Clutch Rusted on Cannot Get off...sniff!

[arcticcow]

On my doodlebug, the clutch was whinning and screeching and actually shut the engine down. (its a new purchase from craigslist). I got my gear puller and off came part of the clutch, but the cogged sleeve is stuck on the shaft. I cleaned what came off and put it back on, hoping the cleaning would take care of the loud noise. What I now realize is that the cogs are separating during use and this causes the loud screech.

My question is, how do I take off the cogged sleeve that is stuck on the crankshaft? My gear puller cannot get into the limited space enough to get any purchase on the dealie-bob.

Should I cut it off? WD-40 it for a year or so?:doah:

Pb blaster is good for rust and your clutch bushing need a drop or two of 30wt engine oil!

I'll try the Pb Blaster, but I'm thinking it may need to be cut off..which will be a tedious and delicate job to do.

I used an angle grinder. Sucked. Using the key slot as a guide helps eliminate "some" of the gouges.

Make sure there isn't a set screw in there. Spray some Aero Kroil or whatever you have on there and give the oil time to penetrate this should help to remove the rusted part. Then try to leverage the part out of there being careful not to damage the crankcase.

Thanks everyone for the advice. I'll share my experience once I get the part off!

All good advise but mine is , scrap it and get a new Predator while they're $99 !:laugh:

I like heat for removing rusted parts. And a BFH.

I've had good luck with a 3 jaw puller, can get them fairly cheap and they come in pretty handle for all sorts of stuff.

I'm leery about putting a 5hp on a doodlebug. I'm no wheely champ. I did manage to buy a harbor freight engine in Abq Craigslist..$70 buck ...couldn't pass it up.:laugh:

 

[arcticcow]

I will try this. I have a heat gun and its gets pretty hot. I'll hit it with the penetrating oil and see what can be done! Thanks for the tip.:2guns:

 

[arcticcow]

Thanks for this tip. I just might be ablel to locate something I can make into a gear puller!:happybday:

I finally got the clutch off. I used a file to score a line on the clutch down to the shaft. I also used a drill to put perpendicular holes into the clutch metal and this helped a lot by weakening the area I was filing. It was a very tough and time consuming job.

 

[buckeye]

That is patience right there if you filed that thing off. Holy crap!

Nice to see you got the rest of the clutch off :thumbsup: Now you just need to get a 16mm clutch DB30R-142 Baja OEM Clutch 11T 97cc 2.8hp 16MM how well does that little engine run :shrug:

 

[trinik7597]

that is more like a prison brake than a clutch removal :laugh::thumbsup:

 

[manchester1]
