Timing gear replacement

Post by TonySmallcar » Mon Mar 20, 2017 3:31 pm

Hi All.
I am a new and very proud owner of my SE5a which is something of a rolling project.
The timing gears are making a terrible noise (bag of nails in a washing machine) and there is a hiccup at heavy acceleration so I have a feeling they need changing.
I can't see a receipt for it being done before in the mountain of paperwork I have, figure it needs to done anyway.
Unfortunately I don't have the set up to do this on the driveway (primarily as i don't have one) so will need my local garage to do it. I have a good relationship with them and use them for our work fleet (of classic minis), however we can't find a guide for the labour time needed for the gear change.
Can anyone help give me an idea of man hours involved? I'm sure it's nowhere near as quick and simple as it looks.
Cheers
Tony

Doubt very much it will be timing gears, unless it has the made in a shed with an angle grinder and hand drill type of steel replacements fitted in the past.

I have heard these gears fitted and they can be very noisy.

In my experience of Ford timing wheel faults they either work or don't, nothing in between.

It`s more than likely the petrol pump studs are too long and one is rubbing on the timing gear.

Incidentally, Ford fitted studs with only just enough UNC thread to fit the alloy cover without protruding into the insides, but I have seen bolts used instead of the studs and these can be wound too far in.

So I would look at the petrol pump mounting first before spending shed loads on timing wheels, which if they are replaced by metal or alloy ones, should be matched to the crank nose wheel/gear.

Are you 100% sure it's the timing gears? The original ones are silent; steel/aluminium replacements can whine like a supercharger. Something rattling like nails in a washing machine sounds like it could be idler pulley bearings (or a dying water pump or alternator) - test by dropping the drive belt off and running it for only a few seconds (as the water pump won't be running).

Could also be the fuel pump studs/bolts..

Thanks all. Thew alternator is definitely noisey and due for replacement this week, I will check the rest whilst there.
It would be great news to hear that i don't need £150 quids worth of alloy gear!

While it's always a bit tricky to diagnose other people's noises, from a description, I tend to agree with the others, that your symptoms don't really sound like a timing gear problem.

*However*......

To say that means you don't need to replace your timing gear, would be going a bit too far. That would only be true if you've already got a steel or alloy replacement. If you've got the original fibre or nylon types, then you really should be budgeting for a steel/alloy replacement in the not too distant future. Think of it as being like a timing belt, which you would have to replace, except with our cars there is no need to keep doing the job - the metal gears are an everlasting replacement :)

[ps. You can check which type you have by removing the petrol pump and looking in through the hole.]

Alternator bearings can be re-greased or if too worn can have new ones put in.

I've replaced the idler pulley bearing on an 80k mile engine,loud rattle/knock was the reason.
Take the belt off and spin the pulley by hand to confirm if the bearing is the source of the noise.

Can be done in the kitchen.......however solid granite worktops no good....wood/composite better so you can drill the holes to fit a good vice (temporarily of course) :shock:

There's a few guides on here if you search (perhaps one could be moved to the "how to" section?)

this one for example.
