RUBBER SHIFT BOOT PLUS

RUBBER SHIFT BOOT PLUS

Shaped aluminum pie pan to fit around turret and fell gap between tread and surrounding transmission tunnel, secured in place with Scotch super 33 plus electrical tape that can withstand the heat generated in that areaģ. Cut out the aluminum pie pan to cover the large gap between the turret and transmission tunnel. This is a picture I took when I did the Miata.Ģ. After rebuilding the shifter and tightening down the lower rubber shift boot, I applied generous amount of shin-etsu Grease to the outside of the rubber boot, to moisturize the rubber and provide protection from drying up.Īpplied shin-etsu grease to the outside of the lower rubber shift boot, inside and outside of the upper shift boot. Scotch Super 33+ electrical tape from Home Depotġ. Sharp utility scissors to cut ceramic fiberĦ. Ceramic fiber insulation 1/8 in thick, purchase from eBay. Circular aluminum pie pans, got an extra one in case I messed up the initial slicingĢ. Protective blankets, curtains, covers, pads and wrappingġ. High temperature insulation seals and gaskets Lightweight, low thermal conductivity, high temperature stability, excellent handling strength, low heat storage, thermal shock resistant, fire and flame proof, chemical resistant, compatible with most corrosive chemicals, commonly used acid and alkali (exceptions are hydrofluoric, phosphoric acids and concentrated alkalis).Ĭhemical Composition: Al2O3 + SiO2 >97% ( Al2O3 47%) Fe2O3< 1% Commonly used Ceramic Fiber products include cloth, tape, rope, braid, tubing, paper, blanket, etc. The fiber is white and odorless, suitable for high temperature applications up to 2300☏. Ceramic Fiber is produced from high purity aluminosilicate material through strictly controlled high temperature furnace melting and fiberizing process. Unbelievable how much smoother and easier to shift after the rebuild! Should have done it sooner. I plan to keep my NA for a long time - unless shifter gets crunchy in the future, I don't plan to open it up again Also, it was easy to shape since it's like cutting thick foam or blanket, with a decent pair of scissors.

I chose ceramic fiber given its properties that I pasted below from a website for others to read. I started going down the thought of heat insulation for furnace and fire ovens!

Essentially, the rubber shift boot is at the mercy of the constant heat generated through the transmission tunnel and from the outside elements. Reading about how quickly they deteriorate, I sought out a way to insulate the boot from the heat along the transmission tunnel. Thanks to all the information here, I rebuilt the shifter on my NA Miata. Note: This component is designed to fit all years 1990 - 2005 Replaces both Mazda Part Number M513-17-480A and M514-17-480A' Its a good idea to change this component at clutch intervals. Small shift boot at base of shift lever otherwise known as the shifter turret.The factory shift boots are usually become torn with 60,000 miles and leak oil on the transmission and then the floor until the turret became dry up with the use of newer speciailly formulated rubbers these turret seals should last well beyond to protect you shifter mechanism. 'Our Shifter Dust Boot its all Mazda Miata MX-5 Fits 1990-2005 I wonder how the the longevity of the NC lower boot, Small Shifter Dust Boot - Mazda (R501-17-47Z), compares to the NA version and the rspeed version. Their underside insulation is heat resistant and much thicker to ensure both - 100% sealing plus additional noise and heat insulation.' Already tested for years (from 2012 and counting up) on fast roads and track. They are designed to solve the issue with the OEM forever. The Jass Performance Uprated Upper Shift Boots are direct replacement to the OEM ones for 5 and 6 speed gearboxes and for MK1, MK2 and MK2.5 model /NA, NB, NBFL/. The OEM ones tend to last a year (on a daily driven cars) and the smell, heat and noise soon again find the quckest way into the passenger compartment. 'Regularly changing the shift boot is annoying and expensive. Pricey at $72.21 USD including shipping, evidentially it ships from UK or Bulgaria, depending on availability and postal price.
