1991 Range Rover starter replacement at 169K miles

Symptom: Starter motor runs (free-run) but does not engage.

Concern: Frozen bolts since I believed this was first removal, over 13 years.

Key Tools: 8mm hex socket, 3/8” breaker bar, 6” extension bar, 13mm wrench

1) Disconnect Battery
2) Remove heat shield from exhaust manifold (2-13mm bolts) to access top bolt
3) Loosen and re-tighten lower 8mm hex bolt (this gives indication of difficulty)
4) Clean top bolt if required (carb. cleaner, rag on small screw driver)
5) Insert 8mm hex into top bolt with 6” extension bar, use breaker bar from below.
6) Note: upper bolt holds ground strap going to frame
7) Remove lower bolt (which also holds lower heat shield)
8) Remove lower heat shield which is clipped on to solenoid
9) From above pull starter back-end up and remove small wire from solenoid
10) Cut plastic strap holding large cable to solenoid (this is + feed to chassis)
11) Remove 13mm nut holding battery cable and chassis + feed
12) Reverse procedure for installation

There is limited access from below but sufficient. Rotate hex socket for best alignment for breaker bar. I tried using 6”+10” extension bars on top bolt. It cleared the engine mount but I could not get a straight shot at bolt. This combination may work with an universal joint (I tried this before removing heat shield.).

Original starter: Magnetti Marelli M78 (aka Lucas) manufactured June 1990

I took starter to a local electrical rebuild shop. Cost was $135 pre-tax.

Failure: This is a gear reduction type starter. Plastic gear used in reduction was stripped of teeth. Of course, many other items were bad condition.

Replacement starter: Bosche (I believe SR0802X). It was about 1.5” longer. Shop said it was better, used in later models. I read it is better cold start. Same 1.4kw rating.

Below is application and substitution charts I found, use at your own risk !!

I checked many sources with many different combinations of model year and P/N recommendations. This seems to be the best overview. From this is appears starters can be broadly substituted contrary to most sources of information but do your homework.

thanks for the instructions.

The top bolt is pretty much impossible to get to from under the truck though. I could not even touch it. I hit it from above...half the time I was splayed across the engine (chest on the thing that says 3.9, left arm sneaking down around the passenger side headers).

It took me a while because the hex bolts fill with crud and make it really tough to get the hex socket into. I used smaller hex sockets and "wallered" the socket out a whole bunch. Even then, it was really really tough.

Still not done.
