Hi all...can anyone give some information regarding the starter arm on 56 172..My arm is wobbling quite a bit where it is mounted to the starter. I have looked in my parts book but they don't break it down enough..thanks Pete

The "arm" ... or lever... which is operated by the pull-cable... is indeed a bit on the "wobbly" side when normal. As long as the mounting shoulder-bolt which holds it to the starter is bottomed out and the lever contacts both the start switch button and the pinion gear plunger properly, don't be too worried about it. I'll locate/post the link to the measurements for those adjustments (also found in the TCM overhaul manual as well as in this site.)

In the TCM Overhaul manual, the instructions for adjusting the starter shift lever (and therefore the pull cable) are given in Section 17, pg 52..

"Adjustment of Starter Shift Lever
It is very important that the cable or wire control return spring should have sufficient tensions to bring lever to fully released position when control is released. It is also necessary that there be 1/16 inch minimum clearance between clutch shaft end and starter shift lever when control is released. There is 9/16 in. of travel at the starter gear pinion. It is very important that the starter lever compresses the starter pinion gear 7/16 in. of this travel before contacting the starter switch, the remaining 1/8 in. of travel will be used in making the electric contact of the starter switch."

Here is another source of this adjustment, provided by the Niagara folks who sell the starter clutch (see last page of the doc):

Thanks so much for the reply. I have a friend with the same aircraft his arm is much tighter than mine...mine moves so much that it almost misaligns with hitting the shaft when you pull the cable. I am assuming there is some worn bushing between the arm and the bolt mounting to the starter..any ideas for a part number or exploded view would be helpful..thanks again

[GAHorn]

If the hole in your lever/arm is worn ... or if your shoulder bolt is worn... to the point of your concern... then perhaps you should consider replacing them or re-bushing them.
It might be simpler than you think. A flat washer beneath or above the lever might be all that's req'd.

Thanks will take another look, I figured it was a bushing, just was looking for the correct part number...thanks again

The arm is aluminum with a hole I.D. of .372". The shoulder bolt has has an O.D. of .371". Looks like there is enough material on the arm to drill it for a bushing.

thanks everyone...I ordered a new arm and bolt...35.00 not bad..

More like amazing!

The arm on mine was a steel stamping. I bored the hole out to a larger size, brazed the hole closed, dressed the outside smooth, and re-bored and reamed the hole to the size of the bolt.

Can't recall if it was because of this thread or not, but I found that the arm and bolt on my starter moved considerably. I first noticed that I could not unscrew the bolt as one normally would, i.e. I had to twist and pull rather than just twist counterclockwise. Once it was removed, I noted that the threads on the bolt seem to be rolled over, probably from wobbling side to side in the hole. Couple questions:

Where were these parts ordered from? My arm seems to be okay, but the bolt definitely not.

Looking at the photo of the new parts in this thread, seems like the length of mine is about right. I was concerned due to the texture on the end that mine had sheared off inside. I'm guessing the threads in the case are ok, but if not, can the hole be enlarged and helicoiled?

May be an excuse to convert to the lightweight starter?

[blueldr]

Strangely enough, my old engine had a steel arm on the starter. It wobbled more than I cared for so I brazed the hole closed, re-drilled the hole, and file dressed the outer surfaces to fit the shoulder bolt.

I'd bet a salvage company could sell you those parts cheap.

Even if you had to make a complete exchange of your starter for an overhauled one (from Aerotech of Louisville, one of our supporters and a presenter at the last convention in KY) ... it would be waaaay cheaper (and better in my opinion from the standpoint of cutting up parts inside your engine in-situ) than a conversion to one of the "lightweight starters".
