Anybody out there have an anser on repairing the ring gear on a 1600 fly wheel as it is not a replacable item I have thought about grinding the burrs of and building it up with amig welder I am an old boily so welding wont be a problem any other suggestions would be appreaciated thanks Big Al

What you are suggesting used to be a commonplace operation in the days before everyone could afford to replace anything that was suspect. Not just, or particularly, Landrovers, but any vehicles. Where the bottom of the clutch housing was removable, it was often done in place.

Sounds good to me. The weld material needs to be good stuff as ring gears are hardened. Restore the involute gear tooth form with a die grinder and tungsten carbide burrs.

Another trick is an old used car dealer one. Press the damaged ring gear off the flywheel and turn it around forty-five degrees in the case of a four cylinder and press back on. In your case you would have to re-drill the bolt holes to the crankshaft a similar amount. This gives the starter gear an undamaged section of teeth to start with and momentum usually carries the damaged section past the starter gear when cranking.

Also you would have to be a bit clever to transfer the timing marks
Not thay easy.............

Timing marks are on the flywheel, not the ring gear, unless I am mistaken.

If the 1.6 is a integral one piece ring gear flywheel same as i said........

[groucho]

The 1.6 flywheel part No 212381. It also shows a seperate part No for a ring gear No 232404. 48 to 53 1954 and 55 to 58 al show different part No's
I have somewhere a write up on replacing the ring gear on the early flywheels. ie machining of the old one and shrinking on a replacement.
I will try to find it. The ring gear is soft as you can split them with a chisel
so building them up probably would work............

The ring gear is actually hard, hence it will split (crack) fairly easily.

My understanding is that the problem is not that the ring gear is not a separate part, but that the part is not available!

I will have a look today to see the difference between the 1.6, siamese, and 2 litre flywheels. Yes they are heat treated bit not that hard i have sawed them with a hacksaw. After heating them it don't do the heat treatment any favors. They are hardened at the top and softer at the bottom.
You only have to look at how they wear. It shows in the parts book a seperate ring gear for the 48/53 series so they may have well made one or a printing error in the parts book........

A standard one piece 1.6 flywheel

1.6 flywheel with replaced ring gear
they machined the timing marks off for what reason i don't know

1.6 flywheel with later ring gear fitted

You can replace the early flywheel
with early starter



https://www.aulro.com/afvb/images/imported/2010/03/1270.jpg

[groucho]

to late flywheel with late starter
You have to changs the flywheel housing
from 3 bolt to 2 bolt. common mod........

Have since cleaned it up with a grinder and asmall thin disc looks alot better will set it up minus g/box and run it thanks for your help big AL

i would hunt around for another flywheel.. they are not rare or uncommon things
