Pulling the flywheel process

Post by MN John Deere sledder »

Well, I work a little on this sled every day, Yesterday I got a roll of that 120 grit emery cloth and today I got myself a puller like I was told in an earlyer post. Eather im doing somehting wrong or this is a very stubborn machine. One of the pictures shows the vice grips holding the outher side of the engine so the whole thing wont turn, One of the pictues shows how I got the puller set up. and the last photo is that side shot which is suppose to show that slight bend in the flywheel where I had one of my puller arms attached. I get that puller so tight on there and beat like hell with my hammer and nothing happends. What do you guys think?

Pulling the flywheel process

Post by Rodimus Prime »

number one WRONG puller.. you want a universal puller looks same as steering wheel puller. number two is using a piece of small rope you jam the cylinder to keep engine from moving.. using a screwdriver to find piston top dead center you want to turn engine so that its just before top dead center(piston at higest point) just put in rope till you cant jam anymore in and the piston with rest on rope . Note be sure to that piston is JUST before tdc and NO ports are open otherwise you can ruin the rings.

if you must use that puller you can put the arms inside those small openings on flywheel tighten as much as you can ( you may need to extend ratched with pipe. if it soes not pop off at that point use a LARGE hammer at give the puller bolt ONE very good whack.

oh and before you ask you have the wrong clutch on your sled it should be a 100 or 101 comet clutch.

You will want to use a steering wheel style puller on the flywheel, not the jaw style you have on there now. The three small threaded holes in the flywheel, by the center hub is where you will insert the metric bolts, I believe 6mm. Pulling from the center will not distort or damage your flywheel.

JD Matts quote from the FAQ section:
Removing the flywheel:
This requires a steering wheel puller. Three bolts thread into the flywheel, while a center bolt pushes against the end of the crankshaft. This puller can be purchased from almost any automotive store, but you might have to purchase the correct bolts to work with the flywheel separately.

I bent up several ring gears in my younger days trying to remove flywheels like that.

PS, whats up with the vise-grip on the primary bolt? Get yourself some wrenches and sockets. You'll tear up alot of heads using vise-grips.

Just for the record, I've had good luck with the 3 arm pullers (thats a two arm puller in the picture right?). Tighten, then tap, tighten, tap, tighten the WHAP (one good strong wack witha 3 pound hammer and they have alwasy come off.

BTW... I did not know about the rope trick (thanks)

I use a harmonic balancer puller I got from AutoZone. You can borrow tools from Autozone. The way it works is you pay for the tool upfront (I think my puller was $14) and then you can bring it back and they'll give you your money back, or keep it and forfeit the money. Go in and ask about borrowing tools and they'll give you a catalog to look through. I ended up keeping mine because it was so useful. The bolts that come with it may work - otherwise you'll have to use your own. Try to find some really hard ones at a hardware store. It's also best to have an impact wrench to tighten the puller, but I did it once with just a regular wrench. If possible, soak it for a few days to a few weeks. Just go out every now and then and hit it with WD-40 or PB Plaster or something. And keep on wacking the puller bolt with a heavy hammer.

If all else fails, try a torch. But ONLY if all else fails and you absolutely cannot get it off.

Oh, and one other tip. Once I get the puller mounted, I wedge a wrench or whatever I can find in between the puller and some other hard part on the body to keep it from turning. Holding it on the clutch side like you're doing may lead to a twisted crank.
