How can you tell the difference between series 1 - series 2?

series one and 2 are both old shape engines so have a 108mm drum. the series 1 has a different shjape engine number plate. (where the numbers are stamped its different basicly) the new shape engines have a nut on the outside of the case with a floating imput shaft. they came in 200mm drum and disk. you can get wc in series 2 old shape and new shape but they didnt do any wc engines back when the series one was made.

hope this helps

 

the engine number on all piggys (prittymuch) is a small rectangle at the back of the engine, the setries 1 125 engine had an iregular plate (like the dna 50 engine) its bigger and just looks like a big flat part of the casing rather than a thicker casting. easily tell the difference when you see one as they just dont look right.

 

now how good am i for spotting that (did anyone actually know about these engines?) just remember replacment cranks are impossible to find. so be prepared to replace the entire engine or mod the entire case for a stock size crank

 

wind it by hand untill it pulls the clutch all the way forward (shaft wont come any further out) then hit it a couple times with an impact wrench. around 30nm is fine but too tight an the bearing will be crushed an wear out verry quickly

 

the series 3 (its actually a new shape engine with the nut on the outside of the case as the series 1 and 2 are old shape an the series 3 is just called a new shape) but ye there the best as the gearbox bearings/supports arnt part of the engine casing. just the gear plate an tranny cover. also theuy can be used for disk and ether ac or wc..

 

old shape small drum (108mm) series 1 and 2 dont have one. theres 2 nuts behind the wheel.. bottom to drain, fill it till it comes out the top one.
