1275 engine swap- HELP!!!!

[honda90]

When I fitted my A+ in my series II the original starter which was fitted to the 1098 caught the flywheel when the engine was started. I swaped the 1098 starter with the one from the marina it was then fine. Must be a slight difference in the length of the motor shaft though they did both looked the same to look at.

bmecosse & everyone

the dia. of my backplate is 10 mm.

so you think shortening the spring on the Bendix wwould be a better option.how difficult isthat do you think?

It sounds as tho' it is a case of some do some don't. Steve at ESM said if it is a used starter ie. teeth worn there seems to be less of a problem. mine is a brand new starer.

I'll have a look at this later - just my feeling is the spring could be shortened slightly without any ill effect - it's there to 'catch' the bendix when it's thrown out by the flywheel as the engine starts. But may be small shortening of the teeth on the bendix won't do any harm either - could be easier to do. Do you not have an 'old' starter you can try ?

[MarkyB]

How much is it catching by?
You need a special tool (I think) to dismantle the bendix as the spring is under tension.
Then you can bring the angle grinder into play .

Home made tool is easy enough to make !

[MarkyB]

Depends on what facilities you have to hand.
Ebay has come up trumps, and even gives an idea of what such a tool looks like:http://cgi.ebay.co.uk/starter-motor-ben ... 1|294%3A50
I'd buy it now as I bought mine donkeys years ago before pre engaged starters became de rigeur.

[bmcecosse]

Yes -that's the thing -at that price it's not worth making one !

I assembled a starter to my 1275 Marina engine - with 1098 backplate and 1098 flywheel fitted. It clears the teeth by 3/16" - and when fully engaged with the teeth - the cover of the bendix also (just!) clears the teeth. So - no problem that I can see.<br><br><br><br>
And that's a standard early type starter - with side fitted brushes - and no extra spacer fitted!
I then tried a later end-fitted brush starter - it too cleared the ring gear - but only about 1/8" this time. It also cleared the cover when fully engaged - picture for that a bit too blurred to publish! <br><br>
So - for my 1275 marina engine - it appears an older side brush type starter will be best - although the later starter would still be ok - just a little less clearance.
Hope this helps!

SO the spacer will be needed to stop the bendix coming back to far then

mine did and was all right the other way as shown

the laser cut back plate moves the starter motor round to clear the bulkhead if not using the minor backplate

i have another laser cut plate £40.00 colection only

[bmcecosse]

No - in my case I won't need any extra spacer! Can't speak for others of course.

bmcecosse,

thanks for photos.the splines on my starter look a little longer than yours.which could explain the problem.Could you possibly measure lengh of thes splines they look abot 20 mm or so.
many thanks
Ian

[bmcecosse]

By 'splines' do you mean the drive teeth on the Bendix ? Or - the twisty spline part where the bendix advances to engage the ring-gear ?

[ozzies]

the lengh of the drive teeth on the Bendix.thanks

[bmcecosse]

16mm on both starters. I was thinking the easiest thing to do will be to cut a coil off the big spring - you should be able to do that without dismantling the bendix - although you would need to make two cuts and take it off in two halves! Maybe just half a coil would give enough clearance - worth a try.
But if you feel more comfortable with simply grinding down the ends of the bendix teeth - that should work well enough too. Just be sure to put a chamfer on them to help them engage the ring gear.
I can't see ANY need for the 'spacer' that is much talked about!
