Topic: D17 timing Posted: 28 Jul 2010 at 8:48pm
Okay I'thousand chasing the gremlins in my D17. Dang thing just doesn't run shine. So I thought if I threw a timing light on it I might exist able to run into if the dist being worn was throwing the timing around.
The manual says expect for the timing marker in the hole on the RH side of the torque tube......okay. No pigsty. Do I demand to drill.........?
Idea at that place was a post previously that said to look in the bottom inspection hole but that doesn't seem right to me - seems pretty akward to do with a light. Dang manual show pics of every other dang part simply non the timing marker/pigsty.
Whats up with that?
Anyhow......assist anyone?
Cheers,

There is a movie of the pigsty on page 54 of the Gasoline D-17 department of the A-C service transmission.

I looked at the torque tube thingy again....I think my loader frame might exist covering information technology. Krap.
Shined the timing light at the front end pulley, the keyway shows upwards pretty klear. It does bounciness around a bit, only groovy. Seems like it is missing once and while though - similar every fifth or 6th fourth dimension around at idle seems like the light doesn't fire. Krap.

Yep, there definitely is play in the shaft, information technology has about .008" play which I retrieve is the max. That prob is contributing to the uneven running. Only information technology as well has other problems -
Carb icing - the carb trunk gets really cold at the manifold connection, frost shows up if its 50F or below. Not certain how I could ready that. Terminal nite I started it up and adapted the carb, she was running pretty good for 3 or 4 minutes, then it started to miss and the idle adjust spiral did absolutely zip. I could turn it all the way in and it made no departure.
Manifold studs - too noticed last nite one or more of the manifold studs is leaking a scrap of antifreeze. Only had the head done last fall, didn't think the studs went all the way into the water jacket. Could the caput be cracked?
Bottom end clunk - I'm hearing a soft clunking coming from the oil pan expanse at idle. Oil pressure is low after the engine warms up, this can't be good. I put new rod bearings in last fall only left the mains alone as the rods looked pretty new. I'k thinking the last guy that overhauled her did the same thing - peradventure the mains are tired. I've got to split it this fall and modify the rear seal, might besides do the mains every bit well. Hopefully that volition set up the low oil pressure and clunking trouble.

Unless the old ones accept been drilled out and they were drilled style too deep and into the water jacket. Have you pulled out the spark plugs and looked for antifreeze on the plugs?? If you say information technology runs keen with a cool engine only runs bad when the engine warms up information technology might exist a head gasket? Also antifreeze in the oil tin ruin a brand new fix of bearings in no time. I would look closely at it.

Never thought about the throttle shaft - I'll pull the carb and see how much clearance there is effectually the shaft. Might exist my prob - it has been pretty humid this summertime. I put a carb kit in a coupla years ago, but prob won't hurt to have information technology apart and clean it up again anyhow.
No antifreeze in the oil or cylinder - plugs expect skilful and the oil is prissy and clear.
Cheers guys I appreciate information technology, came in last nite from working on the old girl and told the wife it might exist time to look for an apartment in town.....
cheers,
