crank slinger?????????

[doublezo]

im getting ready to put the crank back into a 51 merc engine. ive noticed that it doesnt have the front slinger on it. (the slinger that goes on next to the crankshaft gear) is this supposed to be on there? i have one on another motor but cant figure out how it goes on, or how to get it off. help! thanks.

Slips on in front of the gear with the flange facing out. The spiral sleeve goes on next.

how would i get one off of a crank? the one i have is stuck it seems. i dont want to mangle it because i need it for the other motor. thanks.

Little tapping, little prying, little penetrating oil.
Or use a gear puller to pull the gear. (the slinger will come off with it)

ok, so just to make sure, 1. get the dowel pin out, 2. get the spiral off somehow, 3. pull slinger.

Yes pull the fan belt pulley woodruff key first.

The factory manual says to pull the pulley spacer, & gear at the same time. They used a special puller to do this but I have a non-factory type puller that works.

thanks guys. got the key out . what a pain. looks like im out of luck for today, im walkin away. . will i to need a press to put it all back together?

The Merc overhaul manual shows a figure with them tapping it back on using another special tool. A piece of pipe the right diameter & length would work OK.

back at it with a new gear, slinger and spiral spacer. the gear went on fairly easy, slinger was no problem either. i need some advice on the spiral spacer. it fits really tight. any tips? we boiled it and still a no go. its been a lot of work to get it barely on. the spacer is new from macs.

I lightly heated my last on and slipped it on? Maybe not the right way but it worked.

It's a tight fit. Find a piece of pipe theat will slip over the crank snout and pound it on. You do have it aligned with the keyway I hope.

It's been awhile since I did this, but I think you can use the old gear to drive on the spiral seal sleeve, put the sleeve on, then the old gear, then a piece of pipe against the old gear and tap it on. heat up the spiral sleeve first, have everything ready to go before the sleeve cools down. make sense?

thanks for all the help. the gear and slinger went on fairly easy. the spacer was a nightmare. its on and now the crank is in. hopefully get to fire the engine in a few days. thanks , brian.
