I'm installing a WOSP starter on the Speedster and thought I'd check with anyone here that's installed one; Do you have oil slingers on your flywheel, and did you have any problems or interference with the WOSP starter and the slingers? If so, how did you resolve it?

Here's a pic looking into the starter mounting hole - you can see the ring gear on the flywheel and the end of one of the slingers. Thought I'd also take the bendix cover off to get a better view. As always, thanks for any and all guidance/advice/wisdom you can share.

Hi Dave,
The Wasp starter has always got my attention & this seems to address some of my questions. Does the drive extend from the starter housing? (as
most starters of this style do or extend past the ring gear & retract into the ring gear?) If it retracts the only issue would be if the slinger collided
with the starter nose. If it extends into the ring gear shouldn't the ring gear be turned around so the beveled teeth on the ring would be engaged
with the starter gear or would the bevel on the ring gear be incorrect still? Or does it even matter???
I have seen the venders slingers collide with the stock starter housing. Sounds like a rod knock.

If the slinger is mounted on the front of the flywheel I would remove it to avoid a conflict. The flywheel doesn’t need to be reversed as some have suggested. The WOSP starter works great as designed with no modifications required to the flywheel. It has a tapered gear that engages with the flywheel when power is applied. I have used this starter for years and it works great!

Hello I have oil slingers and the Wosp starter. No problems.

I would say it depends on just what type of slingers you have. I would bet that yours would/could be a problem. I would trim back any portion of the slinger that overhangs the flywheel edge. The WOSP gear is certainly desgined to clear the flywheel, but anything more than that...?

Thanks guys, I appreciate the comments and advice.

Dennis - What type of slingers do you have? I have the ones I got from Texas T Parts in 2013. Here's another shot of the flywheel with the ring gear and slingers before re-assembly. (Not a great picture, but you can see the slingers) Also, here's a link to a short video of a bench test of the WOSP starter. Haven't seen a video of how the starter works, so here it is. The shaft and gear extend 5/8" from the starting point. I'll definitely remove the Bendix cover to get a better view of how the starter gear engages the ring gear.

I test fitted the starter with two gaskets (as recommended by frontyBoy in a post from May). Looks like the starter gear locates between the slingers and the ring gear, in the gap where the flywheel is laterally. I turned it over with the hand crank a dozen times and had no interference at all. Since the solenoid pushes the starter gear shaft toward the ring gear for engagement, then retracts back toward the starter, there shouldn't be any problem. Here's a pic (again, not great, but you can see where the starter gear resides.

I buttoned it up and just took a test drive. All good. Still need to complete the wiring on the starter, but it's installed and she ran fine.

Obviously the starter engages the flywheel from the front. It extends, engages and then spins - unlike the original Ford that is spinning when it engages the flywheel. I believe the WOSP is a lot easier on the flywheel. I have used a WOSP with great success for a couple of years now and recommend it to anyone. It is powerful and worry-free.

I have a new Japanese starter on my '14 roadster. Using 1 cork gasket for mounting there was a tiny bit of interference. I added a 2nd gasket on Steve Langs suggestion and problem solved. The issue was the very tip if the pinon gear did not release from the ring gear. Added the gasket problem solved.

I will say again That is the best bang for the buck. Why pay nearly the same price for a 100 year old designed starter when you can have a brand new design the really works every time.

just sayin'

My oil slingers are from Langs. Hope this helps.
