MG TD TF 1500 - pilot bushing woes??

Gents,
My goal this week is to actually get the HiGear 5 speed in the car! It took me 2 days to get the old pilot bushing out (don’t ask why). I got the new bush installed this morning so I decided to use the new clutch centering tool that came with the kit to ensure the first motion shaft of the tranny would fit inside in situ. Now I’m stumped? How far inside the bushing does the shaft actually have to go? At this point only the ¼” tapered end of the shaft will fit according to my caliper! The picture att is my old 4 speed and it’s bushing. You can see it’s an easy fit the whole length of it’s shaft. I can’t just pick up the 5 speed and “give it a try”! It weighs a ton and takes at least a 2 man crew, maybe three.
Do you remember how much shaft went into your pilot bushing? (Please, no crude jokes!) Hopefully only the tip?

Two things, when you fitted the new bush did you use a mandrel, the bush ID can collapse if you did not do so.

If you possess a micrometer or set of verniers measure the diameters of both the centering tool and the new box spigot, they should match. Saves having to trial fit the box which would be a PITA.

Hi Ed,
The Alignment Tool should enter the New Bushing just as you show with your old bushing and shaft. Was the installation of the New Bushing a tight fit? As Graeme mentioned...the bushing could be a little buggered up on the inside if a mandrel was not used. If so...you should be able to dress it up with a wooden dowel and emery cloth if not too bad. The T9 weighs almost 73 lbs.....and a crew of 2 as you mentioned works well....one under the Car and the other in the Interior.

If you got your old one out you should be able to get the new one out to try it on the end of the shaft. I believe I had to have mine reamed slightly to fit.

Hi Graeme,
It's a five minute job to take the bell housing off the Type 9 gear box and you can then try fitting the shaft into the spigot bearing, without the clutch fitted, to check everything is OK. That's the way I lined up the pressure plate. I couldn't afford the comprehensive HiGear kit and fabricated all the bits myself and didn't have an alignment tool. Carry on with the job though it is EELL worth while.

It does have to slip in as far as your old one. Idea- measure the OD of your clutch installation tool and the tranny output shaft spigot. They should be the same. If you are lucky, maybe the tool is too big in diameter? If the same, bushing needs to be reamed, etc. George

Believe it or not, local AutoZone had 2 Ford T9 bushings in stock. ID was perfect. Just a tad big on OD. Machinist is fixing that tomorrow. I bought them both "just in case"!
