Sprint starter motor alternative

[tony g]

November 2017 I fitted this starter to my Sprint. It needed a 14mm spacer making and a bit of fettling as the gears were in mesh too tight so I used a dreadnought file to "move" the starter out of mesh about 0.5mm. Been started up at least 3 times every week while I was working on my coolant mod and has been very good. I'd even say it spins the engine faster than the truck starter that was original

So, what's the replacement from, Tony? And can you supply spacers to cope?

Cheers, Steve

Its from a 200 series Rover Steve but not sure which. Part number is ADU 8919. My spacer was a one off so Im not making them no sorry. A lot nicer to fit

Was the spacer flat? A dwg to a laser cutter would see a quantity made in a flash...if you’ll pardon the pun.

I wonder if the Rover starter could be rebuilt with a Dolly dog gear?

[tony g]

Plate I had made is flat but with the spigot machined on too. The gear on the starter is standard (Rover). When I first had it made I told the guy to copy the details of the Sprint one but it was in mesh too tightly so I relieved it to fit with files etc. The offset from the bolt centreline to the pinion centreline must be a tad different. I have about 5 of these starters in stock,all new but from 1990. I had bought some clearance stuff years ago thinking they'll come in handy and 15 years later hey presto lol.
I'm flat out at the minute but if I get chance I'll get both starters measured properly on the cmm and get a drawing done.

that part number cross references with the following :
ROVER ADU8919
LUCAS ... LRS00541
VALEO 455731
BOSCH 0986014721
QUINTO... 8055541
FRIESEN 8055541
DELCO REMY DRS3126

looks to be a good alternative.

Does anyone else use one of the new high torque ones?
I have an RAC406 on mine and it seems to do a pretty good job - so far.

[tony g]

Is that from another car Russ or a bespoke high torque thats £200?

A couple of people mentioned fitting them 8 years ago, you could ask them how they got on for a long term test.

So far as I know the RAC406 is listed for Sprint and TR7. I run mine on a Sprint engine actually IN a TR7 so that seems to cover all options.
Been good so far(!)

Yes; Doesn't time fly when you are having fun. I saw my posting there from " Post subject: Re: Starter motors. Posted: Wed Jan 06, 2010 6:00 pm"

Just over 10 years ago ! Yes the 1850 one and the MGB are still going O.K. !

For most starters, a change of the inexpensive solenoid transforms the motor.

Yes, fitted one more than 5 years ago to the Pageant car and it really is a fit and forget. Mine came with the option of the additional terminal to the ignition. Never had a single issue, works perfectly every time. Might have been expensive to start with but if I needed to would do it all again.

Yeah, that was my thought. Starters are pretty simple old lumps, most would need an inexpensive rebuild. A burnt out terminal or sticking solenoid, not difficult to do.
