    Ok, I've got my high schoolers rebuilding a 1949 Ford flathead. Not sure what isn't lining up here. They reinstalled the camshaft and the rear gear for the oil pump is not in far enough. It seems like the camshaft could sit about 1/8" further in, but it doesn't seem to want to go in more. We didn't notice this until after all the valves got installed.

    Ideas?

    The late idler gear at the back is on a shaft that comes out with it, with athreaded hole for either a puller or just a piece of threaded rod made into a slide hammer...I'd yank it just as process of elinination (and to measure, see it it's all the way in) and see if cam can be moved. I ***ume pump is still out.
    Noe, if you need to get cam out...to avoid dealing with valves, there's another little task for your schoolers: Pop over to the wood shop and make 16 wedges of thick plastic, plywood, fiber board, etc....U shaped slot in each, open ends of the U tapered. Rotate cam, tap a wedge under each valve as it opens...once all 16 are propped open, either turn engine upside down to control lifters or rubber-band the hell out of them. Now cam can be yanked out for psycho****ysis without doing the #$@##$ valves again!

    Ok, the idler shaft is not in far enough, but I cannot get that thing to budge! I tried getting in out with a slide hammer and in with a br*** hammer. No love...

    Ideas?

    Last time I had one that wouldn't go in the fuel pump rod was in the way, picked it up with a magnet went right in! Yours looks like it is farther in than mine, may not be the rod.

    giJoe Has the gear been out at some point during your build? And possibly be in backwards. I thick they are offset one way. I am not sure Ford may have used several different gears but it looks different than the one in my engine. Check out the first and second post on my build thread pics are not great of that area but i think you will see what I am talking about.

    WE didn't take it out when it went to the machine shop. I may call the guy and ask him. But right now I wasn't able to even get it out. I may try harder, but didn't want to go too crazy with the slide hammer. I used to have the nickname torquer for my overzealous muscle...

    So, I'm a pretty strong dude... I've tried using the slide hammer to get this gear out and it isn't budging. Should I be worried about something? I really don't feel like breaking my block. Do I just need to go harder? I'd hate to snap something...

    Try improvising a puller...make or find something that will bridge the hole and support on each side, a U or a cup of some sort, and make it a puller with some threaded rod, nuts and washers...insures straight pull, allows you to let it sit under pressure. Tension, really.

    We just started getting a piece of angle iron ready to make a puller...

    x 2 ..........the gear is offset and I know this because I put mine in backwards in my 8BA and had the same problem as you :(

    Only way I could get it out was by making a puller so it looks like you are now on the right track

    Good luck with it

    The gear is definitely on backwards. Need to pull it out and reverse it.

    A motor that I got last winter had gotten a lot of water in it over years of sitting out in the open. I broke the oil pump getting that out. The idler gear that drives the oil pump was rusted in & wouldn't budge. After doing some computer surfing I found where Ford ( I think it was K.R .Wilson) had made a puller to get the idler gear out, so I kinda copied it. I made it out of 3 1/2"od x 3" long pipe with 1/4" wall. I welded a cap on one end, drilled 3/8" hole in it & welded a heavy washer at the hole on both sides. I used a 6" long section of 3/8" allthread & 2 nuts. On the one end of allthread I ground two flats for a 1/4" wrench so you can hold it .I cleaned it up a little in the lathe & this is what I got. IMG_2581.JPG IMG_2582.JPG IMG_2583.JPG Screw the allthread into the threaded hole in the idler gear. Tighten the first nut down against the idler gear & slide the tube down over the allthread to where it seats against the block. use the second nut to turn against the cap on the pipe & hold the allthread with the flats with the 1/4" wrench. Works great. Bill
