Time marches on

Putting things back after taking them apart is just the reverse of taking them out which isn't very exciting so I will skip most of it, this time 

If you are interested take a look at the post https://landroverkaty.blogspot.com/2022/09/fault-finding-and-removals.html and consider doing it all backwards 

The only difference is of course that you are fitting new components and gaskets such as the one that separates the steel of the injector pump from the aluminium of the timing case 

New pulleys and tensioner inside the timing case, new crankshaft oil seal and then set everything in the position that you need for the timing to be correct (there is a pin that fits through the injector pump, a mark on the crankshaft pulley and a notch in the flywheel) and then reassemble the case, fit the crank pulley and the fan pulley (gicing it a hard whatck to ensure that it's on properly) and then the fan belt. Connect everything up again, Check the tappet / valve clearances because the rocker has been off and she's ready to be started.. so how did that go?

Fault Finding and Removals

Having found the mess inside the timing cover the next steps were to start removing parts to see what was the result, 

First off was the timing belt, cut through with a blade it was easy to spot the faulty part  which had been stripped and almost broken through

Then some more investigation under the rocker cover to see what damage there may be. On first look things are at least oily and together

But on checking them (one at a time to keep them in their original place) two were discovered to be not a straight as they should be . 

So two of them were added to the parts list I need for the rebuild. next step was to get the injector pump off and send that to a specialist to see if that was the root cause. First step detach the pipes to the injectors (which I put caps on to stop any dirt getting in)

Then detach the pipes from the back of the pump and remove them

 Which gives access to remove the electrical connection 

Then remove the fuel pipes going to the unit

And finally the three bolts at the front and the ones at the back as well 

And it's free

A bit of wrangling and it's out and ready to send to the specialist 

Bad Times

Per the last post where we  we had an awful time getting home from Tebay Services It was time to start the investigation 

After getting the fan out of the way it was a fairly easy process to remove the fan pulley (given everything was locked up there was no hassle stopping it moving. Simply put on a long bar and remove the nut

Then work all the way around the timing case and remove the bolts from the case and it simply pulls off with a sharp tug

What was shown was an absolute mess where the timing belt had almost fully disintegrated 

Whilst some of the teeth were still in place on the belt, others had been stripped off and had been transformed into all the fluff that you can see on the inside of the case in the picture above, and between the pulleys in the picture below 

The next job was to see if the injector pump was to blame (as was suspected because no fule was coming out of it) so with the belt cut a power bar was put on the nut at the end of the pump (bottom left) and an attempt was made to move it... It was solid! 

So it's got to come out to be sent off to a specialist.. That's going to be the next story 

MOT 2015

This year's MOT has not gone without cost and hassle 

What's missing from this picture is the injector pump which has had to go off for refurbishment as the seals were leaking and that means diesel is getting out into the engine bay which I am sure you can agree is not a good thing 

 But in doing it it was noted that the tensioner pulley for the fan belt was seized and that means a new one so that's off as well, a nice and simple job of removing the single bolt that holds it in and it wasn't even seized or anything and came off really easily

It was also noted that the bearing in the timing plate cover was rumbling and it would be a major cost and hassle if that failed and sent parts of the engine crashing into each other so that's been replaced as well 

Luckily all the other bits that were exposed during the exercise look to be in good condition and will be able to be reused along with a new set of seals and a nice new gasket to keep it all sealed and clean
