Left rear engine plate
Left-hand rear engine mounting plate, Triumph PN 82-4229 (also F4229), bolts the crankcase to the frame on the left side.
This is the left rear engine plate, Triumph part number 82-4229, also listed under the older F4229 designation. It shows up in the parts book under motor fittings and engine fittings and exhaust system figures, which puts it right where the engine bolts to the frame at the rear, on the left side of the machine.

Engine plates like this one are structural — they tie the crankcase to the frame rails and carry mounting points that other hardware, including exhaust brackets, can pick up from. The catalog record for this part spans a run of years from the mid-1960s into the mid-1970s across a dozen listings, which tells us it was a long-running number rather than a one-year-only piece, but it doesn't spell out which specific models used it in which years.
If you're replacing engine plates, it's worth checking the plate against your frame and crankcase mounting bosses before you commit, since these vary shop to shop in reproduction quality and hole placement. Give us a call if you want to confirm fitment before ordering.
