ROD BEARINGS 650/750 .020
Connecting rod bearing set, .020 in. undersize, for 650/750 Triumph twins.
This is a set of connecting rod bearings for the 650 and 750 Triumph twins, ground .020 in. undersize to suit a crankshaft that's been reground that amount. The catalog lists it as 70-3586/020LFH, also cross-referenced under 99-7042 or 99 7042 in some parts books.

Undersize rod bearings like this one are used when the original journals have worn enough to need machining back to true, and the .020 marking tells you how much material has already been taken off the crank pins. If you're rebuilding a bottom end and your crank has been reground, check the actual measured undersize against what's stamped or noted on your crank before ordering, since fitting the wrong undersize bearing will leave you with the wrong clearance.
We don't have more detail on this one beyond the description and the alternate part numbers. If you're not sure whether your engine takes the .020 size, bring in your crank measurements or give us a call and we'll help you sort out the right bearing.
