All engine faults/repairs/maintenance Replace starter motor

Anon:  Starter Motor & Bush replacement - 2.0 litre  Air-cooled

Preamble: We are complete van novices, spurred into doing this job ourselves because I was too tight to pay for the mechanic and I thought we should learn something about the van.

Tools required

• M12 thread tap (I bought a whole cheap set for about £3.00 from eBay)
• Screwdriver with a piece of fairly thick cloth – an old t-shirt would do
• Spanners/socket set
• Pair of plastic goggles (for the health of your eyes, rust dust and flakes are serious nasty scratchy scratchy irritants!)
• Axle stands

Beforehand

• A new bush is usually a very good idea, this bush is an oilite(porous bronze)) bush and fits in the bellhousing supporting the starter's pinion extension
• Make sure the new bush is soaking in engine oil overnight. (Maybe have a spare soaking, just in case…!)

How we did it

N.B. This is not the recommended position for axle stands. Here the van is resting on the engine carrier. The recomended mounting points are just forward of the rear wheels (on the outside of the rear cross-member)

Jack van up and place on axle stands – one each side. If you are really skinny, or can gain some height by parking on the kerb, you may be able to access the starter motor.

Now disconnect the battery, then crawl underneath and see if you can locate the starter motor. Haynes says to remove the rear wheel on the drivers side, as this makes access easier. I’m sure it does, but as our wheel refused to budge, we did it with the wheel in place! Crawl under the van, behind the drivers seat and look around you will see the starter. Along with bits of rust, grot, mud etc., so safety goggles if you are comfortable with them are useful.

The starter looks something like this: It is two cylinders fixed together with wire connections on the end of the smaller cylinder (solenoid, to give it its proper title).

Look carefully at the connections, and note where each wire goes. When you remove the wires, take the opportunity to wire-brush or emery-paper the connections to ensure good clean contacts in the future (use vaseline or Holts NoCrode on this connection, else it will corrode badly after cleaning - Ed).

There are a couple of bolts for the starter. The first one was obvious, but the second one had us foxed as the nut undid, but we could not see where the bolt came out…until we pushed it a bit, and I noticed a bolt moving in the engine bay! It’s a bolt with a funny shape head: It will only sit in the hole one way! Once the bolts are out, you can remove the starter motor.

This is the one on the air cooled

The water cooled top starter bolt is called a "cheesehead" in ETKA/ETOS and looks like this (this is the end that is forward of the engine bay) 8mm allen/ hex key

Once the starter is out, If you look into the large hole that it came out of you will see your starter motor bush, a small piece of copper looking tube (oilite bush - Ed!) If you have been having problems with starting the van, your bush is probably very worn, and may even be in pieces. (also see bush removal page) You now need to use the M12 tap to remove whatever is left of the bush. Hubby said that this was fiddly, but he managed it eventually. Our bush came out in one main piece, but with holes in it where it had worn. Next hubby wrapped a cloth around the screwdriver in order to remove any tiny pieces of bush which remained. Some small pieces came out.

Now you have to put the new bush in. Useful here to have a longish bolt with a large washer, so that you can get the bush in nice an straight (the washer stops the bush falling off the bolt.) Once it is properly in place, replace the starter, do up the bolts, re-connect the wiring and give the starter a whirl - if it works, you can then give the van a whirl too!

Hubby has now had the starter off a few times, and can do it fairly rapidly with the assistance of teenage son!

Hope this has helped someone, somewhere. (it will, thanks - Ed)
