URGENT: 300Tdi Broken Drive Belt!

[Treads]

I just had my main drive belt let go on the way back from town. I suddenly felt the steering go tight, tacho drop to 0 and the battery light came on. It was still running fine so I kept driving about 1km home through only two turns and switched it off in the carport. Checked and the serpentine belt has snapped.

Question 1: Would it have done any damage driving home?
Question 2: Should I perform any minor maintenance before I put a new belt back on? (ie water pump, idler pulley, etc)
Question 3: Since the LR guy who serviced the car before I purchased it can't be bothered ringing me back to confirm when the timing belt was last done, should I change it now?

Thanks

Change the belt strat it up, if it runs turn it off ,and go have a beer. Oh yeh check your belt regularly and change it before it breaks!


( Did the temperature gauge go to the red? (thats an important component of your quandry))

[Treads]

Thanks for the reassurance!

I only checked it last week after returning from a 4wding weekend :(

She was cold and had only driven about 2km when it happened. otherwise I would've switched off and pulled over straight away

After 2 Ks you should be fine. 20 or 200k's, and a hot motor, it would be of more concern.



Consult a manual for the correct path for the serpentine belt, you should be able to find it here on the forum if you search for it.

No damage from driving without a belt (other than sucking a bit of juice from your battery). There is a possibility that the belt can damage things when it breaks, so check radiator, intercooler, etc, etc for visible damage.

Thanks mate, got rave open on the screen right now ;) Going to pick up a new belt from the local mazda (& ex-LR) dealer in about an hour. $61 in stock, that seems a decent price.

cheap insurance to have it changed if you do not have the history of the car, got mine done in jan for approx $700

my rig has been changed every 80 000km

I was guaranteed that it had been done recently, but the mech doesn't seem to like returning calls to confirm :mad:
I was going to do it myself. It's probably fiddly, but I've got the rave CD and plenty of time ;)

That way it should only cost me +/-$250. I'm also doing the idler pulley bearing while the belt's off, $6 at repco (in stock too) More cheap insurance....

I would check you power steering pump and make sure the pulley/shaft is in its spot. Belt failures (on good belts) are usually caused by the PAS shaft coming forward causing misalignment due to the bearing failing or shaft breaking.....just supplied 2 pumps today due to this fault.

Just take belt off (:( already done for you) and move the pulley in and out, if it moves in and out you need a new pump.

If you can't confirm when timing belt has been done and you plan to do it yourself then go for it. Takes about 6 - 8 hours first go depending on how handy you are. It does help having a monkey and make sure you use the right torque for the belt (11nm).

Replacing the bearings on the idlers and tensioner is pretty easy. Remember to get 6203 bearings that are double lipped seals. Provides better dust and water protection. Dearer than $6 though.

Treads ,just did my idler bearing replacement make sure you have your sense of humor when you attempt circlip removal can be tricky to get out .
When you do get it increase the angle of the bevel to make it easier next time.
On the parts cost side of things just got my belt for $44 along with service pack filters etc and then had them posted to me postage $6:D saved 50 to 60 bucks just by ringing around! If ya have time that is!

Codboy,

Are you willing to share as to where you managed to get the deal?

Yeah I rang Repco and they quoted me $6ea for 6203 bearings. Maybe there's different types?

NTK 6203 LLH C3 or 6203 RS2 C3 from memory.

driving a 1 km down the road may no have done any damage however bear in mind that the Serpentine Belt drives your water pump which pushes water thru your cooling systems , assuming coolant levels were normal and there is plenty of coolant inside the engine , it needs to circulate thru your radiator to keep things nice and cool, without that serpentine belt the water pump won't operate.

Slug_burner , had them sent from British off road landsbrough qld , if in bris vegas also try MR Automotive at redcliffe same prices same excellent service !:D

[discomuzz]

Totally agree!!! Happened to me, but I ignored shaft movement in PAS pump. Bad move, next time the belt went (2,000ks or so) it wrapped itself so tightly around the water pump shaft it stuffed the inner seal on the unit!

Of course, I didn't find out the water pump was stuffed until I put it all back together and ran it.

This little mistake cost me an extra belt and a water pump, not to mention a weekend.

Also, was advised by a LR mechanic that the main belt could take out the A/C belt when it goes and that, in turn, can slice the control wiring on A/C compressor, which is unserviceable (i.e. new A/C comp.).

So, check the PAS pump shaft for movement!

Mine did the same with a seized idler bearing when the wife drove to Sydney. She told me after I flew down that it was making a funny noise:confused: Sometime the day before.
Check all the pulley bearings and replace if required as i found that they deteriorate at a similar rate and fail one after the other.

When I did mine I filed a slot to make future changes easier. Its at about the 7 o'clock position

Hi treads....

there are a number of 6203 bearings in the front serp belt & timing belt idlers etc - my advice is to replac any that you have apart

also be sure to check the state of the fan pulley bearing in the front cover as well while you have it apart

if you go ahead with the timing belt replacement you will need a specific crankshaft holding tool & a specific pulley puller, (& of course the timing tool!) - these can all be fabricated if you don't have access to them

you'll also need 3/4 drive +27mm socket for the main pulley bolt

it seems that I might not be too far away from you so give me a pm if you need further advice/assistance

regards - Laurie:)

yep... 6203ZZ is one of the sealed ones

Thanks, I put a new bearing in the idler pulley and put a new belt on this afternoon after checking all the other shafts etc for play

Appreciate the advice and the offer of assistance, however I think I may leave it this time and get the LR specialist in Raleigh to do it. Spoke to him yesterday and he quoted $600-700 to do it. I've got family near there and travel down the Waterfall Way a lot so it won't be a problem. If he lets me watch a bit I might do it next time, this is the first vehicle I've had that I actually enjoy working on ;)
