Is this tool worth the money for re installing the crank? I know with the hod rod cranks being tight on the right side I thought it might be a good idea so I don't ruin a crank bearing or crank.

I can add it to my order at Honda of Toledo so it will only be 45 bucks.

Does this thread onto the flywheel side so you can pull the crank into the bearing?

What about the clutch side, can I pull the crank through the bearing on that side?

You most definitely want to use a puller to install the crank. I can't see pics of that tool to tell exactly what it does.

I use the Tusk crankshaft puller and case splitter tools when I do my bottom end jobs. They work like a charm and I got them from Rocky Mountain ATV. It works for pulling the crank into the left and right side case halves

However i'd rather have the official Honda tool that's made in Japan. If it's a crank puller then i'd definitely buy it

Scott, that is only one part for the honda tools needed to pull the crank in.

I posted a honda tool list that is in the faq, and important info section. The honda tools will be pretty expensive compared to the aftermarket setups, of course.

That list will show the other thread adapters, collar adapter and pull bolt needed. If you want to check prices you can run the numbers on the web.

I am thinking I will just get the Tuck tool. That will pull the crankshaft into the bearings from the flywheel side and clutch side? I dont want to have to purchase 5 different pieces for the Honda brand tool.

Thanks

What do you guys think of my homemade crankshaft puller? I made it using a 12x1.25 long lug nut welded to a 1/2" coupler. I will use an 1 1/4 steel pipe to but up against the bearing. This is for the flywheel side. On the other side I will use a 10x1.25 wheel stud welded to a coupler.

I should be ready to put the cases together this weekend. The only bad thing is when I put my order in at Honda Toledo East I forgot to order the base and head gasket and am trying to get one locally by the weekend. It's frustrating because I was putting in to many hours at work and was rushed when I put my order in. If thats all that goes bad I guess it will be good.

I put the cases together last night without the bearings, seals or gaskets just to see if they were straight and it looks good. There is a very small bit of light that I can see towards the front of the engine where the crank goes but that should seal up with the gasket right?

Looking for tips on where to use the blue loctite. Should I put it on the crank seals when I put them in? I plan on putting some on the retaining screws for the bearings.

The next thing I plan on doing is baking the left case @ 200 degrees for 1 hour, then put the frozen bearings in that side first. My crank is in the freezer now and then I plan on putting the left case back in the oven and hopefully the crank should slip into the left case along with some help of my homemade puller.

I hear mixed results as to taking emery cloth to the right crank bearing to make it more of a slip fit. Thoughts on that?

Thanks

shouldnt need to go nearly a hour in the oven. 250f for 30min should do the trick. if emory cloth is like scotch brite then i cant see it being very affective against a bearing race but then again ive never tried it

Emery cloth is like sandpaper.

My center pawl specs out at .165 and the service limit is .190. The left and right spec out at .195 to .197 so we are good there. I am not finding much out there for the center pawl, a used one on ebay for 50 bucks. Any ideas on where I can get one?

Its coming together and could have it running today. I was using 1/4" stock thinking I could use that to put the left crank seal in but for some reason it went in to far. Anyone think there will be a problem with it being set in .275? The bad thing is on the bottom it measures .305 and on top its at .260.

One other question, is my gasket going to be OK? I had the Honda dealer pull the crank into the bearings so I didn't have any problems with that. At first I thought the gasket got twisted but it isn't in there to far and seems to be straight.

udontknowme · « **Reply #56 on:** March 29, 2015, 12:42:41 PM »

first rule of thumb, never let a dealer touch your bike. likely it was a high school kid doing the work. the amount of money you payed them you could have bought the tools yourself

the gasket looks sucked in to me, atleast from the pic it looks that way. buy some tools and do it right yourself.

Actually I have had good luck with this dealer and they didn't charge me much at all. I tried pulling the crankshaft into the first bearing and didn't quite get it all the way. It took the mechanic 10 minutes to fix it.

I just performed a leak down test and that is good now.
