Shindaiwa help?

[ArSawMechanic]

I'm working on a Shindaiwa 575, I need to switch the rear handle out with a new one that I got off the bay. I have run into a real puzzle while trying to remove the throttle link rod from the trigger. I don't want to bend up or cut the rod, as I will need it in the new handle, but for the life of me I can't figure out how to get it out of the hole in the trigger. Can anybody familiar with these offer a suggestion?

Can you put up a pic? it has been 20 years since I have worked on one.

Yeah, it looks like most parts are nla, don't damage anything. Tap the hinge pin for the trigger out, it should be tapered and only come out one way.

Here is a blowup of the trigger, etc.

Thank you for your input, Fish! I put some pics up, my problem appears to be the rubber cover on the handle doesn't come off, unless it's like the one that got charred in my garage fire last year. To get to the pin holding the safety trigger, it looks like the rubber has to come off. But the rubber is a solid tube, & is also glued to the metal beneath. The phillips screw by the throttle lock will release the throttle trigger, but that still doesn't give enough play to remove the linkage rod from the trigger.

And, since the replacement handle I acquired is NOS, with the rubber already fully attached to the handle, I am making an assumption that there is some way to get that link rod in there without destroying the rubber. At least that is what I'm hoping!

This might do better for you in the chainsaw forum.

Do you want it moved there?

 

[ArSawMechanic]

Yes, please! Don't know why I put it here...

 

[Mastermind]

Done.

That's a solidly made part! I know when they made that they were squinting. Might give a little squint a try.

I can help.

Sorry to hear about your garage fire. That NOS handle sure is a beauty.

To remove that linkage, simply unscrew the phillips head screw holding the trigger in. Drop the trigger out the bottom of the handle and feed the throttle linkage out with it.

If you need any parts, I may be able to help.

Can you remove the throttle lock and press the trigger a bit farther past go? Or will the trigger and linkage come out as a unit if ya took out the screw?

 

[ArSawMechanic]

The minty handle came with a minty price, believe me! I removed the screw on the other tank, but the safety lock mechanism is managing to keep the trigger in the handle. The spring came out, but not the trigger. Yet. I will definitely do some heavy squinting, & maybe throw some new words at it when I get back to it!!

Unfortunately, the pin holding the throttle lock is under the rubber cover.

Yes, but you shouldn't have to. You can lift the back of the operator presence lever out of the handle while it is pinned in. Use moderate force and be mindful of the tang in the back.

If you don't feel comfortable doing that, you can use a razor blade to slot the rubber on top of the spring pin holding the presence lever in, then drive it out with a punch. Or you can use a leather punch to cut through the rubber covering the spring pin, then drive it out.

Good luck

Every Shindiawa machine I have ever handled has been very solidly built.....

I hope you get it figured out.
