Tappet adjustment

[ticky]

hi
I know somebody did a step by step tappet adjustment Thread on here but I cant find it. I havent adjusted tappets since the early 70's so Im a bit out of practice.

I notice there are a few queries about Tappet Adjustment lately probably because people have a bit of time off and can do a few jobs on there cars.

I was wondering if this thread, once found, could be a Sticky in Mechanical

Any recommendations of mechanics in Melbourne east or south east with experience on NX pajero tappet adjustment?

Thats a fun job!

don't forget to replace your chain guide when you do the tappets. it is a lot of work to get into the rocker cover to not do a cheap wearing part IMO.

Chain guide is not a problem from the NS on.

I’m not sure about that, this recall site has models listed up until 10th March 2014 (i.e NW) listed on the timing chain recall.

Yes that's correct.

It's for the tensioner not the guide that gave trouble in the previous model.

Hi,
I never said it was a problem, i was only pointing out that since you are in the vicinity of the guide, you may as well replace it IMO. its cheap and easy to do.

I'm not saying to replace the tensioner etc.

if you book it in to be done at dealer etc, they generally do this guide anyways. it is a consumable and its a lot of effort to get to it so why not?

Ok. I give in.

I learned something here!

So earlier (pre NS) there were guide issues but later (right up until parts of the NW run) there were tensioner issues?

the guides on NS and later weren't necessarily failing, each case is different on how bad the tensioner got i assume.

It was just good practise to at least inspect the upper guide and or replace them if necessary seeing that you have completed most of the work to gain access to the guides in the first place. I am talking about the upper guide specifically.

here is a well documented thread about it.

Sorry but that is useless on a Gen 4 as they are common rail. Ours has done 320,000ks and yes we had the tensioner replaced under the recall.

Have never heard of a guide failing in the Gen 4.

[GHendo]

I don’t know it the top timing chain guide on the Gen 3 and 4 are the same – they probably are, however the original guide that was failing on the Gen 3’s was replaced with a new guide with a completely new part number – the number now is “1140A026”.

If the later models don’t have the problem, it is probably because they came out of the factory with the redesigned chain guide.

Way back in 2012 I replaced my guide when I first read about the problem (I have an NP), and the new guide looked a bit different to the one I removed.

As I am about to do a valve clearance adjustment, I strolled into the local MM dealer the other day and asked for a new top timing chain guide as I thought I’d put a new one on while I had the cover off – just like the Irishman – “to be sure to be sure”. To my amazement, the $24 part I purchased in 2012 now sports a price of $61.72 !! I told the spare parts guy he was nuts and he said “No, they skyrocketed the price of those things a while ago now.” Talk about a bloody rip off.

Anyway, I suppose if it a small price to pay compared with a complete engine rebuild.

Hey Geoff,

that was kind of what i was trying to get accross.


It doesn't have to be replaced, nor am i suggesting they fail, its just a lot of effort to get under the rocker cover so why not replace it!

even at the new price it is still worth it i reckon.

If i did tappets on any vehicle with a top guide, i'd still remove it and at the very least inspect it, regardless if its known to fail or not. sometimes, things just fail.

[basil]

That is amazing Geoff.

I was in there about a year ago, and just asked the question about the guides being an issue, as mine was perfect still at 180,000, and his reply was " here ya go, have one on the house and you may as well have a tensioner in case you ever have an issue, but you shouldn't". We have given hundreds of these away.

My how things have changed.

Cheers,
