Good video. My 435 appears to leak oil when not in use so all my bar oil seems to drain from the reservoir. Using your detailed instructions I plan to take my apart to see what's up. Thanks for the vid.
Next time use an adjustable wrench down at the open end of the Bx Wrench to apply pressure as close as possible to the Clutch. This reduces side lean while breaking the clutch loose. Couple of notes: 1) The Nipple does nothing - the Seal is formed by pressure from the Metal Plate. If they get worn, Replace ASAP. 2) I think people do not realize, if trash builds up around the Pump gears Pressure from the spinning Pump Rod could turn the outer sleeve. This would cause a blocked oil path and push oil out around the outer Sleeve - drip, drip... If the rubber line is not worn through or Swollen and the Metal plate is applying proper pressure, it should not leak. However, excessive trash around the Pump and tail of the Chain will soak up a lot of oil and eventually leave a puddle under the saw.
Just a quick note, the 435 specs call for a 50:1 fuel:oil mix, and by the looks of that TruFuel bottle, that was 40:1 mix... more lubrication but will foul the plug faster. Really appreciated the tight shots of the chainsaw, many videos have a wider angle and it's a bit more difficult to see the details. Thanks!
It’s a very temporary fix. I’ve had the 435 for 12 years and have done this several times. It lasts about 6 months regardless of level of use. Mine has seen many, many, many hours of use. As has been mentioned before, keeping the area at the tail of the bar clean helps, but the new part does not last long. I store mine on its side (bar face up) to minimize leaks. verify oil mist from the bar tip occasionally during use. I thinks it’s a poor design, but the thing keeps chugging along so I use it for small stuff.
Thanks for feedback, I haven’t used mine a lot since I replaced it, It’s been holding so far, I have to keep an eye on it. But like you say it’s been a good saw for me otherwise.
No criticism intended - could you have spun the pump manually to check oil flow - before replacing the cover etc ? Appreciate any flow coming through would just be an indication but as you had concerns over the altered nipple pattern, perhaps it would have been prudent before reassembly ? Thanks for posting 🤙
You really should have cleaned the saw better. The roller bearing should definitely be cleaned well and then apply grease. All parts should have been cleaned and inspected for damage.
Good to hear. I have the same issue and am afraid to order a new $25 oil hose and get the one without the nipple and have it still leak. If the sun hits my saw in the garage and heats it up it leaves a huge puddle of oil. @@MeadowgateWorks
So how exactly was it leaking? I have the same chainsaw and mine leaks oil when it's not in use.. I had hoped that it had an oil shut off like my pole saw does..
