Jap engine model and cc

I found this and thought it might be helpful for someone. It's a list of JAP (JA Prestwich Industries), was an English engineering company named after founder John Alfred Prestwich) They made both stationary engines and the larger engines were used in the JAP motorcycles (a lot were used in speedway motor cycles), aircraft and Morgan sports cars had the V-Twin. The JAP stationary engine ranged in size from the smallest 34cc two stroke to the much larger type 6 engine, and were used on such things as rotovators, generating sets, milking sets, water pumps, hay elevators and other agricultural machines. They were usually 4-stroke and were usually reliable. They supplied engines to a lot of motor cycle makers and also made parts for some car manufacturers.

Model 0 (34cc) Two Stroke

Model 2A (98cc) Four Stroke

Model 2S (98cc) Four Stroke

Model 4F (186cc) Four Stroke

Model 4/2 (245cc) 2.4bhp @ 2400rpm, Wico Mag A576BZ Four Stroke

Model 4/3 (288cc) 3.5bhp @ 2400rpm, Wico Mag CJ936 Four Stroke

Model 5 (412cc) 4.5bhp @ 2200rpm, Wico Mag CJ936 Four Stroke

Model 6 (588cc) 5.5bhp @ 1800rpm, Wico Mag CJ936 Four Stroke

Model 55 (824cc) (V-twin) 8bhp @ 2000rpm, Wico Mag Four Stroke

JAP was later sold to Norton Villiers

Couple more to add to the list,

JAP MF Water cooled 4 stroke, water cooled version of the 2A



JAP model 3 made in conjunction with ALCO who made the featherweight, overhead valve 4 stroke



JAP D270 which was made in conjunction with Villiers, air cooled high speed diesel.

There is also a water cooled V twin industrial engine.

Thats all I can think of at the mo, well there was a JAP model 3 which which was made after the JAP/Villiers buy out but it was nothing like the orginal JAP model 3.

Thanks for the additonal info Steve. I do like the 2A water cooled, I know I'm strange but just like tank cooled engines no matter of there size.

Quite a unique little engine, one sold on ebay a year or 2 ago for about £250 I think, not very many about!

Cheers Steve

Not a bad price when they are (dare I say it ) rare. I've never come across one so going to have a look into them see what I can turn up.

Stu

They also did a 5hp water cooled 2 stoke made for the Seabea Model 5 outboard, I think this engine was also used to gensets?

Cheers Steve

That water cooled is a nice little engine, I havent seen one of them.

Thanks for shairing with us steve.

Just had a chance of a MF, but at £325 I had to leave it, not my kind of price with another baby on the way!, I think its going to appear on ebay sometime soon.

Just for refrence, the JAP V twin was a 750cc avaliable in air or water cooled, the air cooled engines were fitted to Lister Autotrucks, where as the water cooled engine were used as part of Dennis fire pumps, a singe cylinder version was also made.





Also had a chance at one of these but again at £400 I had to leave it

Cheers Steve

Congrats Steve and his wife for the announcement of the birth of your forthcoming arrival.

I never knew Jap made anything as large (cc) so thanks for letting me know, I thought the biggest was 500cc.

Stu.

Well there was a 1000cc engine fitted to Morgan 3 wheelers.

Cheers Steve[list][*]

I forgot about the Morgan having the V-twin on the front of there 3 wheelers. My memory is deffo on the way out, I blame all the drugs I take
