Emery 350 Universal

[andyfrost]

Just back home after a long trip away , but it seems well worth it , I’ve hit my Holy Grail ,an Emery 350 Universal rotavator , first looks it seems very original with all the correct parts as far as I can tell. Would any readers have any manuals or parts diagrams , or indeed any info on them however small. One or two issues , engine is rather tight through standing , and the usual no spark , nothing that can’t be done , severe wear in rotor shaft , I’m guessing worn bushes or shot bearings , which will be my first point of attack.

There are some photos and a old advert in the vhgmc photo gallery.

Andy I have an Emery like this one but only have a copy of the advert as shown in gallery. If your is the same it would be good to know what spark plug it has as I am unable to read what is on mine.

Morning Charlie , no mine is different to yours , it has what I think is a JAP 350 sidevalve engine , it’s definately JAP , crankcase is stamped , and JAP embossed in the cast alloy cowling. It looks exactly the same engine as one fitted to one of the early Atco mowers , which had Atco-JAP embossed in the cowling.
I haven’t looked close enough yet to see if it’s actually a dry sump engine , as the oil appears to be in a resevoir built into the bottom of the crankcase , whereas yours has a seperate oil tank.
As for spark plugs , mine has an 18mm , I seem to recall that you said yours had a 22mm plug , Fordson N and E27N tractors had 22mm , so it may be worth you getting in touch with some vintage tractor boys.
It’s pouring with rain here today , so it will be a workshop day today , I’ll hopefully start work on the Emery.

A couple of days in the workshop on the Emery , valves re-faced and re-seated , bore honed and cleaned , it now turns over quite nicely. Magneto sorted , nice blue spark , just waiting delivery on one or two very minor parts , and I see no reason why the engine shouldn’t be up and running quite soon
As for the worn rotor shaft issue , Emery’s engineering takes a bit of a dive , the rotor drive case is a sealed/welded unit , and doesn’t come apart , I’m only guessing that back in the day they offered service/exchange or even just brand new units . I looked at the chains and primary gearing , there is no bronze evident , so in went some 00 grade grease , after it settled a small leak was evident , but nothing severe enough to bother me.
Work in progress as they say , but all being well I hope to bring it to Weeley this year.
