chappo Posted July 12, 2018 Report Share Posted July 12, 2018 Hi guys, Please see images of my Cub casings.Just split the engine. The first casing shows an area milled out and a plate inserted with four Allen screws inserted. Is this the mod to allow access to the oil pump. You lads who know there stuff will probably recognise the model of engine but it’s a 1961 year model. The second casing, well, I’ll wait for some ideas, is it to allow the gearbox sprocket to be removed without having to break the motor. It’s a really poor fit. Thanks.

naichuff Posted July 12, 2018 Report Share Posted July 12, 2018 The clutch mod is quite common I have two engines done this way Yes you can change the sprocket with out splitting the cases It is the first time I have seen the oil pump mod done though Quote Link to comment Share on other sites More sharing options...
section swept Posted July 12, 2018 Report Share Posted July 12, 2018 Someone has invested a lot of time and energy here to make the Cub engine more repairable. There appears to be a drive chain clearance issue pic 2. What is the rest of the bike like? Quote Link to comment Share on other sites More sharing options...

If you look on this forum under my original post, ‘ Well I collected the Cub today ‘, there are a few images of the bike. Quote Link to comment Share on other sites More sharing options...

chappo Posted July 13, 2018 Author Report Share Posted July 13, 2018 I’ll try and reload one or two. One as is, one as was 12 years ago. Quote Link to comment Share on other sites More sharing options...
