Honda Spree and Elite 50 Forums

Hi guys, Im new to the forum but it has already proved helpful. I have a 86 spree that i picked up the other day. It dident run, just turned out to be a loose carb. Once i got it up and running I head some really nasty sound coming from the engine area. I removed the belt cover and the alternator cover and dident see anything wrong there, except for oil in the belt area. IM sure the bearings are bad, so i tore it down the rest of the way today. I have everything apart but the crankcase is still stuck together. It is loose from the gasket and I can wiggle it slightly. Wow this is getting long winded, my question is is where can i get a tool locally to split it? Is there some kind of puller? Could I heat the bearings with a propane torch? Thanks in advance, Magnet.

well. there is no specific tool(that i know of) that can pull the crank case apart, you're going to have to replace the gasket anyway, so a flat head screwdrive and a hammer will work. just dont messup any of the medal stuff.

A few little dings are ok, they won't effect performance.

Im not so sure about that idea, the case on a 2 cycle needs to be airtight. Thanks for your quick response.

I'd visit a shop that deals with 2 stroke engines. If you have a scooter/moped shop that deals with case splitting, they'll definitely have the correct tool for it. Another option would be to seek out a shop that services dirt bikes as they use similar tools for the job.

Putting the case back together requires you to use a bead of Hondabond (liquid gasket). Don't use anything but Hondabond when you seal the case halves together.

Dude, seriously? That's your advice? *? While we're going for bad advice I've seen on the board, why don't you tell him to blow out the petcock good with compressed air? Or spray WD-40 on the clutch pads? How about drilling out the idle jet with the smallest drill in your set, maybe a 1/16? And make sure to dump some nitromethane/alcohol/sugar in the gas tank while you're at it for added power? All good ways to F up your scoot.

Read the Honda Spree service manual. Yes, there is a tool. You can probably make one yourself or adapt from a similar type puller.

I'm more than certain that a few guys in Hawaii have done ultra ghetto work all psyched up on meth doing stuff like the screwdriver case splitting thing... I guess if you have no other option left to you, it might be worth trying however being that this is a technical help section, I'm bound to provide sound help.

If you intend on doing a lot of case splits, then investing in a tool is probably a good idea. I picked mines up from Honda directly from their parts department a very long time ago. If you don't intend on working on a lot of bikes, then I'd go around to some bike shops that's done case splits and see if you can work something out with the mechanic there... buy him lunch and maybe he'll split the case for you for nothing.

If you don't have a tube of Hondabond with you, go out and get a tube of it... if you intend on seeking help from another person, bring the tube with you as it's needed for reassembly, the 2 case halves must be sealed tight.

New crank seals are probably a good idea to install in replacement for the old ones while you're at this stage, also inspect the bearings as you said. We use a high wattage heat gun to accomplish the same thing (mostly due to the fact that it's a lot safer). If you intend on changing the bearings (which I do recommend doing), you could pound the old one out but for the install, heat the case in order to expand it, then the bearing should drop nicely inside of the seat. Takes about 10-12 minutes of solid high temp heating with a heat gun. Make sure you take all safety precautions since touching the wrong stuff = burn scar for life.

Whoa. sorry, no need to grill me for that.

When i took my crank case apart, it just pulled right off.

Thanks for your replies! I had no idea there needed to be Hondabond on the crankcase halves. I think im going to take it over to the dealer and see how much they would charge me to pull it apart and just throw the new bearings in. I dident notice in the service manual it shows a tool to pull the case back together, it just looks like it pushes on the case as you tighten the crank.

07935-GK80000 is the part number. I can't find much on it.

492.5 Euros is about $690.

So are you saying just tap the case and it will come off? Like i said, the case is loose from the gasket. It just seems like its stuck on the shaft.

Really I think the screwdriver isnt such a bad idea. If you do it one side then put in a washer then do it on the other side the same way it wont put all the pressure on one side I had to do that on my crank case cover because the previous owner had an extreme amount of sealent to replace the gasket.
