Primary Gear Pullers

Re: Primary Gear Pullers (jager)

Just go to a tool rental house. Find one to fit the diameter of the gear and pick the strongest one you can find. I rented one for 10 bucks. Whenever I need it I just rent it. A few years back on the list, I remember a story of a guy loosing a finger tip from a weak puller that failed and exploded when pressure was applied.

Just make sure the puller can handle the load.

Ive got a craftsman three arm from sears thats been good to me. Its was about sixty bucks and if it ever breaks they will replace it. Keep the receipt and pray it doesnt' explode.

Re: (brad black)

A couple years ago, the dealer told me it was going to take a week or two to get one and that if I brought it in to have them do it, they couldn't guarantee that they would not damage the bearing behind it. So I spent about 10 hours in the machine shop at work at the time and made one. It aint gonna break. I'll post a pic when I get home if I'm not feeling lazy.

The Ducati tool I use is solid billet that cups around half the gear, look at the drawing on Ducatis on line parts catalogue. There may have been an old style weaker one but the same one I've been using for the last 8 years has pulled off a few hundred primary gears showing no signs of wear. It helps to tap the end of the puller to pop the gear off. Sounds like there is some operator error and price gouging out there!

Re: (brad black)

I thought I would let the people interested know which puller I got and how it worked. The ducati unit looked like the right tool for the job and really wasn't too expensive. My only problem with getting the ducati tool was that I might need a gear puller to do some modding to the ktm in the future. So I really wanted a universal puller and it would be nice if it was a hydraulic one (but not more $ than the ducati tool...good luck). Well I find this 8 ton hydraulic puller kit. Comes with a few different options, but really only one(2 jaw setup) for the ducati. For 99 bucks I really wasn't expecting much, but I thought I would give it a try (shipping was $30, its heavy ) After a month or so I finally received the puller, it was on back order...my luck. The 2 jaw setup is a little too wide at the top to clamp onto the gear and line up with the shaft perfectly and at first I didn't think it was going to work. But after trying a few different ways of putting it on the gear I got a pretty good match b/w the shaft and the ram. Started cranking the sucker down, with my hand , and the gear came off pretty quickly. Thanks for the tip brad, it would have sucked if the gear went flying through the wall. So to end the story, I'm happy with my purchase...it did it's job and without much fuss.

Re:

After breaking a couple heavy Craftsman/Snap-On type pullers I bought a hydraulic puller that is made in Australia. (Brad, any ideas? I forget the brand) It works really well and comes in handy for other uses. Like someone said, with the puller on damn good and tight give the gear itself a really heavy whack with a brass drift and that usually pops it loose. That seems to be the key. I too leave the nut on, but only about 1/2 turn loose. It will make a definite *CRACK!* noise and the nut will tighten again. Impact it loose again and then you can remove the primary by hand. I'm afraid to loosen the nut a lot because when the gear flies loose it might bugger the threads when it hits the nut (??) Above all, wear safety glasses and heavy welding gloves or the like. I'm not kidding. I go as far as covering everything up in heavy rags. One time when I broke a puller, the piece flew about 75' to the back of the shop and rattled around a couple times. If it hit you in the head it would put a serious hurt on you, maybe even penetrate. If it hit a nearby bike it would cost you a lot of $$!
