Please share your tips on fitting a jacket

[runzwithsizorz]

Oil, and grease aren't working for me. It's *really close* to sliding on but no luck so far. Would heating the jacket, and/or the o-ring help? Thinking of using a cut-off wheel, or maybe folded sand paper and by hand sanding the groove slightly deeper.

Dish soap and a kind of a twisting motion...and perseverance!

Are you using this jacket on a tp motor or leopard? I wanna say the tp motors run .5mm smaller so the jacket may be .5mm smaller too. You could use a sanding drum on a Dremel

Perseverance I got. What makes dish soap better than oil, or grease? Hmmm, "a kind of a twisting motion", gotta try that cuz so far a wooden block, a large rubber mallet, crying, whining, gnashing of teeth, and using the Lords name in vain hasn't worked well for me. BTW, this ain't my first rodeo, but who upped it to a 16 second ride?

It is my first TP motor. I am using Stevens HRC jacket for it, like I said it is really close to fitting, but just too snug, maybe 1mm tops. A sanding drum on what? The o-ring????

I've rounded off the corners of endbells by sanding them before to avoid cutting Orings when fitting. If using grease or oil make sure it is silicone based, as petrolium based products will swell and soften many Orings.

Wasn't there a post about the new TP motors being 0.3mm larger diameter than the old ones? Perhaps 40mm motor, 37.7mm jacket?

EDIT: this is the post I was referring to: New TP motor design

Success! I got Stevens HRC jacket to fit. No easy task for I tore up the o-rings on my first attempt. Should have listened to NativePauls' advise to sand, and smooth the edges of the motor. Ordered 6 new rings from
Steven just to be sure. Still, I could tell there was no way this jacket would fit. What I did was mount 2 cut-off wheels on my dremel, the aprox. width of the o-ring. I then deepened the the o-ring groove.
Bottom line here is, with some mods, and effort, the HRC jacket will work, whereas the TP jacket will NEVER work.

Just saw your post. Sorry you are having problems with the jacket. If you don’t mind me asking what TP motor and jacket do you have? I want to check my tooling setup. The test TP 4060 motor I have measures 1.558” – 39.573 mm can OD. I try to give a +/- fit of .002” - .003” for slight variations from motor to motor that I have found to be normal.
Motor manufactures do make slight changes some times without notice. If I made a mistake of cutting the groove to shallow my apologies.

Good Morning Dave, The TP motor I have, and that I ordered from them, because OSC did not have THAT KV,(1180) in stock, and in fact, OSC hardly had any TP motors at that time, (OCT. 17), was a 5670. TP, also did not have that wind in stock, and told me it would arrive in about 2 weeks, ---- it was 7 weeks. The free jacket arrived 4 weeks later. See this thread here for my thoughts on it; http://forums.offshoreelectrics.com/...p?56417-Motors My TP motor is 55.81mm, sorry I do not have a better mic. Without adding much pressure I went around the groove with my dremel 4, or 5 times, and I dare say I probably deepened the groove more than .003", more like .011" . It was still rather snug, but bearable to fit it, and yes, I have run pressure checks. I do wish your jacket for this motor was a bit longer, for the * usable * length of the can is 85mm+, though I am sure it is fine. Your jackets are on my Neu 1515, and 1527 and they cover much more of the can. It may even be one of your jackets on my monster Fuego 580xl, -- nah, you can't possibly be that old.
Your concern for your products is duly noted sir, and rest assured I will continue to buy, and recommend HRC!
Kindest Regards, to you and yours, Todd

Thank you Todd. Oh boy there is the problem. The TP 56 mm HRC jackets OSE has are for motors that are 55 mm diameter. I heard TP was going to make changes but no indication of when. A friend with our local club ordered the 56 mm motor that was delivered to him a couple weeks ago that was still the 55 mm size. It drives me crazy sometimes trying to keep up with the changes. Looks like more changes are to be made here on my end. I will get with Steven on this and come up with a plan.
We do have a 70 mm long jacket Steven carries as well. 580XL..lol yes Sir I remember those, still have one that has never been used.

Perhaps your friend brought something from stock(?) Regardless, it is apparent changes have been made recently to at least the 56mm motor dimensions. Here is a pic taken today of your 70mm jacket on the 5670 TP motor. P1030305.jpgAs you can see, your jackets cover more of the 1527, 1515, and 580xl motors. And yeah, you and I go back a long way, but I have never said anything till now, NOT against you, but to simply praise you. sorry my bad.

Todd, please don’t misunderstand me, I greatly appreciate you bringing this to the forefront. Better to find out now than having a bunch of jackets that will not fit the new motors. Yes Sir that motor could use a longer jacket. Does the new motor still have 6 mounting screws or did they change that as well? Thanks.

Notice the shiny outer line around the can? That is where our friend across the pond, (NativePaul) recommended I smooth the sharp leading edges, and he was right. P1030306.jpg
