Hello Chaps.

Planning on overhauling several smallframes engines and all

Can you recommend the tools that I need and those that can be done without

Looks like you can spend a fortune on factory style tools. I imagine some have come up with a method that doesn't require the tool

Some of the tools from Scooter Mercato here in the US:

-Crankshaft Installer and Extractor?
-Punch for dismantling wrist pin?
-Clutch Compressor
-Clutch Puller
-Punch for Flyside Bearing and Seal
-Best bearing extractor?
-Punch for Clutchside Bearing and Seal
-Case Separator tool
-Puch for Driveshaft
-Rear Axle Bearing Punch, Removal
-Wedge for Crankshaft
-Cush Gear Repair Tool
-Tool for Mounting Gear Selector
- Wrist Pin Puller Tool

Two very small hands. Then again, if the engines are out of the frames completely, it might go ok for you.

I love riding mine, but it's my least favorite to work on.

-Crankshaft Installer and Extractor?
I didn't find I needed it, gentle whacks with a rubber mallet were enough

-Punch for dismantling wrist pin?
not sure what this is but have built my engine without

-Clutch Compressor
yes you need it but can make one from home depot hardware if you are just doing a stock clutch and don't need to build it in the bike

-Clutch Puller
yes you need it

-Punch for Flyside Bearing and Seal
use a socket for a drift

-Best bearing extractor?
heat and a gentle whack of the case against wood for the small driveshaft bearing (sometimes an oven is useful, I used my barbecue!). otherwise use sockets or drifts to drift it out

-Punch for Clutchside Bearing and Seal
drifts / sockets

-Case Separator tool
no

-Puch for Driveshaft
I assume this means punch. If you install the backing plate, you won't push the bearing out as you seat the axle in the bearing on the hub side.

-Rear Axle Bearing Punch, Removal
drifts / sockets

-Wedge for Crankshaft
no

-Cush Gear Repair Tool
not sure what it is, but I didn't rebuild my cush on the smallie. on the P it didn't require any special tools

-Tool for Mounting Gear Selector
if this is the 2 blocks for the spring/ball installation, definitely yes

- Wrist Pin Puller Tool
yes

*** I forgot about the split bearing on the flywheel side. You'll want the drift to mount the race on the crank. I'm not sure which of the above is describing it. You can get the old one off with heat and a quick pry or you can use a dremel with cutting wheel to work most of the way through and then pry it apart.
