Norlett 5000

Hi all,
 
I am new on here, so please forgive me if this have been covered before. For many years there has been an old Norlett rotavator left in my shed from the former house owners. I have identified it as a 5000 and have for the last few weeks been making an effort to get it running. I’ve done so and in the process completely rebuilt the carb, fitted electronic an ignition conversion, new breather pipes exhaust. It’s running lovely now.
However, there is an oil leak from the bottom of the drive system, where the tyne shaft comes from the housing. I’ve found a PDF manual on here and going to look dropping the whole gear assembly, does anyone know if the oil seals are commercial available?
My next questions are around the accessories, I’ve had a good look in the shed and found a few bit that go with it, namely some additional tynes, a dozer blade, what looks like some kind of edging disc which slips on the side of the tynes, a plough and set of towed tynes.
My questions are, does anyone know if any of the modern rotavators have similar 30mm drive shaft and therefor enable me to use these wheels on my old Norlett to tow the plough and cultivator tynes?
Also, the front dozer mount seems to be missing, does anyone what this looks like so I can make one, or better still buy somewhere?
Many thanks.

Hi All,

I am new to the forum and look forward to contributing if I can.  I am a keen gardener and have kept an allotment for 30+ years and am still learning!

I have a 3hp Norlett and a Norlett 5000 two speed.  The 3hp has been fantastic over thirty years but has now started to leak like a sieve through the tine shaft oil bearings.   Is anyone able to tell me the size of oil seal required so that I can order in advance?  The weather is just right for working the soil and I would like to keep the downtime to a minimum.  Any help gratefully received.

If you've got one, get the seals out, measure them (outside diameter, thickness, and the actual the shaft diameter, then look them up on a bearing supplier's website. You might actually find the dimensions on the seals themselves! They will be standard sizes, probably imperial at a guess.

Recently took mine apart. They are:
Inside diameter     30 mm
Outside Diameter  42 mm
Width                     7.3 mm
with a spring on both lips.

Fairway seals Home - Fairway Seals are sending me a couple of 30 x 42 x 7, £6 each. When I fit them I'll let you know how good they are.
