Good evening there 320 fans,
First a special shout out and hearty thanks to John and Glen at Northtown Transmission and Bob down at Victoria British!!! Thank guys!
Hopefully this will be the last we talk about the transmission...maybe, but probably not. So I spent quite a bit of time with Bob at Victoria British working to determine a compatible set up. After about 30 minutes and pulling the parts from 5 different MoWoG transmission we found a suitable match. The clutch disc and pressure plate that works is from the 1098cc AH Sprite, that's the Mk II and III. The MGA/early B was too large at 200mm as pictured below-
The release bearing or throwout bearing is from the 3 main bearing MGA and early MGB. Pretty sure the only difference in the Sprite and MGA/early B bearing are the clips that keep the bearing from falling out of the fork, but do not quote me on that.
Sooooo, starting at the flywheel and working our way back to transmission input shaft seal here's all the parts, part numbers, and manufacturers-
VB 4-006 3-in-1 Clutch Kit ($219.99), includes pressure plate, throwout bearing and clutch disc for the 63-66 AH Sprite w/1098cc. Sorry you will have to go the package as the disc is not sold separately. But if you look else where 63-66 AH Sprite w/1098 cc engine is the set up that will work. Again I do not know if this bearing will work, pretty sure it will though.
VB 4-322 ($14.95) this is the release/throwout bearing from a 55-62 MGA
VB 9-1018 ($3.95) Clutch lever boot - common to many British sports cars
VB 1-7411 ($1.45) Transmission Front Cover gasket
Timken 471466 (~$4.78 ea) Reverse and Forward cross shaft seals, you will need to order 2. Sorry you will have to re-use or improvise as I could not find a suitable felt gasket.
VB 1-7001 ($1.95) Transmission Side Gasket
VB 0-109 ($2.95) for a transmission drain plug, no magnet, black anodized steel allen head plug.
National 710324 (~$9.78) is the rear output shaft
Pretty sure that's all the parts you will need, let me know if something is missing.
Okay, so over the weekend we came close to getting the transmission back in, but did not make it. So here's what we did accomplish-
-Replace the engine back plate and flywheel
-Replaced the rear output shaft seal
-Removed and sealed up the cross-shaft cap cover nuts on the passenger side
-Place transmission in neutral and replace the gate assembly and the forward cross-shaft as one unit. Re-insert the reverse cross-shaft, and seal up the access cover. This top pic shows the transmission in Neutral. You will need a big screw driver to align the fork so the lever, operating change speed goes from front fork to the back fork in single motion, no going left or right.
-Replace both forward and reverse cross-shaft seals on the access cover
Well that's about it. What you did not read or see is all of the cleaning, scrubbing, an almost final wipe down only to see more oil and dirt that need to be cleaned up, followed by one final wipe down with denatured alcohol before painting. This quite a bit of work that consumed much of our time.
Tomorrow we will finish up the transmission by with one last touch up paint job, install the clutch fork, throwout bearing/release bearing, the boot and dust cover. I'll post some before and after pictures. Once this is complete we will still need to install the pressure plate and clutch disc to the flywheel. And then before we install the transmission make one last inspection of everything we touched, replaced, or sealed up for one final QA/QC.
Well that's a wrap for tonight. And as always here's the link to more pictures -
