Can the cam in a B engine be removed and replaced with out splitting the tractor and inverting the block? Thanks, Tim

I haven't done this one but my guess is that you need to get some dowel rods and drive them into lifters and then hold up with a clothes pin...or something along that line. Lifters will have to held up off cam some how. Some outfit used to sell magnetic ended "tools" that had a skinny rod to reach them down to lifter and a clip affair up top to catch and hold position. Borrowed some when pulled the cam outa my 8070.

Wouldn't the lifters all drop down and fall out when the cam is removed ? Gary

I just went to the shop and rotated my engine on the stand to have a look and I think your only hope would be, as SteveM said, to hold the lifters up with magnets like those rare earth ones that Lee Valley offers? I don't know if they'd be strong enough though.

It says in the manual I have to hold up the tappets and remove cam.... No instructions on holding the tappets. I'm thinking not many more bolts to split tractor after front of motor is removed. That's probably what I'll do if I decide to remove cam. Checked on replacement bushings for the magneto housing today, the small shaft bushing was $40 plus and the gear bushing was $20 plus so I made them from some bronze bearing stock.
