Question: Skilsaw Model 77, Worm Gears!

KLS

Has anyone tried substituting type 17 worm gears in a type 16 skilsaw? I have a model 77 '50th anniversary issue' worm drive and the gears are shot. Apparently the type 16 gears are no longer available, but since these saws didn't change much over time, I'm hoping the newer ones fit. Anyone?

Kent

Hi Kent,
In answer to your question. The type 16 and type 17 gears are both different sizes and the housings are not the same. You might try some local repair centers to see if they have any of the older gears.

Question: Replacing Skil 77 Armature

Steven

I am replacing a bad armature on a Skil Mag HD77 worm drive saw. What else should I replace in addition to the armature assembly? Are there any special tricks?

Question: Brushes

robert

My wormdrive was sparking a lot on the back, replaced the brushes and is still sparking a bit more than normal. What else could it be?

Reply: Brushes

Mark

Hi Robert,

The sparking you are seeing through the rear vent holes on the saw is caused by a bad armature. Many different things can cause the armature to go bad but the most common causes are using too long of an extension cord that is too small gauge or cutting in a manner that causes the saw to pull more amps than it can handle. (Such as deep cuts in concrete, etc.) The armature will need to be replaced.

There may have also been damage to the field. When you open the saw you will want to look for signs of burn or melted insulation on the armature and field. The field can also be tested with a multimeter set to test impedance (ohms). To test the field take an impedance reading from one side of the coil and then the other. The number you read from each side should be within a few ohms of the same. If it isn't the field is bad.

The armature is part #2610931892 and the field is part #1619P02674. Both of these parts are available from http://ereplacementparts.com.

Good luck with your repair!

Most likely the armature. It's about $60. Look for a little black spot on one of the commutator bars or connections, all it takes is one and the whole thing is no good.

Question: Skilsaw Model 77

azshadeguy

I am looking for some parts on a skilsaw. I can't seem to find the right model number on the parts page. The model number is a 77 not the HD77. serial #1B504000. This is an older saw. What I am wondering is if the the parts are the same? What model number is the closest?
Thanks Paul

Skil sells gear oil for your saw. Can pick it up at most tool repair shops or Home Depot.

Question: Worm Gear Compatibility?

KLS

I have a Skilsaw Model 77, type 16 (in fact it's the '50th anniversary issue'. I need to replace the worm gears. Are they available? Can I use the ones listed for the model 17?

Thanks for your help!

Kent

Reply: Worm Gear Compatibility?

WJA

Hello KLS,

The gears for the type 16 and type 17 are different and not interchangeable. Unfortunately the manufacture has discontinued the parts for the type 16. So either find a type 16 with good gears or time to purchase a new one.
