Tool Questions.

[ddennis]

Hi Guys! ok..a week or 2 ago I posted a message regarding working on my Father in law's 60 hp 1993 merc...and you guys were very helpful. I am going to Louisiana this weekend to pick it up, however an uncle is arguing with me and to my father in law saying that I can't rebuild it cause I don't have "mercury tools". He claims that you cant work on one without specialized tools only available from merc. I have never heard of this...merc gurus...whats the truth?

Hi,
I just overhauled a 60hp last winter and never had a tool from mercury.
I did make a cyl sleve to transfer the pistons from the bench to the cyl. I have a machine shop but it could have been done with out the sleve. also made some little shafts to hold the needle berrings in place till we pressed the wrist pins in. The new ones are easier to work on than the pre 88's. I made a puller to pull the flywheel. It comes off hard. It is on a tapered spline on the crank and once it pops it comes right off. Just need a strong puller.
you need a good book. preferably from merc. I had a clymer book and it was a little too general and covered every motor but mine in a lot of cases. Just need some basic automotive skills. I just got mine on the water the other day and it purred like a kitten. Had some minor issues but had a lot of power and idled smooth..........good luck.................Jerry

Re: Tool Questions.

The only special tools that would be nice would be ring compressers but you can stick them in the holes 1 at a time then install the rod brgs and caps take a good grease to lay the brgs in and some 514 loctite for the crankcase

Re: Tool Questions.

You do need a mercury type flywheel puller. It threads into the flywheel and presses down on the spline. Anything else will wreck the flywheel. Replacing the pusher with an eye bolt makes it a kosher engine lifting device.

Otherwise, A merc type ring compressor makes things a lot easier where it's pretty easy to break a ring, and an assembly rod helps put in the wrist pin bearings.

I would invest in torque wrenches, also. Bolts need to be tightened properly, and the holes in aluminum can be easily stripped.

hope it helps

Re: Tool Questions.

thanks J Martin, I already have 2 pretty good craftsman torque wrenches, one in inch pounds and one in feet pounds. Where would be the best place for me to source a merc type flywheel puller. Would a standard ring compressor work? I have one (some where) for smaller bore engines back from when I raced motocross and did my own engine work.

Re: Tool Questions.

You can get the combination flywheel puller/lifting ring for Mercurys on ebay pretty cheap. I think I paid $30 with shipping. Heres a link:

Re: Tool Questions.

That puller appears to use a course thread bolt. I would be sure I got one with a fine thread grade 8 bolt.

The Mercury genuine puller is such, as is the one I bought on E-bay. I can't find one on e-bay right now, but they come up from time to time.

Don't worry about the eye bolt. A fresh, longer hardware store bolt and a loop of chain works fine with the puller body.

I don't know about the ring compressors, just heard that mercs are a little tricky without the right tool.

hope it helps

Re: Tool Questions.

The fly wheel puller at the link above is what I bought. The course thread eye bolt threads into the adapter which screws into the fly wheel. To make it a puller, you just screw in the big bolt into the adapter.

Yes, I know that. What I'm saying is that the good pullers use a fine thread driver screw, and they develop a lot more pull with the same torque. Believe me, it's sometimes important.

The cottage industry makes most of them coarse thread because the coarse thread eyebolt is cheaper and easier to find. If you get a good one, without an eyebolt, a fine thread grade 5 bolt for about 50 cents and about 5 links of whatever chain you have laying around works just as good.

hope it helps
