While the crank lip seal is the same size, I recall that there are 2 types of rear lip seal carriers. 730E 6335A, from 67 - 73 is the early type which uses a cork pan seal. The later type of rear carrier, 681F 6335 A-A, 73 on, uses a wider rubber pan seal.

Hi

Must be perfect in center:

Hi,
This post may help

That's good info and makes maybe a more modern aproach with a nitrile/rubber seal.
For the crank Lip Seal the only thing i can see different is Red or Black+ a very big difference in price

One more tid bit. Check that the spring inside the lip seal is "screwed" together. If not you will get a leak!

Yes, as said in Miles Wilkin's book "LOTUS Twin-Cam Engine" page 130

By the looks of things there is a strong possibility that the Ford KA rear seal might fit. The Valencia/Endura-E engine is a cousin of the Kent engine but crank bearing sizes, bore sizes, etc. are all different. I know the timing chain is the same as the Kent even though it's under a different part number but not sure about anything else.

Think I might head down to a Ford dealer to see if they have one. The Endura-E engine has only been obsolete for around 12 years versus 36 years for the crossflow so hopefully won't get any laughs when I ask !!

Just got the Flywheel back from skimming and a nice job was done.
I've ordered a new Starter Ring so things will be 100%.

New ring Gear fitted but not so easy. I didn't see that the old ring gear which was the original had deformed the Flywheel. This had increased the location dia a small amount on the unused part.
I would suggest that when replacing the ring gear that the unused part is chamfered to give a lead in location for the ring gear (at 300?C?).
I put the Ring Gear in the Oven 280? maximum and the Flywheel in the Chest Freezer.
I still had to use a drift and a big hammer to locate the Ring gear

Not much help now but others may not be aware, there are two sizes of 110 tooth ring gears both for inertia starter, a 10.048 and a 10.167 inch.
I have had a ring gear come off in the past so this time I had it tacked brazed in 3 spots, who designed a fitment were the starter action is to pull the gear off!!

+1 100% correct. The Starter tries to pull the Ring gear off the Flywheel and not against the location shoulder.
Not at all logic but for the modern starters maybe it's good , designing for the future evolution
