G5 Rebuild - HELP

Postby Trebor160 » Thu Jan 31, 2019 8:55 pm

Hi All - Ive stripped sown my G5, had all the parts powder coated and tank resprayed. Im now starting the rebuild. Done the suspension / dampers but cant find any exploded drawings or docs which clearly show how the bottom part of the frame is put together and how the engine is mounted. Can anyone help, I live near Manchester and if anyone has an G5 or an AJS model 8 I could have a look at and use as a reference for the rebuild I'd be extremely grateful. Any pointers as to whats the best order to start the re-build would be welcome.

I'm also looking for a couple of parts - the top triangular engine bracket that fastens the engine to the top bar of the frame, as mines gone walkabout and the bracket which is mounted on to the left hand front leg that that brake cable fastens on to as my bike came without! I'm struggling to find both on any online parts lists. If someone can come up with numbers I'll do the search on the spare parts sites, but I'm struggling at the moment to locate....

Cheers & Thanks in advance, Rob

Hi Rob there's pictures in the forum showing the frame - I posted some but can't find the originals!!

The triangular engine bracket is the head steady - unfortunately I don't have one. I don't think that they are available so its secondhand/used. Try AMC classic spares or Les at Russell Motors London.

The other part is available from the club spares.

044307 FRONT BRAKE TORQUE ARM L/WT 350 PLUS CSR

Brake Torque Arm L/wt 350 plus CSR

Price : £29.25 each Other currencies

Price incl. tax : £35.10 Other currencies

Stock : Available

The G5 & G2 have small but important differences especially around the frame and the way it hangs together!!

Check through the G5 postings all the info is here somewhere!!

Have fun

Steve

Hi

My restorations follow the same general lines:

Assemble the frame - centre stand - swinging arm - dampers - yokes.

Fit the engine / gearbox - forks - front mud guard.

Fit front wheel and lift the bike onto the centre stand - fit rear mudguard and wheel.

Electrics - secondary chain - chain guard - side stand - timing - handle bars - control cables

Remaining bodywork - exhaust - seat - fuel tank

Check over every nut and bolt - fuel - oil - test ride :)

Regards Mick

Not done a lot of this but I'd say identify the clearly "outside" work that you can't do and get that in process asap.

Ok thanks for all the good advice. Started to build up the botton part of the frame with all the levers , pegs, spacers etc. in the garage. Despite the cold actually enjoyed starting to put is all together. Probably finish off the lower frame tomorrow.

Next
