下置物箱打開後，右下方即可看到卡榫

一隻手就可以解開卡榫

上面的卡榫要用力推開

UP左右兩邊的卡榫拉開就可看到室內濾網

才2年舊的濾網居然這麼髒!

換在Advance Auto買的濾網

裝上就收工

20200315-clean ac evaporator with an endoscope

開空調有異味，在不大拆儀表板的前提下，應該只有用內視鏡清洗蒸發器一途。

首先，將star bit固定在wrench

鼓風機下方底殼疑似有不明黴班，用清潔劑刷洗和陽光殺菌

上方圖片共有8顆螺絲要鬆開，中間那2顆是在鼓風機取下之後才需要拆

刷洗過後，陽光晾乾

內視鏡綁清潔劑注入軟管

內視鏡連軟管從鼓風機管路伸到蒸發器，然後把一整瓶清潔劑噴光，然後我又加Lysol殺菌

從AMAZON買附接頭的清潔劑

開暖氣吹乾，同時我再以空壓機送風加速吹乾

最後將鼓風機裝回去，試車確定沒錯誤燈號，完工。

20200111-Restore wheel rim for 2009 Mercedes E350 and NYS inspection

又該2009 Mercedes E350做NYS年度車檢的時候，我自知車況OK要過車檢沒問題，但是車廠一定會針對雨刷和輪胎來囉嗦(a.k.a勒索)，坦白說右後輪胎的確有變型的狀況，所以不勞對方動口，乾脆先自行了斷，我先更換雨刷，也從網上訂了2顆245/40ZR-18輪胎把後面兩輪全換，其中原後乘客座輪圈邊緣凹陷輕微變形導致容易消風漏氣。還好我有一個full size的備用輪圈，無奈狀況不佳，所以我得事先修復備用輪圈並上漆，用它替換原來的乘客座輪圈，如此一來車廠自然無話可說，車檢當然一次順利過關。本篇主要是記錄輪圈修復。

用Bondo Metal Reinforced Filler, 90451先修補如上圖小缺角，兼用100-220-600號的砂紙來回研磨，這是最花時間的

上底漆 (Bondo Gray Filler Primer, 00720)

上銀漆

這部分含AMG字樣原凹了一大痕，又是不規則的形狀，很難補，所以乾脆連同AMG字樣都補平。

連內面都上有耐高溫的透明保護漆

載去給車廠換胎然後再驗車

這角度看起來還蠻有質感的

20180715-DIY Tire/Wheel Lifter

One of the hazards for a DIY car mechanic like me is hurting the lower back or shoulders by lifting wheels/tires.
Unfortunately I have to deal with that quite often when I work with brakes/rotate tires/ change snow tires for multiple cars...
Thus, I hope to find a cheap tire lifter but Commercial Tire/Wheel Lifter usually cost $1500+ which is way above my budget. So, I decide to build one myself.

Revision: actually a Hydraulic Table Cart + a pair of rubber wheel chock may be an easier but even better (versatile) alternative solution. See illustrations in the bottom.

Mover's Dolly+Scissor Lift Jiffy Jack is my basic concept.

Actually this bike Scissor Floor Jack Lift hoists Center Stand is almost perfect except it is a little bit high for me. Because most time i use a floor jack on the drive way, the minimum height should be as low as possible.

I decide to go for the lower profile version of bike Center Scissor Lift Jack Hoist Stand $80

plus roller bracket $25 x 2

Piece them together with some 2" hex bolts and nuts, then Ta ta... Here it is

Testing

Spin the tire easily

essily move to position ( the minimum height)

Rise to catch the tire securely and so nice to my back!

alternative replacement: Hydraulic Table Cart+ 2 wheel chocks

plus

If you put a pair of wheel chocks on the table, you will have the similar functions of the wheel lifter. Unfortunately, a higher clearance from the flat ground is required. That is the catch!

This combination may cost around $200 (500LB capacity)-$300(1000 LB capacity) but the Hydraulic Table Cart alone will help you to achieve more.
