Post subject:  My alternative to the clone TKC1044 Sprint gearbox mount.

If you have been mad enough to read my restoration thread, you will have seen that I replaced my gearbox mount to cure a violent judder (very similar to axle tramp) when setting off. Now I was quite disappointed by one aspect of my work, though the judder was cured, the cabin noise was more track day car than smooth cruiser to put it mildly. All of the engine, gearbox and exhaust (which is bolted to the gearbox) noise was so loud that I took everything apart to check my work but without change.

I have a spare mount that whilst old has not yet jellified with oil contamination, and with that you could move the centre by hand in all planes relatively easily though harder to fore and aft. Not so with the replacement mount, I could not get that to move even a jot when it was bolted up and had some weight behind it. So I set about looking for a replacement, and read on here that a Sierra Type 9 mount had been successfully used. They seemed a bit expensive for an experiment, anything from £24 to £45, and needed quite a bit of fettling on the crossmember to enlarge the aperture, so went looking for something else.

A visit to the local motor factors and a rummage through their catalogue came up with something that was not a million miles away from what I needed, and was still being made by the OEM supplier, a Febi 22394 which says on the box "To fit Volvo PKW", total cost £8.

Comparing the Febi with the TKC1044 more closely showed a few differences in dimensions, which I'm sure is not going to surprise anyone who has read this far. Well done for that by the way, this has to be driest thing I've written since my thesis on the the Atacama Desert, which didn't actually happen but I'm using it as a writers device *cough*. With the Febi mount there was give with fingers alone in the fore and aft directions, but nothing left and right, which whilst the opposite of my OEM mount, seemed more logical, very little twist, but allows a little push and pull movement. Fetched my crayons and vernier calliper, and come up with some (un)helpful pictures to show the differences, first dimension shown is for the OEM TKC1044 followed by Febi 22394.

Not wanting to ruin my existing crossmember, plus I could mess around with this idea and keep using the car at the same time, I took the crossmember off my spare gearbox, it was a tad rusty.

Actually that doesn't look so bad, let's have a look at the other side then.

Can't even imagine putting that on my car, it might catch something! Took a walk to Wilkinsons and bought a wire brush for my drill, some rust converter and a rattle can of Hammerite £16, that place can be stupidly cheap sometimes. A little bit of spit and polish and hey presto, one cleaned up crossmember with 5mm elongated mount holes done with a round file.

As the Febi mount height is 9mm lower than the TKC1044 I made some shims up from 40mm flat washers, just needed to drill out the centre with a 12mm drill bit.

And et voila! The finished crossmember with new mount ready to be bolted up.

Took the original crossmember off and was dismayed to see that the new TKC1044 mount's aluminium centre had already parted company with the black stuff pretending to be rubber that I think is the same stuff that they seal road joints with. I just plain do not understand how no one else has the issue that I did with it noise wise, maybe I've just been unlucky with a bad batch?!

Bolted on my new crossmember, using only 6mm of shims to get the right height, all looked good and fit together well. Put away the tools, cleaned up and went for a test drive, pulling out of my drive extremely cautiously at first I must admit, but already with just going down the side street it was so much quieter, and so it proved to be as I continued driving with gaining confidence, total and utter bliss, and no judder still.

Good grief I thought, this has actually worked!

Congratulations! We need pioneering work like this to keep our cars on the road in the face of inferior quality replacement parts.

Excellent work here, so its a Volvo 740 transmission mount?

All you had to do was elongate the holes by 5mm and fit some washers to shim it up?

I'll buy you a beer if you're at the NEC next weekend!!

Ta for the thumbs up Pippin!

You know what James, I never thought to do a reverse lookup to see what it originally fitted! Here is the list from a quick google Volvo 740 87-92 B230 (automatic only), 760 87-90 all, 780 all, 940 91-95 (automatic only) B230.

And yes, quite embarrassing considering how long my post is, the TL;DR is elongate holes by 5mm each towards the centre, shim out with washers to suit! :lol:

Superb effort, Sir!

How about we send you some spare cross members and you start a new line for Club stock? :wink:

Rarely in the field of dolomiting has such an excellent solution been found for so little effort.

The few of us left who use our cars a lot will now be clearing out NOS of these mounts so be quick everyone...

Is indeed, there seems to be a lot of Volvo part numbers for the same part, I see down at the bottom it says MPN 22394 so spot on. Volvo part numbers I've found are 982793, 1330831, 30812002, 3528069, 3528070, 946440, 966807 and 974209.

Seen this one on ebay at £4.81 delivered and they have 10 showing!

Meyle do a heavy duty version if the OEM one is too soft for you:

Ha! Not sure on the long term future of this career change, it seems to be a little limited! I'm quite sure that you are all more than capable of doing your own, but in all seriousness if not then I'd be happy to help and mod one.

Gave a mate a lift tonight and without me saying anything they straight away asked what I had done to the car it was so quiet. Glad to give something back, but hey, maybe prudent to wait a bit just in case I come back to the forum with a sad tale of how my gearbox has just dropped off! ;)

Well done Raf. I'm sure you've put it on correctly. You should be able to do it in your sleep. Wilko is a good place for stuff. That's where I got my vinyl silk from for the headlining. This is what it's all about - finding alternative parts which can be safely adapted to fit with minimal fettling.

I like it Raf superb. I never noticed the lack of voids in that horrible mount . I have only fitted original old stock mounts. I keep old original engine mounts because I know the reproduction ones cause problems and I have no faith in the quality of this stuff anymore. Top man Raf.

This is really interesting. I have never been able to obtain an 'OEM' mount for my car since I converted it to overdrive. I have replaced the mounting a few times in order to try and improve the refinement to no avail. It also judders (especially in reverse) so I may go down this route too before I get too carried away!

Well done!

Firstly may I add my thanks for the work done here, this really is a fine replacement for a poor re-manufactured unit.

But I would like to add one thing. You need to slot the mounting holes in the cross member to fit the mount. If you do this there is very little left and there would be a big risk of them breaking through when in use. So I will be adding plate to each side of the hole where the mount goes through the cross member to ensure it doesn't break through.
