MT75 parts help needed
Posted: Tue Jan 30, 2018 9:16 pm
Hoping folks can help with a general question regarding MT75 parts. Background is I am not aware of any North American Fords that used this gearbox, so finding the various donor cars confusing and can?t be sure what I have.
We have my Spyder supplied MT75 in bits right now. I need to source some very standard spares for it, including a bearing kit, synchro (baulk?) rings, and seals. I contacted Sean at Spyder and he emailed me two parts drawings (without the part names attached ) and said to just tell him what I need and Bob?s your uncle.
Trouble is the one drawing he sent looks like a three rail top mounted shifter and is marked Transit, rather than what I have, which I thought was from a second generation Ford Scorpio, 1995 to1998 with a single shaft coming out the rear of the casting (no shifter hole on top of the casting). The pictures in the on-line Scorpio MT75 Repair Manual look like my gearbox, although I am not sure on the starter motor location (mine is on the Lotus TC inlet side and fits my Spyder chassis fine after minor modification). However, the Scorpio parts drawings on the same site show a completely different casting with the shifter on top?

The other Spyder supplied parts drawing of the gearbox internals shows all six baulk rings as the same part number. The Scorpio Service Manual references running changes to the synchro design (bevel angle on selected gears and a different first/second set-up) so not sure what I have. We have not taken the shafts apart yet and I am not doing the work, just trying to get the correct parts. Ideally I can figure out what we need and get it here before Malcolm pulls the shafts apart.
Every bearing and seal kit set I look at does not call up the Scorpio. Further, I understand there was a different car in Europe called a Scorpio that was called a Granada in the UK? They generally reference a Sierra as well. The other popular MT75 callup is a Transit van, but that seems to have a completely different bell housing? We never got any of these cars over here, so completely confused! We did get a car called the Merkur Scorpio, but it used a T9.
I am OK with ordering the parts from Sean if required, but would like to try to just get a few standard rebuild kits (bearings, baulk rings, seals, O rings, etc) if they are available. I don?t really know what to ask for in terms of donor car, and we did not get an MT75 in anything I know of in North America. I may even be able to get parts from my local Ford dealer if I can figure out what to ask for. I have been looking on the net, primarily eBay UK, and am totally confused.
A last general question regarding gearbox overhaul. The bearing kits seem to include the main shaft bearings, but not the smaller roller/needle bearings associated with each gear. Are these normally renewed during a rebuild, or just on an ?as required? type deal? I am thinking we should be able to match these up locally? I did see a remark in the inter web that these are prone to making noise if there is shaft wear.
Any help appreciated. Maybe a suitable Ford parts supplier in the UK that I can call? The Burton selection for the MT75 is pretty limited and also doesn?t reference the Scorpio.
