GTC Manual Gearbox removal

While it is off I would be tempted to cut across the plate between g/box and engine. That is the plate that covers the bottom of the front of the g/box that hangs down below the bottom of the engine block. The 6/6a with Essex has that bit as a separate half moon shaped bit that can be removed indepe...

Front hub bearing replacement

The spacers have parallel internals with a step down for 5/8" ID outer bearings and so need machining for 3/4" bearings. However, I still have a problem as there's about .005" interference between the start of the taper (Dennis's 0.0235" step)and the clearance for the 3/4" bearing, so I need to ope...

Seat Diaghragms

I found an MGB diaphragm which fitted the frame of my SE6a quite well. Drilling of additional holes in the frame was needed and the clips were replaced. If I remember correctly they came as a kit with the rubber. 20170527_121714_zps5m3buo31.JPG Is it possible/worth amending the topic spelling mista...

6a cutting out

My similar problem turned out to be the capacitor that had degraded. Fortunately I could park within the cones of one of those wonderful motorway repair areas in the outside lane! Cooled down and on my way to reach the next service station and a nice RAC man with a spare. (I should say I was in my 1...

Front hub bearing replacement

Out of interest and to help visualise does anyone know the actual clearance between inside of spacer tube and the taper of the stub? I am still not clear whether the interior of the spacer is tapered? I am aware the inner bearing inner race/spacer tube/outer bearing inner race + shims and nut togeth...

Understanding my automatic choke

Scotbag You need to give some answers to questions asked :) I find it is good to read up about a subject to find out how it works to give best possible chance of fixing a fault. Haynes book on carb's gives good description of the Weber and how it works in detail (library book? also Weber carb site a...

Measured washer pump current at 1.63 Amps continuous running. So with 16W motor taking <5A + 1.63A washer = 6.63A a 10 amp should be ok. (current for glass fuse fast blow should not exceed constant runing value of 75% of fuse rating: 75% of 10A = 7.5 amps) Have put in 10A fuse and run 16W wiper on f...
