I'm going to replace my starter, I've never done this before... From the pic of the new one it looks like it only has 2 bolts holding it on. Does anyone know exactly what size socket I'm going to need? I'm going to have to borrow tools... Any other pointers?... Much appreciated

 

And it's a 1991 F150 inline 6cyl 4.9L engine

 

One of the easiest starter motors to change. I don't remember the exact size but its SAE and should be in any decent 3/8 socket set. Make sure you disconnect the negative battery cable, wear eye protection, and that the parts store give you the correct starter motor. The manual trans and auto trans use different ones. I paid 141 bucks for mine from Napa a couple of years ago.
YMMV

Almost positive its a 14mm socket. Just unplug the neg battery cable and the connections on the starter, put in the new starter and clean up the connections with some sand paper. Plug the battery back in and you are good to go

I would also get some dielectric grease to protect the wires from corrosion .

 

Hmm.. Its either a 9/16ths 1/2"or a 13mm. I think. Might have to crawl under. I think the power wire takes a 10 mm. All this aside, you never know, someone has probably been there before and used whatever they could find laying around if they misplaced one. Anyway.. if your gonna own an old truck, you may want to seriously consider investing in a minimum set of tools.

Finally, when torquing the mount bolts, do not over tighten. The bellhousing is aluminum whose threads can be easily stripped.

 

Or like one of my trucks the aluminum will oxidize around the bolts and break the bolts

 

It's 1/2". I've only had mine out like 100 times.

 

^^^^^ Funny sheet...Maybe a BFH to assist

 

Thanks for telling me about disconnecting the battery lol is have shocked myself.....

 

You can run a ground strap from one of the starter mounting bolts to the frame, allows more current to run thru the starter and pulls away heat build up. If your truck has a fire wall mounted solenoid there is no voltage at the starter unless to turn the ignition key to start, but it is always a good idea to disconnect the negative cable anytime you work on your truck. And go to harbor freight and get a set of sockets.
