Looks like the new starter has not survived its sinking!! No amount of fresh water bathing and drying seems to free up the shaft. The local auto electrician says that being the inertia type ( rather than pre engaged?) and having the solanoid in the nose makes it more complicated and easier to suffer in bad conditions. He claims to have a bracket that will enable me to fit a pre engaged more robust starter, are there any thoughts on this please??
What have you other guys got fitted ? The existing starter is a bit long so that I have to remove the oil filter and the oil pipes to get it in and out, a shorter unit with the solonoid on top would be easier to get in and out.
It is getting to the stage when I am concerned about shutting off the engine in case the starter wont go.. not much comfort when you are out for a sail!!
 
If you have to opportunity to swap from an inertia type starter to a pre-engaged type then I think you should take it. The pre-engaged type is in fact marginally more suitable for diesel engines and they have replaced inertia types on most if not all engines now. Consider it an upgrade! Also repacing the unit will ensure that you do not have problems with corrosion waiting to strike at a later and inconvenient time.


Although it should be possible to strip clean and lubricate all of the main moving parts of an inertia starter It probably wont be possible to do anything with the solenoid if that has been dunked as well. Inertia starter solenoids are not an integral part of the machine so it may be mounted where it has not been affected. I do not understand your reference to it being "on the nose".

If you had a pre-engaged type there would have been a few bits that it would not have been possible to dismantle, The drive assembly that carries the pinion, in effect a unidirectional clutch, is not serviceable. The electrical end of the solenoid might not be accessible either. Because the solenoid of a pre-engage starter also operates the mechanism that engages the starter with the ring gear on the flywheel it is an integral part of the machine and could well have been dunked although it is on the top.
 
Hi
I agree with your electrician,before I had the inertia type on my 4108,I change it for a new type which much more efficient but you need to put a bracket as your electrician tell you

When Hubby replaced the Solenoid on our Perkins - it was bolted to the bulkhead well away from starter motor. The starter motor as well was a standard job from breakers yard.

Just visited the auto electrician, he is suggesting that the pre engaged type type starter will fit into the hole on my engine casing. Just looking at the nse cone thing he has given me to try it does seem possible ( the whole nose cone will effectvly be inside the housing) The starter which would fit onto this is shorter than the one fitted and has the solonoid on top, it looks like it would be easier to fit than the existig one.
So back to Conwy asap to see if it will fit.
Thanks all.
 
My Perkins 4108 has always had a pre-engage starter from new. The starter has it's own negative connection. Automotive starters usually do not have negative connection terminals. They depend on negative connection through the casing. If you are to use an automotive starter you should be aware of this.
