Timing Belt - MN GLXR

Postby neville75 on Sun May 03, 2015 7:30 am

Hi Folks
My 2009 MN Glxr has done 40,000km. Had annual services done and now due for the "75,000"km service. The service manual states that timing belt should be done at 75,000km or 5 yr which ever comes first. Mind you, it also mentions platinum spark plugs at 100,000km much like what's in my magna service manual, clearly for petrol vehicles.

My question is does the timing belt need to be replaced, if so, should I just get the timing belt replaced under the 5 yearly interval or would you expect a 40,000km timing belt to last a bit longer?

My 07 Petrol is timing belt 90K & sparkplugs @ 100K. I would go with what the log book says as not being a mechanical person can't afford for it to let go when out wheeling.
But everyone makes there own risk versus reward type calls. It is expensive that is for sure.

Hi Nev,
Mate, I'm sorry to say but, you're asking an "un-answerable" question there, you know, a bit like asking 'how long is a bit of string'....? Putting it simply Nev, there is no 'right' answer to your question.
For example if I was to say "yeah no worries Nev, she'll be right to leave it for another year or two until you clock up the full 75,000 Klicks before you change it" and you took my -"advice"- and -somewhere- short of the full 75Ks your timing belt -broke- and resulted in -catastrophic- engine failure, or far worse, catastrophic -loss- of -your life- because, of the catastrophic engine failure occurring just as you planted the foot, to turn out across the path of a fully loaded oncoming Road-Train bearing down on you at 100 Klicks.... :shock: what would be your last thoughts about my -"free advice"- about the safety of ignoring the manufacturer's recommended change interval for your vehicle's timing belt...?? .... :o
I'm sure that your last thought, wouldn't be -"printable"- here.... :lol:
I'm sure, that the manufacturer builds in -"A"- safety margin ie, they wont themselves risk, having you run their timing belts -"to the edge"- of their -"failure"- limits with their own recommended change interval -"BUT"- just how -"fat"- is that safety margin....??
That's where it becomes the 'how long is a piece of string question' Nev....!
Mitsui make the 75Ks -"OR"- 5 years change interval recommendation -"for a reason"- if -"YOU"- should choose to ignore it, then the -"RISK"- of doing so, is entirely upon -"YOUR"- shoulders.
IF YOU DO decide to "push the limits" Nev, then be sure to remember that last point, when you've got your whole family loaded into the car, and your sitting there impatiently, waiting your chance to "give her a boot-full" and turn out in front of the path of that fast approaching, fully loaded Road-Train.... ;)

Thanks for the very reasoned viewpoint. I'm sure there is a margin before the rubber band snaps, but probably best to err on the side of "not being a tighta$$" and get it done. Now I've just gotta find someone to entrust that surgery to. Wouldn't give my local dealer my pushbike to service, let alone the triton.
Thanks again, Nev.

That sounds right. 75k? Not so sure unless it was time based as well.
The voices in my head may not be real, but they do have some damned good ideas.

If it's feral, it's in peril.

MN turbo lag? What lag??

My dealer recommended combining with the 105,000 as its a relatively minor service. The 90k is exxy, and 10k too early

The whole rubber band saga has really thrown a pain into the engine maintenance equation.

In some cases manufacturers have nearly halved their original replacement schedules due to unforeseen failures.

Then in others its as mad as the 3.2 having to disconnect the fuel system to get at the valves, where major surgery has to take place to get at it.

With relatively slower revving diesels the good old fashion push rod setup would offer some benefits.

Mine snapped the balance shaft belt just after 75000 kms. It wasn't oil soaked from an oil leakage and I don't rev the engine hard..... Maybe that's why! :lol:

Decided to go and check my own MN Mitsui Service Logbook "biggi" and yep, for the 4D56 it says "Timing Belt - Replace every 100,000 Kms -OR- 5 Years, whichever occurs first" .... ;)

This thread just reminded me mins due again in at the 245,000. Yes, my old dealer didn't replace it at 100,000 when he was supposed to and I forgot about it till it hit 150,000. Wish the aftermarket belt kits were trust worthy as would safe a few hundred dollars. Atleast by not using a dealer I will save on labour $

Why wouldn't you trust a dayco or similar aftermarket kit?

I bought a set of dayco aftermarket belts (not timing but the other two) and only one of them fit. That would tend to put me off for something as important as timing.

My mechanic who does alot of tritons said he has a few probs with the after market belts not being the right guage. After hearing that and then seeing a similar thing from another member here on the forum, I will not risk the timing belt on an after market jobby to save a few hungie.

My drive belt and A/C compressor pump are after market and fit fine.

Also, the Dayco timing belts that I've seen advertised on flea-bay are only 'warranted' for 3 years....! :shock:
So I'm with you there "biggi" when it comes to the timing belt, I'll happily pay the extra few 'folding reddies' to Mr Mitsui Stealer, for the "real-McCoy" version, complete with the 'real' Mitsui warranty on it.... ;)

Definately repalce at 5 years or 100000km, WHICHEVER COMES FIRST

have seen a few of these break over the years, more so the balance shaft belts than anything, but noen the less, it can still be catastrophic if it breaks.

Definitely should go genuine on items such as timing, esp with interference valve setups, as the the aftermarket "belt teeth" may be out of phase. :evil: :lol:


Seriously, if you can find an aftermarket unit with the same construction and warranty there shouldn't be any problem. Sometimes a haggle with a dealer can just about null out any cost difference with third party gear.

Replaced mine at Easter,Dayco kit KTA-281H,according to the box it meets or exceeds OEM requirments.All the idlers are NTN bearings and the kit delivered to my door in Victoria $375 from Western Filters in Sydney.Is it better than genuine,i don't know.Is it a second grade product? Wouldn't think so.
