A little real-world experience:
Regarding the aftermarket hydraulic TO bearings: I’ve had multiple failures with the McCleod product. I’ve had multiple successes with the RAM product, most notably in our SIII eType.
It does not mount to the bell housing, it sits on the nose of the trans. There is ususally an anti-rotation pin that goes in place in one of the studs on the front bearing retainer (on a T5.) Not sure about your application, but you’ll need an anti-rotation solution.
I am not sure what your gearbox looks like… If the bellhousing is integral you are in for an adventure because it will be very difficult to test fit and set depth…EDIT: Actually maybe not. Would need to build a device to measure depth from block mating surface to clutch fingers, then measure from bellhousing mating surface to TO bearing face… doable now that I think about it. Knowing those dimensions is how you set the bearing distance out from the nose of the trans so it almost touches the clutch fingers.
Get the remote bleeder kit to go with it, it’s a simple braided line. Bleeding is a non-event.
Make sure you understand the bore and stroke of your clutch master cylinder, and compare it to what the TO bearing manufacturer calls for.
Fuel line is not hydraulic line. Use hydraulic line. Like from the remote reservoir to the clutch MC.
All the usual suspects (Speedway, Jegs, Summit) sell a depth tool that will help you properly space the bearing out from the front of the trans so that it is the right distance from the clutch fingers. Get one, understand it, use it.
If you go with a stock clutch MC, you’ll have a bit of drama finding adapters to the normal US-spec pressure line on the TO bearing. I don’t recall the details, it’s been 10 years, but we finally found one.
Some manufacturers (RAM) say that the clutch release point can end up high, near the top of the pedal stroke, even when everything is properly set up. They sell an in-line height adjuster to rectify this. We had no such problem, release point is about 1/3-1/4 of the way up from the floor, feels just right.
Been in the car 10 years, driven pretty much every week, zero issues. I plan to use same setup in my XJS once the zombie apocalypse abates and I am more comfortable with my bank account.
