Perkins 4107 Starter

My Perkins 4107 appears to have problems starting. The starter motor seems to be more sluggish than it should.

It was not turning over the engine enough to start - so I pulled the battery and headed down to the battery shop. They said "Its at about 60%, but should be heaps to start your Perkins". But, it wasnt. So I bought a fully fresh one.

Well, the brand spanking new battery will start the engine, but only when fully charged, and the engine has to start within the first few seconds, or else the cranking speed diminishes rapidly.

So, shecked my wiring. Pulled all the wiring from battery to starter and checked. Some was badly corroded, Reran all the heavy duty cables with fresh ones, and shortened the cable run by 2/3 at the same time. Mild improvement only!

So what next - is the problem within the starter motor itself? Do these pack it in with sluggish and short cranking duration? What is the fix?

Re: Perkins 4107 Starter

Pull the starter and take it to the shop. They should be able to bench test it

Re: Perkins 4107 Starter

Yes, after many years a few things can happen to a starter that will slow it down. I had to have my Bosch rebuilt and now it spins like crazy.
kind regards,

Re: Perkins 4107 Starter

Just a heads up, you will need an extension to get to the imside bolt.

Re: Perkins 4107 Starter

Well,
Pulled the starter motor last night.

Both Chief engineer and the auto electric workshop warned me about the 3rd "inside bolt". But, there was none - and, unusually, this task went without a hitch.

Pulling it was no issue, except had to pull off the fuel filter and lines to make enough room to get it out.

Damn boats, everything is built around the engine!

Re: Perkins 4107 Starter

Its the starter motor - totally stuffed.

Just got back from the sparkies workshop, the armature windings have burnt through.

Trying to find parts to repair is a "difficult". Does anybody know of a suitable replacement for this starter motor:

LRS189 - 26163F - M45G

13 tooth.

Re: Perkins 4107 Starter

Bill, there was some info posted on the forum about replacement starters, but it was a while ago. Try the advanced google search of the forum.

Re: Perkins 4107 Starter

Yeah - I read that post.

the issue with the 3/4 inch spacer was picked up by my sparky. He says he can probably find a starter motor to fit, but will require a big spacer (he reckons 25mm) and possibly filing the teeth on the flywheel to engage from the opposite side.

Then modifying the starter to insulated earth return (steel hull). etc etc etc...

Hows the refit going - constant and never ending

If you are on the east coast try API MARINE - Manufacturers of starting motors, alternators, power trim/tilt, motors and pumps, water circulating pumps, and hydraulic hatch system They have just about every starter and alternator ever built.

Re: Perkins 4107 Starter

The saga ended today!

1 starter repaired, and sourced a full "new" rebuild. Now I have a spare.

However, the best advice was from the workshop who repaired the old motor (I think I am in love with these guys). They told me to check the voltage drop across the leads to the starter.Well, was dropping 1.8v before getting to the starter motor!!

I opened up the old cables with a razor. 30% of the cable was red dust, and the rest of the cable was black. Well, it seems its not bullshit that you should use tinned wire on boats.

Anyway, the perkins starts a treat. Wooo Hooo.

As a little aside, the rebuilt starter motor I got in form England ($700) had the positive and neg mislabeled. Can anybody guess what happens when you start a Perkins backwards?

You may ask, why import from England. Well, none of the yankee suppliers suggested responded to email.
