TR2/3/3A Wiper motor bushings

[john283]

Hi all,
I have taken my wiper motor apart to clean up and paint. I removed two oval bushings and was wondering if there was an easier way to get them back in other than trying to stretch the holders apart? Thanks in advance.

I've rebuilt dozens of these. The bushes are always serviceable.

I think you may have scrapped this. These were not intended to be removed, I think.

In your position I would try to pull the circular metal springs out of the casting.

As alanjohnturner said "I think you may have scrapped this.", maybe the sad truth, the spring clips are peened in.... I've done some too and found I could reused the old bronze bush. I don't remember seeing anywhere that sells rounded bushings.... I might try drilling out the oval hole to the OD of a sintered bronze sleeve from the hardware store. Force it in and trim it up to the right size. Although somebody here must have something in the junk box if you are totally stuck.

I'd file a bit of the peening away and hope to sneak the clips out. You can re-peen them quite esy I'd think.

Or just pick up a scrap one on ebay. They go here for about 20bucks.

I have about 2 dozen but the transport will kill you.

This guy carries loads of spares and may help you.

I've been where you are before...it may be salvagable...maybe. Get an x-acto with several fresh #11 blades, which are the pointed straight edged blades. Then carefully scrape, or carve may be a better word, the peening away at each peen spot. The aluminum pot metal will carve fairly easily. The clips will eventually come out.

Once the bearings are back in, and the clip back in place, you will have to re-peen them in. The tricky part is you may have to hold the clip under it's spring tension with a deep socket in a vice while peening carefully around in new peen spots, offset from the old peen spots.

It's doable, but will be a bit tricky...

Oh, editting for a final thought I had...

When you pressed the bearings out past the clip fingers, they may have been sprung outward, so the bearing will no longer be held securely. Before re-installing the clips, you had best flatten the fingers back out first so they will hold the bearings tightly. Or, flip the clip over so they are sprung in towards the bearing. Just a thought.

Thank you guys for the help. I removed some of the peen on the large bushing and was able to get a screwdriver under it and it came out. The bushing went back in easily. Encouraged by my success I destroyed the smaller one on the end cap. Now I have another part to look around for. Oh well.

Find someone with a small lathe and make a straight plain bronze bush. Fix it with Loctite.

Wont be quite as good, as the self align facility wont be present, so you may need to use a bit more clearance.

Or make a nylon sleeve and press in the original bush.

John283,

There are differences in the casting of the end plates. Which one got broken? In the picture the parts come from different units. If one of them is a match for your need I'll make you a proposal.... You drop off some canned food at your local shelter or a blanket and I will send you the part.
