Tech Session
Report
by Dennis Trowbridge
Twelve people braved the bad roads caused by an early March snowstorm
to attend this yearšs Al Piemonte tech session. Once again Russ
Casolari obtained the use of the Piemonte service department for
the session. This year however we had to share the shop with a
large number of trucks and cars being worked on. The service department
is now open on Saturdays unlike in past years. We had a service
bay sandwiched between a 1954 end loader and a Corvette. John
MacLean and Dave Bralich led the session this year. They planned
on tearing down and rebuilding a four synchro MGB gearbox that
came out of Davešs š76 MGB. Most of the people attending had never
seen the insides of any gearbox before. All the gears, forks and
rods can be a scary sight for the first time. Ray Glorioso explained
how all the gears worked together to create the various gear ratios
used. Barney Gaylord explained the operation of the synchro rings
and how they helped the driver from grinding gears. Russ brought
along a broken ring so everyone could see what happens when you
jam a gear without your brain engaged first. As the gearbox was
disassembled the parts were examined for wear. Ray Glorioso had
a wonderful time with the parts washer cleaning everything as
it was removed. Not surprisingly, parts were worn and found to
be in need of replacement. The layshaft and rear bearing were
worn and had to be replaced as was the reverse gear that Dave
knew about. We didnšt have all these parts on hand so another
session will be held later to rebuild the gearbox. After everything
was cleaned up we adjourned to Portillošs on North Avenue for
lunch.
(Editoršs
note: Dave plans on reassembling the gearbox on Sunday, April
25th in his garage in Streamwood at 10:30am. Spectators are welcome.
