I am going to have to change the clutch in the B. All the shop manuals say pull the engine and gearbox. When I mentioned this at work, they all asked why I didn't just drop the gearbox out the bottom and go from there. Since this is the first time for this and me, I didn't have any suitable answer.

So will this way work, and will it be any easier?

TIA
 
There is a crossmember welded in place that will get in your way. It can be done, but it's a whole lot easier to pull it as one unit. Pulling an MGB motor and transmission is a relatively easy job.
 
Hi Matt, having done a clutch myself (albeit on a Midget, not a B), you might want to consider pulling the engine and transmission, since it's much easier to align the pilot shaft if you have both outside the car. With the Midget I didn't have the option of taking the transmission out by itself, but I only pulled the engine. Believe me, getting the two to go together requires near-perfect alignment, and it's not easy with one of them in the car. One tip though, Moss and the other suppliers offer a $3 plastic alignment tool for making sure the clutch disk is centered, and that's well worth it since it's the same size and shape as the pilot shaft. The transmission still has to be straight with the engine to go together, but they'll never go together if the disk isn't centered. Good luck! Oh, and even though my Midget shop manual never mentioned it, it helps to lightly grease the splines on the pilot shaft as the clutch kit directions recommended. You don't want lots of grease or it might migrate into the friction material, but a film does help things go together smoothly.
 
Thanks. Now I just need to solve the problem of where to do it and where to get the hoist.

I am reasonably good with tools, about how long should I allow to do the job? I would like to be able to get my ducks in a row, and pull then replace the engine in a day. Is that possible, or am I dreaming and need to allot at least 2 days for the hoist rental?
 
I think one day is reasonable, as long as you have the engine ready to pull that day. Get all the things removed that need to be removed (hood, radiator, starter, carb, exhaust, fuel lines...) ahead of time, and make sure you can loosen all the bolts. Looking at the diagrams for the MGB release bearing it looks pretty straightforward to replace. Mine required taking a trip to the machine shop to have the bearing pressed out and replaced. Have a helper or two to maneuver the engine in and out, and things should go smoothly. And speaking from personal experience, make sure the clutch works right before you put all the engine pieces back in (long story, but it turned out to be a defective clutch).
