Nik's Poulan Thread

[Jethro 2t sniffer]

I have been trying to get my Poulan 4000 oil pump working. I posted my issues in a previous thread. I have installed a new diaphragm and gaskets, but now I have a starter pulley problem. In the picture below you can see the plastic is separating. It widens under the strain of pull starting and then binds in the housing and won't retract. Anyone have any suggestions on a fix for this, or do I need to search for another obsolete part?

Bugger is that on the 4000? Its a 3700 pulley by the look of it

Yeah, it's the one that was on there when I bought the saw on Craigslist. Maybe it was replaced at some point by one from a different model. It does look different than the one pictured in the 4000 service manual.

There was a couple 4000 pulleys on Ebay a we while back if you want to run a 3400 starter then the 3400 flywheel needs to be used also just from memory

Looks like a modified 3700 starter pulley. See if you can find the 4000 pulley

Grab it before I do haha

Glad you found one, I looked but no luck . Some out there still

 

[Jethro 2t sniffer]

Yea that's 3 I've seen so far in the last 2 or 3 months. 1 day someone mite find a simple enough conversion off a common saw I bet there's something. I'm thinking make up a drive plate with a nut in the centre off the flywheel and a hole in the housing for a drill if I really really get stuck in the future

Thanks for the ebay link Jethro, The part on that pulley that engages the flywheel pawls is different than the one on my saw. Do you think the ebay one is correct for my 4000 and will engage the flywheel properly? Also, I just went to the hardware store and got some Devcon plastic weld epoxy . I am trying to cement it back together with it. I don't know if it will work, but it's worth a try anyway.

 

[Jethro 2t sniffer]

Yes it will work just fine. If you dont want it I'll grab it for a spare if the shipping is reasonable. You may get away with epoxy but I'd grab that 1 on the bay if I were you while its there

Post a picture of the starter and flywheel, that what you got ain't no 4000 pulley that I've seen.

Good idea

 

[Delano1981]

You can kind of see it in the last picture I just posted. I don't know what make or model this pulley is but it worked on my 4000, at least until it started coming apart. I'll get a picture of the flywheel and post it.

 

[Jethro 2t sniffer]

Anyone have a 3700 pulley to look at?

 

[s sidewall]

Need a better picture of the pulley, not a side shot. Need to see the engagement side.

Someone has the complete starter assembly for a 4000 on eBay for 50, same as the 3700. 3400 pulley is all plastic, totally different.

Steve

 

[Jethro 2t sniffer]

Well his looks different to the 3700 type I'm finding I'm my searches.
