Hi,

as a beginner in nitro I try to do a list of tools & equipement needed for maintaining an engine in perfect condition.

This includes the tools for the assembly and disassembly of the engine, its tuning, repairing,...

Please contribute in this thread, it might be helpful for many beginners

OS engines glow plug wrench (it's the best one because it grips the plug)
Hudy ultimate engine tools, for removing and installing bearings
Ladies tweezer of good quality, for removing/installing G-clips for the piston pin
hex bits set and Bestool Kanon 20LTDK torque screw driver
Set of digital calipers, Hobbyking sell a good digital caliper for almost nothing, needed to measure crank pin and con rod wear
Large number of stamps and envelopes, so you can send your P/S/R sets to RayAracing for resizing when you've run out of pinch

I think that covers it.

For all my allen bolts, I perfer using Torx bits (6 point star bits). I have a variety
of 1/4 inch socket tools. Including a Snap-On screw driver with a flexible shaft,
and a 1/4" battery powered screw gun.

To be honest a bearing puller is a very high investment for a thing you do not use often and the job can also be done without it.

what you need:
- Indeed a good plug wrench
- a good solid and long screwdriver to tune the carburator.
- Tools to mount a clutch (fly wheel grip, wrench for the nut and maybe a tool for mounting the shoes)
- The right tools to open the engine (that may differ per engine brand)
- afterrun oil, also ideal to use when assembling an engine

You need a clutch tool to remove the clutch assembly and glow igniter to start the engine and a flat screw driver to tune the needles.

A good alternative to a flywheel puller is a battery terminal puller from an auto parts shop. They're more adaptable than most flywheel pullers are and do the job just the same. Easier/cheaper as well.

Comments in red above.

I would add a bottle of good synth oil or castor to use as an assembly lube. Also if you have Novas, a flat head screwdriver that fits down the holes in the head and is big enough for a good grip is a must.

10mm 6 point deep well socket for clutch nuts.

Re the torque wrench, it's really helpful in getting the head to just the right torque. Before I got the torque wrench I was breaking in an engine and one screw popped out. After that I figured I should get one. I think it's better that all four screws are equally torqued. Then you don't get that situation where the head button is unequally torqued up and a screw might pop out.

ok so here are the tools I may order, just tell me if some of them aren't needed

springs


flywheel nut + plug


or this if it's enough?


what are the screwdriver sizes needed to tune the engine?

Whatever size fits! J/k it's going to be around 3/16" blade or so. You need to small enough that it will fit down the barrel of the high speed needle without scratching the inside. It also wants to be able to adjust the idle and low speed adjustments without being too wide that it hits the case. Best case is to pull your carb (or take your car) with you to the local hardware store and try out the individually packaged higher quality screwdrivers to find the one you like.

All the tools others mentioned and this sleeve puller

Do you really need a sleeve puller? I just stick a zip tie in the exhaust and rotate the flywheel to push it out until I can get a decent grip on it.

... or a piece of wood or any other semi-soft material.

I've never needed one but there has been a time or two when it would have come in handy.

Have seen some that will not budge with a zip tie or even several zip ties. The puller makes life so much easier. The right tools really make tear down and rebuilds go smooth. The top three I would get are the os plug wrench, hudy bearing puller and the sleeve puller. Hide the plug wrench and sleeve. Puller because they always end up in your buddies box when they go home.
