on ym 300zx, im trying to do a front crank seal, but i cant get the gear off, there is no way a puller will go on at all, wtf should i use????

 

Pics?
usually heat / cold and or a BFH work

 

harbor freight or some place were they have specialty tool or even autozone rent-a-tool service. get yourself an adjustible puller were you would have to drill into the pulley itself. Or lubricate the hell out of it and let sit awhile and pry with screwdriver

 

When I did my cam seals, timing belt, water pump, etc. I was going to do the crank seal as well. But I ended up saying screw it for now, but I remember how I was told to get it off:

You need to tap a couple of screws into it so you have something to grab on to. The downside is you will need to replace the gear.

 

Yup thats what I had to do. I tried heat...soaking it with PB, WD40 and others but just couldnt get it off.

I drilled two holes and tapped them so I could put a steering wheel puller on it to pull it off. The gear isnt very expensive.

 

first thing first...get a new gear. also pick up that big washer being it.

on the old VG i had to break the gear in 1/2 to get it out. that means i had to drill a few relief holes and some fun with a dremel cutting disc to get the pulley out. after it cracked the crank still didn't want to come out. i had to use a nice big 2 claw puller to get it out.

 

hmm so after trying heat, pb blaster soaking, i managned to nudge it a lil

but its not going anymore


i guess my only option is drill it??

 

i used 2 of those long a$$ flat head screwdrivers (the ones that the shops use that the tip is at an angle) and just put it behind the crank pulley and just start prying side to side and it will come out. eventually i ended up buyin' a puller and used it since then. sometimes the pulley just needs a nice little prying and it will slide out with no problems. luckily it happened to me on both my '93 and when i had my '89.

 

umm big screwdrivers with angle tips = pry bars

i didn't want to risk messing with it since the crank snouts are known to break on the VGs.

 

thats what its called. thanks for correcting me Danny. i did it once with the pry bars but then i just bought the big claw puller. didn't need to tap any holes.

 

i whooped and beat on mine the other day. turns out a 2 jaw 6inch puller did the job. wish i'd bought that before i wore myself out and tore up my pulley and housing from prying.

 

On my older VG, I just cut through it (making sure not to hit the crank snout), and pulled it off. I had a replacement from a spare engine I had laying around so it wasn't a big expense for me.
