Eddie Trickett Posted May 22, 2020 Report Share Posted May 22, 2020 Gearbox now installed and tried turning engine by hand with large spanner on crank bolt. The engine is locked and won't turn. Gearbox definitely in neutral. Slacked off the starter bolts and engine turns. Re-tightened them and it locks up. I can't see what would cause this. Any had a similar experience or any idea what could be catching. The starter is new with separate solenoid. Thanks Eddie Quote Link to post Share on other sites
Lebro Posted May 22, 2020 Report Share Posted May 22, 2020 (edited) Check that the starter motor has the correct number of teeth to suit your flywheel / ring gear. Bob. Edited May 22, 2020 by Lebro Quote Link to post Share on other sites
stuart Posted May 22, 2020 Report Share Posted May 22, 2020 (edited) Or it needs spacer and or a shim between it and the bell housing. Items 89 or 90 here https://www.moss-europe.co.uk/shop-by-model/triumph/tr5-6/electrical-system/starting-system/starter-motor-tr5-6-1967-76.html Stuart.

Eddie Trickett Posted May 22, 2020 Author Report Share Posted May 22, 2020 Stuart, I think you are right. However I didn't know that these existed so I filed a fraction of a mm off the centre boss on the starter endplate and all is well. The starter turns the engine so on to the next job. Bob, I checked the teeth against the old starter and the number is OK. Many thanks Eddie Quote Link to post Share on other sites
