• Husqvarna Motorcycles Made In Sweden - About 1988 and older

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

What Size Motoplat Puller Do I Need?

Husqvarna
AA Class
1976 175 GP. 116mm Motoplat WITH THE LIGHTING COIL.

Per the workshop manual it looks like the 116mm Motoplat WITH the light coil is the same puller used for the larger 139mm Motoplat.

Lots of diameter and thread pitch combinations on eBay. Anyone know the specific puller I need?

Thanks again. Binx
 
Visiteur & Michel - Je vous remercie pour vos réponses.

From your second post, visiteur, I gather that the 22 x 1.5 is NOT the correct puller for my Motoplat, because the Husky Workshop Manual says the 116mm WITH LIGHT COIL uses the same puller as the 139mm flywheel.

What size puller is required to remove the 139mm flywheel?
 
On 81-83 motoplat or SEM with a 116 mm flywheel you must take a male puller 26 mm right hand thread 150.
On my 390 -80 with a 139 mm motoplat I must use a male puller 33 mm right hand thread 150.

So don't know exactly what puller you need for your 175 1976 !
Try to measure the inner diam of your flywheel. Don't forget to add the place for screwing.

Best is to ask an expert :

I had a 1976 175CC with the Motoplat about 15 years ago... I don't remember anymore what diameter the Motoplat was... I think it did have a lighting coil but not 100% sure. The "standard" 26mm x 1.5 Motoplat puller was too small and 33 was way too big. Could not find a puller anywhere. (Internet was not that useful back then) I carefully measured and ended up making a puller on my mini-lathe out of a suspension bolt off a diesel truck.

My 175 Motoplat had a 27mm x 1.25 RH thread. (I know because I still have the puller I made and the notes I used to make it... only tool I was ever able to successfully thread on a lathe! LOL)

Keep in mind that when measuring the ID of the flywheel it will be smaller than the puller size you need... my notes say that my 175 Motoplat had an ID on the threads of about 25.7 mm. That's the "minor diameter" of the threads and NOT the puller size. The puller threads are measured by the outside ("major") diameter of the threads which I probably looked up in Machinery's Handbook and came up with 27 mm. Measured the pitch with a thread pitch gage. It worked! :)

Hope this helps.

PFW - I examined my threads for an hour or more, and measured everything as best I could. Based on a (slightly) educated guess I took a chance and ordered a 26mm x 1.5 right-hand puller. (I did this before I saw your post.)

UPS guy delivered my puller a couple days later and it was a Class A fit. Threaded in like butter. Popped the Motoplat no sweat.

I have no doubt yours was a 27mm x 1.25. Mine, thankfully was 26 x 1.5, which I was able to find on eBay. And that's a good thing 'cause I don't even know what a lathe looks like. Well, I do kinda know what a lathe looks like, but you get my drift.

Now that the Motoplat is off I find I have a much bigger challenge: can't get my cases to separate.

Binx,

Didn't mean to imply that you had to make your own! LOL There's a ton these days on ebay... but back then I couldn't find one for sale. And I guess I'm still proud of the fact that I was able to make one! LOL

I see that Michel posted up a link that says 27 x 1.25 fits the "early Motoplat". The 175 I had could have had the original Motoplat replaced as the previous owner was having a lot of trouble getting it started and it would not idle. (I found a plugged pilot jet even though the previous owner had said he had the carb recently cleaned... started and ran fine after I cleaned the carb again.) I also got a "spare" Motoplat with the bike so in retrospect that might have been the original. (The "spare" flywheel was 26 x 1.5).

Wish I still had it... I really liked that 175!

Anyway, great news on getting your Motoplat off and good luck with splitting the cases! (I know this sounds obvious but every time I've struggled with case splitting it's been a missed bolt someplace... On one of the old Huskys I had I think there was a single bolt that went in from the opposite side from all the other bolts that I missed and wasn't shown in the manual I had. But that wasn't the 175. Never had to split the 175 cases... and maybe it wasn't even a Husky... it was a long time ago and my memory kinda blurs things these days... LOL)
