Hydromount

[willster]

I've finally made a steel tube tool to remove my perished hydromount on my diesel tourer. I had planned to do this job in my flat garage but I can't actually get in it at the minute due to a load of Sleepers and soil blocking it left over from a landscaping project.
My next thought is to try and do this on my drive. My problem is the drive slopes a fair amount, Will this affect things when trying to align the engine?
I would say the slope is probably 400 mm over the length of the car between the wheels.
Also does anyone have a average time this job will take me I know it's subjective and depends on a lot. But saying I'm fairly competent and don't run into any issues how long would one say for this job? Just wondering how long to allow, I've guessed at 2 hours fairly leisurely?!!? Thanks all, also offering up my tool I built for members needing one when I have completed the job, you pay postage or collect return. Thanks, Will

Hi will,
I’d say 2 leisurely hours is about right, but when I done it, I had help of a 2 post lift.
The slope of the drive may make it difficult to align the rear engine mount, which from memory I also removed at the same time, unless you jack the front up to make the car level with the rear.
If you had a set of Ramps (about 400mm high), you would have little or no “jacking” to do.

Yes thanks for the response. I might try that, I could jack up the front and drop it on a couple of sleeper ends might bring it about level and like you say won't have to jack the front to loosen the bottom mount. I'm fairly confident about doing it but haven't ever loosed the engine or jacked it up so slightly nervous but probably worrying about nothing. Just don't want it stuck on drive in bits so to speak, supposed to be heading down to Cornwall next week in it!

The job will take you almost 3hrs if everything goes to plan, in your case you will first need the car to be level, the car needs to be on ramps or raised at the front, this is to aid the dropping of the lower engine mount.
1

Chock the car at rear wheels with handbrake on, put the car in neutral gear, and remove the engine tray another reason why the front needs to be in the air.
2

Drop the lower engine mount no need to remove it, loosen the top bolt large one, and remove the small bolt bottom.
3

let the mount hang loose.
4

Use a trolley jack to support the engine, have a piece of wood between the sump & jack
5

Remove the engine cover.

I need to be careful here its turning into an how on someone else thread

any way up shot is there is quite a bit of work required & parts to remove to get to the mount, snaps shots below.

Thank you for such a detailed and helpful response, I was already planning on following your excellent how to on this. I have a brand new undertray I havevent fitted yet so that might save me half an hour. Thanks very much I will probably tackle it Thursday and report back.

Well i did it, tried to attach an image but it wont let me. Im glad i did it because the old one fell in half as i removed it. My made tool wasnt as effective as i thought as the old one was well stuck on. It was stainless tube and the teeth seemed a bit soft, i was bending them a bit and also damaging the castelations on the old mount, so in the end i ended up knocking it round with a hammer and chisel , it took a lot of force but i got it off and all sorted. Re aligning the engine for the large casting was quite tricky and i had to use a big spike in the engine lifting eye to get things lined up .All in all not to bad and it has made a big difference , much less vibration in cabin and seems smoother through the gears, i cant believe how well it does drive for its age to be honest .
Thanks for the helpful words and advice given , i would not be running this car for the last 8 years and enjoying it without this forum .

When removing my mount I used an Oil Filter Strap Wrench like this:



Also plenty of Plus Gas!

I wasn't aware of a special tool for removing them!

Is there a specific torque required when refitting or is it just a case of as tight as possible?

Yes, Rave says 85Nm.



Should have reduced the size of the above pic. - it looks huge on my monitor. Oh well, can't be bothered to upload another one - all that mouse clicking and key pressing.

PS. Hydramount on KV6 is Rave page 409 / 12.45.12. Torque for Hydramount on Diesel & 1.8 engines is 85Nm too.
