Top of pagePrevious messageNext messageBottom of page Link to this message  By Allan Clark on Monday, August 29, 2016 - 05:43 pm:

recent assembly of T engine turned over on starter about a month ago and hand cranked to set valve timing / adjustment etc. went to crank it the other day and only got a 1/4 turn and it wont turn any further. removed Bendix cover and starter not jammed and was able to back up ring gear with a pry bar. hand cranked again still no go

what do you fellows think is the problem..

Did you put the oil pan inspection cover (underneath) on after setting the valves? Maybe a bolt is too long and the crank is hitting it. Try the bolt in the middle at the rear first.

Allan - I had an alternator seize up causing the engine to be "jammed". An easy thing to check before digging deeper.

Did you drive it in the rain and let water set in the spark plug holes which then drained into the cylinder?

Is the engine all together, with the head on & coolant in it?

Can you push the car in neutral? It is possible that the high speed clutch has stuck. Try jacking up one or both rear wheels and then with the parking brake in the neutral position try starting the engine. If it starts and the wheels are turning, you will know that the clutch is stuck. If so try working the pedals and maybe it will unstick.

Norm i think you might be onto it. I put in a new set of the jackrabbit clutch plates and have yet to set the clutch lever, handbrake bit.perhaps the oil has frozen the plates?

If the starter is jammed put the car in high gears and rock it
