Mityvac

[Welder56]

looking at getting some tools for Christmas. After reading a few threads and posts it seems like quite a few people like the mityvac for pressure/vacuum testers. They seem very fair priced. I know my stihl dealer will sell me the stihl pressure/ vacuum tester but it's big bucks. But on the plus side of the stihl one it comes with all the different attachments.

Here's a few questions I have about some good tools to get:

What model of mityvac do most people here get?
Do a lot of you use the stihl seal puller? I'm hesitant to pry the seal out so I'm thinking this might be a good investment for my future rebuilds. Would it be worth the money???

Also I plan on buying a heat gun to install the bearings(thanks to mastermind's thread). Does anybody use a temp stick to get right temps or just wing it? I thought it might be a good idea to get a 250 degree temp stick to make sure i don't under/over heat anything. I've been reading my service Manual every night to get a really good idea how to tackle my next project (I've never done seals/bearings or split a case). I wanna make sure I have all the right tools and parts on hand. Am I missing anything?

I'm pretty handy when it comes to making good jigs/tools. So I plan on maybe buying the stihl piston stop and maybe reverse engineering it to do another contest in the next few months.

Thanks in advance

I have the Craftsman Pro version of the mighty vac. You can use points and other discounts 2 Sears. As far as a heat gun I don't think you can heat up the parts enough to worry about it. The Stihl puller nice but pricey, Lisle makes a small shaft in puller for reasonable price. I just use a screw or screw driver. OEM tools are nice but are not always practical for home owners and hobbyist. You maybe able to find another member in your area that can loan or do some cost sharing with you.

Carquest has the mityvac for around 75.00 MV8500 so that is not a bad deal. As afar as the puller I don't know.

I don't think many people use the puller, I didn't when I changed the clutch side seal on an 066. As far as the mityvac goes, I picked mine up from Harbor Freight. Juts be aware some models will only pull a vacuum....not all will do both pressure and vacuum testing.

Thanks for the replys i did realize there were models without the dual purpose. I guess I meant to say more specifically if there was a model that's a "must have"?

I know you can modify a screwdriver for seal pulling. Is this a more common tool for the job? Could anybody post a pic of theirs ( not trying to be a super lazy SOB as I'm sure there's a lot of posts about it)?

The model I got off amazon came with a nice case and 30 ish connectors of various sizes. Pretty awesome because I can test all different sizes of hose and fittings.

I was not happy with the mighty vac I would step up a notch to a better tool.

The mityvac MV 8500 is a perfect tool for vac-press tests , the stihl seal puller is another perfect tool that i highly recoment you can pull out seals from all kind of saws and other machines, even from other like husqvarna, dolmar e.t.c without to be afraid if make scratches to crankase. you will pull out seals with closed eyes. the part.number is 5910 890 4400. Also i recoment the crankase puller its another good tool that you can open and close the case with the same without headace . part.number is 5910 007 2222 . and some photos

About how much do the 2 Stihl tools cost?

 

[rich450es]

over $100 for the splitter
http://www.ebay.com/itm/Genuine-Sti...hainsaw_Parts_Accessories&hash=item35d3fcaaf0

and over $265 for the seal puller
http://www.ebay.com/itm/New-Stihl-T...584?pt=LH_DefaultDomain_0&hash=item4ade6f1c40
waaaaay too much money for what a heat gun and a modded screwdriver or sheetrock screw can do

you are corect for the splitter but the seal puller cost about 142 euros from the same shop. i agree with the heat gun but i dont agree too much for the screwdriver

The clutch side seal of most saws, is usually the easiest to pull in my experience.

I bought the seal puller (Stihl tool). I read every thread years ago on seal pulling. I have two saws in my shop now that someone tried to pry the flywheel side seals from. One of the case halves is pretty much ruined. Hopefully the person who removed the seal from this saw did not go on -- destroying seal pockets with their wreckless tactics. With that being said, I know there are many ways to pull the seals. Some are fond of the "drill a tiny hole and insert a screw" there are some potential problems with that (1) the possibility of chips in the case (2) Scarring a bearing or race -- or both.

Many here use a screwdriver notched out. I say "have at it". Every time I pull seals, I just keep smiling. It takes me longer to get the tool out than it does to pull the seals
As for the heat gun, I have one but I found using the oven heats the cases in a fraction of the time. I bought my Mity Vac off Amazon, at the time it was priced the cheapest
with free shipping (no tax). The case splitter I have was machined by a friend. It's made from .375 plate and works like a charm. You'll have to chart you own course as far
as what you decide to do. The guys here are great though, lots of information, lots of help. It's all GOOD!

I agree absolutely with you my friend, i have all the stihl and husqvarna tools even the MDG1, for stihls and the DIAGNOSTIC for huskys, i have try all theese **** methods with screwdrivers, hooks, drills and in most of cases the results are headace and scratches that cost much more of a tool.
My opinion is that is better to go to a shop with the corect tools and pay a little for pulling the seals out and dont try to make magics that cost you a new crankase
