brucey Posted February 10, 2019 Report Share Posted February 10, 2019 (edited) Depends upon how late you crank cases are. The chances are yes if you are replacing an older type pump. Chris at Meriden off road can advise either way as he does a conversion kit and can also machine the case if required. Photo shows later pump fitted. Web on left of pump has to be machined to clear pump slider blocks. You also need a longer drive spindle to run the later type pump. These all add up! I also just put an upgraded Morgo standard pump in one of my Cubs which has worked fine for the past 10 years. Hope this helps.

Look at the weight savings man! I can see lettering on one hex bolt. Allen heads not tapered. And purely for visuals, replace all those ugly cross heads with button heads or c'sunk allens. Apart from that - lovely. 1 Quote Link to comment Share on other sites More sharing options...
