt issues, but there's gotta be a thread with complete procedure or a link to a shop manual document.

Anyone have anything? it's not like I was being lazy and didn't search, just that after the 10th page of hits, I was thinking there has to be an easier way.

Also, if anyone out there wants to unload a timing belt tool kit (after using it once) I'll buy it instead of spending $120 at RN. Alternatively, if anyone wants to preemptively "lick" a tool kit so that when I'm done using it I can pass it along to a board member for something lke $75...... I just know it's going to be a one-time use for me. Open to borrowing one too if anyone trusts me

Ouch- 7yr old belt.

http://www.landroverresource.com/doc...nual_96_on.pdf

Or google Service repair no - 12.65.18

In the manual Section 12. Job is very simple on a 300 since water pump etc don't have to come off. Breakfast etc don't need to be removed just fan clutch and shroud.

Issue with belt is usually age not mileage. 5yrs max or 50k- whichever comes first. Anything beyond is borrowed time.

You are living "on the edge"

I found the DiffLock Article the most thorough.

I agree, Difflock. The toughest part is the crank bolt. I mark mine where it sits, put a socket on it & a breaker bar, and smack it with a 2lb sledge until it moves (loosens) and then when done I re-tighten to the same place. I've changed mine twice, no problems.

thanks Zack.
Doug was already kind enough to send that link, so I have the workshop manual.
the Difflock article was "404 Not Found", so maybe they moved it.
I'll be placing an order for the kit with RN within the next week or so.

THanks Carl for sending the Difflock article. Pretty comprehensive.

Does anyone know if I need the "early" or "later" timing belt kit and what the primary differences are among the two?
My 300TDi serial number is 121 35697A
there may be an "E" after 121, but it was dark last night when I looked.

Post the difflock article here for posterity. The later crank pulley has a lip on it to keep the belt from "walking" back and forth. Early engines had an issue with the belt walking out into the front cover face and sometimes you open the engine to find piles of rubber shards in the front cover and not much belt left. Most all 300's have had the "upgrade" by now. I always buy the later.

there is also an upgraded bracket supporting the rear of the injection pump. This is for really early engines like mine. I changed to the later style pulleys, had to change the belt again after 20k miles as it was still creeping forward.

Man I still think someone jacked with your engine. Why else would it have been pulled apart like that when we picked it up....

The DiffLock article is 3 PDFs @ about 6MB. I'll combine them into one and shrink them then upload here.

You wouldn't happen to have a picture of the update bracket would you or how to identify the right one? I'm not sure which I have and have it all apart right now and would like to put back together with the right one if possible.

Quote from AULRO

"The pump bracket is hard to describ the mod, but here is go...

The old style rear pump bracket was just a plate with holes drilled in it.. the new one is a plate with oversized holes and push in sleaves that your bolts go thru.... like an alternator bracket...."

image here (you can buy it there too...I bought mine over the counter from Keith Gott LR's when I was there in 2009 with our Uncle Douglas)

FYI You'll need longer bolts...

Zack, I've heard these are known to have the front ring fall off the crank gear, so better to use the newer style that are made from one solid piece.
