I'm disassembling my inertia starter for inspection and cleaning.  The Shop Manual instruction for removal of the pinion assembly from the armature shaft is a bit vague.  Would someone kindly provide a detailed description for the removal procedure?

You need a Bendix Spring Compression Tool

 

The tool is basically two plates, very thick metal, two threaded bolts and nuts.The lower plate has a cut out to go around the shaft.
Tighten up, to release the pressure, remove circlip (item 7 on the end) through the hole in the top plate and loosen equally, both sides.

 

You can make one here is what they look like http://www.ebay.co.u...=item2597ca3dd2

Corey, I made my own tool for the task like Dave suggested.  You can use 1/4" thick steel from the home center to make a squared off copy of the tool shown in the link Dave posted.

Thanks gents.  I'll fabricate the tool.  I trust that disassembly is self-evident once the spring is compressed.

Dave, can you tell me what size bolts you used?

Thx.

[newenglandmini]

Dave, upon further reflection, would it be possible to provide the various dimensions of your version of the tool?

Thx.

When reassembling don't use any oil! Wash the parts in paraffin NOT petrol (petrol contains upper cylinder lubrication which will leave a residue) . Any oily residue will attract dust and clog the bendix or at least slow the throw enough to stop it working properly.
EDIT. I have heard of powdered graphite being recommended for lubrication, but if everything is clean and smooth then it's not necessary !

As above, clean and dry the parts and if you want, use powdered graphite or Moly Disulfide powder to lube the sliding parts and spline the Bendix moves on.

 

Corey, I'll look for the tool I made and post back later today or tomorrow.  I don't remember using anything super heavy duty.  I believe all I did was take some flat stock and make "U" cuts in them to support the spring.  I either used 5/16-24 or 3/8-24 hex head bolts.  How to use the tool will be obvious when you look at what is there.  You need to compress the spring to expose the circlip tucked down inside a bit on the end of the shaft.  Pry the clip out and slowly loosen the tool's bolts to relax the spring.

Yes 5/16 bolts in mine

They come up on ebay. I paid about £5 for mine :)

Doug, no need for any more info.  I already made the tool and disassembled the starter.  I think I inadvertently improved the design.  My tool also functions as a fixture to steady the starter whilst compressing the spring.

 

I was unaware of the lubrication issues.  I've always used lithium grease to lube starters after refurbishing them, and never encountered any subsequent starter problems.  I did note that this starter was dry when I disassembled it.  I'll follow your advice and use a dry lubricant when I reassemble the starter.

 

I note that Minispares does not offer replacement bushings for the starter.  Is there a source for these?

 

Thanks again to all for your assistance.
