    Seized broken aluminum starter bushing.

    Thanks, yes I used a small die grinder and did as you suggested but on 2 sides, worked like a treat. I used a sliding hammer to ram it out.

    Seized broken aluminum starter bushing.

    Thought of using an old tap and twist it to try break free but not put room. I can’t post photos from phone. Files too large. Will do so when get home.

    Seized broken aluminum starter bushing.

    Afternoon all. Have a Yamaha jet ski that came in that needed the starter replaced. As can be seen in the photo of the two starters, the bushing snapped off on removal. Seems salt water got to and is seized in place. Have used a sliding hammer and mandrel to no avail. (My knuckles are sore and...

    Free hobbing - a rogue method for spur gears

    Robin, Good to see a fellow country man here. When you get bored of playing around and need any precision gear cutting done, see Dave at Jmann Transmission or Emanual at Paddock Gears. Both in workington, Hre. PM if you need contacts. Sent from my iPhone using Tapatalk

    OTish: What kind of clamp to quickly seal the mouth of a sack vs a chute?

    We operate a hammer mill for stock feed. How quick is the bag filled? What's the cycle time? Clamping the neck of the bag airtight so no dust escapes, is it important or not. Have you a cyclone attached to the mill for the dust removal? On the feed output side the chute splits in 2 with a flap...

    OT: Standing to work versus sitting to work!

    It drives me crazy my workshop gang constantly put work on the ground versus using the 3 workbenches and welding table. Guess it comes natural as squatting around a fire for warmth, chatting, cooking and eating since they were born. Pretty sure its the way with most other 3rd world countries.

    NOGA Indicator Base

    I bought my Noga like this one a nearly 4 years ago and very happy with the arm and base, however the indicator that came with it has started to get a sticky needle after about 15 mths, switched out to a starrett indicator. The fine adjust on the head has recently got loose and doesn't hold the...

    Understanding wheel bearing and hub design?

    Thanks Limy. This is basically the set up I have been seeing. So on the harrow with the bearing 1” apart there is not much turning as the gangs are fixed in place and are running straight hence the closeness. Doug will search for that book online. Maybe it has a formula. What would be the...

    What methods to repair wear groove on crankshaft seal journal.

    Thanks all for the inputs. I learnt something new this week. Milland, I never knew there was such a thing called speedy sleeve. Called the SKF main branch and they had 2 sizes only, neither one was what I was after. They don’t sell them very often, in fact none in over 2 yrs.! Will have to...

    What methods to repair wear groove on crankshaft seal journal.

    OT - Sizing a water well submersible pump

    Afternoon, To play it safe, stick with what the original scheme design called for. However the new wet ends are a lot more efficient than 23 years ago, so you can downgrade the motor to 1 hp and still keep the same output your system was designed for by changing the wet ends. I used to run a...
