Looking for the part number for the oil pump driver. To run a rim sprocket set up have the drum and bearing. A 346 oil pump driver will not work the crank shaft is smaller on the 350. Have looked around at some parts list to no avail.

#503 89 21 02 oil pump drive gear

Google search brought up this conversion drum from Bailey's. The oil pump part number is from middle of the description.
-
The only other worm listed is the 503 93 18 01
I don't own a 350 anymore but my 346XP has the big rim 7 tooth regular 3/8" And uses the original worm gear that was for the small rim.
I left the spur type drum on my 350 and never changed it.
-
The original worm IIRC is driven by the ends of the spur teeth. There's a imprint in the end of the nylon gear.
The gear number quoted in the Bailey's link is the same as the number for a 350 with a spur sprocket in the Husqvarna IPL.
My 346 gear is driven by the end of the rim drive teeth of the clutch bell?
When I changed my 346 to use a 357XP clutch bell with the bigger rim, the rim drive teeth on the bell are larger in diameter but the 346XP seems to oil just fine.
-
The 503 89 21-02 gear is the same one listed for the 346XP New Edition
-
The 357XP uses . . .
503 91 27-02 (.325x7)
503 91 29-02 ( 3/8"x7)
I think this is because of the larger diameter of the rim drive teeth for the larger rim
-
There is a difference in the drum teeth from a spur sproket to a rim sprocket. Have the 346 oil driver and drum. It will not match up to run with the 350 oil driver. The rim kit above looks to have the right teeth to drive the oil driver that is on the 350. Will have to give it a try and see what happens.
-
The IPL for the 350 and the 346XP new edition both list this as the only number for the gear for the spur and rim bells . . . #503 89 21-02
-
Sorry, looking again I see the #i gave for 346, 351, 353...has been a long week. ::)

I notised that - but now you answered my question before I asked it..... ;D
-
The oil drive gear is the same for the 346XP with a rim clutch bell as it is for the 350 with a spur sprocket.
The hub of the clutch bell/drum presses tight up against the oil drive gear and imprints itself into the nylon of the gear flange.
-
I have the sprocket above on order. Have done a little more research and found that the rim sprocket kit will work with the driver I have you just have to do as 660 has stated above. Will know for sure next week when I get the kit installed.
-
Something's not right in those IPL's. The metal cased saws use an oil gear that has a different depth than those for the plastic case 350/2150. I can check when I get to the store on Tues. for more info.
And the 345/340/2141/2145 use yet another gear. (which is still used on the 445/450/2245/2250)
-
I had a 2007 350 for about 4 years but never had the clutch off.

......
The IPLs I looks up show 3 different oil gears:
346xp/353 with rim, 503 89 21-02
353 with spur, 503 89 20-02
350 with spur, 503 89 22-02
What is missing is a gear for a rim setup on the 350, and it would not really be logic if one of the listed ones also fits that use?
The oil drive gear is the same for the 346XP with a rim clutch bell as it is for the 350 with a spur sprocket.
The hub of the clutch bell/drum presses tight up against the oil drive gear and imprints itself into the nylon of the gear flange.
I can't find any IPLs that tell me that?

The 345 and 350 are in the heading there, but are not mentioned in the text. I wouldn't trust that heading....
-
The best I can tell is the drums are the same for the 350 and 346. The drive sprocket bearings also appear the same the only difference I can see is the oil driver. The hole for the crankshaft is larger on the 346 and smaller for the 350.

I would appreciate that. Thanks for the offer.

Yes, that is not the correct part #. When I looked initially it looked like it was but the text below the description does not say it fits the 350.
-
The 345 gear is 503 93 18 01
-
Used my 350 pump driver and installed the Oregon rim sprocket kit 108215X for a 346xp seems to fit good. It just slides together will let you know how it does tomorrow. But I think it is going to work just fine. I can spin the drum and watch the driver spin.

Good report
-
All works and works well. Thanks for the time and help from you guys.
