Sears Mini...

#1
This is my next project. Given by a friend who's son ran the engine out of oil. Broke rod..It is the one with springs. pivot point..and jackshaft..(?)..Therein lies my question..The clutch..and I'm assuming it came off the original engine.. has 2 12 tooth sprockets..and 2 chains..BUT..the jackshaft has only ONE sprocket. Is the shaft damaged..or do I have a clutch from something else..I will use a 4-5 HP Briggs.Also..does the scrubber brake..(the only one on the bike) use some sort of lining on the steel ?..thanks..JV..ANY help or advise on this bike will be most appreciated. I just finished a Wards 325 for one grandson. This is for another..

Sounds like it has a 2 speed jackshaft.Got any pics?I have a Sears but its the Bird duck style
rigid frame.Look in the pictures section,there are some like you described there.

It was apart when I got it..The engine is trashed..and it was in a box. The clutch has 2 sprockets..the shaft..just one. I'm new to mini's..How would a 2 speed work ?....I'm thinking of eliminating the jackshaft..and using a conventional left side sprocket..

Ive never dealt with a 2 speed just know clutch has 2 sprockets.And the later version Sears came with the 2 speed shaft.If the engine will work i say do it.Is the brake pad steel or aluminum,they rub right on the tire.A 5 hp briggs fits i believe and should work well.


Looks like your new here welcome,theres plenty of good help here!!!

Have to buy an engine anyway..Brake pad is steel. Was there a lining of some sort ?..Still baffles me why clutch has 2 sprockets and chains..and only one on the jackshaft. Would it be better to switch to conventional left side drive ?..There is no hand operated brake..

It probably came with the 2 speed if it has sprung forks. They use the double sprocket clutch. Do a search on here for 2 speed and two speed. The tank gets in the way if you use a 5hp Briggs. They came with a 5hp Tecumseh with a front tank, then later used the backward looking tank on the frame. Here is a pic of a rusty 2 speed.
