Have been a lurker for a while and figured its time to get in on the action and get some advise from those in the know.
I am looking for some advice on the specialty tools for overhauling a Tonti Big Block motor/gearbox and diff. I have the (mis?)fortune of having a number of Guzzis that need attention and am looking at purchasing a good set of tools to complete all the bikes over the next few years as time permits.
I have recently completed a nut and bolt restoration of an original Blue 850 LeMans my father bought new from the factory in 1977, however due to the sentimental value and relative newness to guzzi motors I farmed out the Motor/Gearbox rebuild to someone more experienced
There a quite a few tools I know are basically mandatory, eg the two special deep sockets for the gearbox crank nut, clutch compressor & rear main seal tool, but am wondering how critical some of the other tools are (nice to haves or critical to success).
I am aware of the kit that is offered by Rolf Johansen in Norway, but unfortunately most of his kit is now unavailable, so am also keen to hear peoples experience of quality from other suppliers (stein-Dinse, MG cycle, etc)
The list I have compiled so-far is
Critical tools to have (I think)
18927651 - Crankshaft Ring Nut tool
14912603 - Clutch hub ring nut tool for 5 speeds
12911801 - Flywheel ring gear holding tool
??? Alternator Rotor removal bolt
Tools Iím not sure if are critical/just make life a whole lot easier/will never be used
14927100 - Rear main seal installation tool Ė critical or just makes life a whole lot easier?
30906511 - Cutch plate alignment tool
12907100 - Transmission output shaft holding tool
14905400 - transmission layshaft tool
14927300 - Camshaft Holding Tool
30912810 - clutch hub holding tool
#?? - rear main bearing puller
would prefer not to buy tools I will never use, but keen to hear from others that have completed rebuilds
