starter drive tea 20

[stsew]

Having trouble finding a starter drive (pinion) for my tractor. The tractor is a Tea 20. Lucas starter, 12 volt m35g-1 v163 20538a. the drive is 10 tooth although I've been told I could use a 9 tooth? Any suggestions? Thanks

I have used 9 tooth starters before on three occasions on different tractors TED , and TEA varieties . All worked satisfactorily with no trouble with meshing or ring gear wear .

Shown here is an original Lucas made in 1953 and an aftermarket replacement [ in black ] from about 1999.

I would try to repair the original if you can , some spares including pinions are available from Triumph and Vanguard spare parts sellers in the UK , Ritters is one that comes to mind .
The originals are far superior in build and reliability .

Sorry that should have been Rimmer's rather than Ritter's .

You might try your local independent auto parts store; they won't sell the drive, but may be able to send your starter out for rebuild.

Also, I think you may have copied the part number wrong. I think it should be 25038A rather than 20538A. Unfortunately, my Lucas catalog doesn't list either one (it's for cars) but all of the M35G models fall between 25000 and 25075. My Ferguson parts catalog also lists 25038 for TEA20 with 85mm engine.

My mistake. The correct number is 25038A. Haven't found one yet but waiting for replies from suppliers. Thanks for the help.
