My Speedex has a 16HP Vanguard twin with electric start only.

 

I was having trouble with the starter clutch only engaging about 80% of the time.  I'd have to try several times to get it to grab.  A year ago I replaced the clutch assembly.  It was fine until it got cold, now sometimes it won't engage.

 

I'm going to be tearing into the tractor today for maintenance.  I'm tempted to apply silicone lubricant to the mechanism to help it throw out.

 

Any thoughts on whether that would be a good/bad idea?

Are you talking the Bendix?
Very lite oil and pretty thin stuff.
Silicone would be good for a while, but make sure you clean off the thicker stuff that is slowing the mechanism down.

My experience with silicone is that it 'disappears' or something
Be lubed up and fine, then suddenly the squeak is back and no lubricant.

Things may have changed since I was told this. No lubricants on the bendix or shaft. The reason being that it attracts dirt and gets stiff in the cold. I tried graphite thinking it was a dry lubricant but that didn't work either. Keep it spotless and it should work. Having a rear main seal that leaks will also cause starter problems.

Try dry powdered graphite lubricant.  Slick , but does not collect dust/dirt.

Clean the Bendix but no lube, it will attract dirt. Clean all electrical connections, especially battery terminals, solenoid terminals, starter terminal and ground. Make sure battery is fully charged. It is time of the year when batteries die from cold. It has happened to me several times where the starter bendix failure was an indecation that the starter or battery was about to die. The starter wasn't able to spin fast enough to make the bendix engage. Good Luck, Rick

The no lube would make it wear a little faster, but solve both problems.
I learned something today... or relearned something I've forgotten :D

I'd read that about the battery/electrical.  The starter seems to spin up quickly but who knows.......

My Speedex always binds at the compression cycle, even in warm. Goes OK in summer, not so god now. It kinda "Lumps" over and only can do a few times. If no start right away, needs battery boost. All good and bigger wires on system. Is that weak motor then?

Where are you connecting the booster? If you were can I think its the battery and it makes a difference, your battery is weak.
