Hi Folks

I was under Mable yesterday and noticed that the Prop looked kinked at the gearbox end, the gearbox to cross member bracket looks bent.

Any ideas as to what it should look like would be fantastic





Cheers

Darren

Crossmember is pretty thick steel and not easy to to knock out of shape. Your gearbox looks to be at slant judging by the way it is sitting on the rear mount, what condition are your engine mounts in, everything up front sitting square?

Cheers for the reply Raf

I was wondering if its the actual gearbox mount, as it looks slightly bent, I think I may have used tr7 engine mount rubber blocks, they looked identical as the 1850 ones I had were cracked.

Ps I can take some pics of engine mounts tomorrow

My 1850 gearbox mount looked a bit like yours. I was fitting an O/D box onto my car and the mount came with the gearbox, so I assumed it had got bent during removal from its original car, storage and transport. My car is jacked up at the moment so I'll see if I can get a photo of it today and post it here. There won't be any propshaft because I took it off while I replace the brake and fuel lines.

Is that an 1850 engine?
Which o/d 'box are you using.


I don't think the mount should be twisted like that.
To me it looks like a mismatch of mounting brackets for this engine and gearbox combination.
If it was me I would try to level it up.

Thank you for the reply gents

The engine is tr7 2.0 the engine mount brackets are 1850 with TR7 rubber mounts.

Gearbox is 1850 od single rail.

The gearbox bracket is 1850 od and came with the box. The engine is square on the subframe and level. It drives fine no knocks bangs or rattles. Just looks weird

Here are a couple of photos of my 1850 O/D gearbox mount I'm about to refit to my gearbox.
The top face at the back of the mount was set horizontal with a spirit level. In this state the long screw thread was at 90 degrees to the top flat surface of the vice. The left hand flange was pretty close to vertical in this condition About 5 degrees I estimate as the angle.
The right hand flange has an angle of about 15 degrees to the vertical.
The front bit is also horizontal.
Tony.

Here's what mine looks like. I tried and tried to get the left side vertical, and nearly got there but its very hard to bend it. The gearbox is sitting there quite nicely and nothing bangs on the body when the engine is running, so that's OK by me.

That's exactly how mine is. The bracket is also flush to the gearbox crossmember and rubber mount.

Here is another pic of the prop, should it be centre to tunnel.


Cheers

Must admit, your one looks way more cantered over to the right than Mike's. Must say that you're engine mounts looks twisted too but then I know nothing about TR7 engine mounts, or for that matter anything other than Sprint's! Well, that was helpful of me I must admit, I'll get my coat!

The TR7 lump is the same as a 1850 just a few more horsies, the engine mounts were from the 1850 engine that I had originally bought from Ian.

I wonder if I should see if I can get a pair of decent 1850 engine rubber mounts and see if they make any difference. Is there any difference between the 1850 and TR7 rubber mount block thingies



Cheers

Darren

Though the engine leans to the left, the gearbox is supposed to lean slightly right, to put the gearstick a tad nearer the driver than it would otherwise be. Why on earth they did this long winded mod instead of just bending the stick a bit is beyond me!

I had a similar situation with my sprint auto.

The prop shaft sits very close one of the tunnel and the Borg warner 65 sump pan was leaning to the right by about 5 - 10 degrees. I fitted new engine mounts, new gearbox mount etc. The mounting bracket fitted to the BW 65 extension housing is also angled so that the long bolt is perpendicular to the cross member.

After a lot of work I realized that the engine leans to the right anyway as can be seen when the sprint sump pan is viewed from the front in relation to the sub frame.

it works fine but to a keen eye it looks wrong.
