Hello I am currently having starting issues with my 87 f250 with a 351w. The truck was my old mans, it was a straight six stock but he dropped a 351 into it. Due to him not knowing the year of the motor I ended up buying the wrong starter for it. Twice. Then finally I got the right starter a high output one from power master and all was well for a week or so and now when I try to start it sometimes it takes a couple tries, sometimes I go to start it and it makes a awful grinding noise. Starter is new, solenoid is new. I assumed I must have damaged the flywheel and all the teeth are there just the very tip of them look a little grinded as well as the tip of the new starter but it doesn't look bad. Also sometimes when driving every now and then
I can hear a clicking noise what sounds like is coming from my flywheel. Any idea what could be causing this would be greatly appreciated.
This is a picture of what my flywheel looks like, the ends are a little grinded
Luckily I haven't had starter problems but I'll try to help.
Is this auto or manual?
It does make a difference for either one. What was wrong with the other 2 starters that didn't work? It's hard since you know the engine was swapped so don't feel bad about it. To bad you don't have the old one to compare to the new one.
If you have a torch and are mechanically inclined, you can heat the ring gear, take it off the flywheel & turn it around, reinstalling the fresh side towards the starter. For $20 bucks you can buy a new ring gear and swap it onto your old flywheel. What I just did to be on the safe side (who wants to pull a transmission twice?) was buy a new flywheel and clutch, replacing everything at once. Just depends on your fund situation.....
Thanks I'll give that a shot, and it's a manual transmission. The issues with the old starters were they were both starters for like 158 tooth flywheel and mine is a 164 tooth.
Have you rotated the engine to see if the whole ring gear looks like that, or if that's just a bad spot created by the wrong starter? Engines tend to stop in the same position every time you shut it down, so this may be the only part of the ring gear that's damaged. It ***MIGHT** work to file those down, and create new chamfers on the teeth (use an undamaged part of the ring gear as a model) to help guide the bendix gear.
Did you check the bendix gear on your current starter for similar damage?
I wonder if reversing the ring gear would work. Haven't looked lately, but I doubt the aft-facing side of the ring gear has chamfers on the teeth to guide engagement of the bendix gear.
