New battery in one mower. Took the TMAX over to get the batt this AM. One of the perks of a big scoot… putting a mower battery under the seat with room to spare. Replaced the stripped steering gear in the other.  Had to take the deck off for the steering repair and found some bad cracks in the belt and replaced it so maybe I’ve avoided taking the deck off again in the near future.  I got all but 1 coil for the Altima so I went to do the valve cover replacement.  All 4 spark plug tube seals were totally shot. Oil in all tubes.  The crankcase breather hose kinda fell apart when removing it to take the cover off. Got 1 from AutoZone and it was wrong. Looks like only available from Nissan so I’ll be checking the local dealer tomorrow. 4 new spark plugs in. Oil change whenever all the rest is done. Waiting on the valve cover gasket for one mower and then hopefully I can get all of this silly 4 wheeled work over. |

After that you will need some 2T time to recover. The temperature looks to be too high for those seals to make them fall apart like that. What would happen if you used a little aviation form-a-gasket on the seals and valve cover? Can you replace the seals individually? Can you get higher temp seals? The individual tooth loading is very high on those plate steel steering sector gear and a pinion gear. I have a similar problem but slightly lower tooth load on the rack and pinion steering on my craftsman mower. Crap designs that work for a while for our disposable civilization.
Reverse bends don't work very well on V-belt drives. Thin serpentine belts work better with reverse bends but that high debris environment would kill them also.

Can you replace the seals individually? Can you get higher temp seals? They made it 18 years and 175,000 miles before I finally had to do something about it so this isn't one worth re-engineering to me. If I had to guess, the Altima will be gone somewhere around 200,000 miles or 20 years. Private party value of the car is only about $2,000 and trade in is more like $500-750 so we're pretty much just using it till it gets to a point that we don't trust it or a repair is worth more than it is and then it'll go. The individual tooth loading is very high on those plate steel steering sector gear and a pinion gear. I have a similar problem but slightly lower tooth load on the rack and pinion steering on my craftsman mower. Crap designs that work for a while for our disposable civilization. This is why I want a zero turn. Every traditional mower that we've owned has had steering issues. Gotta keep a regular tractor to be able to do more of the ditches because they seem to handle angles that you shouldn't actually mow on better. Reverse bends don't work very well on V-belt drives. Thin serpentine belts work better with reverse bends but that high debris environment would kill them also. This one doesn't bother me. I don't have to replace the belt often. The older mower breaks belts much more. Probably not as good of a design and who knows how alignments may have changed with the thin deck and so many repairs for various parts breaking off of it. |

New door handle on the Nissan this morning. The last one broke when the door was iced over a year or two ago. Figured it was partially my fault. This one just snapped off with normal opening. Door panel, inner panel and window have to come out to get to the handle. Simple enough. Prob spent 15 minutes between a clip and an electrical connector that would be no big deal if not stuck all the way over where there's no easy access and my hands just don't work that well. Nothing makes 15 minutes feel like an eternity better than connectors, clips and fasteners in difficult to reach spots. Put that under a car or accompany it with needing to align something heavy to increase the fun factor greatly.
