Fly wheel tool

[Dexloy]

I need to pull the fly wheel off my 88' 200hp it has a 1 1/2 in nut on it, having a tuff time finding a socket to fit with a thin wall, also is there a "home made" tool to hold the fly wheel?

Re: Fly wheel tool

Reeldutch, I was wondering about the same tool (holding the flywheel), all I could find at the website above was a flywheel turner. Anybody have any "homemade" ideas on how to keep the flywheel from turning, especially when applying the correct torque to tighten.

Re: Fly wheel tool

the flywheel turner works fine.<br />its not the best tool around but it will get the job done<br />i pulled v4 flywheels with out a problem<br />what you also need is a big breaker barr and get a GOOD flywheel puller set dont get the cheap junk <br /><br />good luck

Re: Fly wheel tool

I can usually get the flywheel nut off and the flywheel pulled relatively easy with a harmonic balancer puller. The problem I have is holding the flywheel in a locked position to tighten up the nut to a torque of 115 - 125 ftlbs (that's a lot of torque and I just can't seem to hold that flywheel still) I've tried wedging metal objects files, screwdrivers etc.. between the teeth and something on the motor and it never seems to hold - either the metal object I'm using breaks or it wiggles free. Any suggestions would be appreciated. I'm not trying to hijack this thread but I think that Dexloy probably is having the same problem. Reeldutch, will the flywheel turner hold the flywheel in a locked position?

Re: Fly wheel tool

Well, I did a search (above), appears that SnapOn makes a flywheel holder tool. However, the easiest way it seems is to use an impact wrench to loosen and tighten the nut and it so happens that I have one!! By the way the torque on my motor is 105 ft lbs ('77 140 hp). Hope this helps Dexloy. I'm just amazed by the wealth of knowledge available on this site!! Thanks to all who contribute!!!

Re: Fly wheel tool

hello<br /> the snapon tool works well. the flywheel is torqued to about 145 ft pounds on the v6 90* looper, double check with your service manual. I also built a flywheel hold with a piece of 3/8 plate steel and a 3 ft handle with a hole bored through it that bolts to the flywheel. I also made a puller like that as well . I did use 1/2 plate to make the puller frame. the nut on that looper is 1 7/16ths. I use a standard 12pt proto socket in 1/2 drive. disregard 87aggie's method of flywhel nut installation. ya got enough problems without making more . they do reccomend a new flywheel nut on installation as well. I always do. its a self locking nylock style net. only designed to lock once. I have used a strap wrench on the big loopers but its not fun. the snap on one works well and is about 69 dollars. sears has one and napa sells one. use grade 8 bolts on the puller and try to find them short enough to keep the puller low on the flywheel. dont run the bolts in so far it hits the trigger. I cant remember if the 200 can do that but some flywheels can. a little tip to save hide.<br /> leave the nut on with about 4 threads. sometimes that looper flywheel can jump when it pops loose. lost some forarm hide once. original puller bolt size is 5/16x24 NF

Re: Fly wheel tool

An impact wrench may be used to loosen but it's not nearly accurate enough for tightening. <br />The evil, backyard hack methods I've used in the past is to jam the starter with an aluminium rod (soft metal anyway) or the old 'fill a cylinder with rope' methods. Problem with the first one is possible damage to the starter. Problem with the second one is that you're putting a lot of force on the con-rod and crank/crankcase, especially if you don't use enough rope. The other problem with that method, as one iboater learned, is that sometimes your rope gets cut off in a port so you have to tear the engine down to retreive it.<br /><br />Nowadays, I use an extra-large strap wrench. When that fails, a flywheel holder/turning tool will be on order.<br /><br />EDIT: Rodbolt posted while I was typing. You would be wise to heed his advice.

Re: Fly wheel tool

hehe ok sounds about right, my strap wrench isn't long nuff so I guess Ill make one and thanks for teh heads up on the nut size I just put a tape on it and guess I wasnt too good at it I'll go back to NAPA and get the 1 7/16

Re: Fly wheel tool

rodbolt, I didn't mean to imply in my previous post that the final tightening torque be applied by use of the impact wrench. You definately need to use a torque wrench to be as accurate as possible. I was just passing along some info that I found in "search". I'll leave the technical answers to the more 'imformed' from now on.

Re: Fly wheel tool

get a flywheel holder turner the one i have bends a little, it will work but as i said there are better ones somewhere.<br /><br />trq it down put your armes close together so you will have more power and push inwards defently use a good torque wrench.
